FAQ

Audi ECU tuning — frequently asked questions

Which ECUs are used in Audi vehicles?

Map Decoder has data for 43 control units fitted to Audi vehicles, built by Bosch, Continental, Delphi and Siemens.

What can Map Decoder do on an Audi file?

Across Audi ECUs the validated operations are AdBlue / SCR Off, Additive (Eolys) Off, Catalyst Off, DPF Off, EGR Off, Lambda / O2, MAF Off, NOx Off, OPF / GPF Off, Speed Limiter (VMAX) Off, Stage 1, Start-Stop Off and Throttle Valve (TVA). Availability depends on the exact ECU.

How do I know which ECU my Audi has?

Upload the original read — Map Decoder identifies the control unit from the binary itself, so you do not need to know the ECU part number in advance.

Work on Audi ECU files

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