New BENCH protocol for AC Delco E39: high-performance GM platforms.

UPGRADE 2.82

The first step expands BENCH support on E39 units, ECUs already manageable via OBD and BOOT, now also accessible without opening the control unit, with direct access to ECU data.

An update designed to make workshop operations faster and safer: BENCH communication allows reading and writing the ECU directly from the connector, reducing working time and simplifying intervention on high-performance vehicles.

The result is full engine management control on iconic models from the US and international markets, with reliable and repeatable procedures even on vehicles designed for sporty or premium use.

A concrete first step to extend GM technical coverage and turn it into new operational opportunities for workshops.
