I built a crank trigger some years ago for a 440 but in the end I had to buy an aftermarket "brain" to be able to set the parameters. I don't remember where I found it or the manufacturer and I don't care because it was expensive and I like to be cheap.
Is it possible to find something useable on a junk yard? Wheel and sensor you can buy anywhere, but the rest?
I'm not going EFI, I just want an excellent ignition that sparks exactly where it should
