KESS3 Protocols Releases
Gain greater control over the most widespread Yamaha ATVs on the market.
27.04.2026 — Upgrade 3.11
The development dedicated to the ATV segment expands with the introduction of BENCH mode for Mitsubishi 2UD-8591A-00 ECUs, installed on Yamaha models with 700cc engines from 2016 onwards.
This new protocol enables direct access to the control unit, operating directly from the ECU connector, ensuring greater reliability during read and write phases and improving the precision of interventions for maintenance and performance development.
