Spark Control Computer (SCC)

The SCC controls the entire ignition system. It is capable of igniting the fuel mixture according to different engine operating conditions during a run-drive period by delivering an infinite amount of variable electronic spark advance curves.

The SCC has a built-in microprocessor that continually receives input from different engine sensors to enable the computer to electronically retard or advance the ignition timing and adjust the air/fuel mixture to assure the most efficient fuel burn possible.
