V2 EGR Valve Issues

[snopro_69]

Any of you cold winter guys see your EGR cycle on a regular basis on the lower tunes all winter long?? Warming up above freezing here now and running the 150 but still wont cycle. Thanks a bunch!!

[Heavysledz]

same problem here in Idaho. No EGR cycling since I installed my DD over 2 months ago. It has been in the 60's and still doesn't cycle at all.

[Tech1956]

Its 80 Here In South Florida & Mine Does Not Cycle With Any Of The Tunes 150 Thru 250. Have Not Tried Any Of The Lower DPF Off Tunes, Like The Power & MPG To Much :cool:

[64forsure]

Mine cycles all the time at idle once the truck is up to temp, I'm also in Idaho. However, that's running the 210 tune. I have my DD set to alert me when the valve is open at all, that way I know when it's opening and I can check for white smoke out of the tailpipe!

I guess since there are so many folks that don't seem to have theirs cycle at all and other like you that do, we need to try and determine what is the difference. I think we can almost rule out temperature since we have reports from almost every climate and temperature swings from below zero to temperatures in the 80's or higher. I think these questions below are a good starting point to try and determine if it is related to a specifc rev of tunes or if it is totally unrelated to Spartan at all. Regardless, there has to be something in common between all the trucks that don't see the EGR cycle. The key is trying to figure out what that commonality is.

1. What version of Firmware is your DD
2. What version (release date) is the tune(s) you are running.
3. What build is your truck (i.e. Job 1,2 or 3 and beyond)
4. When did it stop cycling or has it never cycled.
5. If it does cycle, what are the conditions:
- ECT
- EOT
- Ambient temp
- What tune (including what rev.)
- Driving condition (idle, Park, hwy speed, etc...)
6. Anything else you think might be worth mentioning.

[6.4Ltony]

I think that temp has nothing to do with it.
1. latest (tuner/tunes purchased in Jan 2011) Truck is a manual trans.
2. last modified 2/28/11 so probably new. These are .enc files for the zf-6.
3. she's a 2010 built for me in Oct 2009.
4. NEVER CYCLED
5. have run 40 and 75hp tunes only (all manual trans tunes are dpf off)
6. No codes.
I hope it can get resolved as I would like that to cycle. I have driven approx. 500 miles since tuning. I think this issue has to be related to the tune and not any specific truck.

[snopro_69]

-latest version of tunes and DD im sure (only month an bit since boughten)
-early 2008 job 1
-ran 210TP,250, Now 150 trying to get it to cycle (might try stock DPF off tommorow)
-been below 0 C here since i got it but now warming up and still no cycle

[kylebryan]

I too have the latest tunes installed (v2) and my egr has not cycled since the update. I agree that the temp has nothing to do with it since mine didnt cycle when it was 11 degrees and hasnt cycled on our recent 87 degree days. I loaded up the stock no DPF tune today and i see the same issues, no cycling at idle or while running down the road.

I talked to jeff today and he was going to get with Matt to see if there was something possibly wrong. Hopefully he will get back with us with an answer on whats going on.

[jared64]

My dd is the latest, my tunes are up dated, It will cycle on warm days and on cold days. Its random but it will cycle 250,210t,210 at idle about 38% for 4 sec then shut off. 150 and lower it will always cycle all the time. My truck is job2. The truck will cycle when its 5 degrees and when its 85 degrees. I agree that it has nothing to do with temp.. Just my experience with this situation.

This is why I don't believe there is a problem, or if there is one it is very isolated. This is the only forum out of the 4 that I monitor where I have people mention not seeing the valve cycle. Obviously there are quite a few having the issue here, but there are also people not having the issue.

Like Kyle said, I text Matt tonight about the issues he (Kyle) is having. Hopefully I will hear something soon.

[kylebryan]

i honestly dont think this is a parameter a lot of people will monitor unless they are made aware of an issue or are curious is theirs is cycling. I think its time that I make a post on other forums to see if people are seeing the issues that many of us are seeing just to see how many ppl are actually experiencing this issue.

Jared64/64forsure - could you do me a favor and let me know when you actually updated your DD to Firmware ver. 2.1.2-1949 or when you bought it if it came all ready updated as well as the new tunes. Also, are you able to see the EGR delete tunes on the DD when selecting what tune to load?


kylebran/snopro_69/Tech1956 - Can you also let me know when you updated to Firmware ver. 2.1.2-1949 or if you purchased your DD with it all ready updated. Also, are you able to see the EGR delete tunes on the DD when selecting what tune to load?


Trust me, I am going somewhere with this but want some more input before I decide if I will say anything.

[Tech1956]

I Purchased Mine With The Latest v2 Tunes, Job2 Trk.

[kylebryan]

ive had my setup for over a year and update the tunes every time they come out. I also upgraded to the new V2 license and v2 tunes a couple weeks after Matt released them.

[64forsure]

I've had my DD setup since they very first came out with the DD XL in 2009. I too update my tunes every time updates are released. I haven't had my EGR valve plug up on me in quite a while. When it does, I run stock and try to free it up, which has been working. I know when it plugs up, because I get a CEL, and EGR codes in the system. At least that's what it used to do. But like I said, it hasn't plugged up on me in quite some time. It's still pretty cold out here in Idaho, so we'll see what happens once it warms up some.

[Heavysledz]

When did you purchase it and can you see the EGR_OFF tunes on your DD?

[Heavysledz]

Thanks...can you see the EGR_OFF tunes on your DD?

[08stroker250]

Kyle doesn't have a level 3 license. You have to have a level 3 license to get the EGR delete tunes.

Thanks...couple more questions. 1.) When exactly did you do the upgrade to V2. and the latest tunes 2.) can you see the EGR_DELETE tunes on your DD?

[Crack85]

Kyle doesn't have a level 3 license. You have to have a level 3 license to get the EGR delete tunes.

I have a level 3 license, and only have dpf on and dpf off tunes....

[Heavysledz]

Kyle doesn't have a level 3 license. You have to have a level 3 license to get the EGR delete tunes.

Thanks Jeff....that I didn't know...now I do. I am trying to determine a couple things...

1. Are the folks reporting no EGR cycling all running the latest release of tunes. So far it appears so.

2. Did they buy their DD with V2 pre-installed and the latest tunes all ready on it or did they have an older rev of firmware in which they updated themselves and then downloaded and installed the latest tunes.

-64forsure: Has the latest firmware and tunes but updated from an older rev and downloaded and installed the newer tunes. He is seeing his EGR cycle.

