FAQ

NOx Off — frequently asked questions

Which ECUs support NOx Off?

57 control units currently have a stored, verified NOx Off modification, across ACDelco, Bosch, Delco, Delphi, Denso, Marelli and Siemens.

How does Map Decoder apply NOx 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.
