Anyone else using MegaSquirt on a LA motor?

What does the trigger/tooth capture in tunerstudio look like?

I for one had one hell of a time with a mopar variable reluctor trying to pick up cam rpm, I believe it was due it’s low starting speed. I played with the gaps, made sure the poles were correct, a heavier shielded signal wire; I could not get it to start and run as described in the post from me above.

The 36-1 trigger wheel really saved me but was difficult to fabricate the pickup mount and to properly space and mount the trigger wheel to the crank. I got it all right and I still had issues. Finally installed a 1k ohm resistor in-line on the signal wire and it starts/run great now.

I would first recheck all the ms2 pcb connections and tunerstudio settings. Then try and crank and watch the tooth logger. Adjust hysteresis per megamanual/diyautotune. Get it to pick up the rpm. If you have noise, You may be able to get a better software version for ms2 that will help with the noise. Then I’d simplify it by ditching msd and use the Bosch bip373 Coil driver and a diyautotune coil. It’s cheap, cost is <$10 for the driver and the coil is <70.

If all else fails, go with a 36-1 trigger wheel. Don’t use a step drill to bore the hole like the guides say. Take it to a machinist who can bore it out with concentricity.
