ECU Tuning & Modifications
CAT / O2 Off
Off-road & export use only. This modification is intended for vehicles used exclusively off public roads, or for export to regions where it is legally permitted. It is your responsibility to ensure compliance with local legislation.
Service Overview
Running a decat exhaust or sports catalyst? Without an ECU remap, your vehicle will trigger persistent O2 sensor and catalytic converter efficiency faults that cause check engine lights and potential performance restrictions.
We remap the ECU to deactivate O2 sensor monitoring and remove CAT efficiency checks — keeping your vehicle running cleanly with your upgraded exhaust setup. For off-road and motorsport use only.
What's Included
- CAT efficiency fault code removal
- O2/lambda sensor monitoring deactivation
- Decat exhaust compatibility
- Check engine light elimination
- Compatible with all decat & sports cat setups
- Petrol & diesel support
