Need Help LS2 Procharged & cammed.

[jhutchinshh]

Hey guys, I need some help with a customers 05 C6 automatic. He had a cam installed couple years ago by another shop and came to me wanting to procharge vette on top of priovous work. The car has 230/242 595/595 lift cam and procharger 6psi, long tubes with full exhaust. Runnig operating system as SD and 2bar map but haveing trouble with idle fluctuating when first start up or coming to stop in gear. I knew this car would test my tuning abilities but to be honest its kicking my butt. Any help would be appriciated.

I'm having the same issues with a nearly identical build. When I get home I'll look at your map and maybe we can put our heads together and solve both our problems.

I need help in the same way... 05 gto cam unknown F1 Procharged , I'm going crazy!

Yea I am still waiting on help. I have been working on this stupid thing for over a week with no luck. Car runs great just has idle fluctuation and at times a bump (feels like a miss) while idling in gear. In a recording i can see that everytime it bumps the spark advance jumps sometimes as much as 8 degrees. Someone please help!!!!!!!!!!!!!!!!!!!!!!!!!!

Adaptive idle settings and various response towards that ..... thats usually apart of a jumpy idle issue.... check idle airflow etc for that adaptive idle and the spark control area for adaptive idle
