Guess I have reached the point I am desperate enough to give someone $100 to show me whats wrong. I'm 99.9% sure it's in the software, probably with the injector tuning. Gets worse with increasing ECT temps. Breaks up and backfires under load when you try to go WOT in the 4000-6000 rpm range. AFR spikes up when it does but injector duty cycle stays up. Runs good around 125 degrees but goes to crap by 150 degrees ECT. Motor ran great in my truck but will not in the Camaro.
Some specs:
98 Camaro
LS7 427-large cam-ETP heads-GMMP carb style intake-90mm TB
Powerglide trans with 5600 stall
99-04 style computer and new stand alone harness
48lb Racetronic injectors
Aeromotive 1000 pump and system (fuel starvation is not the problem)
Truck coils
Base tune is from 2001 Camaro
Crank sensor and cam sensor have been checked and replaced and checked
No VSS
All grounds and + cables have been ohmned
Will PayPal $100 to whoever pinpoints the problem.
On the log start at frame 465 for the good WOT and frame 3142 for the one breaking up.
