It is a great price at 287.00 and I am only looking for better mileage and towing performance. i do not care about the 1/4 mile and everything else. Just a mileage upgrade and towing performance.

 

i am wondering the same thing! found one on craigslist thats unlocked for 70 bucks. i wouldnt mind getting it but i cant find any feedback on if people like it or not

 

I have the Mileage XS tune in my SC FP 1865 tuner, I get better mileage and power with the 87 octane perf tune just as the folks at Troyer's said it would.

The Mileage XS tune might help a lighter vehicle at lower speeds on Kansas roads. Stock tune was much better than the Mileage XS when used on my '07 FX4.

Not sure what tune options are availabkle with the tuner you are inquiring about.

 

thanks a lot. that definitely kept me from wasting 70 bucks. if i am just trying to make up for a little power loss (from bigger tires) and maybe get 1 mpg better which programmer do you recommend? not looking for anything fancy or too expensive. just something where i will notice a difference. thanks

 

Please DO NOT buy ANY programmer/tuner for MPG improvements. You will likely be disappointed.

Your best bet (and it's only a 10-20% chance IMHO) is a Gryphon or an SCT and custom tunes.

 

x2!

 

First off, I agree .... DO NOT BUY a tuner thinking that you will for sure see a mileage increase.

Having said that however, I got my FP 1865 for some slight improvement in power and better shifting I hoped. With it, I got better power, noticeably better response, better shifting with less hunting and in my truck using the 87 octane perf tune .... and I experienced an increase in gas mileage.

I had purchased my 2007 FX4 with 5.4 and 3.55 gears in August 2009. It had a cat back exhsuat with SI/DO muffler already. It also has a different intake tube, someone's store bought version of what is known here as a "Gott's Mod". Air filter and housing remain stock.

I checked my mileage every tank, both locally and during a 1100 mile round trip to see wife's family in Ga. With a featherweight foot, doing my best to stretch a gallon, the truck's best highway mileage was meassured several times at 18.5 mpg. I'm sure I still have the gas tickets in that box, all BP regular, I enjoy my 5% kickback.

In Feb 2010 I decided to contact Troyer's, the shop is 40 miles away. I expected to be steered towards a custom tune set up. Instead, after listening to what I wanted, I was steered to the Superchips Flashpaq 1865. They told me about the various tunes and they told me the included Mleage XS tune usually did not resultr in better gas mileage with a truck. They did tell me that many customers got an increase with the 87 tune however, but no guarantees.

I bought the FP for the power / response / and shifting.

Response wa noticeably better as soon as I dropped the truck in gear to leave. Shifting better,, both quicker and firmer and no more hunting or flareups. Truck feels like it has better power, certainly no harm, I was a "happy camper".

What I found in use though was what seemed like a gas mileage boost. In checking later tanks, I saw a couple tanks on longer non stop runs approaching a calculated 20 mpg. It NEVER did that stock.

In June 2010 I took a trip to Indianapolis to get a home AC and visit an old buddy and for the road trip. I had a Scan Gage II hooked up (got in March 2010, it reads many many inputs and using road speed and GPH, it gives instant MPG and since it knows time and speed, it also updates AVG MPG if you choose that gage, I have found it to be very very close to calculated figures {miles devided by gallons used equals MPG} ...when using the AVG MPG numbers on a non stop run, stops "reset" the calculations which is why I say "non stop run".) I use the instant MPG gage like an old vacume gage to monitor my foot better as it shows instantly the effect your foot pressure has. (Before SGII, I often used a simple vacume gage to monitor manifold vacume as I drove, been doing it off and on for many years, good for self training)

I retuned the truck using the Mileage XS tune, mileage dropped and I had to use more throttle to maintain speed on all but down grades. After a couple hundred miles, I was ready for coffee and a biscuit and to dump the Mileage XS tune, so I stopped. Gassed up, figured mileage (under 16 mpg, easily worse than even stock) and retuned it with 87 Perf tune while sipping coffee and eating my biscuit and while wife walked the dog.

Next 200 plus mile tank was over 19.5 mpg and that was still running some in West Va. and Ohio hills. On a third tank that saw me on flat Interstate, she broke 20 (I do the calculations just about every fillup on the trike, bike, car, opr truck as a habit).

This past January, our regular trip to Ga., same truck as Jan '10, same load, same roads, same old plugs (under 35K), but with the FP 1865 where I was seeing my fill up calculations topping out at 18-18.5 in Jan '10, I saw high 19 - 20 plus a hair mpg in '11.

Folks can say what they want, believe what they will, but I've been calculating fuel mileage since I was a young boy doing it in my head with the numbers my dad read off at fill ups (and I was almost always exactly right with his numbers ... but I have always been good with math that way) back in the early '60s and there's no question about it ...
... the FP 1865 on the 87 Performance tune in my 2007 FX4 scab 5.4 w/3.55s lead to a solid 1.5 mpg (best ever seen was 20.4 calculated all flat roads Indianapolis to Lisbon, Ohio) increase in fuel mileage. (I only claim 1.5 because I never drove it stock on that one road where I saw the 20.4)

No guarantees!

I never have used the 91-93 octane tunes as I don't care to pay the fuel costs for minimal imcreases. I don't need the heavy tow up to max tow rating, the 87 Perf tune allows up to 6,000 pound tow weight which covers my uses.

