Crank Sensor
An HEI module {$20 at any parts house} will generate the 5v square from the Mopar magnetic pick up, but the lack of #1 reference, and the movement of the advance mechanisms all contrive to cause issues.
I need two separate signals, one to fool the PCM, and one to trigger the coil using the curve of choice. Sounds simple when you say quick it doesn't it? :D
