Lambda Delete

Lambda / Cat / O2 Delete

When decatting a petrol vehicle (for a stage 2 or custom tune), it is likely that an engine management light will be illuminated, and a fault code for cat efficiency will be stored inside the ECU memory. By careful recalibration of the engine ECU data we can disable the function of the second lambda sensor.

The second lambda sensor is used for monitoring the efficiency of the catalytic converter. Disabling the second lambda sensor will allow a decat or high-flow pipe to be used on a vehicle without triggering an engine management light or associated fault codes.

Decatting or High-Flow catting a vehicle normally triggers a P0420 fault code (Catalyst System Efficiency Below Threshold (Bank 1)). Our lambda delete service will permanently remove this fault.

*Our lambda/Cat/O2 delete service is intended for off-road use vehicles only. Deleting the O2 sensor is likely to make your vehicle unroadworthy for use on public roads. As such, Gold Coast Euro Tuning cannot be held liable for any infringements imposed upon our customers by the TMR or RTA.