-Kylebryan: Has the latest firmware and tunes but updated from an older rev and downloaded and installed the newer tunes. He is not seeing his EGR cycle.

-Tech1956: Has the latest firmware and tunes but purchased it pre-loaded. He is not seeing his EGR cycle.

-6.4Ltony: Has the latest firmware and tunes but but purchased it pre-loaded. He is not seeing his EGR cycle. (Has manual tranny so may not be the same scenario???)

-Heavysledz: I have the latest firmware and tunes but purchased it pre-loaded. I am not seeing his EGR cycle.

-Crack85: Has the latest firmware and tunes but purchased it pre-loaded. He is not seeing his EGR cycle.

-Snopro69: Waiting for feedback

-Jared64: Waiting for feedback





So what do we know.

1. So far all reported cases are running V2 firmware and the latest tunes.

2. So far nobody that has recently purchased their DD with the V2 update and tunes pre-installed has reported that they are seeing their EGR cycle. (need more user feedback)

3. All job trucks effected.

I think we need more folks to chime in so we have a larger pool of data to look at. But at least this is a start......

I have the latest firmware and tunes but purchased it pre-loaded. I am not seeing my EGR cycle.

[Heavysledz]

The no EGR_DELETE tunes appears to be more common than I initially thought. Mick and Matt are aware of it so I will wait for them to respond on what may be the issue.

[Five7Ranch]

I am not seeing my EGR cycle at all either.
Just purchased it 4 weeks ago from Spartan and have tried every tune and no cycling.
Job 2 truck. Level 2 lic. Cant see any EGR delet tunes.

[Heavysledz]

I've had my DD setup since they very first came out with the DD XL in 2009. I too update my tunes every time updates are released. I haven't had my EGR valve plug up on me in quite a while.

Since you are one of the lucky ones that are actually seeing your EGR cycle, could you confirm exactly what parameter you are monitoring (Ford specific or Generic ONBII) and what you have your DD set to as far as the gauge range, high and/or low limit warning, and alarm setting.

I would hate to find out we are watching the wrong parameter or have the DD parameters set wrong for monitoring it correctly.

[Crossfire7]

i have all the latest firm ware and v2 tunes and ive been looking and my egr is cycleing to 33% the other day sitting in the drive through teller line at the bank it was cycleing like crazy could hear it every 10-20 seconds

[Kimminau2]

Other than setting the DD to show EGR cycle, how would you know if it is cycling or not? And what does it hurt if it cycles or not? I thought the 250 and higher tunes had the EGR shut off anyway.

[Crossfire7]

oh ya im running the 250 tune ....... if u listen to ur exhaust it sounds like a hair dryer turning on and off someone else have to answer trhe rest for u i gett a lil confused with all the info on here

[6.4Ltony]

1st to thank SnowPro and HeavySledz for getting a chat going on this topic.
I have some ideas:
1. Make it a Sticky until resolved.
2. Keep the topic to......well.........the topic. No ancillary questions. It is about EGR cycling "yes" or "no" and lets stick to Heavy's format. Honestly this will help the powers that be at Spartan get the issue resolved.
3. Other things like "why should it cycle" or "who cares" or "is your grandma single" can be started as separate threads......no?
4. My opinion on "is it" or "isn't it" cycling is.......does it appear on the dashdaq when monitoring "EGR_%" or not. I don't care if your Navistar 6.4L hums, whistles or plays Bethoven's 9th Concerto....if the software doesn't recognize the EGR cycling it isn't.
Feedback.....

Crossfire7 - Can you please confirm if you updated your DD to V2 firmware and the latest tunes or if you purchased it recently and it came preloaded.

[Heavysledz]

Request granted!

Thanks Jeff

[Crossfire7]

i updated it myself to the v2 with the new tunes in late November i moniter command egr in the generic obd2...... if u want me to switch tunes i can try c what other tunes do just let me kno which one

[irocpowerstroke]

i got the latest for jan 2011 installed it with mick's help my egr do not cycle at all my truck is early job 1 running the 250 tune,never tried any other tunes like the fuel mileage on the 250.sorry the weather here have been -35 and now plus 6 still no cycling.

[rihale535]

I bought my tuner with pre-loaded tunes last December 2010 (V2 software) from Spartan...I'm running the 210 tune and my EGR cycles. I have a Job 3 truck.

[youngj]

I bought my DD October 2010, came with V2. 1 month ago I know my EGR was cycling normal, I will confirm again today and repost after I check again. I also have an 08 Job 3...I noticed of the few that say theirs is cycling seem to be Job 3 trucks?

[Crossfire7]

i have a job 3

[youngj]

Well maybe I was wrong. Switched to monitor the EGR for about 35 miles today, 7 minutes of idling included, on the 150 DPF off tune and never saw it leave 0. Maybe mine isn't functioning properly anymore either?

[snopro_69]

purchased mine with the V2 loaded on it.. only have had it for maybe two months now... goin to try the stock DPF off one tonite.... and i am level one so cant see the EGR off tunes. never seen it cycle.. hope something gets figured out

[BIGCHRISC]

I installed my tuner in late 09 I updated to the V2 myself and my Egr cycles on all tunes 250 and below.

[jared64]

Heavysledz, sorry its taken me a little bit to get back to ya. I bought my tuner through ptp, and it was the last part of september so it came with the latest version. When i purchased my tuner i only had a level 1 license. Since then i upgraded to a level 3 license through spartan. I do not see egr off tunes on my dd. Mick did say a week ago that they are on there though, so if i wanted to go a egr delete that tuning would be easy because those tunes are there. I hope this helps as a starting point. Let me know if i can help more.

[Beene]

One of the last Job 1 350's. Level 2 purchased from Spartan in Feb. 2011 with current firmware and preload. No Cycle on any tune. Monitoring both Ford specific and generic OBD. Min=0 Max=100 Warning currently at 1. Only other mod is the AFE down pipe back 4"

[fg250]

job 1 truck, bought the tuner 5 ish weeks ago, haven't seen the egr cycle on the 175 or 210. the only other tune i ran was the 275. i have a level 2 license and no egr delete files are shown on the dd. although when i made a copy of my sd card onto a cd, you could see them there.

[Heavysledz]

Thanks to everyone for there input/feedback. I will put all of this into a spreadsheet as I can't seem to find a simple way to track it via the forum. I will post it up later today (hopefully). So far, everyone that is reporting this issue is running the V2 firmware and the latest tunes. Only a select few that are running the newest tunes are fortunate enough to see there EGR cycle but none of these were purchased preloaded and were upgraded from an older version of firmware.....not sure what this all means but stating what has been reported so far....

