Exhaust and fuelling checked
Catalyst, sensors, mixture, ignition, leaks and DTCs should explain the request before calibration.

Calibration adjustment for catalyst-related monitoring on supported ECUs. Check hardware condition and legal requirements before use.
Professional service scope
Catalyst, sensors, mixture, ignition, leaks and DTCs should explain the request before calibration.
Only monitoring logic compatible with the exact ECU software is handled.
Catalyst-related modification may be illegal for public-road use and never substitutes for mechanical repair.
Catalyst-monitoring calibration support for specifically identified petrol or diesel ECU software after the physical exhaust system and related sensors have been professionally assessed.
The original binary, ECU family and software version are matched against a verified catalyst-related strategy. Similar filenames or ECU labels are not accepted as proof of compatibility.
The uploaded binary and software identifiers determine compatibility.
Unverified matches are never presented as an automatic solution.
Unsupported files can continue through the central support workflow.
Provide the complete exhaust configuration, catalyst and sensor condition, fuel-control data, all DTCs and the intended authorised use. Diagnose mixture, ignition, fuelling, lambda and exhaust-leak faults before processing.
Catalyst-related calibration changes can be illegal on public-road vehicles and do not repair fuelling, misfire, sensor or exhaust faults. The workshop is responsible for emissions compliance and post-programming validation.
