What should I adjust in my spark tables? Idle area Im at 10% opt torque, 0 on opt spark, ~42 degrees normal timing commanded, and like I said above my DALs don't fix anything so I'm ruling that out. Also have my base idle set to 900, and my AC on idle set to 1150 and it doesn't help. I've tried raising it to 1500 just to see if it would do anything at all and it doesn't affect the idle quality or speed with the AC on.
