I'm sure this has been asked before and if I wanted to dive deep into the rabbit hole of the MS forums I could probably find the answer...but that hole is far too deep for me.
The question is simple--can I use one of the Megasquirt systems to solely control spark/ignition advance and retard? My car uses a Denso electronic distributor with mechanical advance and a MSD6A box. I run twin 40 IDF carbs--I'd later like to switch to ITB EFI but the Webers are great right now.
What are my options? Keep the MSD 6A and dizzy and use the MS to intercept the signal and base ignition timing off of rpm through the MSD box? Can I eliminate the dizzy and box all together and run coil on plug? Wouldn't that require some sort of pick up wheel and sensor mounted on the crank pulley?
Thanks! JP

Yes. You can either lock out the distributor advance mechanism, or for more accuracy, switch to a crank trigger.
