[QUOTE="bubblehead93, post: 15269291, member: 96609"] clarification, if operating closed loop it will idle at stoic or (as may be case, since car is with tuner) he is forcing open loop, then the tune, specifically the MAF transfer table (and others), as the car is not using feedback from the O2s to maintain stoic (really just bounces around it based on how the O2s and PCM work)... interesting the apparent effect on idle AFR, too many questions without access to the tune and data logs, there are specific tune parameters for A/C since it is such a load on the system when the clutch locks on the compressor... r/ Andy [/QUOTE]
