Computerized Engine Controls Control Unit
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.
NOTE:
Components are grouped into 2 categories. The first category covers INPUT DEVICES, which control or produce voltage signals monitored by the ECU. The second category covers OUTPUT SIGNALS, which are components controlled by the ECU.
The Electronic Control Unit (ECU), monitors engine conditions through various input sensors, and controls engine operation through the use of output signals to control various systems 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.
