fuel economy tunes

[brad g]

Spartan i was wondering if your planning on making any fuel economy tunes?
i travel alot with my truck across canada for work, and i notice that when i use the higher horse tunes (310) i get way better milage, but i cant run them in town because of the blackout effects of my exhaust and the facts that the cops dont like it that much, and the touchy throttle , well lets just say i have to clean the back seat every day cause the kids spill everything when im running the 310 lol .. i detune to the 210 when driving in town. i dont need the neck breaking acceleration, touchy throttle and super hard shifting i just want the fuel economy and power on the highway when im lock up for cruiseing at 1800rpm and 120km. Is there any way to make a tune that is derated untill the truck hits highway speed? like for example the power and nice shifting of the 210 for normal driving around town, but then once the truck hits lock up the power goes up to the 310? you have strictly race tunes, can you make us a daily driver non towing tune?

this should be easy for you guys ...

[Longhaultransportation]

These are Off-Road tunes only. ;)

No need for fuel mileage Off-Road....right?

[64forsure]

These are Off-Road tunes only. ;)

No need for fuel mileage Off-Road....right?

Exactly, lets call it the "off-road MPG test tune" ;)

[08stroker250]

If you guys want to PAY for a tune from Matt, then I am sure he will be willing to play around with my truck on making a tune. I am going there next week to get my Suncoast put in. I'll see what he says. We will not be able to release a fuel economy tune though.

[alirette]

I am willing to pay for a fuel economy tune, it would be graeat if a few of us can split the development cost, and have access to the tune.

[kylebryan]

Hell yeah ill pay for it too!

[64forsure]

I would too!

[Longhaultransportation]

DPF/CAT Delete with EGR Off and MAX Fuel mileage would be a great tune.

I'll buy one.

[08stroker250]

I'll see what I can do while I am there this week. No guaruntees though fellas. Matt takes his time on this stuff, and since he has the 6.7 tuning to work on, it could be awhile. Its worth a shot though.

[kylebryan]

thanks Jeff! Itll be cool to see what kind of mileage numbers they can get out of these 6.4's

[64forsure]

This would be great! I want the tune so I can test it on the track to see what the 6.4 is capable of MPG wise :D

[kylebryan]

yeah same here "on the track" hahaha

[03SVTCOBRA]

I'm in for that tune as well....

[64forsure]

There is definitely some wide interest in a tune it seems. Please let us know what you find out Jeff, and thanks.

[Nova606]

I am also in for this tune.. I would like to something in the 20s for MPG

[gettinmyrocksoff]

Count me in also, with milder shifting also

[08stroker250]

So the current count is 8 that want this. Pretty decent amount of interest.

[64forsure]

I think if word got out, that number would climb significantly to far more than 8!

[08stroker250]

Word doesn't need to get out though. Remember the policy on this.

[64forsure]

Word doesn't need to get out though. Remember the policy on this.

No problem, I definitely understand.

[alirette]

Their is a matathon race at a local track here, and the concept is only 3/4 ton trucks can enter, and it is a race to see who can finish first and who runs out diesel or gas last. this fuel saver tune will be a great tune option for that racing application.

[BigKid]

So the current count is 8 that want this. Pretty decent amount of interest.

I think it would be a nice tune to have. Perfect for certain applications.

[Nova606]

I concur!!!! I think for "certain" applications this would be great!!!:D

[brad g]

So what were looking for is an OFF ROAD tune That has 275 -310 power for cruising at highway speed , smooth acceleration and shifting like the original 210, and something that wont black out the "back roads" when you first take off. Matt i know you derate the engine power until the truck is at operating temps, can you derate the truck and have say the power of the 150 untill say 40mph? then once lock up the power goes up so we get maximum milage while crusing? i just did a 2700 km all hiway trip across canada running 310 tune , i drove straight threw and didnt shut the truck off once, the trip took 26 hours and after the frist top off i only used 3 and 3/4 tanks of fuel my lie o meter said i was getting 9L /100 km this wasnt to far off the furthest i drove on one tank was 835 km and it said i had 2 km to go... till empty... lol
I know these trucks are pigs on fuel for daily driving but once in lock up and on a long haul there great. I am Looking for an OFF ROAD Tune that will help with this. ANYONE ELSE looking for an OFF ROAD TUNE LIKE THIS SPEEK UP. If we can get enough intrest maybee spartan can look into this as a side project for us... If we get enough people intrested we can split the cost on development for such a tune,


I dont need a race tune, I need the fuel economy :)

thanks
Brad Goliboski

[dlguns]

I will be waiting for this:)

[08stroker250]

Don't get your hopes up guys. It is up in the air right now. There is a lot of interest, but it will take me forcing Matt to do it lol. I will see if he wants to do some testing on my truck and then we will go from there.

