FAQ

Dacia ECU tuning — frequently asked questions

Which ECUs are used in Dacia vehicles?

Map Decoder has data for 12 control units fitted to Dacia vehicles, built by Bosch, Continental, Siemens and Valeo.

What can Map Decoder do on a Dacia file?

Across Dacia ECUs the validated operations are AdBlue / SCR 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 Dacia 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 Dacia ECU files

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