 

I have a FlashPaq 1815 (old version, replaced with 1865) that has the MileageXS tune on it. I used the MileageXS tune for 2 tanks and dumped it because I get better overall results with the 87 octane Performance tune.

 

Despite many peoples claims to the contrary here, many of our customers experience MPG improvements from the installation of our canned tunes.

There is never a guarantee, as driving style will play the single biggest role in your actual mileage, but a better running, more efficient engine will generally show an improvement in mileage. If you are using less throttle input to accelerate at the same rate you did with the stock tune, or less throttle to hold steady speed on the highway due to increased torque output, you will see an improvement.

Thanks

 

Only if less throttle really means less fuel (and not simply eliminating the DBW lag) and the AFR is actually closer to stoich. Reducing the DBW lag won't do squat for MPG.

I would like to hear how any programmer is going to 'make a better running engine'.

There is one statement that is absolutely true with a slight caveat, driving style and good maintenance will play the biggest roles in your actual mileage.

 

I ran my canned 1715 tuner for over 100K miles on my 01 Screw 5.4 and I got better mileage and the truck drove better, ran better. My opinion is that it was primarily due to the transmission program improvements. A custom tune would have given me more performance but I was very happy with the 1715 over stock.

 

Better efficiency be my guess.

Different ignition lead curve, different fuel curve, same ways that they make more HP and Tq.

The tuning is intended to help with power and response, more power and faster - more positive response means shallower stabs at the throttle to maintain speed in cruise mode.

Better mileage is just a benifit noted by some under the right conditions, and using all that new found power all the time will not reveal it.

True, they don't heal worn rings or burnt valves or worn bearings or slack timing chains or broken valve springs.

 

Mileage is a real gamble. Until recently I had been running my PHP Custom 87 Performance tune around town and was averaging 13.3 with nothing but stop and go and short drives. This was the same mileage as stock but with significantly better performance. Recently I ordered another custom tune. This one was based off of a tow tune with a few other things I had specifically asked for. My mileage has jumped to the mid 15s. A portion of that was the 20-50 degree drop we suddenly had. Before the drop I was still seeing high 14s.

Here's why:

1. I asked for a tow based tune so torque was the primary objective. I have a 4.6L, slightly larger than my stock tires and a 3.55ls so mechanical ratios are not on my side for stop and go traffic. Being able to generate torque sooner gets the truck moving easier without making the RPMs jump up. This why canned tow tunes work well as every day driver tunes.

2. Knowing the gas pedal is DBW and sensor position based I asked to have the lower end of the pedal position "sensitivity" reduced. I got a tape measure out and figured actual distances, percentages, etc. and made it very lethargic, even below what a stock vehicle has. My primary goal here was to form a pedal buffer for when I'm bouncing around rough ground. I had tried to stiffen the pedal but it didn't work, this was the next alternative. When not on rough ground, however, this gives more precise throttle control in low input situations (cruising). In regular english I guess that means between 0 and 10% throttle input I have stretched to 25% pedal travel. It also makes a good tune for new drivers or when backing up and such because the vehicle is less responsive and steadier.
***Most people would absolutely hate this tune because it tricks you into thinking your performance has been taken away. This is why PHP stopped offering mileage tunes. People would order them and then complain how it was as bad if not worse than stock. Much of the time they also saw a drop in mileage because they expected the tune to magically make things better so they drove the same if not worse.

These two traits only enhance the most important point.

3. I want to spend as little as possible so I drive smart. I've tested out what kind of accelerations up to speed have the most efficient use of power and what cruising speeds give the best mileage based on road conditions. I really don't go above 60 unless I need to. This among other things like parking in the middle of a shopping center and walking the loop to get what I need instead of cranking the truck just to drive to a different parking spot has helped lower fuel consumption.

4. Only bad part about the tune is higher speed traveling starts to use fuel faster. With this tune my highway mileage never officially gets above 18. My performance tune gets that running 70+ on rough surface county back roads. IMO if you are dead set gambling for mileage, don't put your eggs in one basket and hope for an improvment. Experiment with different things, keep track of what works and what doesn't. Then you can distill that information to get the best that the vehicle can. I didn't figure all this out in a day or week. I've been trying different things ever since I got the truck over two years ago.


Also, for people with programmers with Avg mpg displays, it is a waste of a position so don't even look at it. Put something more useful like engine temp and rely on your pencil and paper math.


Pretty much.

 

Its obvious there are no tuners here

Optimizing spark is the best way to find part throttle/cruise mileage. You missed that AFR is always stoich at part throttle, cant get it any closer.

I find it hard to believe that you can't imagine an engine running better after its tune has been optimized....

 

But what if the factory tune is already REALLY good with spark adavance, fuel maps, etc.?

For my 09:

Mileage before custom tune
Miles: 17663.0
Gallons Used 1015.37
MPG: 17.40, but this includes over 3000 miles of towing (averaging 14-15.8 MPG). Therefore 'net' MPG is 18.13 MPG

Mileage after custom tune
Miles: 14446.3
Gallons Used 793.4
MPG: 18.21

Total increase = .08 MPG.

But as I have stated many times before, that's NOT why I bought the tuner and custom tunes and as I stated above, if you do you will likely be pissed.
