Processor Assembly

Housed in an aluminum case, this assembly continuously samples the 7 sensor signals and converts them to a usable signal for the computer. It also performs ignition timing, Thermactor and EGR flow calculations, and sends the proper electrical signal to the ignition module, EGR and Thermactor air control solenoids to adjust the timing and flow rates as required.
