This update adds BENCH support to AC Delco E39 ECUs, already accessible via OBD and BOOT, allowing direct operation without opening the control unit.
BENCH mode lets you read and write ECU data straight from the connector, making interventions faster, safer, and more precise on high-performance vehicles.
A practical step that provides full engine management control on popular US and international models, opening new workshop opportunities.
Supported vehicles
Chevrolet Camaro, Equinox
GMC Terrain
Saab 9-5
