The Electronic Fuel Control system (EFC) is used on all carbureted 1.6L, 1.7L and 2.2L engines with front wheel drive. EFC is an electronically controlled system that closely controls air/fuel ratio and ignition timing. The Spark Control Computer (SCC) is the heart of the system.

This computer provides the capability of igniting a lean air/fuel mixture according to different modes of engine operation; plus, during closed loop operation, the computer maintains the air/fuel mixture close to the ideal ratio of 14.7:1.