[brad g]

Maybe KEM performance will look into the economy tune as well ? nuttty you up for the challenge? :D

[Ipkyss]

count me in

[Cody M]

I'm in as well for the tune, if it gets made.

[Superstrength08]

I don't think it would be bad to create a fuel efficiency tune.

[svtbolt2001]

It looks like these guys are the only ones offereing a true DPF delete for fuel economy.
http://www.rivercitydiesel.com/37701.html

Now do they get better MPG than us? No idea.

[64Diesel]

Count me in too. I think it's a great idea.

[64forsure]

I just want to point out something. I think it is hilarious that we live in a time were we have to be secretive about getting better fuel economy :rolleyes:

Doubtful.....

[BigRedDually]

Count me in on an economy tune as well.

[abitz]

count me in too :)

[Dash2008]

I am interested in the mpg tune also as I currently run the 250 delete tune at present.

DaSh

[brad g]

Jeff did you talk to Matt about this tune? any news ?

[08stroker250]

Jeff did you talk to Matt about this tune? any news ?

No, haven't had the chance to talk to him yet. When I went up Thursday night it was all tranny, not much room for chit chat.

[rodo]

I am all about offroad mpgs...count me in.

[mick1955]

Guys, don't count on this happening any time soon if it does happen at all. This subject has been discussed in the past. I don't think you will find anyone out there that wouldn't like an economy tune. It's something that will involve a lot of time and money.

Matt is currently working on tunes for the 6.7L as well as everyone else that makes tunes for these trucks. It's a big project that involves a lot of time just like it did when the 6.4L came out.

For those that have never seen what's involved in creating a tune and going through all the testing you would not believe all the hours that it takes. Not only in just creating the basic tune itself, but then all the hours in making different adjustments, then testing it on the truck, readjusting, testing and it goes on and on and on. It just a long drawn out process.

Hopefully, he will have time later on to see what can do in this area. Don't give up on us. He's always up to a challenge......

[JetFuelOnly]

I am interested in this too:

Priorities:
1. MPG (around town as well as highway)
2. Softer Shifts (softer than the 250 tune, more like the current 175)
3. Power (Better than stock, but doesn't have to be a race tune)

And it has to be reasonably clean.

I think there is :eek:HUGE:eek: interest in this type of a tune.

[64power]

MPG is why I bought my spartan setup - so far it's getting around 3 mpg better than stock running the 275 tune. I would love a MPG tune that has the safety parameters of the lower HP tunes. Since I live in SC I'm not concerned ATM about how much smoke it blows - I simply want more MPG while not having to worry about blowing something out.

NOTE after running the 275 tune through 6-8 tanks of fuel I don't watch my DashDAQ like a madman anymore so I really don't know what safety features I'm missing.

I think other than the safety parameters back into the 275 a less sensitive pedal would be nice when I'm going off road. It's VERY difficult to ease yourself around rough off road situations with the 275.

Oh I would also be willing to pay for this tune as well.

[64forsure]

There are many of us who bought our Spartan systems for better MPG's. I get a little better than stock, and my truck definitely runs awesome. It would just be nice if there was a low power tune, that at the same time gives better MPG's. I don't care if it runs like a snail. If I can take it on long trips, and get 20MPG all the time, that would be great! I am definitely willing to contribute to the developmental process.

[Dash2008]

I would like to find out who else can do the programming. Everyone is all tied up with the new 6.7, so where else can we go to have the programming done.

Your not going to see anything change with the current 275 tune. It is designed as a competition tune and that is what it will stay. I have managed to get good fuel mileage with it, 19.7 hand calculated with the most recent one on 35" tires. It can be done, you just gotta get it in the right RPM range. Usually on a F-250 with 3.73 gears its that 1800 RPM range around 65-70 mph.

DaSh

With your DashDAQ....only Spartan and KEM Performance can write tunes. You would have to buy a different tuner for other tunes.

[bkuepaint]

Count me in. It would be great to have the power and get someting in the 20mpg's.

