Where did you find the formula for the AC pressure voltage to psi/kPa? I ask because I was under the assumption that 0v = 0psi and 5v = 450psi....therefore, 1v = 90psi, 2v = 180psi and so on. That would mean you only need {voltage*90} in your formula for psi.

Cool - thanks! Think I found the thread over there. Been a while since I was active on the forums...
What happened to my A/C Pressure PID?!!

Well you have to make a custom PiD to log ac pressure. I will post up the equation tonight, it uses ac voltage to generate the pressure.
Well the problem is pretty much gone. I revisited my TF and TC tables, adjusting them slightly. Then i copied over the ac torque loss tables over from a 2002 camaro since ours the main torque loss table is zeroed out from the factory. I decreased the IAT table done some the. I started increaseing the main ac torque loss table. I kept increasing it until the surging went away.

Well those lean codes arent helping. But lower ther throttle follower decay rate. So increase the throttle follower delay. As for the warm starts adjust the startup friction table delay and decay. Increase the delay and decrease the decay. I hope that helps. PM if you need some help.

Eeeevery once in a while when pulling up to a light, something will keep me from going into adaptive idle and I'll get bad idle swings but it's rare.
