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.
