Fabspeed ECU Tune (Cayenne Turbo 958)


Designed to Fit:

  • 2011 - 2014 Porsche Cayenne Turbo / Turbo S

Product Details

Achieve maximum power gains (over 99 whp & 140 ft-lbs) and drivability without sacrificing reliability. Easily flash your Cayenne with a Fabspeed ECU Tune utilizing the included MyGenius 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 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:

  1. Read stock data on vehicle via OBD-II port with MyGenius
  2. Interface MyGenius with software on your computer and send in data to Flat 6 Motorsports or Fabspeed Motorsport via email
  3. Fabspeed uses 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 MyGenius, then to the vehicle with the MyGenius
  5. Enjoy your increased performance!

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

Power Gains

The dyno chart is a comparison between a 958 Cayenne first ran with Fabspeed's Secondary Catbypass Pipes, followed by the addition of the Fabspeed ECU Tune. All testing was done on their in-house Dynojet by their experienced tuner.

  • Stock = 449 whp / 515 ft-lbs
  • Tuned = 536 whp / 620 ft-lbs
  • Peak power gains of 86 whp and 105 ft-lbs of torque
  • Maximum gains of over 99 whp and 140 ft-lbs of torque at 6000 RPM
Note - The Fabspeed ECU Tune with the Dimsport handheld requires access to a PC with internet connection and the customer sending the ECU readout prior to flashing.
