EFI Amazement!

I'm glad to see the Megasquirt project is still going strong. I was involved in the EFI332 project with the guys that eventually went on to create the Megasquirt. The EFI332 system was going to be an all out sequential fuel injection/ignition system with a LOT of capabilities due to the MC68332 CPU it was based on. Unfortunately, between the complexity of the TPU system (which is what gave the '332 it's power) and the VERY poor support from Motorola on the 332 and related MCUs, this project eventually pretty much faded away with only a few engines ever running on it.

Megasquirt was far simpler and FAR more successful! Good to see it's STILL up and running!

I've been reading through yours and Stan's pages, along with a lot of the Bruce and Al's stuff.

I do have one question: It looks like a lot of trouble (and cost) went into finding a good VR sensor. The microsquirt can accept dual ignition inputs directly, which is EXACTLY what our bikes output (pickup coils) from the factory. Is there any reason you went to the trouble of making a timing wheel and going with a different sensor instead of just locking out vacuum advance and using the existing outputs? It should be a lot cheaper and a LOT quicker to implement.

It was because we used the GM DIS ignition module as well as the coils. We used the corresponding 4 cylinder type DIS reluctor wheel.
