FICM mileage

[Jeremy]

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.

Yeah when i talked to him I did ask if the custom tunes on the SCT covers all the parameters on the ECM and he said yes if i understood him correctly, that when you put your tune on it should do the trick. Ill prob have my tune in monday or tuesday from him so i can check it out for sure. I appreciate all the help.

so how long have you been waiting for tunes from php?

[International350]

I just sent out the request this past firday, so only couple days. You been waiting a while? They had my FICM back to me in 5 days.

[sonic blue l]

over 2 months and still nothing.

sorry not tring to hi-jack, just was curious about the wait time others were experienceing.

A guy at work, whom i told about php ordered then same time as i. His chip/burner and tunes only took a couple weeks, but that was also for a 7.3 so perhaps that was the difference.
