I am not sure how the ECU derives the RPM, if it's from the crank or from the cam - would assume the crank. I am also not sure how the ignition system works, but the above link has all the pinouts for the ECU.

RPM limit is hard coded into the ECU. You can only modify that rpm limit downward, and you modify the two ignition signals going to the ignitor/coil.
