Idle and surgeing issue

[SANDDEMON08]

Is there any updates on these issues. I have done everthing suggusted by Scott and still have no fix. I noticed i also have a little surging issues from 1,000 RPM to 1,500 RPM. This is also tired to weird fuel pressures bounceing from 4500 to 8699 PSI. I have also noticed a few fuel spikes to 30,000 when i hit it hard and let off quick on a hard pull. Truck seems to run fine when its cold in the morning until the fuel pressure ramps to 8699 at idle. Each time the truck is put in drive or when the ac cycles the idle issue starts.

Are the recent tunes you sent me the most current Scott?

Its odd, most the other people who had these issue's were getting codes throwin, i have had zero codes to date. I have that intercooler coming in soon and hope to put these little issues to bed before i install the cooler and have other possiable issues directed at the cooler that need to be addressed. Any info would be helpfull, thanks.

what tune is this happening on? I'm having the same issues but only on the 210 tune. I posted in the Tech Support Forum but have heard nothing from Matt or Scott.

[Goolsbymd]

Im getting the same thing around 1750ish RPM range while driving and if im idle at a stop light or sitting in the truck about every minute it will hiccup.

Running the 250 tune

I have the idle issue in all my tunes. The surging issue is only in the 150+ tunes.

[SANDDEMON08]

I have been leaving messages and send emails. The last corrospondance i have had with them was an email from scott on 7-22-08. In regard to these issues. I'm just conserned that when this issue started it only affected the idle, now im getting these other little gremlins and am gettin a little conserned about getting this fixed before i make any other changes or upgrades. I can only assume they havent found the fix yet which is way they have not responded. I'm sure its just a matter of time. I havent had any issue outside of these.

I checked for codes today i had one, actualy the first iv'e had, PO113 i guess it has to do with high air temp.

What air intake are you using? Have you gone over all the connections to ensure they are good and air leak free. The worse an unmetered air leak gets, the more issues the truck has. If it gets bad enough, the transmission will start to shift very erradic as well.

[SANDDEMON08]

Scott thanks for the reply,

First , i have the issue in all the new tunes 45-250.

I have the AFE stage II intake with the boost tube, nothing has changed since the last emails i sent you. I put sealent around all the fittings, the MAF,the restriction gauge and the crankcase vent hose as you suggusted and and let it dry overnight and no Fix. I unpluged the MAF sensor and the idle never changed, the rollin effect got a little faster and the cel light came on. I have checked all the fittings with heavy sprays of starting fluid and not one blip out of the engine while running. If theres that much air passing at idle, should'nt i be getting somthing. Even a small directly spray in the intake and the engine pick ups. Do i need to take the piping off and pressure test and check it with soapy water or what. There is no leak in this system between the air box and the turbo. If this problem being caused by an air leak why do i not have this problem in the morning when i first start the truck. On start up the fuel rail pressure is around 5,000. After around 7 minutes when the truck gets close to operating temp and the fuel rail pressure ramps to 8600 and the idle issues starts. Why is there no idle issue when the truck is in drive or the AC is on? I still dont understand why the previous 75HP and 150HP tunes spartan tunes i had gave me no problems and these newer 45-250 are giving me issue's.

At this point i dont care if its the intake, you tell me what setup works and i'll buy one to make theses issue's go away. I have enough invested now not to have a 200 or 300 dollar intake case me this many problems. I have stated this before, tell me what i need to do and i'll do it. So far the only fix you have recomended was the sealent which i tried and it did not work. Im open for suggestions and doing what ever i can to help resolve these issues i dont want to seem like a thorn in your back or a pest Scott, just let me know what i can do to get these issues addressed.

If you think it will help i can get the truck reflashed to the most current flash, i'v been waitingto do this as you posted at the diesel garage that it was not nessary.

Im having the the same issues but its really only on the 210 tune exactly how you described it. I have been running the 150 tune ever since that idiling issue on the 210 just because its annoying. Ive also notice it a little on the 150 tune when the truck is in park and i rev it up a ittle it will start idiling rough just like it did all the time on the 210 tune but as soon as i depress the brake it goes away.... I have also emailed matt/scott letting them know about this and they told me that i did have the most current updated tunes to fix this glitch but its still happening on mine....

Last email i got from scott was asking me if i was running the stock air box (which i am) and i asked if buying a cai would be my fix for this and he said that they are in the works of doing a cai shootout between different companies and was going to let me know which one to run when they are finished.... still not sure though whether that is going to be my fix or not though? Hopefully this can get worked out

i have the issue in all the new tunes 45-250

We onlly found the 210 file to make the idle issue more apparent. If this is happening in all the files, it points to a hardware issue, not a calibration issue.

I unpluged the MAF sensor and the idle never changed, the rollin effect got a little faster and the cel light came on

When it is electrically disconnected, the truck goes into a MAF default and should idle fine. Have you monitored fuel trims with the DD to see if possibly an injector(s) is going bad?

If this problem being caused by an air leak why do i not have this problem in the morning when i first start the truck

The trucks strategy is different at startup and doesn't rely on some sensor inputs until certain operating conditions are met.

