Thanks for the replys. I'm going to bail on the GM HEI and move to a trigger wheel with a Hall sensor. I've read this will improve timing and provide a quality square wave to Megasquirt. Anyone running the DIYautotune trigger wheel and hall senor with MS2 V3 setup for hall/opto?

Thanks for the reply. What trigger angle would you use as a start?

I'm new to the Forum and looking for help with the set-up for a MS2 on a L28 na. The distributor has been locked. The ECU was set-up for Hall/Optical because the service rep thought incorrectly that my distributor was CAS. I could reconfigure for VR input however I have tried something I read on line and that was to wire the VR signal to a 4pin GM electronic ignition module to convert the AC VR signal to the square pulse the MS2 Hall needs. I have RPM when cranking. I have fire at the coil output. The car will start but the timing is way off. Has anyone setup the L28 na that would share their MS2 configuation?
