- Mapped DTC codes
- 1,107
Map Decoder holds map definitions and measured file data for 5 control units from Valeo. 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.
Valeo ECU families
- V42 ECUs
Operations available on Valeo ECUs
Catalyst Off
Disables catalyst efficiency monitoring in Valeo ECUs.
Lambda / O2
Disables lambda / O2 sensor monitoring in Valeo ECUs without breaking fuelling.
OPF / GPF Off
Removes gasoline particulate filter logic from Valeo ECUs calibrations.
Throttle Valve (TVA)
Disables throttle valve actuator control and monitoring in Valeo ECUs.
Valeo ECU tuning — frequently asked questions
Which Valeo ECUs does Map Decoder support?
5 control units from Valeo are covered, grouped into V4.
What operations are available on Valeo ECUs?
Across supported models: Catalyst Off, Lambda / O2, OPF / GPF 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 Valeo checksums?
Yes. Checksum correction for the regions a patch changes is applied automatically as part of patch generation.
Tune Valeo ECUs
Map Decoder analyses Valeo ECU files, detects the maps and generates a verified patch with the checksum corrected.
