Spark Combustion Computer

The Combustion Computer controls ignition system and air/fuel ratio of carburetor. Electronic Spark Advance (ESA) system is new in determining spark advance by engine speed and vacuum only. Start timer, vacuum transducer count-up clock and memory, throttle transducer and ambient air temperature sensor are not used. Computer consists of 1 electronic circuit board with a microprocessor that processes signals from all the sensors and within milliseconds computes them so that proper ignition timing and carburetor mixture is immediately achieved. This digital electronic circuitry offers more operating precision and programming flexibility.
