#5194, "RE: Another MS Install!" In response to In response to 0
You have it for the most part. I personally would use the MS to control the fuel pump relay. As far as the sensors go, you can use the stock 420a sensors if you are using MS2/E code as you can set the temperature curve and resistance values. As far as I know MS1/Extra code needs the GM sensors. Tuning will be difficult with a narrowband O2 sensor. If your friend wants to go this route then you can send the signal to the MS unit as you described. He will not be able to dial the tune in very well though using this method.
