Supported solutions

What Map Decoder can do on an EDC16U31 file

Every operation below is backed by a stored, verified modification for EDC16U31. Nothing is listed that the software cannot actually perform on this ECU.

DPF Off

Removes diesel particulate filter regeneration and monitoring logic from EDC16U31 files.

EGR Off

Disables exhaust gas recirculation control in EDC16U31 calibrations, including the related fault reporting.

Lambda / O2

Disables lambda / O2 sensor monitoring in EDC16U31 without breaking fuelling.

Stage 1

Software-only performance calibration for EDC16U31, with the supporting limiter changes.

Throttle Valve (TVA)

Disables throttle valve actuator control and monitoring in EDC16U31.

How it works

Map detection and patch generation for EDC16U31

Map detection

Upload an original EDC16U31 read. Map Decoder locates the relevant calibration tables automatically instead of relying on a fixed address list, so files from different software versions are handled.

Patch generation

A stored modification is only offered when it fits your binary. Region similarity and anchor signatures are checked against the uploaded file first, so a change learned on one software version is never blindly written to another.

Checksum correction

Checksums covering the regions a patch touches are recalculated as part of patch generation, so the ECU accepts the modified flash.

DTC

EDC16U31 DTC codes

Map Decoder holds 693 diagnostic trouble codes for the EDC16U31. Each entry stores the address and the byte values measured on a real file.

FAQ

Bosch EDC16U31 — frequently asked questions

What is the Bosch EDC16U31?

The EDC16U31 is an engine control unit produced by Bosch, part of the EDC16 generation. It is used in Audi, Porsche, Seat, Skoda and VW vehicles.

Can Map Decoder identify maps in EDC16U31 files?

Yes. Upload an original read and the relevant calibration tables are located automatically. The result is verified against the binary before any patch is offered, so a mismatched file is rejected rather than silently patched.

Which operations are supported for the Bosch EDC16U31?

Validated operations for this ECU: DPF Off, EGR Off, Lambda / O2, Stage 1 and Throttle Valve (TVA). They come from 40 stored modifications learned on real files.

Does Map Decoder support DTC removal on the EDC16U31?

Yes. 693 diagnostic trouble codes are mapped for this ECU, each with the address and the byte values measured on a real file rather than a guessed constant.

Does Map Decoder correct the checksum after patching an EDC16U31 file?

Yes. Checksums covering the regions a patch changes are recalculated during patch generation, so the modified file is accepted by the ECU.

Work on Bosch EDC16U31 files

Map Decoder analyses Bosch EDC16U31 files, detects the maps and generates a verified patch with the checksum corrected.
