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!

    Great Handheld Tuner

    Posted by Milic on 2nd Dec 2019

    First off the tuner is very easy to use. Also, the gains seem minimal but what it doesn't tell you is how much better your Cayenne will drive after FabSpeed tunes it. The 958 series like mine has a lot of throttle lag and lack of throttle response. Also the laggy transmission shifts in 1-2-3. FabSpeed cleans all of that up and makes the car drive like it should (well at least they made mine right!). Their process is awesome, you fill out a questionnaire and let them know what it is you don't like about your OEM tune and what you're looking to get corrected. So rather than just a "canned tune", you're getting something specific to the resolution you're looking for. Also the ability to have your stock file and tuned file is awesome for the ones that are still under warranty. In my honest opinion, the car will probably break on the stock file before it will on the tuned file. My Cayenne couldn't be happier after some FabSpeed love!
