It seems like it is hitting some type of rev/speed or torque limiter ,whether or not you start the pull at 2000 3000 4000 or whatever it will always only make it "ABOUT" 1300-1600 rpm before it hits a brick wall. I have tried it leaner ,richer more timing less timing etc and it seems that no matter what it acts the exact same.
I have maxed out all of the TCS tables, speed limiters, Rpm limiters and any torque tables I thought could affect things.....
I noticed looking at a LSX 454 file in HPT there is a table that we dont get called "Default trans limit" that we do not get in EFI Live and I think this may be playing a role in this problem. I believe this table comes in to play if it fails the tcm or if the tcm is not even present at all just like in this case.
PLEASE HELP!!!!
