Simon Posted April 22, 2014 Report Share Posted April 22, 2014 By default we put out a pulse per TDC. So the tach would need to be geared for the number of cylinders in this case two. It could be that the tacho is geared for a coil negative signal in which case the ECU will not be able to drive it. Quote Link to comment Share on other sites More sharing options...
