I think it's possible. Just let you megasquirt contol fuel/spark etc... let your original computer control AC

Mr. Whitefinish is correct. Its fairly common to leave the stock ECU in place to control things like AC.

Air conditioning: While the stock ECU controls the air conditioner, you don't need a computer to make this work. Wiring the A/C request wire running to the ECU to the A/C compressor relay should make this work, although we have not tested this one for ourselves. The MS3X can control A/C using one of its on/off inputs and a medium current output.
