Processor Assembly

The processor assembly is housed in an aluminum case and contains circuits designed to:

• Continuously sample input signals from the sensors.
• Calculate the proper spark advance, air/fuel ratio, EGR flow and thermactor air flow.
• Send out control signals to adjust spark timing, air/fuel ratio, EGR flow, thermactor air mode, evaporation canister purge and idle speed.

The processor assembly also provides a continuous reference voltage of 9.0 volts to the sensors.
