Spark Table Switching for Idle -- Question for Brain
Brain, looking at doing the spark table switching to handle idling AC load. Curious whether you are running in Closed Loop or Warmup mode?

I use Spark Table Switching with A/C activation and Closed Loop Idle Control.
I have my spark map advanced at idle and retarded 1-2° throughout, when the A/C is running.
The ground to my A/C Switch is tied into JS5, which triggers the event. It also triggers my A/c Idle Up Activation.

Very nice. Thanks.
I really like this option because the A/C clutch signal is already in the ECU harness -- minimal wire surgery. Plus, it seems like it should work really well.
What's the reason for retarding the remainder of the map 1-2°?
