KESS3 Protocols Releases
Work with a full 360° approach thanks to complete powertrain management.
16.01.2026 — Upgrade 2.77
Completing the support dedicated to engine management, BOOT mode support is now also available for the Kefico CPBISH2.24.1 TCU, installed on Hyundai and Kia 1.0 MPI vehicles from 2017 onwards with automatic transmission.
This update allows direct access to the SH72544 microprocessor, providing full control over read and write operations and enabling consistent, integrated management of both engine and transmission.
Working on ECU and TCU with the same level of access means greater precision, more targeted interventions, and a complete overview of the powertrain—particularly valuable on compact yet technologically advanced vehicles.
