Validated and checksum-corrected
Detect the ECU
The ECU family is identified automatically from the uploaded file.
Apply EGR off
The validated EGR off module is applied; combine with DPF/AdBlue off 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.
EGR off — frequently asked questions
What is EGR off?
EGR off disables the exhaust gas recirculation strategy in the ECU calibration. Map Decoder applies it automatically and corrects the checksums.
Is the EGR off automatic?
Yes. Map Decoder detects the ECU, applies the validated EGR off module and corrects the checksum, producing a ready-to-flash MapPack.
Is EGR 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.
Can I combine EGR off with DPF and AdBlue off?
Yes. Emission modules can be combined into a single MapPack, with DTC removal to prevent related fault codes.
