    MegaSquirt help

    I searched and didin't find anything, so I figured I'd ask.

    I'm wiring my MS in this weekend and I was told that I need the info to put in for the Coolant Temp sensor, like what reading you get at certain temperatures. Does anyone know this, or should I just pick up a GM one?

    I have the MS1 v2.2, the DIYAutoTune harness, tuning cable, and I'm getting the coils, IAT sensor, and Coolant Temp sensor. IS there anything else I need, or just wire everything up and tune?

    You just need to change the software. Have you heard of EasyTherm? Look that up, it's a piece of software that allows you to calibrate the MS box so that it works with your stock sensor.

    When you are saying coils, are you planning on running wasted spark? Do you have two ignitors wired in on the MS board?

      I know this thread is old but I'm still confused on some of this.

      I have a 4 wire TPS, but there is only 1 TPS wire on the MS harness. How do I wire the TPS to the MS harness?

      Which wire on the distributor do I use for the IGN input signal?

      Which wire around the coil do I use for the tach signal?

      Thanks in advance for anyone who offers any help.

        Ok, so I think I got most of it figured out last night, I'm still a little confused on the TPS though.

        I was told I need a 4 wire TPS. There are 2 TPS wires on the MS harness, and I assume you'd run a ground for the sensor, so that means 3 wires. Where does the 4th wire come in?
