A critical point for users of the 1.2.0 base software is its limited support for Module 77 (Bosch ME9/EDC16 Bench). This specific module was developed and released in a much later update of PCMFlash and requires a newer core version to function. The version 1.2.0 executable does not contain the necessary protocols to communicate with those ECUs via the Bench protocol, regardless of what licenses are present on the key. To use Module 77, an upgrade to the official installer (version 1.3.x or later) is necessary.

Added MED17.9.7 support to Module 43 (Land Rover) and MED17.1.62 support to Module 48 (VAG UDS). Hardware Compatibility

is an integrated software solution designed for professional automotive technicians and tuners to read and write ECU (Engine Control Unit) and transmission data.
