Validated and checksum-corrected
Detect the ECU
The ECU family is identified automatically from the uploaded file.
Apply AdBlue off
The validated SCR/DEF off module is applied; pair with NOx handling and DTC removal.
Correct checksums
Checksums are recalculated automatically so the file is accepted by the ECU.
Off-road notice: emission-related modifications are intended for off-road, motorsport or competition use only. Disabling emission equipment on a road vehicle is illegal in most countries. Compliance with local law is the user's responsibility.
AdBlue / SCR off — frequently asked questions
What is AdBlue / SCR off?
AdBlue off disables the SCR (Selective Catalytic Reduction) / DEF dosing strategy in the ECU calibration. Map Decoder applies it automatically and corrects the checksums.
Is the AdBlue off automatic?
Yes. Map Decoder detects the ECU, applies the validated AdBlue/SCR off module and corrects the checksum, producing a ready-to-flash MapPack.
Is AdBlue off legal?
Disabling emission equipment is illegal for road use in most countries. These modules are intended for off-road, motorsport or competition use only, and compliance with local law is the user's responsibility.
What about NOx and DTCs?
AdBlue off is usually combined with NOx handling and DTC removal so related fault codes do not appear. Map Decoder can package these together.
Combine with DPF, EGR and DTC removal
