General Motors’ Computer Command Control-System Development

Major technical advances have been introduced in the area of engine controls over the last several years. General Motors has applied many of these product advances including a digital microcomputer to coordinate the major control functions of the engine’s operation: fuel, spark advance, idle speed, EGR, and transmission. Motivation for these advances is based upon maximizing fuel economy and driveability for the customer while achieving effective emission control performance.

This paper will provide a description of the systems that have been introduced nationwide in 1981 and 1982 and highlight some of the production activities that were undertaken to ensure quality and reliability.
