Abstract
A timing control circuit for a strobe lamp for use in adjusting the timing of an internal combustion engine. A circuit which provides for retarding lamp triggering for setting ignition advance and for advancing lamp triggering for setting ignition retard. A circuit providing for advance and retard selection, the amount of advance or retard, and zero degree triggering for engines with various numbers of cylinders. A circuit with a ramp voltage synchronized with engine timing, a reference voltage for setting the amount of advance or retard, and a comparator which provides a triggering signal for the lamp when the ramp and reference voltages match.
