Hello, I just did a cam swap on my 05 Gto and I can't for the life of me get the idle sorted out. Mods include e85, procharger, longtube headers, magnaflow exhaust, and a ccp jam cam which was the only thing done during the cam swap, all other mods were previously dialed in on last tune.(Running speed density)
Cam specs are: 230/242 .608"/.615" 115+4
I have tried following step by step guides posted online but the gto is lacking many of the parameters that get edited and I can't seem to find a clear guide to dial in the gto's idle that's unique enough to work for it.
I've tried modifying many different parameters without much luck, airflow final min., base spark, etc. Car would sometimes maintain idle at 1000, and then other times drop down to 300 or 600. I took it for a very quick test drive trying to see how it drove, it was late at night so I tried to keep moving to not upset the neighbors too much. Car would sometimes randomly die while coasting or stopping. It didn't want to crank back up after warm either, I lowered the cranking ve and I think it helped. I attached a log file of this along with my current tune file. Fyi, I already updated the VE table in this tune after seeing the log file. Airflow Min. final table is currently zeroed out.
