I am working on a m6 ls3 camaro. it has 233/247 cam, full exhaust, cai, minor cylinder head work. basically when its hot and you try and start it fires then stumbles for a sec then it flares and runs perfect. i have tried adjusting cranking ve, cranking fa multiplier, startup air, cranking timing, i tried reducing the idle under and overspeed to 2 to see if that helped, reduced startup flare control to zero and everywhere in between. nothing seems to get rid of this and it doesn't do it when wold only when engine is warm. if you watch the log you can see that the timing is around 12 then it fires and goes to 0 (this is when it stumbles) then flares up but i cant seem to figure out where the engine is getting that number as the flare control and cranking spark tables only go to 800 and if you subtract the flare control from idle spark and low/high octane at that point the numbers dont match. I believe the base running airflow to be correct becuase if i turn the idle spark off (on) in scanner it idles right where its supposed to. thanks for any help in advance.