[08stroker250]

Like I said before, if you guys can learn to keep your foot out of it with the big tunes, you will see pretty dang good fuel mileage. The 275 tune in the 1800 RPM range on the highway will yield some really great results. A guy over on Powerstroke.org just reported 17.6 mpg highway hand calculated on a highway trip from Minnesota to Michigan. That is impressive in my opinion. Not to mention he is moving a lot more fuel than most of us. He has a Floor It Diesel modified HPFP that is moving a whole lot of fuel.

Well I really wasn't trying to ask for a new 275 tune - just adding my voice to the MPG tune - Was simply giving examples.
I'm not sure if I would get 19.7 mpg but I'm sure if I was all interstate miles my MPG would go up - I'm in the 1800 range in the 65-70 mph when I'm on the interstate but I have to drive about 7 miles city then 20 miles interstate twice a day with an additional every other day 13 mile trip that has about 6 full vehicle stops.

My observation is that anytime I have to stop - that is where I am loosing fuel efficiency - it's taking a lot of fuel to move the 8k+ pounds to speed.

I'm not sure when I accelerate if I should give it higher RPM's to get to speed quicker or if I should accelerate gradually for longer. Talking about maximizing MPG of course. Any feedback would be great on this question!

[Longhaultransportation]

The tune I want would not require more power. Heck, you could take some out if needed.

99.9% of the time I am either pulling a trailer or hauling my camper in the bed.

What I need is a tune that will maximize the life of this engine and get better fuel mileage as a bonus.

1. EGR OFF. I don't want all that soot getting in the engine.
2. DPF OFF. I don't want to waste all that extra fuel, plus add fuel to the oil.
3. FUEL MILEAGE. With my 4:30 gears, I turn 2000 rpm about 60 MPH and get 9 MPG. Anything better than that would be a great bonus.

The 210 tune does 2 of those things, but it didn't help my fuel mileage at all and it smokes too much. I don't want to run high horsepower smoke tunes.

This is what I want.

Your needs may be different. :cool:

[Dash2008]

It would be interesting to run a poll for a couple weeks to see what kind numbers come in.

DaSh

[08stroker250]

Poll is up

[rrose]

I would kill for a fuel mileage tune..... thats all I ever wanted in the first place. I don't care how much horsepower it makes...... I just want to get better fuel econonmy. I'll pay for it, no problem!

[JetFuelOnly]

I hear all kinds of wild stories about MPG. I just can't believe it anymore.

I have a 09 F250 Crew Cab Standard Bed 4x4, 6700miles (yeah its pretty new).
I've had the Spartan tunes on it since about 500 miles.
Normal running weight is about 8k lbs (Shell, liner, bedslide, some cargo, me)
3.73 gears, 34" tires.
Mixed driving, about half and half.
No DPF, No CAT, 250 Tune and my last tank of fuel hand calced ~13.2 mpg. (I was real careful to fill till I saw the fuel in the filler tube each time)
I have managed to get as high as 15 mpg almost entirely highway driving and an average of 9 mpg towing a 15k lb trailer. (got down to 7mpg with some nasty wind)

Is this as good as the mileage is gonna get?

My last truck was identical design, except it was a Chevy Duramax from 2004. I averaged 17mpg in mixed, 18 highway, and a low mixed with AC on and lots of city for 15mpg. Yeah no cat, banks kit, exhaust brake. Recently sold it and the buyer is getting the same mileage (they were ecstatic as they were coming from gas)

[kylebryan]

Same here. I love the horsepower but thats just a tune change away! lol I think if the cost were reasonable it would be worth the money to pick one up. hope the poll comes out in our favor lol.

[08stroker250]

I made a 200 mile highway trip yesterday on less than half of a tank running 1900-2200 RPM's with the 275 tune. I probably should have filled up after the trip to see how good the fuel mileage was....but I am assuming it was in the 17-18 mpg range. If I had stayed 2,000 RPM and lower the whole time it would have been even better I think.

[kylebryan]

is that too much to ask?

[08stroker250]

Only by about 25-30 mpg lol

Go buy a Jetta TDI if you want a diesel and that good of fuel mileage!

[kylebryan]

Can spartan tune me a Jetta if i get one haha

[08stroker250]

Mike (Nutty Professor) can do custom tuning onsite with VW and Audi vehicles I believe. I am sure its just laptop tuning.

NOTE - when I say onsite, I mean at his location in FL (KEM Performance)

Question for those who have voted "I don't care either way"....

Are you voting saying you don't care if you have a fuel economy tune or not?

