FAQ

Catalyst Off — frequently asked questions

Which ECUs support Catalyst Off?

71 control units currently have a stored, verified Catalyst Off modification, across ACDelco, Bosch, Continental, Delphi, Denso, Siemens and Valeo.

How does Map Decoder apply Catalyst Off?

The modification was learned by comparing an original and a modified file. Before it is offered, the uploaded binary is checked against the stored anchors and region fingerprint, so it is only written when it actually fits.

Is the checksum corrected afterwards?

Yes. Checksums covering the changed regions are recalculated as part of patch generation.

Map Decoder analyses your ECU files, detects the maps and generates a verified patch with the checksum corrected.
