Bruce, are you doing all the wiring/plumbing and programming? It's a steep curve, and while very well versed in wiring, electronics, and programming, I haven't taken the plunge yet myself. There are books out there, I'm sure. Probably a good thing to read at night. I'm sure they'd put me to sleep. I'd read them in the morning with a cup of joe.
I've been thinking about it for a while Stan. I was looking at Speeduino(you solder or get one built, but still have to case it up and wire plugs in). I don't think Microsquirt can do drive by wire, but maybe. I think it's best to do batch fire on injectors and wasted spark for a first attempt. You could always add a cam sensor and a couple coils for sequential later. You know, once that learning curve flattens out a little.
