Some Link G4X Fury ECUs contains an Internal Wideband Lambda Sensor Controller. This allows the ECU to be connected directly to a wideband oxygen sensor without the need for an external controller.

 

Advantages of using the on-board controller include:

·Better oxygen sensor fault detection. External controllers often do not communicate sensor faults to the ECU.

·No external controller required, save costs, time and simplifies install.

 

The Internal Wideband Lambda Sensor Controller supports the Bosch LSU 4.9 oxygen sensor. The information below is provided to help with installation:

Important notes on fitting wideband Lambda sensors:

·Sensors should not be installed vertically in the exhaust pipe. They must be installed with some angle to ensure that a moisture drip could not form directly on the end of the sensor.

·Ideally they should be installed between +/- 60 degrees of horizontal.

·Do not leave a wideband Lambda sensor in the exhaust without heater control. Heating is required to burn carbon deposits from the sensing element. Remove the sensor completely if it is to be run without heating.

·Locate the sensor far enough down the exhaust system where exhaust temperature does not exceed approximately 730-750 degrees C. This will ensure the sensor is able to control at its correct temperature (780 degrees C). Watch the Lambda x Temperature parameter to ensure sensor temperature is being correctly controlled.

·Do not locate the sensor so far down the exhaust that it is unable to fully heat.

·Do not locate the sensor where exhaust pressure is significantly different from atmospheric pressure. Lambda measurement will be affected by exhaust pressure.
