    Vehicle Speed Signal

    hello people, i;ve just installed megasquirt on my m52 engine. ms needs vehicle speed signal (as m50 has vss from cluster), but i cant find that pin on my m52 siemens wiring.

    this one is bosch m50. 42 pin is vss from cluster

    those are m52 siemens ecu pins. none of them i think is vss

    so what can i do? how to get vss for my ecu?

    Your Siemens DME likely gets its road speed signal over pin 15, "speed signal, right rear". I reckon it should should see 25130.7 pulses per kilometer, but please confirm both these things.
