Xirdecoder ECU Chip tuning software released a new software version v3.4 on April 23rd, 2026.
What’s new in this version?
With the v3.4 update, we have delivered a faster and more powerful performance improvement. In addition, we are proud to announce support for many new ECU types.
Additionally, since program updates are handled automatically on the server side, we will continue delivering updates as usual without requiring any manual update from users.
This update has been released primarily to introduce a new feature and to provide general improvements.
With this version, you can now perform speed limit removal operations for the Citroen EVPT VCU3000 ECU type.
In addition, we have published the new ecu information for which the protocols have been activated.
We would like to sincerely thank all our users for their support and contributions.
