Be my guest.
So far, people who have tried the 58v mod have pretty mixed results -- ranging from no difference to codes --- separating the ones who just did the voltage and not additional software tuning.
I like my chassis mounted FICM just fine.
It is orders of magnitude more reliable than the engine mounted part.
Oh... yes... I have a standing request for Ford to come up with a derated tune for the 6.7 so I can get more life out of that motor!
If there is a way for me to do a programmed cylinder de-activation to get more fuel economy (technically possible with a newly designed and programmed FICM), I would do that too!
Right now, the back-of-the envelope economy gain from a programmed cylinder deactivation with 4-6-8 arrangement is yielding about a 10 to 15% estimated fuel savings --- nearly worthwhile to try.
I am optimizing for longevity and fuel economy.
Ford didnt seem to mind makin a million test trucks, than they did it again with the 6.4, o and whats next, a couple more test subjects with the 6.7! I dont understand why you hate all aftermarket parts? You berated Bulletproof Diesel forever, Than 1 day you recommended them (I am aware he answered some ?'s)
! I think the ford ficm is a problem, so I would rather replace with an "upgraded" one, versus a known to be garbage one! Maybe just Maybe it is infact better!
Would you like me to email them with all your questions? Or maybe send them this link?
