FAQ

MAF Off — frequently asked questions

Which ECUs support MAF Off?

108 control units currently have a stored, verified MAF Off modification, across ACDelco, Bosch, Continental, Delco, Delphi, Denso, Marelli, Siemens and Transtron.

How does Map Decoder apply MAF 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.