Why is there no idle issue when the truck is in drive or the AC is on?

Doing either of the two adds load to the engine and smooths it out.

So far the only fix you have recomended was the sealent which i tried and it did not work.

This has cured many issues which is why I suggested that.

If you think it will help i can get the truck reflashed to the most current flash, i'v been waitingto do this as you posted at the diesel garage that it was not nessary.

I hoped the new files would help without going back to the dealer. I do know that a couple people did get the Ford reflash and they are happy with it.

It sounds like a EGR timing issue. The Ford Job 3 calibration update revamps the EGR opening timing at idle. Maybe a factory clibration update should be installed first. A aftermarket tune will only be as good as a the factory tables they are put on.

This is only the second item you have suggested in the past two weeks. How do i do this and I'll do it. What function do I monitor to get this info and what should I be looking for. Again im not trying to generate a issue with you on this, I will try whatever is suggested to resolve these issue's im having. If you think I need to take it to ford and have it checked out just tell me. If you think I should have it flashed just tell me. This is turning out to be more difficult then it needs to be. Just communicate a little with me and im sure we'll get this resolved.

I can get this done, i haven't yet because Scott orginally posted it was not nessary. I'm just waiting for his suggestions to resolve this.

[SANDDEMON08]

I checked the dash daq and found the fuel trim pips look like short term fuel trim for cylinders 1 thru 8 each has a pip. The pips have a $ sign by them and i can access them.

[Hanging_heels]

Nutty Professor, as you said above, i am only having this issue on the 210 file (a little on the 150 as i stated above but thats no big deal, its something i can live with) but what is the deal with the 210 tune why is it having this idle issue only on this tune? Is there any fix for it, or any fix for it on the works...? Thanks

[SANDDEMON08]

It took about 100 miles driving for the smaller tunes to act up on my truck.

[SANDDEMON08]

Scott, havent heard anything from you so this morning i took the truck to Ford and had them check the injectors. My Buddy spent 3 hrs doing numrous tests and driving the truck and could find nothing wrong with the injectors, the fuel system or anything else. So i had him flash it with the most current flash and I emailed you the new stratgey codes so you can update my tunes @ the 64calibrations email address. Please let me know if there is anything else i can check. Thanks Shane.

I sent you an email to the new files...

[SANDDEMON08]

I sent you an email to the new files...

Thanks for the quick responce Scott. Should have the new tunes loaded shortly and i'll let know how it worked out. Thanks.

[SANDDEMON08]

Looks like that did it no issues so far after 100 miles on the 210 tune. Idles great, no surging under power very refined compared to the prevoius stratgey and tuning. Ill start checking the other tunes after i get about 500 miles on this one. Thanks again Scott.

Sanddemon did you put your dpf back on when you brought it into the dealer or did you just set it ack to stock and rolled in with it straight piped and had them flash it?

I wonder if this is my problem because i am still running the stock air box with and when i run the 210 tune i stilll have that idiling problem... i really dont want to put my dpf back on and so forth just to bring it to the dealer for an updated flash....

A friend off mine works at ford and she flashed it in the parking lot.

Curbside service! Can't beat that!:)

[BigIslandBoy]

I wish I had a friend at the dealer like that! They were pissed when I came in with just an AFE intake. It will really suck to put it back to stock when it needs to go to the dealer.

[Hanging_heels]

So i got a email from Scott on friday with a new 210 tune file because of the annoying idle problem i was having and i have been running it since friday morning and theres no more rough idle issue for me whatsoever Before when i ran the old 210 file i had.... with in 5 mintues of me loading it, that rough idle would begin as soon as i started to slow down and while im stopped.

But anyways so far so good.... i love the power difference between the 150 and 210 tune but i wish there was more black smoke on the 210, the 150 definetly smokes alot more. Why is there not as much..?

Thanks to the guys at Spartan for working with me and getting this issue fixed. I'll tell you what, whenever i emailed these guys i would have a response back from them within 24 hours or less (usually less) and if it was something i needed to get a hold of them with right away i would give them a call and if they didnt answer i would have a call back with in a hour or so. Great customer service, i am completely and more satisified with this tuner and the guys at spartan.

[brad g]

can the dealer tell if your running custom tuner in the truck? i know that when you go back to the dealer i would flash it back to the original files but is there any way to see that the custom tune?

[texguy75]

Not sure if my truck is idling rough, but when I have the AC on it clicks on and off every 10 seconds. When I turn the AC off it stops, but I don't remember it engaging so often before the tune. Is that what you guys are talking about?

That is normal.

[hotlicks2go]

Sounds normal... although keep in mind that if the refrigerant charge is slightly low, as it runs, the low pressure switch will shut off the compressor. As soon as the static pressure then starts to rise, the clutch will engage and restart the compressor. Not sure if this pertains to you, but keep an eye on it.;)

Can I monitor the refrigerant charge with the DD?

[hotlicks2go]

NO but possibly the a/c clutch engagement, (when the compressor comes on/off) but I'm not sure.

A/C compressor request is an enhanced Ford pid.
