Abstract:
A system and method for providing multiple commands to an ignition coil driver circuit to provide spark, ion signal integration, and ignition coil shunting during a cycle of a cylinder is presented. In one example, multiple voltage pulses are provided over a single conductor communication link. The voltage pulses provide encoded instructions for ignition timing, ignition coil shunting, and ion signal integration.
