- 8
- Distinct solutions
- 15
- Mapped DTC codes
- 86,712
Map Decoder holds map definitions and measured file data for 142 control units from Bosch. Coverage is built from real files: each supported operation comes from a modification that was learned by comparing an original and a modified binary, then verified against the target file before it is offered.
Operations available on Bosch ECUs
AdBlue / SCR Off
Turns off the SCR / AdBlue dosing strategy and its countdown logic in Bosch ECUs.
Additive (Eolys) Off
Disables the fuel additive (Eolys) system and its level monitoring in Bosch ECUs.
Catalyst Off
Disables catalyst efficiency monitoring in Bosch ECUs.
DPF Off
Removes diesel particulate filter regeneration and monitoring logic from Bosch ECUs files.
DTC Removal
Suppresses selected diagnostic trouble codes in Bosch ECUs using addresses measured on real files.
EGR Off
Disables exhaust gas recirculation control in Bosch ECUs calibrations, including the related fault reporting.
Intake Flaps Off
Disables intake flap control and the related diagnostics in Bosch ECUs.
Lambda / O2
Disables lambda / O2 sensor monitoring in Bosch ECUs without breaking fuelling.
MAF Off
Removes mass air flow sensor dependency and its diagnostics from Bosch ECUs.
NOx Off
Disables NOx sensor monitoring and the associated fault paths in Bosch ECUs.
OPF / GPF Off
Removes gasoline particulate filter logic from Bosch ECUs calibrations.
Speed Limiter (VMAX) Off
Removes the top speed limiter from Bosch ECUs.
Stage 1
Software-only performance calibration for Bosch ECUs, with the supporting limiter changes.
Start-Stop Off
Permanently disables the automatic start-stop function in Bosch ECUs.
Throttle Valve (TVA)
Disables throttle valve actuator control and monitoring in Bosch ECUs.
Bosch ECU tuning — frequently asked questions
Which Bosch ECUs does Map Decoder support?
142 control units from Bosch are covered, grouped into EDC16, EDC17, MD1, MDG1, ME17, MED17, MEVD17 and MG1.
What operations are available on Bosch ECUs?
Across supported models: AdBlue / SCR Off, Additive (Eolys) Off, Catalyst Off, DPF Off, DTC Removal, EGR Off, Intake Flaps Off, Lambda / O2, MAF Off, NOx Off, OPF / GPF Off, Speed Limiter (VMAX) Off, Stage 1, Start-Stop Off and Throttle Valve (TVA). Availability differs per ECU and is listed on each model page.
How does Map Decoder know a patch fits my file?
Every stored modification carries anchor signatures and a region fingerprint. The uploaded binary is compared against them before a patch is offered, so a modification learned on one software version is not blindly applied to another.
Does Map Decoder handle Bosch checksums?
Yes. Checksum correction for the regions a patch changes is applied automatically as part of patch generation.
Tune Bosch ECUs
Map Decoder analyses Bosch ECU files, detects the maps and generates a verified patch with the checksum corrected.