[Heavysledz]

Everyone - Here is a snapshot of all of the input I have received from everyone to-date. If you can review your specific information for accuracy and provide any of the additional info that I am tracking that would be appreciated.

I will post the updated spreadsheet every couple of days so we can see what the data reveals.

So far we have only received input from folks running the V2 firmware and latest tunes so we can not rule out the issue is only related to this rev. at this point. So far it looks like everyone who purchased their tuner since the beginning of the year do not see their EGR cycle.....lets see what the data reveals after some more input.

[6.4Ltony]

That's quite a lot of work. Thanks again.

Nice Job!
I Purchased My DD 1/10/2011 W/v2 Preloaded - River City Diesel
Level 1 Lic.
Thanks.

[kylebryan]

my truck is an 08 job 1. Original purchase date was 2-10-10.


I have seen a few times where people think they "hear" the egr cycling but it turns out its not. Anyone who is "hearing" their EGR cycle please confirm it actually is by watching the parameter on their DD to verify cycling of the valve. I just dont want any loose ends here guys.

[kylebryan]

I just thought of this and thought it might be worth a look. when i upgraded to the v2 software i installed a new exhaust system with no bungs in the exhaust so therefore i didnt use my exhaust sensors. Now i know that the sensors are supposed to be disabled in the v2 tunes but im curious if this could have anything to do with the egr not cycling. Post up if you still have all the sensors still installed in your exhaust system. Worth a shot anyways...

[Heavysledz]

Thanks guys....I will keep updating the spreadsheet and post the updates every couple of days.

Nice thoughts....keep them coming. If you think it is worth tracking, I can add a column for tracking whether or not you have your EGT/ pressure sensors connected or not. My EGT1 and EGT2 sensors read 1472 degrees when disconnected. I wonder if this could be preventing the EGR from cycling because the ECM sees high EGT temps as compared to the EGRTA temps???

rihale535 - jared64 - BIGCHRISC - 64forsure - Crossfire7: Can you guys please confirm if you are running your exhaust system with the EGT and pressure sensors in your exhaust system since you are all reporting that you are seeing EGR cycling?

[youngj]

I think this is on topic...I was monitoring commanded EGR %'s on both ford specific and generic with no movement. So i started searching around for other EGR parameters to monitor and selected EGR_ERR%. Anyone know exactly what this is? The preset limits are -100 to 99. Upon startup, I'm showing -100, and occasionally itll move to 99, and then return to -100? Not sure what it means, just throwing more confusion out there I guess lol

[jared64]

Yes i have my sensors in my exhaust system

Valid question....you got me.....maybe Jeff or someone with some more knowledge on all of the parameters could comment.....

[Heavysledz]

Yes i have my sensors in my exhaust system

Interesting....do you have the ability to disconnect them and monitor your EGR for a day or so to see if it continues or stops cycling? It would be awesome if we could find the smoking gun!

[Crossfire7]

all my sensors are in my exhaust

[Heavysledz]

all my sensors are in my exhaust

Looks like we may be on to something! Thanks for the feedback...

Does anyone who is not seeing the EGR cycling have an exhaust system that has the bungs in it or possibly have the sensors all ready installed but not hooked up? If so, could you hook them up and monitor for EGR cycling. My system doesn't have the bungs installed so I can't easily check.

[youngj]

No sensors on the truck, left em attached to the DPF when it was removed. Nothin but straight pipe.

[Heavysledz]

Awesome...keep the data coming...We may be on to something!

[Tech1956]

No Sensors On My Trk. Pigtails Taped & Tied.

[Five7Ranch]

Just looked at my back up files on my laptop and there is a file for each tune
xxxHP_1_negr.gtf. Could that be the EGR delete on each tune? I dont see an EGR delete tune when I am tuning the truck with the DD.

If you have a level 3 license, you should see the EGR delete tunes. Myself and a few others have a level 3 license and do not see them on the DD. Mick said there is an issue with the index file and was checking with Matt and would get back to me when he heard something.

Those tunes are created for when you delete your EGR system.

I have a level 3 license and I don't see them on my DD either.

[Heavysledz]

I only have the Level 2 license

Than you are OK. All the tunes are on your dashDAQ as you noted from your backup file. The level of license you have determines which files you have access to on your DD. If you purchased a level 3 license and uploaded it, it would then allow you access to all of the tunes up to 310 including the EGR Delete tunes.

Jeff - Please correct me if i am wrong.

[Heavysledz]

I have a level 3 license and I don't see them on my DD either.

Shoot Mick an email or PM him and let him know.

[Hirshornj]

I have started monitoring my EGR, is has not been cycling either.

Just purchased the tuner this month. Latest update. I have a CAI, and DPF/DOC delete pipe installed, no bungs/sensors.

[Barefoot40]

One more truck for the spread sheet. I have a job 1 with no cycling on any tune. I updated to the new version 2 in late Feb 2011. I did have cycling prior to updating to the new V2 tunes. Origional tunes were purchased in june 2009

Yesterday thew a code P1135, and puking lots of black smoke, and min throttle at low boost this may or may not be related.

Can you provide a bit more information.....

-Original purchase date of your DD/Spartan tunes
-Are your EGT1,2,3 and pressure sensors all hooked up to your exhaust system.
-Specifics on your exhaust system.(i.e. DPF delete or DPF/DOC delete, or full system etc...)
-License level (1, 2, or 3)
-When did you start noticing the lack of EGR cycling?



The P1135 code is: "P1135 Pedal Position Sensor A Circuit Intermittent"

[Heavysledz]

New info added....

[Heavysledz]

I disconnected my sensors and will see in the next day or so if my egr keeps cycling. Ill keep ya posted.

Thanks....I appreciate it.

[rihale535]

Sorry i didnt get back to you sooner....
Yes I have all sensors in my exhaust
Level 1 license

[Barefoot40]

One more thought on this egr cycling. After I switched the new V2 i had my dpf on, and it did cycle. After I took off the dpf and switched to dpf off tunes no more cycling.

[Beene]

Stock intake, down pipe back exhaust, no sensors in exhaust

[Heavysledz]

Sorry i didnt get back to you sooner....

Thanks...I will add this to the spreadsheet tonight when I get home...

