Alientech’s latest upgrade, version 3.49, introduces a significant advancement for workshops: a new OBD protocol for Bosch MD1CS001 ‘Locked’ ECUs. This enhancement primarily benefits BMW and Mini vehicles equipped with 1.5L and 2.0L diesel engines from the B37 and B47 families, enabling more efficient tuning processes.

Traditionally, tuning these ECUs required a BENCH connection, but now, thanks to the KESS3 tool, mechanics can perform read and write operations directly via the OBD port after an initial unlock. This development streamlines workflow and reduces the need for physical ECU removal.

What changed in KESS3 3.49?

The KESS3 3.49 update introduces a new OBD protocol for Bosch MD1CS001 ‘Locked’ ECUs. This protocol allows for direct read and write operations via the diagnostic port after an initial unlock using a BENCH connection.

This advancement builds on existing BENCH support, providing a more seamless and efficient tuning process. Workshops can now manage ECU calibrations without repeated physical access to the ECU, thanks to the integration with Powergate for remote tuning capabilities.

Which vehicles are now supported?

The new protocol supports a range of BMW and Mini models equipped with Bosch MD1CS001 ECUs, specifically those with 1.5L and 2.0L diesel engines from the B37 and B47 families.

  • BMW: 1-Series, 2-Series, 3-Series, 4-Series, 5-Series, 6-Series, X1, X2, X3, X4
  • Mini: Cooper D, Cooper D Clubman, Cooper D Countryman, Cooper SD Clubman, Cooper SD Countryman, One D, One D Clubman, One D Countryman

Why does this matter for workshops?

This development is crucial for workshops as it simplifies the tuning process for Bosch MD1CS001 ECUs. The ability to perform read and write operations via OBD after an initial unlock reduces the time and effort required for ECU tuning.

What this means for your workshop

For Alt Tune’s file service customers, the new OBD protocol for KESS3 enhances the efficiency of ECU tuning for supported BMW and Mini models. The ability to unlock ECUs initially via BENCH and then perform subsequent operations via OBD streamlines the tuning process, saving time and resources.
