MD MS2 Ver3.0 w Relay Board Wiring
Wiring a TII into an S5 NA chassis ... I'm using a MS2 Ver 3.0 with a relay board to simplify the wiring, but I am confused a bit with the CAS installed to the relay board. I have a writeup from DIYautotune that says the white wire goes to the sensor return terminal. On the relay board there is no sensor return. There is a TPS sensor return. Would that be the same??? That is currently unused since I connected the TPS ground to the CLT ground in the harness following the writeup by Aaroncake.

So ... All help would be appreciated.

Yes, wire the white wire to any of the sensor returns. These are all ground

If they weren't able to help, keep trying. I've never seen a case where they weren't able to help.

Give us a little bit more info. Is the megasquirt reading rpm?

What kind of wiring are you using for the CAS? What are your settings?