[03SVTCOBRA]

No, I was voting that I don't care if is cheap or expensive, I gotta have the tune!

[R-T0r21on]

Question for those who have voted "I don't care either way"....

Are you voting saying you don't care if you have a fuel economy tune or not?

I really don't care either way. I don't think there is any value to a tune for "economy" only. If you can have good MPG's and good power too, then why bother? It would have to be 25-30 MGP to be worth the trouble. Also, it would have to be EPA compliant. I think we all know we're not going to be EPA compliant AND get great MPG's. Just ain't happenin'.....

It doesn't have to EPA if it's Off Road Economy.

I don't want more power. The stock as delivered from Ford power is fine.

I want No Smoke, No DPF, NO EGR, and better mileage.

As I said before, others needs may be different.

[08stroker250]

Well.....individual needs aren't going to be an option, just considerations for the tune. If this does happen, and that is a BIG HUGE IF, it will most likely be a widespread tune that will be labeled as an offroad tune that can be downloaded from the website with the other tuning files.

[R-T0r21on]

The implied intent would have to be for "on road" use, AKA EPA compliant. Who cares if you get great MPG's pulling a sled, or running a quarter mile race? Don't get me wrong, my truck is my daily driver and not EPA compliant anymore. I really enjoy the power & improved MPG's. I just don't think anyone can make these trucks get good MPG's "on road". They're big, heavy trucks designed to work hard and do it within certain EPA guide lines.
Lastly, I was just trying to fully answer the question posed by 08stroker250.

[Redram99]

I would love an economy tune.

[64forsure]

I would love to have a low power "economy" tune for the long, boring unloaded drives. One that shifts really smooth, and is more of a "comfortable" tune over a "powerful" tune. Like I said before, I would rather my truck have less power, and get better MPG most of the time anyways. Of course, I don't make the tunes, nor do I know how. I am sure it is very involved, and has all sorts of strings attached in getting it created.

[08stroker250]

Lower power economy tunes aren't likely.....these trucks tend to get better fuel mileage with the higher tunes. The big thing that hurts us is RPM....and for those of you with 4.10's and higher, getting great mileage just isn't possible. These are 8,000+ lb trucks, and the lower the gears, the worst mileage your going to get. Really and truly, if you don't have 3.73 or 3.55 gears in your truck, 20 mpg is not achievable no matter what.

You should start a thread in the 6.7 section and post this article up.

http://www.spartandieseltech.com/forum/forumdisplay.php?f=25

[64power]

Wow if the '11 6.7 is getting that great of mileage I just may have to trade my 08 in for one - once the reliability has been proven.

[03SVTCOBRA]

Is that mileage for real on the 2011 trucks?

[08stroker250]

Some guy did a cross country trip in one....not sure if thats what is in that article or not (didn't look lol), but he got like 21-22 mpg on a 2,500 mile trip or something along those lines. Pretty impressive in stock form with all the emissions bullshit on the truck. Just imagine what getting rid of regeneration could do for it.

You also have to remember the new trucks are geared much higher. I think the lowest gear set you can get is 3.55 or 3.73 on the new trucks. Matt's new F-350 has 3.55 gears in it. It runs at such a low RPM around town....awesome for fuel mileage and top end speed, but sucks for towing heavy loads lol

[kylebryan]

I cant wait to see what spartan does with it!!! the mileage gains would almost offset the increased payment of the truck. Jeff, When are you getting a 2011?

[08stroker250]

[64forsure]

When I can put an 08 front clip on one :D

I definitely agree with you on this! I think the 08 front clip looks far better than the 11's. I'm not sure it will grow on me like the 08's did either. They don't look terrible or anything, it is just a little overkill I think. The 08's front clip is big enough as it is!

[kylebryan]

Alright so we have 27 people right now that have voted that they would pay for an off road fuel economy tune. I hate to throw numbers out there but that would be a pretty decent little christmas bonus for mick or nutty lol!

Well, maybe Mick....not Nutty. He writes his own tunes through KEM Performance with our tuner. Nutty ain't on the Spartan payroll, never has been actually.

Are you voting saying you don't care if you have a fuel economy tune or not?


