I think it may be pulse although not certain. I have the Pin 48 from the ECU connected to my Acewell Digidash 7659 and that reads the signal just fine. The manual for this states CDI or ignition coil signal.

Hope that helps.

Hi guys,

Just to let you know, it is a negative pulse, 2 pulses per engine revolution