[Heavysledz]

So obviously when you had your DPF on, all of your sensors were still in your exhaust. When you took off your DPF, did you leave the sensors in the stock exhaust or did you re-install them in your delete pipe and reconnect them?

[64forsure]

I look at the commanded EGR % parameter. I usually see it cycle up to 40% I have the alarm set to anything over 1, so that it alerts me whenever it is open any amount, it says "alert". I am surprised at how many don't see it cycle. It's pretty much a guarantee for me that it will, whenever I am idling and the engine is warm. I've been running the 250 tune, and it has been cycling at idle normally.

I Hooked Up Our IDS / VCM Ford Diagnostic Lap Top To My Trk. Just To Verify That The EGR Is NOT Cycling. It Is NOT. Now Have 210TP Loaded

[kylebryan]

you can go ahead and put me down for no sensors in my exhaust. I also dont have the bungs in the system so i cant put em back in to test with..

[fg250]

my dpf delete only pipe has no sensor

[Five7Ranch]

No sensors in my exhaust. No bungs to reconnect.

[Barefoot40]

Sorry for the delay. I have a basic level 1 licence, with a dpf/doc delete. The new straight pipe has no bungs so I left the probes in the old dpf. I have been monitoring the EGR Command_%. I noticed the cycling stopping as soon as I went from the dpf-on tunes to the dpf-off tunes.

Looks like my egr may have gone bad. (Working with Mick now) Willl upate as soon as I am sure.

So are your EGT1,2,and 3 sensors and pressure sensor installed in your exhaust?

[Heavysledz]

Do you have the ability to reinstall (even if temporarily) your EGT probes and re-test.

[Barefoot40]

I dont have that ability any more without reinstalling the whole dfp/doc unit.
Feel free to call or pm me if its easier.

It looks like you might have a couple of issues here. The P1135 code is related to the throttle pedal position as far as I can tell.

Once you removed your DPF (and temp probe), you stopped noticing the EGR cycling. Are you getting any EGR related DTC's?

It is starting to look like there is an association between the removal of the EGT1,2,and 3 sensors (and possibly the pressure sensor) and the lack of EGR cycling. I need a few more folks to respond with wether or not they have theirs installed in their delete pipes before we can draw any conclusions.

Thanks...I was hoping maybe Tech1956 could since he has access to a IDS / VCM Ford Diagnostic Lap Top and it would confirm almost immediately it the truck was in park and idling(with an appropriate tune loaded).

[fg250]

you're doing an awsome job tracking this problem down, i think your hunch is right...keep up the good work!

[Barefoot40]

Sorry for the wrong code. It is a 1335. not 1135. My mistake. I am getting a 1335 EGR max.min error. Mick thinks the egr is stuck and suggested running it hard to try and break it free.

[6.4Ltony]

I am wondering what Spartan's plan is for resolving this, including timeframe.

[Heavysledz]

I am wondering what Spartan's plan is for resolving this, including timeframe.

Lets not get ahead of ourselves just yet. I think we are all doing a great job of keeping on subject and providing specific information that we can compile and then review for trends or specific configurations that may or may not be seeing a specific issue. I think we are headed in the right direction and after a bit more data, I will see what it reveals and then I will discuss with the Spartan guru's and see what they think.

If we confront them with a few inputs that appear to point toward a certain direction and demand a fix, I am sure we will get just the opposite response than what we are hoping for in return. However, if we do our homework and gather enough supporting information, and present it to them in the proper manner, I think they would be more open to listening to what we are saying.

I would expect the same in my line of work. So I am showing the same courtesy to them.

Aside from waiting on specific feedback from BIGCHRISC, 64foresure, Jared64 and possibly Tech1956, if anyone else has the ability to re-install the EGT sensors and test or disconnect and test based on current setup and see what results they get. This would go along way to proving or dismissing this theory.

If we can show that connecting the sensors back up, causes the EGR to start cycling (for those of us that are not currently seeing it cycle), and those that are seeing it cycle, disconnect theirs and see if their EGR cycling stops cycling. This should be sufficient to either validate or disprove this theory.

[Sathinas]

The sensors are installed in the exhaust here, but haven't seen the EGR open either. Then again, I haven't set a warning for it.

I'll set a warning on the PID and monitor it for my trip back home, about 980 miles worth. Will report then.

Thanks, I will add you to the list once you confirm if you are or aren't seeing the EGR cycling since you haven't yet monitored it. Let me know when confirm one way or the other.

Someone on another forum posted up that they haven't seen their valve cycle and they do not have the V2 update yet.

He didn't directly say that he did not have the V2 update, but since he purchased it in July and has not updated the tuner, my guess is that he does not have the V2 software update yet.

[jared64]

Ok guys here is my results from my findings in the last 12-18hrs. I disconnected all my exhaust sensors and my egr did not cycle at all during the day. I crawled under my truck tonight(while it was still warm)and plugged all three back in and my truck started to cycle the second it was started. I shut my truck off unplugged them again to be sure and no dice. Plugged them in 2 min later and it cycled. Hope this helps.

2008 Job 1 level 1 tunes with DPF/DOC delete no sensors and CAI Purchased in Dec 2010 from Cobb Diesel Performance. No cycling since install and I have tried all tunes including stock DPF off.

Not everyone can log in. Some people neglect that portion of the email sent out for registration and never get set up for this forum. There are roughly 11,500 Phalanx units out on the market currently. This forum has slightly over 1,000 members, including members who probably don't even own a 6.4 anymore. My guess is that there are anywhere from 500-750 active Spartan owners on the forums (all of the forums). By active I mean on the forums at least once a week and viewing threads. That is less than 1/10 of actual Spartan users out there. Of those active people, 50-100 of them may have a username setup here. 25 or so MIGHT view this forum on a regular basis. Forum users are a very small percentage of the actual number out there. My guess is that a huge portion of people with Spartan units have the issue and don't know it, and probably will never know it. We have about 75 or so people that frequent this forum....out of the 1,000 or so that are members. Pretty low numbers. Getting the word out would be pretty hard.

Sorry for the long post by the way....I'm kind of bored lol

[Heavysledz]

haha....yes, too much time on your hands if you can crunch those kinds of numbers. I guess we can only focus on those that are willing to participate or care to keep up with what they have purchased. I guess if they start having issues, they will eventually touch base with Spartan to see if there is a fix. Do you know how many people have upgrade to or have purchased a tuner with V2 updates?

I'm only online because I am ripping and burning blu-ray movies...it takes a while when you are dealing with 40GB file sizes....so there is a lot of waiting and watching.

