FAQ

Seat ECU tuning — frequently asked questions

Which ECUs are used in Seat vehicles?

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

What can Map Decoder do on a Seat file?

Across Seat 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 Seat 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 Seat ECU files

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