This is research on the "IC-Ignitor" for mid-80s' motorcycles. The target platform is a 1985 Honda CB650SC. Which is a 655cc 16-V DOHC I4 with individual carburetors. The ignition system is fully electronic, TCI, with two ignition coils (wasted spark). The CPS(Crank Position Sensor) is a "pulse generator" setup. It utilizes two "pickup" coils. The output signal is Variable Reluctance(VR). There is a single "wiper" attached to the crank. Each sensor will be pulsed once per 360° of rotation. The first sensor is pulsed at #1&3 TDC. The second sensor is pulsed at #2&4 TDC.
