BENCH mode for AC Delco E92: GM V8 large SUVs and Pick-Ups.

The development path on AC Delco control units concludes with this release dedicated to high-performance platforms.

06.02.2026 — Upgrade 2.87

Already supported in OBD and BOOT communication, the AC Delco E92 ECUs are now manageable through direct access without opening the unit, thanks to BENCH mode.

An update designed to simplify operations and increase safety when working on large-displacement vehicles — true icons of the American and international market. The 6.2-liter V8 engines from 2015 onwards represent some of the most powerful and complex configurations within the GM group.

With BENCH mode, you gain full control over sports sedans, premium SUVs, and high-value pick-ups for daily workshop operations. An evolution that further strengthens technical coverage across GM platforms, including the high-end segment.
