1970 Chevy El Camino, LM7 Engine, 4L60E - Two 896 and two 0411 PCM's
Will check..
i stumbled on a post on HP tuners about this and the fix is:
set Alt F-term to 0
set on engine diag P1638 to 0
i will update later when i work on it.
Well i fixed the battery light, but now i have a missfire and it wants to accelerate itself.
