IMPROVING ENGINE PERFORMANCE BY ADJUSTING ANGULAR POSITION SENSOR SIGNAL TIMING

摘要

Adjusting an angular position sensor signal of an engine operatively coupled to an engine controller, by, at the engine controller: Receiving signal characterization information having been determined based on an angular position sensor signal sample via a communications network from a remote computer system. Generating a time-adjusted angular position sensor signal based on the angular position sensor signal and the signal characterization information. Also, remotely characterizing an angular position sensor signal of an engine operatively coupled to an engine controller, by, at a remote computer system: Receiving an angular position sensor signal sample from the engine controller via a communications network. Determining signal characterization information enabling generation of an adjusted angular position sensor signal having an adjustment in time with respect to the angular position sensor signal based on the angular position sensor signal sample. Sending the signal characterization information to the engine controller via the communications network.
