OPF / GPF Off

Removes gasoline particulate filter logic from MG1CS031 calibrations.

How it works

Map detection and patch generation for MG1CS031

Map detection

Upload an original MG1CS031 read. Map Decoder locates the relevant calibration tables automatically instead of relying on a fixed address list, so files from different software versions are handled.

Patch generation

A stored modification is only offered when it fits your binary. Region similarity and anchor signatures are checked against the uploaded file first, so a change learned on one software version is never blindly written to another.

Checksum correction

Checksums covering the regions a patch touches are recalculated as part of patch generation, so the ECU accepts the modified flash.
