AMC computerized engine control

The Computerized Engine Control or Computerized Emission Control (CEC) system is an engine management system designed and used by American Motors Corporation (AMC) and Jeep on four- and six-cylinder engines of its manufacture from 1980 until 1987, and then through 1990 by Chrysler after acquiring AMC.

It is one of the three major components for proper engine operation: the computer, electrically controlled carburetor, and the oxygen sensor in the exhaust system. In 1986, AMC advanced to single-point Throttle Body Injection (TBI), enabling an Electronic Control Module (ECM) to manage engine operation.
