Disclosed is a reluctor plate controller that detects vacuum and pressures in the engine which are used to create digital motor control signals for controlling a reluctor plate actuator using a digital stepper motor, servo motor or a voice-coil actuator. The system can be programmed to create various desired responses that function to create better efficiency of an internal combustion engine, less pollution and/or greater engine output.
