Abstract
An ignition apparatus for use with an internal combustion engine to produce an electrical spark at a spark ignition device. The ignition apparatus includes triggering circuitry having a processor with stored timing data. The processor receives a signal indicative of the rotational position of the magnet and generates a triggering signal. The triggering circuitry switches between a first mode wherein the triggering signal occurs at a fixed time relative to top dead center and a second mode wherein the triggering signal occurs at a variable time relative to top dead center based on the stored timing data.
