Denso ECU coverage in Map Decoder
- Supported ECU models
- 8
- ECU families
- 1
- Distinct solutions
- 7
- Mapped DTC codes
- 2,727
Map Decoder holds map definitions and measured file data for 8 control units from Denso. 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.
Denso ECU families
- SH2 ECUs
Operations available on Denso ECUs
AdBlue / SCR Off
Turns off the SCR / AdBlue dosing strategy and its countdown logic in Denso ECUs.
Catalyst Off
Disables catalyst efficiency monitoring in Denso ECUs.
DPF Off
Removes diesel particulate filter regeneration and monitoring logic from Denso ECUs files.
EGR Off
Disables exhaust gas recirculation control in Denso ECUs calibrations, including the related fault reporting.
Lambda / O2
Disables lambda / O2 sensor monitoring in Denso ECUs without breaking fuelling.
MAF Off
Removes mass air flow sensor dependency and its diagnostics from Denso ECUs.
NOx Off
Disables NOx sensor monitoring and the associated fault paths in Denso ECUs.
Denso ECU tuning — frequently asked questions
Which Denso ECUs does Map Decoder support?
8 control units from Denso are covered, grouped into SH.
What operations are available on Denso ECUs?
Across supported models: AdBlue / SCR Off, Catalyst Off, DPF Off, EGR Off, Lambda / O2, MAF Off and NOx Off. 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 Denso checksums?
Yes. Checksum correction for the regions a patch changes is applied automatically as part of patch generation.
Tune Denso ECUs
Map Decoder analyses Denso ECU files, detects the maps and generates a verified patch with the checksum corrected.
