Good answer Mike. My only question is how can PPE remove defuel from their big tunes when it's the big power where you can have problems with no defuel? I don't know how they do it, but supposedly the excellerator can remove defuel from the ECM.
I build all my Alli's with extra protection against this.
Defuel is there to prevent a tie up on a shift under high power and high rpm conditions. The ugly truth is the Alli is not capable of shifting fast because of its design. You can take the defuel out without a problem to the Alli if you cut the power down. You must give the Alli enough time to make the clutch to clutch transition into the next gear or you will tie it up. A tie up is being in 2 gears at once for a split second or longer. Picture 500 hp and 900 lb tq in a 7K truck under WOT being in 2 gears at once for an instant. Guess what's going to give? I will award a cookie for the correct answer. :baby:
Okay so i just learned alot obout alot. 1 ? How come two different tunes will shift so differenty without ever changing the TCM. I have one tune that shifts firm threw every gear. Then the other will have you eaten your steering wheel every time it shifts and they are both about the same hp.
