The Catalyst / O2 OFF file is a custom modification of the ECU software. Based on your original file, we disable catalytic converter and lambda sensor monitoring (O2), suppress the related error codes and correct the checksums. You receive a ready-to-flash file that preserves the factory engine refinement – with no check engine light and no forced limp modes.
We prepare the file based on your original ECU read, not as a universal solution for multiple ECUs.
Deactivation of catalytic converter and lambda sensor monitoring after their removal or wear.
Once the service is complete, you receive the modified file online with correct checksums, ready for the supported ECU.
The service is ideal for workshops, tuners, automotive electronics specialists and anyone working on projects outside public roads – wherever a change at the ECU software level is needed.