[08stroker250]

I do not have those numbers. I think the number of pre-V2 users that have upgraded is pretty small. There are still a handful of original tuners out there that have never been upgraded to the strategy flash style. The number of V2 users will definitely increase over time, especially as people find out that they cannot update their tuning files without having the V2 software. Well....they can update them, they just won't work.

As far as the number of V2 tuners out there that were sent out as V2 tuners....I am not sure of that either. My guess would be in the 300-500 range. Could be more than 500, but it could also be less than 300. I don't work in sales, so I can't say for sure.

[Heavysledz]

wow...even 300-500 is a lot....

[08stroker250]

wow...even 300-500 is a lot....

In comparison to how many units have been sold since 2007, I would say that 300-500 in a 6 month time frame is a pretty low guess. The economy is down though, so you can't expect as many people to spend $1250 on a luxury as you could a few years ago. We have a TON of dealers out there also (over 100)....so looking at it from that perspective, 300-500 is once again a pretty low number for a 6 month time period. This number crunching could be way off for all I know. LMAO

I don't have the bungs in my exhaust but if it will help I can climb under and put the sensors in and just run them off to the side. Not sure if it will do anything though since it will never see the exhaust temp rise but if it will help lmk

[Sathinas]

Alright, EGR opens here. ~24% at idle, twice in about 3 minutes worth of idle while chatting it up with someone. It hasn't yet opened at highway speeds while cruising. Don't know if it's supposed to, though I vaguely remember reading somewhere that it may.

Depending on the Tune you have in it may not open off of idle. I believe the 150 and down open while cruising and the 250 is only when idling.

[Sathinas]

I'll have to check which tune I've got loaded. It's either the 250 or 275.

[Beene]

I'd suspect the 250 since the 275 completely shuts off the EGR

[Heavysledz]

Jeff - Can you clarify which tunes will cycle the EGR and when (i.e. idle, Park, hwy speeds etc...). Hopefully this will prevent anyone from claiming they are not seeing the EGR cycle when they have a tune loaded that doen't cycle anyways.

Sathinas - I will add you to the dreaded spreadsheet tonight when I get home. :)

Beene - If you can connect your sensors and tuck them up on the frame out of harms way to see what reaction you get (if any), that would be great. I plan on doing the same thing but it might be a day or so before I have a chance. My hunch is you need to see some heat on the probes or it will not work correctly......who knows until we try it.

Tech1956 - Thanks for the info. Not sure how to interpret that other than it looks like it is not looking at the EGT temps of the EGR valve during your test? Would be interested to see what it says if the 3 EGT probes were hooked up?

Actually it really does not matter if the Exhaust Gas Recirculation valve does not cycle, it is a bonus unless you plan on going back to a "SLUG" Stock emissions engine. If that was the case we would not have tuned engines. Its as if you had a EGR Delete Tune, as with the "Higher Tunes" so I would say embrace it until You have a problem. Just My Opinion until I have a problem, but as with allot other people that are tuned with no problems run with it. Don't mean to ramble

I think it has more to do with the temperature readings when they are disconnected. Mine read 1472 degrees when disconnected and I am sure that would be too high to consider opening the EGR and recirculating the exhaust gases back into the engine.

[Heavysledz]

To me this seems like it would be a pretty important update to get out to the people not using sensors in their exhaust. I realize their is a work around for this but will this fix be in our next update?

[Billy_Pilgrim]

Howdy all, new member here. I just purchased and installed my DD (new) with V2 software, 125 tune no DPF. AFE CAT/DOC and DPF delete pipe. AFE STG2 Intake. 08 F250 CC.

I have 2 sensors connected (tied up, not in exhaust) 3rd didn't want to come out of DPF so plug is taped and tied. No pressure sensor connected. I will monitor and see what happens with EGR, if need be I will then connect the 3rd (once I can get the stubborn thing out of DPF) and see if starts cycling.

I am new to DD and monitoring, if someone could give me a quick reply to which signals I should use for EGR cycling I would appreciate it, thanks all!

[kylebryan]

comanded egr is what you need to monitor. WHen the valve is closed its at 0% and when its open its anywhere from 1% to 40%. Ive personally never seen mine open more than 23% but ive heard of peoples opening more. The best way ive seen to remove those stuck sensors is to take a small pipe wrench and muscle it out. The pipe wrench has the ability to grip more and more the harder you pull on it. I think you have to have all 3 EGT sensors plugged in for the EGR to cycle.

[fg250]

I'm going to take the sensor out of my dpf and plug it in under the truck to see if it will start working...though i probably won't get it done for a couple weeks because I'm working 6 10's and night shift to boot!

[fg250]

although maybe I coould just make a jumper for the plug under the truck to make the connection instead of having my sensor under there exposed to all the road salt

[Beene]

Installing the sensors again now but one won't come out so I'm going to see if it will still function with just the one. Jumping straight propably won't work since it should look for some type of reading but I figured that the sensor was just a basic thermistor so I tested with my DVM and it rests at about 216ohms in my shop at 20 degrees celcius. It increases resistance as the temps rise so I think I'm just gonna jumper a 250ish ohm resistor across the 2 terminals, read what the DD says for temp and see if it starts cycling. May be a good quick fix for the people who either don't want to or can't leave the sensors plugged in.

Edit: Where is EGT Bank 1 Sensor 3? Sensor 1 and 2 are the ones around the DPF but where is the 3rd?
Edit: Found the 3rd sensor further back. I didn't even remember removing that one! I put a 270 ohm 1/4 watt resistor in all 3 EGT connectors and immediatly my EGR started cycling up to 25%. Sensors are DEFINATLY the problem!

[Barefoot40]

Nice work!!! Thank you.

[Beene]

Just to cover my a$$ I AM NOT A FORD TECH! This is just what I'm doing on my truck and it's working. Do so at your own risk!

[Billy_Pilgrim]

Consensus seems to be with the sensors. As to my previous post I only have 2 of them plugged in and tied up under the truck. Drove 30 miles and did not have a single EGR cycle of any %. This weekend I will plug in the 3rd and see if EGR starts cycling. So far it looks like it will, but can't hurt to confirm.

[kylebryan]

I think you will need all 3 temp sensors plugged in but it should cycle while just idling.

[soup4856]

Are there any long term issues with not having the EGR cycle? 08 Job 1 V2 with no sensors and EGR is not cycling. I have been running the 210 and it does smoke a little under full throttle. I really don't care if it doesn't cycle as long as it doesn't start throwing codes.

