COP Ignition Development

Here is the sensor waveforms applications planned for my system.

The top is a 4 tooth wheel on the crank, it would be used with distributor 1/2 circle. The half circle is OEM distributor sensor on some magnum engine. This is simple and requires little decoding by micro controller. The cam sync can happens at 360 degree crank intervals. The cam/crank method could also be incorporated in distributor housing by adding second target wheel and sensor.

The bottom is a single sensor tab wheel with window in one tab for sync. The sync happens at 720 degree intervals. The single sensor is low cost, and mechanically plug and play.
