Fig. 26 E.C.C.S. control unit.:

The ECCS control unit, Figs. 26, 47, consists of a micro-computer, connectors for signal input, output, and power supply, and an exhaust gas sensor monitor lamp. Electrical signals from each sensor are fed into the control unit. The micro-computer stores information and computes the correct electrical signals to be transmitted to the electrical actuators to control engine functions. The ECCS control unit controls fuel injection, spark switching and timing, exhaust gas recirculation, air control, idle speed, fuel pump operation, mixture heater operation and mixture ratio feedback, depending on application. In addition, the barometric sensor is contained in the control unit.
