Our BMW & MINI TCU (Transmission Control Unit) software upgrade, delivered via the OBD port, is designed to significantly enhance the performance and responsiveness of your automatic gearbox. By refining the factory calibration, we unlock a more intuitive and aggressive shifting profile that complements engine tuning and improves overall vehicle dynamics. Built with reliability in mind, this software ensures your transmission can handle increased power while maintaining smooth operation.

To ensure the highest quality of service and correct adaptation of the gearbox, this software is installed by our experts. We provide a full health check prior to installation.
This OBD-based TCU software is compatible with a wide range of modern BMW and MINI models equipped with automatic transmissions.
