Note: Refer HERE for information on wiring wideband Lambda sensors to the ECUs internal wideband controllers.

 
Wideband exhaust gas oxygen (EGO) sensors are able to accurately measure air/fuel ratios over a very wide range from very lean to very rich. This makes these devices very suitable for tuning purposes.

A wideband sensor can be used to run Closed Loop Lambda (CLL) for improved economy and emission. A wideband sensor is a necessity if Quick Tune (refer to the PCLink online help) is going to be used to tune the engine.

Some G4X ECUs accept the signal directly from a wide-band sensor otherwise a CAN input or any Analog Volt channel may be used to accept the signal from a wide-band EGO sensor controller. Note A wide-band controller works as an interface between a wide-band O2 sensor and the ECU. The controller should connect directly to the sensor and output a voltage between 0 and 5V when connected to an Analog Volt channel. The sensor calibration (the voltages that correspond to given air/fuel ratios) must be known and this information must be entered into the ECU via PCLink.

 

The Link CAN-Lambda external Wideband Oxygen Sensor controller is recommended if the ECU does not have an internal controller.
