I have a M10B18, an I recently got finished wiring the Megasquirt. I got a Base tune and had to change a few things from that tune. One of the settings I had to change was the ignition trigger, I am using the factory distributor with the factory V.R sensor. I made sure the V.R sensor on the distributor worked and it puts out 1.1 V a/c ~ during cranking and I double checked my harness to make sure my wiring was correct, an the signal is getting to the 32 pin connector / MS controller. Which it is, I'm getting the same voltage to the connector so I am positive the MS controller is receiving the signal. I went to the settings and made sure it was set to "one coil" and "basic" trigger input. When cranking the dashboard of tuner studio with my tach is showing no engine RPM. So I want to know if I didn't set up the ignition right or what??? thanks for all POSITIVE feedback. I have 2 post with my engine build info but ill put it on here too.

also its not a square wave its sine wave signal... could this be a problem?Comment

sine wave out of the VR sensor is expected.
Have you done a trigger log? What does it look like?'84 318i M10B18 147- Safari Beige

I figured that, I was just at a loss...I didn't not do a trigger log, but I did find the problem...I had the wires of the sensor mixed up.. that one was 100% my b lol.. so all good nowComment
