Spark Control Computer

The Spark Control Computer (SCC) is the heart of the entire system. It gives the system the capability of igniting a lean fuel mixture according to different modes of engine operation by delivering an infinite amount of variable advance curves. The computer determines the exact instant when ignition is required, then feeds the ignition coil to produce electrical impulses which fire the spark plugs.

The computer consists of one electronic printed circuit board which receives signals from all the sensors and within milliseconds computes them so that proper advance or retard is immediately achieved.
