BMW 60-2... i have been receiving conflicting replies.

James gave me:

Try this:
Trigger angle = 60 BTDC
Cranking advance = 12
Trigger A = 46
Trigger A return = 54
Trigger B = 6
Trigger B return = 14
Trigger C = 26
Trigger C return = 34

I have received diff info from E30Tech.com - this is on a BMW M50 motor. I modified the M30 diagram to be for the M50... thats what my M50 looks like @ TDC.

What is the other info you received and are they running it?

That would seem right to me based on this digram. 10 teeth (60 degrees) BTDC is tooth 46

My #'s for M30 are totally different though

James - they keep giving me M20 figures I think, different motor different TDC vs VR Sensor position and the gap is at a different spot than mine... i think yours is right

Jon k - is that tooth 56 or 57 under the sensor at TDC?

That's the leading edge of 56

Jon_k, are you going to tell us the other advice you've been given?
