FICM mileage

International350 · #1 Thu, May 6th, 2010, 10:38 PM

I just got PHP FICM programing and all runs great, only thing is i didnt get anything for MPG. Im still getting the same 11MPG ive been getting. I had Innovatives ficm programing before and also didnt have any increase. What am i missing? I do have a SCT with one custom tune from ID its a mild street tune. Though i can put it into stock and still get no increase. Is there some tuning to the PCM or another tune that i can use? I do like the occasional stop light race so i dont want to go backwards in power if possible.

Also i was looking into PHP extreme tune and wondering how drivable this tune is? Does it lock each gear until 3K rpms or is it more drivable? Also is it 140hp over stock? Thanks

I second this. I had mine done back in January. I wanted to wait until the "winter fuel" was all used up to see if the MPG improved, but it hasn't. Any suggestions?

PS, there is nothing wrong with the FICM Programming, just wasn't what I expected I would see on the gains side...

Yeah the FICM works great, the mileage is the only downfall. I just want to see if there is something else that we need to check on our trucks that are killing mileage, like on gas motors if the O2 sensor or maf sensor, or spark plugs is bad your mileage drops. Is there something our trucks have that should be looked at.

I think the people that see the increase in mpg are people who had the latest ford flashes with the I.H. strategy. They noticed the mpg go down when they were flashed, and wanted it back. If your truck was never flashed with a I.H. flash they you probably won't see a difference. Perhaps the PCM needs to be returned to an original program as well?

Mine were, and I noticed it went down, the PHP ficm brought it back to where it was originally.

That may not always be the case. IMHO 11 mpg is pretty poor for your truck, I doesn't look like you have much of a lift or larger tires in your picture. So i at a loss as to why it so poor.

Yeah my truck only has a level kit on it, and tires are just 33s. I use to see 17mpg back in the day, but that was before 3 trips to Ford so Im sure i lost some somewhere. Im waiting for a custom program to come back from you guys to download with my SCT, if im understanding right that is the PCM tune right? Hopefully that will bring it up.

What I meant with PCM programming was to return the truck to the Original ECM and TCM program files, to do that you would have to ship your PCM to Bill for reprogramming.

Now I'm not Bill nor do I share an ounce of his knowledge, so getting a SCT program from him may do the trick, I don't know. If it doesn’t you may want to try getting everything returned to the factory programming and then getting SCT programs for that Strategy. Though I can't imagine there is something in the origional programs that a tuner cannot correct with the SCT/Gryphon, to get the issue resolved.

Perhaps Bill will comment on this at some point.
