KESS3 Protocols Releases

New protocol for EVPT VCU3000 – Citroën, Fiat, Opel/Vauxhall.

Work in BOOT mode on the new VCU units for EVs, now supported.

03.12.2025 — Upgrade 2.67

With this update you can operate directly on the memory of the EVPT VCU3000 control unit, installed on ultra-compact electric vehicles from Citroën, Fiat and Opel/Vauxhall with 5.5 kWh power units from 2025 onward.

The BOOT connection guarantees full access to the VCU data, enabling complete read and write operations for accurate parameter management and full control over your tuning workflow. A solution designed for workshops beginning to work on the new generation of micro-EVs.

Thanks to the support for Citroën Ami, Fiat Topolino and Opel/Vauxhall Rocks-e, you can expand your service offering to include electric vehicles increasingly common in urban environments, providing specialist and high-value services.
