I'm using Turbonator LM, and I have a working a/c, when I turn it on, my a/f goes to 11-12. Shut it off, A/F goes 12-15.
Is there a fuel table that richen up when a/c is on?

I don't remember seeing anything like that in the fueling tables or in the aux functions. How much does your idle drop when the A/C kicks in?
I think you're going to be stuck tweaking the PumpingEfficiency table at low RPMs to get the A/F where you want it.
There is a fuel battery offset table that increases injector pulsewidth based on batt voltage drop...could work, but only if you're seeing "lowish" voltage when you're fans kick on.
..Could be that you've got lower vacuum when the A/C kicks in...causing the fuel pressure to rise a little. Remember the FPR uses vacuum to lower FP and boost to increase it. Ok, I'm going to stop thinking about this, there's a lot that could be affecting it.
There's no specific fuel enrichment for AC on/off. But, there is a transient enrichment, for TPS, MAP, and for AIS motor. When the AC is switched on, the AIS motor opens a little bit to compensate. You can try adjust the AIS transient enrichment to compensate.
Sounds like maybe it's a little too much enrichment.
They're under 'pump shot'...
I have the details about how they work on my Wiki.
Awesome. Been tempted myself after dealing with some gremlins on my two TD's.
