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.
Thanks
what do you mean, it has its own? the vintage air just gives 12v to compressor yes, is that what the facotry GM ecu needs? then send that 12v to the ecu and wire the a/c circuit like factory.... just that easy