[Beene]

In the long term the valve can get stuck shut and throw codes. It can also make it impossible to go back to stock for warranty or the like. I've always wondered why this is a problem on the 6.4l and wasn't on the 6.0l. I had my 6 tuned for almost 2 years and when I sold it I detuned, plugged the valve back in and off it went.

[08stroker250]

It won't throw codes. If it was going to throw codes, it would have already done so. The only issue is that your valve could stick closed.....which isn't a bad thing. Some people don't want that to happen. Others brush it off because they don't care or they know how much it's actually helping their truck.

[Barefoot40]

I had my truck towed to my mechainc and had the dpf rehooked up today as my truck would not run and was throwing a 1335 code ( EGR). After the dpf and associated sensors were rehooked up it started cycling and is not throwing the codes and is running fine. I never had a check engine light just the 1335 code, and lots of black smoke. My mechanic had the independant opinion that the sensors monitor the exhaust temp which in turn regluate the EGR. Some peoples egr's seem to stick open or closed, not sure where mine was but it smoked really bad!!! (not good smoke) and had no throttle response to the point it would not run.

Jeff if you could pm me on this I would appreciate your time.

Your EGR valve was hung open going by the description.

[64forsure]

Hey Jeff, do the EGR valves ever get stuck slightly open, allowing a little exhaust in the intake all the time? I have wondered about that with my truck, because it definitely smokes more than it did when I first installed my tuner, which was over 40,000 miles ago.

Typically if a valve sticks open, it is due to a valve failure. My dad's bone stock 6.4 had this happen last year. He was driving down the highway running about 75 MPH one day, and the truck lost complete power and started smoking badly. The truck wouldn't move at all. It would just smoke badly and rev up. The diagnosis was a valve failure. The valve had hung completely open.

Of course, that was an extreme scenario. The valve can also stick partly open. That causes the truck to run rough and smoke constantly. The truck would still be drivable in this case though.

[Kimminau2]

I can only find EGR Err%. Where do I find the parameter to monitor for whether or not it is cycling? I have a bunch more parameters that are blacked out but still did not see EGR command %.
I have a level 1 license.

[Beene]

You're to far down. It's "commanded EGR"

[Kimminau2]

That was it, thank you.

I have the 250hp tune loaded so it should only cycle at idle, correct?

If I load the 210TP it will cycle normally, correct?

[BigBlue08]

Both the 210 and 250 cycle on idle..

[64forsure]

Tunes under 210 cycle off idle as well.

Both the 210 and 250 cycle on idle..


This feature has not yet been fixed for all trucks. If you don't have your exhaust sensors plugged in, your EGR likely wont cycle.

[teamscheff]

Does the coolant need to be at a certain temp before it will cycle? I have all the sensors installed, just tried it out in the driveway and so far did not see it change. I just updated everything a couple weeks ago to the V2. Running the 210 tune but didn't let it warm up very much ( 120 degrees or so ).

[Beene]

I've never seen mine cycle unless the coolant is over 130 degrees

[teamscheff]

Thanks Beene, I let it warm up to about 170, restarted the engine and it cycles to about 34% then back off so it seems to be working.

[Kimminau2]

I have the 250 loaded, mine cycles for a few seconds in idle after it is warmed up. Goes up to about 25%.

[Heavysledz]

Thanks Beene, I let it warm up to about 170, restarted the engine and it cycles to about 34% then back off so it seems to be working.

I found the sweet spot somewhere between 130-140 before it will start to cycle.

[snopro_69]

ya thats what mine does too once its warmed up and restarted...but they keep saying its suppose to cycle at idle the whole time its idling in park and drive so thats not working correct then right???

I am new to the Spartan world. Just got my CAT/DPF off my 2008 and am running the 75HP tune...I'm really impressed with the product...

I have been reading that the EGR's for diesels in general are bad and typically cause problems down the road. I have a 6.4 and am thinking about the Sinister Diesel EGR Delete kit for $199. Does my Spartan tuner support an EGR delete?...Do I have to run a certain tune or are any of the tunes good for an EGR delete?...Would this be a good idea?

Should I just leave it alone?.....Any suggestions would be greatly appreciated.

Thanks - John

Thanks for the info.....Spartan is now aware of the issue and will be releasing a fix sometime in the near future.

[j21black]

Sounds like the new update fixed this problem.

I didn't have the issue as I had my sensors installed.

Folks have been reporting their EGR valves are cycling with the update.

[fg250]

i just loaded the update today and on 210 tune the egr was cycling at idle...much happier!

[NicksF350]

What update are you talking about? I have the V2 software that I purchsed 4 months ago... Do I have the update or did Spartan update again to fix the EGR issue?

If so, how do I update??

[6.4Ltony]

i loaded the new 40hp tune and the EGR valve is not cycling at all (idle or under load). This is a manual transmission truck so requires different tunes compared to the auto guys (and girls). Does anyone want to load the 40hp and see if the EGR works (the no dpf tune)?

[jared64]

im doing it for ya right now, i have auto though.

[6.4Ltony]

thanks a lot. I appreciate it very much. I had the resistors in the sensor holes w/ the old tunes and the EGR valve cycled at idle......under load, seemed to be doing great. When i uploaded the new tune I removed the resistors and the EGR ceased working.

I imagine that the engine management component of the tune files are the same (?) for auto and manual transmission, either way it will be interesting to see.

[jared64]

hey, 6.4ltony I loaded the 40hp dpf off tune and my truck cycled like crazy. With that being said my truck cycled on the old tunes as well. That was the first time running that tune also. I have my stock sensors in my exhaust hooked up. Let me know if i can help more.

jared

[6.4Ltony]

thanks again. Since you have your sensors installed and I don't that may be the issue, although the tune is supposed to work w/o sensors. I will load a different hp tune to see.

[6.4Ltony]

maybe if someone is bored and wants to load the 40 or 75hp tune up.....someone w/o the exhaust sensors installed in the exhaust that would also help.

[BigBlue08]

I have a bungless pipe and it does cycle without the sensors.

[Barefoot40]

I believe the issue has been tracked down to the V2 tunes that were released prior to April of this year. The issue as I understand it is that the sensors were not attached. This gave false/negative readings to the EGR so it didnt cycle.

Jeff and Matt released new tunes on April 6th that are suppose to take care of this issue. You might want to read up on the new tune release and see if that will solve your concerns.

[6.4Ltony]

i am running the new tunes.

