MOTORCRAFT EEC Ignition: Description

All Lincoln Versailles models are equipped with Electronic Engine Control I (EEC I). Some Ford and Mercury 351" W engines are equipped with Electronic Engine Control II (EEC II). The EEC systems consist of an Electronic Control Assembly (ECA), various sensors, and modified Dura-Spark II (Dura-Spark III on EEC II) ignition module and coil.

The distributor used with the EEC systems does not use a pick-up coil, armature, or any vacuum or mechanical advance mechanisms. All ignition timing is controlled by the ECA based on engine operating conditions as sensed by sensors. The ECA is capable of firing the spark plugs at any point from TDC to 60 degrees (50 degrees on EEC II) before top dead center.
