Solutions available across MD1
The list below is the union of what is supported somewhere in this family. Open a model to see exactly which of these apply to it.
AdBlue / SCR Off
Turns off the SCR / AdBlue dosing strategy and its countdown logic in MD1.
Additive (Eolys) Off
Disables the fuel additive (Eolys) system and its level monitoring in MD1.
Catalyst Off
Disables catalyst efficiency monitoring in MD1.
DPF Off
Removes diesel particulate filter regeneration and monitoring logic from MD1 files.
EGR Off
Disables exhaust gas recirculation control in MD1 calibrations, including the related fault reporting.
Lambda / O2
Disables lambda / O2 sensor monitoring in MD1 without breaking fuelling.
MAF Off
Removes mass air flow sensor dependency and its diagnostics from MD1.
NOx Off
Disables NOx sensor monitoring and the associated fault paths in MD1.
Speed Limiter (VMAX) Off
Removes the top speed limiter from MD1.
Stage 1
Software-only performance calibration for MD1, with the supporting limiter changes.

What can Map Decoder do on an MD1 file?
Across the family the validated operations are AdBlue / SCR Off, Additive (Eolys) Off, Catalyst Off, DPF Off, EGR Off, Lambda / O2, MAF Off, NOx Off, Speed Limiter (VMAX) Off, Stage 1, Start-Stop Off and Throttle Valve (TVA). Availability differs per model — the ECU page lists exactly what is supported for that model.
Does Map Decoder correct MD1 checksums?
Yes. Checksums for the regions a patch changes are recalculated automatically during patch generation.
How many DTC codes are mapped for MD1?
13,192 distinct diagnostic trouble codes are stored across the family, each with an address and byte values measured on real files.
Tune Bosch MD1 files
Map Decoder analyses Bosch MD1 files, detects the maps and generates a verified patch with the checksum corrected.