[Barefoot40]

Sorry maybe I misunderstood. If you are running the new April 6th release is the egr cycling at tunes below 210?

[6.4Ltony]

As for me, I am running the most recent update tunes and have tried 40hp and 75hp w/o EGR cycling. I have a manual transmission........are we going to start the spreadsheet again.....ha ha? :)

[snopro_69]

i just checked mined on the 175 with the resistors in the sensors like before.It's still doing the same thing and cycling for first 5 seconds when warmed up and started then closes. (updated tunes)

[6.4Ltony]

At this point I think (for me) it would be most critical to have someone w/ a manual truck and the latest tunes and NO exhaust sensors load the 40hp or 75hp tune to see if the EGR cycles.

[Heavysledz]

can you take a look at your DD display and pick one of the gauge displays that shows the EGT1, 2, and 3 readings and tell me what you are getting for temps....

[6.4Ltony]

Sensor 1 1472
Sensor 2 1472
Sensor 3 1470

its pretty clear to me that this must be the issue. the EGR won't cycle with temps recorded that high (I think). I removed the resistors I had in so no exhaust sensors or resistors in the wiring harness.

Bingo...either you are running the old tune still or the tunes for manual transmission trucks didn't get the EGR fix. Your sensors should now be reading somewhere in the 260-300 range.

I don't know anything about the manual tranny tunes so I would suggest you call Mick and tell him what your sensors are reading and see if he knows if the tunes for the manual tranny's are going to get the EGR fix as well. In the mean time, you could use the resistors.....

[6.4Ltony]

Thanks for the idea to check those. I am running the latest tunes which are supposed to have the EGR fix.
That is good to know. Any other manual trans trucks with this issue?

[140hpHarleys]

Just had traction bars installed. (I know off topic, but give me a minute here.) When mounting the driver side bar to frame, they drilled through the main harness. Problem is fixed now, at their expense.
What clued me in to the issue was a check engine light right after they finished installing the lift and traction bars.
I cant remember the p-code, but it was listed in the DD as bank one sensor one. The temp it was reading all the time was in the 1472 range. Didn't matter what the egrt at turbo was reading. Could have been 350 and bank one sensor one read 1472. Traced the wires and, hot damn. It was one of the ones they drilled through.

[140hpHarleys]

This one is a bit off track, but applies to the topic. Move it if you want/need. Just get me an answer please.

I have a question regarding this fix, and the problem. My egr while running the 210 tune stays off. All the time. I have to run it or I get the white smoke problem. Figgrd the egr to be cracked. So, when I get the new tunes, will the egr be cycling now? If so, not so good for me...Remember the white smoke. Trying to stay away from that. Does this mean the egr off tunes will be what I need to run? Or do I have to fix the egr in order to run the new tunes, or just keep what I have and don't bother with it?

[6.4Ltony]

To Heavy:
thanks again. I reinstalled the 330 ohm resistors and the Exhaust bank sensors are in the 330 range so the EGR will cycle. I am upset only because I took the time to remove them since i was told that the EGR problem was fixed (is fixed for the auto trans......likely not for ZF-6'rs). Anyways, I will await wisdom from the Spartan gods regarding a fix for me.

If i understand you correctly you get the white smoke when the EGR cycles. The recent suite of tune updates will have the "no EGR" tunes included. If you dont ever plan to cycle your EGR i think the best fix would be to get some simple block off plates installed and then of course run one of the "no EGR" tunes of your liking.

Sounds to me like a valve issue, not a cooler issue. If you had a cooler issue, you would know it by now because your truck would have lost too much coolant and hydro-locked.

i to am gettin the code every 30miles or so...egr is not cycling when watching command egr...stays at 0....also my sensors are installed and are reading 200-300 like stated above my tuner was just updated so i have the April 6th tunes....havent loaded a lower then 250 tune yet....also any of you guys get puking with the new 250 tune now? im gettin it after i got puking tryin out the 275 tune so went back down to 250 and now still puking....Can i load my old 250 tune to see if its the tune or the truck since ive updated to the V2 stuff or no???

[badford93]

UPDATE UPDATE....loaded the 210 let run for 5mins prob no egr cycle at idle...so loaded 175....let run for 5min....no egr cycle yet again....something seems off with the V2 files im thinking....yet again i ask can i run my old 250 tune...none V2 version since i updated to V2 cuz that thing cycled fine during idle also ran fine...i really like the new shift and converter lock up on the new 250 tune though!!!

[badford93]

Okay call me an idot or what not drove to work on the 175 and about 3miles down the road egr cycle stared reading...so thats all good then...even the 175 tune in V2 still seems to boots higher then my old oudated 250 tune....anyone else notice this?

[Midlifecrisis]

I have been running the 250 tune for 2 days now. This morning I got an egr code and cleared it then drove to work. I have no idea whether or not I am cycling or not--what gauges do I use to monitor? I bought Spartan package last week so I assume I have the latest updates.

[snopro_69]

Command EGR.....search on here and theres a problem with the new 250 right now not working correctly...Fix is supposed to be on its way soon

[Midlifecrisis]

Thank you!

[6.4Ltony]

The EGR doesn't cycle on my truck at all with any tune. I emailed all the powers that be on this issue and no resolution (2 months). Anyone else with a manual transmission have this issue (I am running the updated tunes)?

[6.4Ltony]

I should add that Mick told me it was being worked on. I am just wondering if, on the lower tunes, folks with the manual transmissions are still having EGR issues.

[sdetweil]

I know its being worked on, but do we have a target for the 250 EGR problem?

Its a pain to clear the code every time I drive anywhere

Are you guys getting a DTC or just monitoring it and see that it is not cycling? I am running the new 250 and I keep getting a P0401 EGR related DTC. I hope this is what they are working on. Can anyone verify this? I never got any codes with the old 250.

[jaydog760]

I'm a newbie here, bought my DD in Oct 2010, uploaded the new "EGR friendly" tune this morning and loaded the 210 tune into my 08 F250 Job 3 with DPF delete (no bungs). When EOT hit 130, the Commanded EGR % went to 20.4 for a second or two and then periodically while idling :D. I then went for a short drive and noticed the valve opened while idling but when I got home it threw 2 codes :confused: : P=0401 Exhaust Gas Recirc. Flow Insufficient Detected and P=1000 System Readiness Test Not Complete. I wrote down the codes, cleared them, and went for another drive....same thing. Anyone else have this issue?

[08stroker250]

So your EGR valve is cycling, but you are getting the P0401 code?