My vote of "I don't care either way" is that I don't care if I have a fuel economy tune or not. I knew when I bought a 3/4 ton 4X4 truck that fuel economy was not going to be one of its great features (c'mon, it weighs 8,000 lbs). Besides, I'm getting MUCH better mileage on my 6.4 F-250 than I get on my 5.4 gas F-150 company truck. The F-150 usually averages around 13 - 15 mpg, while my F-250 gets anywhere from 14 - 19 mpg (depending upon how heavy my right foot gets). And, my F-250 would outrun my F-150 even if it was towing another F-150.:D

You cant honestly say that you wouldnt like better mileage! I agree these trucks get respectable mileage for an 8000lbs truck but any chance i get to save a few $$ at the pump im gonna take! Now, on the other hand if the tune came out and cost 300$ it wouldnt be worth it to me. I love the power of this truck and everythign but im a realist and have to say that im always going to want better mileage no matter what.

[Longhaultransportation]

If I could get 15mpg without a high horsepower tune, my life would be complete.

I know guys who run gas F-250's and they're getting 8 - 9 mpg, EMPTY, so I can honestly say that I am happy with my truck's mileage and just don't expect anything greater. I have to admit that I was a little disappointed in my mpg before adding the Spartan....when new, I could get 17 mpg on an interstate trip, but my truck had the injector o-ring recall and while I was having that done, the dealer reflashed my truck and it never got over 14 mpg after that. But, now that it's tuned, mpg's are back where they should be, and I have MUCH more power to boot.

There is one for $300 that will improve your fuel mileage :D

That won't happen man....these trucks respond the best to higher horsepower tunes when it comes to fuel mileage. The higher tuned the engine is the less effort it takes to get up to speed. Hopefully that makes sense.

My vote of "I don't care either way" is that I don't care if I have a fuel economy tune or not. I knew when I bought a 3/4 ton 4X4 truck that fuel economy was not going to be one of its great features (c'mon, it weighs 8,000 lbs). Besides, I'm getting MUCH better mileage on my 6.4 F-250 than I get on my 5.4 gas F-150 company truck. The F-150 usually averages around 13 - 15 mpg, while my F-250 gets anywhere from 14 - 19 mpg (depending upon how heavy my right foot gets). And, my F-250 would outrun my F-150 even if it was towing another F-150.:D

Exactly what I was thinking. This thing still gets better mileage than my 6.0 and 7.3...and that was when my 6.4 was stock. More mileage and power...what else is there. Hell I can go at least 1000 miles on a fill up anyway.:cool:

WHAT? At best - I MIGHT get 600-650 all interstate IF I ran it dry (38 gallon tank)

Yeah, I have a 90 gallon external tank and go over 1000 miles as well.

What does that have to do with getting better fuel mileage? :confused:

[OOWeaver68]

I know it has nothing to do with mileage, I was just joking around.

Bah - got me...

OK, So high horsepower is needed for fuel economy.

How long will this motor last with the 275/310 tune, pulling 16,000 lbs. or hauling 5,000 lbs in the bed and pulling 10,000 lbs trailer?

I need this motor to last at least 250,000 miles. I believe it will last that long easily with stock power, no EGR and no DPF. Not sure with the high horsepower tunes.

Any thoughts?

It can be done with high HP tunes but you have to be very carefull and watch your temps. It's not recommended. For the heavy work, I'd get the 210HP tune or the new 210HP Tow tune.

I have the 210 tunes, but they don't increase my fuel mileage, at all. Plus, there is a lot of soot on the side of my trailer/camper. The power is nice, but I don't really need it.

I'm interested in an economy tune, as well. Also, I may be mistaken, but I'm yet to see any of the 2010 F250 4x4's with 3.55's report their mileage with tunes. I am curious if a gear change from a 3.73 to a 3.55 and tuning would further help MPG. The same goes for a gear vendor and tuning. Sure, changing those kind of parts would be costly, but how great would the gains be (for curiousity's sake)? If the gear vendor drops engine RPM down 500RPM at cruise, that would put me at 1400RPM at 70mph. Stock, the engine would more than likely labor at that speed/RPM combination due to the extra wind drag and lower power. Would a tune or custom tune help this situation any?

I have been thinking about the topic of fuel economy for a while and would love some feedback on a few food-for-thought type questions. What factors need to be maximized at cruise to create better fuel economy? In general - fuel rail pressure, injector timing, injector pulse width, and actuator position/vane position... ?? Is it possble to lean the engine out (at cruise), just enough so that fuel consumption is at a minimum, but enough power is still generated to pull the truck's own weight through wind resistance??

I can't guarantee that this is going to happen guys. I am going to close this thread for now until I can say anything for sure.
