forget an adapter for a later model dizzy............

What would be cool, is a fully electronic bolt on 'distributor' that has the sensors and electronics built in to run either an EDIS style dual coil for wasted spark or individual coils for full sequential. The only connections to it would be power, vacuum for advance, outputs to the coils, and some kind of communication port for tuning.

My thoughts exactly!!

If you're using a setup like that, why would you need vacuum advance? It would be electronic at that point. What about a microsquirt-style ECM that has as many sensors as possible in the "distributor" housing? Add a crankshaft position sensor and you're pretty much done at that point.

You still need a way to measure engine load. For most older engines that would be manifold pressure. On newer engines you could use the MAF sensor if there is one. Or with ITBs/Webers you would use throttle position.

The idea would be to keep it as simple as possible (and bolt on), so no crank sensor. The only issue with it is that you need to use components that can withstand the large temperature swings (and vibration) in an engine compartment. It would be neat though to have EVERYTHING in the distributor housing, even for fuel control.

Many competition chainsaws run microsquirt, so they're built for vibration and high heat. With something contained within the dizzy, you're eliminating many of the other sensors. You're still going to need a TPS signal, and as you said, engine load. MS includes an onboard MAP sensor, but the microsquirt does not. The ultra common GM 3 bar sensor can be used, though.

Oh that's right, the Microsquirt was designed to be weatherproof for small engines. I don't think it will do sequential injection on 4 cylinders though. I'm pretty sure it only has two injector outputs so it's batch fire. Not that it will make that much difference.

It would be very cool nonetheless.
