BMW M20 Cranking Sync Loss

[quan3165]

I am having trouble diagnosing the cause of my sync loss during cranking. It seems like I got good steady cranking RPM and consistent spark before I took this engine out for a rebuild, but it is back together and I have no spark. Not sure where I went wrong.

MS3 v3.57 w/ MS3X logic outputs to a Quadspark module which drives my EDIS-6 coils for wasted spark (i.e. no EDIS module)
Factory BMW 60-2 wheel & sensor w/ 10k resistor in line

I tried a few tooth 1 angles but I don't know what I'm looking at well enough to know whether that's my problem. MSQ, composite, and tooth logs attached.

I'm seeing some noise pulses; try adjusting the VR trim pots for less sensitivity.

So if I am understanding and reading correctly, R56 on the v3.57 board should go clockwise as a start. I'll post back in a few minutes with results.

R56 went clockwise 1 turn and RPM is much better, pulses that shouldn't have been there went away. thank you.

Still no spark- any ideas on that? +12V to Quadspark and coils are good, grounds are good.

Without a scope, how do I test:
-0-5V logic output from MS3X to QS module (I tried a test light but couldn't see any dim flashes while cranking I would expect)
-High current signal from QS to coils
?

do the coils fire when using test mode?

Turns out the dwell was set too low. I started around 2ms (nothing) and ended up around 5.5ms cranking dwell. Thanks to all for the assistance!
