New development for AC Delco E39A: BENCH now available on GM group vehicles.

UPGRADE 2.83

Alongside the already available OBD and BOOT communication modes, BENCH is now introduced. An update designed to simplify daily workshop operations, especially on vehicles for the US, Australian and European markets, where 1.6 and 2.0 turbo engines still represent a significant share of the circulating fleet.

The possibility to operate without opening the ECU improves safety and repeatability, making interventions on premium and widely used mid-size vehicles more efficient.

A technical continuity that strengthens GM coverage and prepares the ground for the next releases in the series.
