Ok, pulled the ECM tune and what in the Sam Houston did I just get myself into? Beginning to miss my Duramax and the old Suburban! I was not much of a gas tuner, I fiddled with a 2002 Suburban's 5.3 and hit a home run right off the bat with some chance guessing and changes, but this engine is a whole new animal. Any help you guys could offer or advice would be great.
So, here's what I'm looking to do with the wife's speedy grocery getter. I want to disable AFM, which I think I can do by just disabling it, am I correct? Then I want to try to increase its overall power a little, get it ready for a set of E fans and also setup another tune for all out fuel economy for when I go on vacation.
What kind of knowledge can you bestow on this ole diesel guy gone gasser?
AFM is disabled by replacing the valley cover with an AFM/DOD-delete valley cover (it seals off the solenoid spaces).
Can it be disabled in the tuning so it doesn't activate? I want to keep the hard parts for long drives, just disable it in town.
Post your tune file.
Crap, I'm on my phone too buddy. I did see a spot while playing half asleep last night in a DOD? Is that AFM? If so, it has a Enable/Disable section. If disable shuts it down, then I'm good to hook.
And I am trying to help the 2500HD guy track down the real issue, since those bigger trucks are my old forte, as a former admin at Dieselplace.
Post the tune file anyway, please, I want to take a closer look
