Electronic Engine Control I: Description

The Electronic Engine Control I (EEC I) system is used on 1978-79 Versailles 302" engine equipped models. The system is designed to precisely control ignition timing, EGR flow rate, and Thermactor air injection system flow rate.

The EEC I system consists of an Electronic Control Assembly (ECA), 2 pressure sensors, 2 temperature sensors, 3 position sensors, Dura-Spark II ignition system, air pressure-operated EGR system, and Thermactor air by-pass solenoid.

The sensors monitor various engine and ambient conditions and send electrical signals to the ECA for processing. The ECA computes the correct ignition timing, EGR flow rate, and Thermactor air injection flow rate for the best performance and emission control.
