My AFR liens out at idle when ever I turn the AC on, About 2 full points. MY idle AFR is tuned to about 14.0 (my Pro 3's like them there) and goes to about 16.0 with the AC on. I can't figure out why? ELD on, swapped Alternator, P28 ECU. I don't want to tune/richen up the higher columns where the AC on idles as this just would richen up those columns way too much when the AC is off.
I also tried the S300 RDX Injector dead x's as I"m running them, but I put back my dead times from an RDX Injector test done at 50psi. (They work better/smoother) but made no difference.
Am I missing something here? Possible bad ecu? Car runs good but I need my AC and the constant liening at idle out is driving me nuts.
I've attached a 2 minute Datalog, at 2 seconds I turn on the AC for about 43 seconds, turn off for a bit and back for a bit and and then back off.
Any help or insight would be great!

Re: AC ON A/F Ratio liens out.
It is running in different columns when the AC is on, and it probably just needs those fuel tables tuned better when the AC is on.
