Just setting up my EMU for first start up on a boosted m52 hybrid engine. I just need help figuring out the trigger wheel settings. I'm using the trigger wheel that is on the crank itself not the damper pulley. I was told it was a 60-2 wheel, but I have no idea what degree the first tooth is at or what the trigger angle is.

And as far as the cam position sensor, I have no idea anything about the wheel on the cam. I'm using the OBD1 sensor but I don't know anything about the wheel itself..

Anyone care to share their trigger wheel settings?

Tooth 5 angel 54 or tooth 45 angel 54. Depending on wich year it is.

Crank is a s52 crank from a 97 M3

Simply use strobe light ........ whats the problem ?

for m50TU (vanos) and m52/s52 internal crankshaft trigger
tooth 5
angle 54
ignition output offset 5

for early m50 non vanos all the same settings but ignition output offset 0
