One would believe if an idle speed is specified the ECM would just attempt to keep the correct idle speed no mater what the load is. However, I acknowledge the AIR input it wasn't added as a whim.

System type/manufacturer should not matter. All systems have a 12v signal to activate the compressor clutch. Just route that wire through the ECM (utilizing a relay on the output. The output is a ground reference signal) and done.
