ABSTRACT:
An electronic advance and ignition control system incorporating the advance utilizes a fixed advance threshold compared with amplitude of an RPM sensitive input waveform from a distributor in combination with a timing circuit, which establishes a predetermined RPM rate above which the advance operates. The electronic advance accurately duplicates the function of conventional centrifugal and vacuum and advance retard mechanisms in controlling timing of an ignition coil drive signal. The electronic advance is provided as part of an ignition control integrated circuit which can operate in a stand alone mode or share control of the ignition system with a microprocessor through interface circuits also forming part of the integrated circuit.
