Anyone have an address location and definition for the iac steps taken when the A/C comes on? I'd like to reduce the rpm the car is at when the A/C is on. IAC is set correctly but when A/C is on idle rpm is around 1000 and whould like to reduce for better driveability.
I see iac a/c related values at $651 and $694-$696 but not sure how to manage them.
Thankx,
Mark
 
It appears $3694 is the value you want to change. If I read it right the cal says "When you turn on the AC, raise IAC counts by 44.

F445: FC 36 94 LDD $3694 D = IDLE SPEED A/C COMP (=44 STEPS)

Try lowering that value. Keep in mind that AC performance will suffer with too low an engine RPM.
