The latest FLEX update expands support for BMW Group vehicles with the introduction of Bench programming for the Bosch MG1CS003 ECU.

Equipped with an SPC5777M processor, the Bosch MG1CS003 control unit can now be programmed directly in Bench mode, no need to open the ECU or perform the unlock procedure via Boot Glitch.

This new Flex solution simplifies the ECU programming workflow: fewer steps, no ECU opening, and a faster, safer procedure.
