Fabspeed XperTune ECU Software for Porsche Cayenne V6 (957, 2008–2010)

For a 2008–2010 Cayenne with the 957-generation 3.6-litre V6, this service provides software through the XperTune handheld workflow. Begin with the vehicle identification and original ECU file. A V8, diesel or earlier 955 V6 requires a different application; the Cayenne name alone is not enough to select a calibration.

Technical Details

• Product reference: FS.POR.957V6.ET, for the naturally aspirated 3.6 V6.
• The supported control unit is accessed at the vehicle diagnostic connection for both reading and writing.
• File transfer requires a Windows PC. A Mac is not a supported substitute for this step.
• Fabspeed needs the original read and a completed information form covering the car, fuel and modifications.
• The handheld stays paired to one vehicle and retains that car’s original calibration for restoration. Confirm security/software compatibility first.
