Cat Delete
Catalytic Converter Software Remove
What Is It
After physical catalytic converter removal, the ECU needs to be recalibrated to prevent error codes, limp mode, and emissions warnings. We adapt the lambda/O2 sensor readings and remove catalyst efficiency monitoring from the ECU calibration.
Benefits
When You Need It
After installing a decat downpipe, test pipe, or racing headers. Always combined with DTC Off for complete solution.
The Process
Frequently asked
What is Cat Delete?
After physical catalytic converter removal, the ECU needs to be recalibrated to prevent error codes, limp mode, and emissions warnings. We adapt the lambda/O2 sensor readings and remove catalyst efficiency monitoring from the ECU calibration.
How much does Cat Delete cost?
From €200. Combined solutions are cheaper bundled — send your make/model/year for an exact quote.
Is it legal / will it pass inspection?
For public-road use in the EU, emissions systems must stay functional to pass KTEO/MOT. Cat Delete is intended for off-road, motorsport, export or diagnostic use — we’ll always show you the road-legal option first.
Will it damage my engine?
Done properly — custom on your own ECU, calibrated, with your original file saved — no. A cheap generic file can. We never flash a random database file.
Which cars do you cover?
Most modern diesels (VW, Audi, BMW, Mercedes, Ford, Opel and more) and many petrol cars. Send us your make, model and year and we’ll confirm.
Do you use generic files from the internet?
Never. Every solution is developed on your own ECU file with master tools, and your original is always saved so it can be put back.
Emissions solutions are intended for off-road, motorsport, export or diagnostic use. For road use, emissions systems must remain functional.
