Achieve maximum power gains and driveability without sacrificing reliability. Easily flash your Cayenne with a Fabspeed ECU Tune utilizing the included handheld device.                                           

Fabspeed Motorsport offers an alternative tuning method for vehicles equipped with ECU's that traditionally required bench flashing. No longer do you need to remove your Cayenne's ECU and mail it in for a tune. The Handheld device interfaces with the OBD-II port on your Porsche and your computer to complete the tuning process, which is as follows:

  1. Read stock data on vehicle via OBD-II port with Handheld

  2. Interface Handheld with software on your computer and send in data to Fabspeed Motorsport via email

  3. We use this data along with information you provide about your vehicle to write a tune for your specific setup and email back your custom tune in 1-2 business days

  4. Write the Fabspeed ECU Tune to your Handheld, then to the vehicle with the Handheld

  5. Enjoy your increased performance!

No need to send your ECU in to return to stock - simply use the Handheld to flash back, then to your Fabspeed ECU Tune again at any point!
