Fabspeed Porsche 957 Cayenne S / GTS XperTune Performance Software (2008-2010) FS.POR.957V8.ET

Achieve maximum power gains and drivability without sacrificing reliability. Easily flash your Cayenne S / GTS with a Fabspeed ECU Tune utilizing the included MyGenius handheld device. Fabspeed Motorsport offers an alternative tuning method for vehicles equipped with ECUs that traditionally required bench flashing. No longer do you need to remove your Cayenne's ECU and mail it in for a tune. The MyGenius device interfaces with the OBD-II port on your Porsche and your computer to complete the tuning process, which is as follows:

Tuning Process

1. Read Stock Data: Connect the MyGenius device to your vehicle via the OBD-II port and read the stock data.
2. Interface with Software: Connect the MyGenius to your PC/Windows computer (Mac OS not supported) and send the data to Fabspeed Motorsport via email.
3. Receive Custom Tune: Fabspeed uses your data and vehicle information to create a custom tune. The tune is emailed back to you within 1-2 business days.
4. Flash ECU Tune: Write the Fabspeed ECU Tune to your MyGenius, then to the vehicle using the MyGenius device.
5. Return to Stock Anytime: Easily revert to the stock tune using the MyGenius device and reflash to the Fabspeed ECU Tune as needed.
