Operations available on Delco ECUs
AdBlue / SCR Off
Turns off the SCR / AdBlue dosing strategy and its countdown logic in Delco ECUs.
DPF Off
Removes diesel particulate filter regeneration and monitoring logic from Delco ECUs files.
EGR Off
Disables exhaust gas recirculation control in Delco ECUs calibrations, including the related fault reporting.
Lambda / O2
Disables lambda / O2 sensor monitoring in Delco ECUs without breaking fuelling.
MAF Off
Removes mass air flow sensor dependency and its diagnostics from Delco ECUs.
NOx Off

Delco ECU tuning — frequently asked questions
Which Delco ECUs does Map Decoder support?
1 control unit from Delco are covered.
What operations are available on Delco ECUs?
Across supported models: AdBlue / SCR 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 Delco checksums?
Yes. Checksum correction for the regions a patch changes is applied automatically as part of patch generation.
Tune Delco ECUs
Map Decoder analyses Delco ECU files, detects the maps and generates a verified patch with the checksum corrected.
