HEI Ignition Coils

KitCarlson said

You seem to have my interests.
I used ignition IGBT with added BJT and resistor, skipped HEI modules, did dwell and advance with uC. DIM Electronic Advance Ignition
Also did COP system COP Ignition Development, and EFI systems with ignitions.

I am willing to help if you ever need it.

Wow, that's really cool. I have the basic programming written for the micro controller part of it. Just need to test it and then debug it. My plan was actually to try to do a coil on plug setup after I got this HEI system working, too. The real restriction seems to be dwell overlap at high RPMs when there's just one coil from all the math I've done on it. Just can't charge the coil enough fast enough when there's only 3 milliseconds to work with between dwell and advance.
But anyway, the main reason I wanted to include the HEI module was that I wasn't sure how the pulses from the reluctor would come in and how to translate that into the full pulses I need. I assume the HEI module is probably taking an analog pulse and sending a digital pulse that has the same length. Removing the HEI module from the equation is probably the next step after I get it working this way.
Right now I'm having trouble getting my car to start at all with just the uncontrolled HEI module... I've wired this thing up every way possible and it just doesn't want to go... Actually just came in from messing with it for almost 3 hours. Starting to wonder if I got a bad module. I tested it with another Mopar electronic distributor I had laying around and it was pulsing out the negative terminal, but no clue if that means it's actually passing enough voltage through to be effective or not.
And thank you for the offer, I will need help at some point with this, I'm sure.
