Hello everybody, I am a bit confused about the tacho pin #36 of the DB 37 I think. Is this how to trigger the coil? Also, The tachometer that I have used to be controlled by the stock ecu, how do I send it a signal form the Megasquirt (V2 3.0)?

Re: Tacho
Tach signal MS wise usually refers to the RPM signal from engine to MS. Pin36 is that tach *input* to MS.
To derive a suitable signal to drive your tachometer, check the manual for how to.

Re: Tacho
Pin 24 is the tach input; pin 36 is a spark output. Did the factory tach run off the coil or off a 0-12 volt signal?
