KESS3 Protocols Releases
The development path on AC Delco ECUs continues with a new release dedicated to the E82 units.
02.02.2026 – Upgrade 2.85
Already manageable in OBD and BOOT modes, the E82 ECUs are now also accessible in BENCH mode, allowing direct operations without opening the control unit.
An evolution designed to make workshop operations even faster, safer, and repeatable — especially on the widely used and still current 3.6-liter V6 engines, particularly across the US market from 2016 onwards.
The introduction of BENCH mode expands intervention possibilities on modern GM sedans, SUVs, and sports cars, offering a complete solution for everyday work on mid-to-high range vehicles with reliable procedures.
Another concrete step in strengthening GM technical coverage.