[jaydog760]

It cycled a couple times and then stopped after the codes...then would cycle again after clearing the codes and then stopped after codes popped up.

[08stroker250]

Do you have the latest tuning files?

[jaydog760]

Yes, folowed this thread all last night and downloaded the new tuning files this morning. Uploaded the 210 tune and here I am...

[jaydog760]

Okay so I switched to the 250 tune (which I see others have posted that it pops the 0401 code) and this time no EGR cycle. I did the relearn...no codes and then cruising on the way home it threw the same code as the 210 (0401 and 1000). Will switch to the 175 tune (tomorrow) to see if I continue to have the same issue. Would the fact that i have the DPF plug (unplugged) be an issue? Delete pipe I have has no bung.

[08stroker250]

The tuning is setup for no sensors in the exhaust, so that is not the issue.

Run the 175 tune. The fact that your EGR did cycle on the 210 lets me know it is not the tune. More than likely, your EGR valve is gummed up a little from not cycling. The 175 tune should fix that issue. Run it for the whole day and don't be conservative with your right foot. The more exhaust you move through the EGR valve at a higher rate of speed, the cleaner the valve will get.

[jaydog760]

You are probably right. Bought the DD and delete pipe Oct. 2010. Ran the 210, then 250, and finally 275 tunes until now, 13k mi later. I never dropped down to the 175 tune to cycle the EGR. Thank you for the quick response and help in this matter. I will post results after my right foot can't take it anymore.....

[jaydog760]

I dropped down to the 175 tune this morning and started her up...cycled EGR for a couple seconds. Took off from the house and got on it...cycled EGR while accelerating. After the second cycle, no more cycling. I drove hard in the city and then onto the freeway where I had it at WOT for long periods...no cycling. So I stop, turn the truck off, turn it back on...and it cycles for a couple seconds. Then couple minutes later it cycles for a second time and thats it, no more cycling the rest of the drive. I start heading back home cause I'm happy that no codes were thrown...until I get home. I turn it off, start back up, cycled twice and then codes 0401 and 1000 again :confused: Should I keep it on the 175 tune for a couple days? Should I drop it lower? Should I be worried about these codes I keep clearing?

[snopro_69]

you have the updated tunes though rite??? cuz i bought mine in october too with no bungs straight pipe and after a while of figuring stuff out some of us found the problem of the EGR not working on bungless pipes.... They fixed that with the 275 for Level 1 update and I've seen mine work on all the lower tunes fine since then.

[jaydog760]

I have the new updated tunes that was supposed to address this issue. My valve would not cycle at all before, but now it does. The problem is that it will cycle 3 times after start-up and then no more cycling. Been driving around all day. I've been getting periodic codes, I'll reset and then it will cycle once more and that's it until I turn the truck off and back on where it will cycle 3 times and then stop. Strange.

[08stroker250]

Sounds like your valve is going bad....

[jaydog760]

What should I do? Is it an issue that I should take it to the dealer for (only have 38k mi)? Or load up the 275 and forget about it....

[08stroker250]

That is totally up to you my friend. If cycling the EGR valve is of no concern to you, then I would run the 275 tune (and/or the provided EGR delete tunes). If you want your EGR valve to cycle, I would return the truck to stock (unless you have a mod friendly dealer) and take it in.

I'd say it is no concern to me but I just looked through the past 10 pages of threads and came across a handful of other guys with the same issue (same thrown codes)...could we all be having a bad EGR valve? Is it common? Also, if I decide to not take my truck in, would leaving the current tune that has it cycle upon starting okay, or would it cause more harm leaving it and clearing the codes? Thanks for all your help and info...

[08stroker250]

The other guys don't have the issue anymore since the updated files came out. The only problem file since the update is the 250 tune. It doesn't cycle the valve at all (supposed to do it at idle) and it throws the P0401 code.

First off wanted to thank you Jeff for your input and knowledge, my first reaction was that my truck was broken. Although I was getting errors here and there and the EGR would only cycle 3 times and stop, I decided to deal with it and load up the 210 tune....loaded it up and took off. 1st cycle came upon start-up (normal), 2nd turning out of my neighborhood (normal), got on it several times, pulled back into neighborhood 3rd (normal and usually the last one) but...a 4th time while in park in the driveway. And no codes :D I don't get it, but I don't care....seems to be working fine and will keep it on the 210 tune until the new 250 tune comes back (to keep it cycling here and there). Thank you again for your patience for all us newbies!

[08stroker250]

No problem! Glad things are working for you!

[kevin]

OK, I have skimmed over this thread and I am confused. Never really thought or cared what the EGR was doing. Never monitored it either.


Do I need to care if my EGR Valve is cycling? and is so, Why?

If I have a tuned truck w/o a DPF what does it matter?

If I had a stock truck, then what happens if the EGR valve is not cycling?

[08stroker250]

The only concern with the EGR valve not cycling is that it will clog. If the valve clogs and you decide to run a tune that requires the EGR valve to cycle, the truck will go in limp mode. Also, if you were to return the truck to stock, you would experience limp mode if the valve did not cycle. The valve not cycling is actually a good thing though. It keeps your intake manifold from getting gummed up with soot/carbon.

Jeff, I think that my EGR valve might not be closing all the way. I get a lot more black smoke lately while driving when the engine is cold, but I also noticed more even when it's hot. It is cycling fine because I can watch it on commanded EGR % at idle. If the valve weren't seating all the way, is there a way to know without pulling it out? Will it throw a DTC if the position of the valve is hanging open slightly? Any way to test this?

[08stroker250]

It will likely throw a code for that. If you monitor it, you'll see if the valve is closing or not. If it's not on 0%, the valve is open.

[64forsure]

It will likely throw a code for that. If you monitor it, you'll see if the valve is closing or not. If it's not on 0%, the valve is open.

Yeah it goes back to 0% on commanded EGR. So I guess it must be closing all the way. My injectors are all contributing equally according to the power balance on IDS. I wonder what the issue is, I guess my HPFP would be the next thing. The P2291 code has popped up a few times now. I will change my fuel filters again and see if that helps I guess.

[RyanFelish]

Wait? I thought none of the new tunes over 175 were correctly cycling the valve? It's only the 250 tune?? Have I been confused this whole time? I've been running egr delete tunes to avoid the CEL, but if I run the 210 normal it will cycle and not throw codes?

[08stroker250]

Correct. Only the regular 250 tune has an issue....and it's not really an issue. Just a code and no cycle.
