CEC System: Description

The Mazda RX7 computerized engine control system monitors various engine and vehicle functions to control engine operation and lower emissions while maintaining fuel economy and driveability.

The Electronic Control Unit (ECU), through various input sensors, monitors engine operation through the use of output devices such as fuel, air injection, ignition, EGR and turbo control systems. Knock control system is used on turbo models. Turbo operation is controlled by the turbo solenoid valve which receives controlling signals from the ECU.
