Validated and checksum-corrected
Detect the ECU
The diesel ECU family is identified automatically from the uploaded file.
Apply DPF off
The validated DPF off module is applied; pair it with EGR/AdBlue off and DTC removal as needed.
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. Removing or disabling emission equipment on a road vehicle is illegal in most countries. Compliance with local law is the user's responsibility.
DPF off — frequently asked questions
What is DPF off?
DPF off is a modification that disables the diesel particulate filter logic in the ECU calibration. Map Decoder applies it automatically and corrects the checksums.
Is the DPF off automatic?
Yes. Map Decoder detects the ECU, applies the validated DPF off module and corrects the checksum, producing a ready-to-flash MapPack.
Is DPF off legal?
Removing or 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.
Which ECUs are supported?
Bosch, Continental, Delphi, Siemens, Denso and Valeo diesel ECUs, across families including EDC16, EDC17, MD1 and SID.
Need DPF, EGR and AdBlue together?
Combine emission modules in a single MapPack.
