Fabspeed XperTune ECU Software for Porsche 991 Turbo (2013–2016)

This is the XperTune handheld software service for the first 991-generation Turbo and Turbo S, with the 3.8-litre twin-turbo flat-six. Carrera files and 991.2 Turbo files are separate applications. Check the engine generation and existing modifications so the programming request describes the car that will actually receive the software.

Technical Details

• Use reference FS.POR.991T.ET for the specified 2013–2016 application; verify model year and generation.
• The handheld communicates with a supported control unit at the diagnostic port, handling the original read and replacement write.
• Windows PC access is needed to move files between the interface and the calibration service; macOS is not supported.
• Include the completed information form and original ECU file, with fuel and hardware details.
• The tool remains paired to its vehicle and can restore the saved stock calibration. Confirm the ECU can be accessed before ordering.
