I have a 2010 Camaro SS with a 2.9 Whipple Supercharger on it with a stock cam & SD 60's. I've been trying to figure out a random rich (10.0) / lean (16.0) idle situation. It is consistent issue and everything I have tried hasn't seem to work. The condition is also present at extremely light throttle acceleration till about 2000 rpm or so and disappears. I have also seen a rich condition during deceleration. I have played with (B1203) Minimum Injector Pulse Width and it hasn't seem to help. I have seen threads on CAX files for earlier LS1 PCM's, but nothing for the E38. I believe it was a transients minimum pulse width table B9021. My OS is 1267084 & Calibration is 12637083. Any hints to point me in the right direction would be appreciated.
Thank You,
Dave
