Need tips on hall sensors and distributors

[Greg Hermann]

I _THINK_ you can program the SMC for any number of "trigger" teeth. If
this is indeed the case, the ring gear teeth on the flywheel might become
very tempting. They would certainly be quite accurate if this is possible.
This approach would leave you to use the dizzy for only a cam position
sensor.
