What is a PCM? I didn't realize the compressor speed can be modulated based on idle speed.

This maybe a crazy question but has anyone considered using an electric motor to power the A/C compressor instead of using the engine power? You could then use the Toyota compressor and still get the constant speed you need and not have to purchase custom hoses etc. I've seen electric motors for the Water Pump for GM trucks - is there such an option for A/C compressor, I wonder?
