Delphi ECU coverage in Map Decoder
- Supported ECU models
- 11
- ECU families
- 2
- Distinct solutions
- 12
- Mapped DTC codes
- 6,249
Map Decoder holds map definitions and measured file data for 11 control units from Delphi. 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 Delphi ECUs
AdBlue / SCR Off
Turns off the SCR / AdBlue dosing strategy and its countdown logic in Delphi ECUs.
Additive (Eolys) Off
Disables the fuel additive (Eolys) system and its level monitoring in Delphi ECUs.
Catalyst Off
Disables catalyst efficiency monitoring in Delphi ECUs.
DPF Off
Removes diesel particulate filter regeneration and monitoring logic from Delphi ECUs files.
EGR Off
Disables exhaust gas recirculation control in Delphi ECUs calibrations, including the related fault reporting.
Intake Flaps Off
Disables intake flap control and the related diagnostics in Delphi ECUs.
Lambda / O2
Disables lambda / O2 sensor monitoring in Delphi ECUs without breaking fuelling.
MAF Off
Removes mass air flow sensor dependency and its diagnostics from Delphi ECUs.
NOx Off
Disables NOx sensor monitoring and the associated fault paths in Delphi ECUs.
Speed Limiter (VMAX) Off
Removes the top speed limiter from Delphi ECUs.
Stage 1
Software-only performance calibration for Delphi ECUs, with the supporting limiter changes.
Throttle Valve (TVA)
Disables throttle valve actuator control and monitoring in Delphi ECUs.
Delphi ECU tuning — frequently asked questions
Which Delphi ECUs does Map Decoder support?
11 control units from Delphi are covered, grouped into CRD and DCM.
What operations are available on Delphi ECUs?
Across supported models: AdBlue / SCR Off, Additive (Eolys) Off, Catalyst Off, DPF Off, EGR Off, Intake Flaps Off, Lambda / O2, MAF Off, NOx Off, Speed Limiter (VMAX) Off, Stage 1 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 Delphi checksums?
Yes. Checksum correction for the regions a patch changes is applied automatically as part of patch generation.
Tune Delphi ECUs
Map Decoder analyses Delphi ECU files, detects the maps and generates a verified patch with the checksum corrected.
