My two cents. If you're keeping your stock ECU around soley for the purpose of of IAC I think you're wasting your time. I've so far megasquirted two cars with no IAC, not even a fast idle valve with very good luck. Your mileage may vary as some vehicles will be more apt to function okay with a wide variance in idle air intake. Vehicles in areas with wide temp fluctuations may also not work as well but my suggestion is to try it and see. You might be suprised. Also, rigging a MS-compatible Solenoid style IAC might be a much easier alternative to trying to appease the stock ECU.
