Achieve maximum power from the 2019+ Porsche Cayenne GTS / Turbo 4.0L Twin Turbo V8 engine without sacrificing driveability or reliability by optimizing the engine's performance. Performance ECU software upgrade improves horsepower, torque, and driving characteristics by reprogramming various sensor inputs, air/fuel ratios, and boost pressure (if applicable).

Not applicable on hybrid models. 

COMPATIBILITY:

• Fits Porsche E3 Cayenne GTS / Turbo 4.0L Twin Turbo V8 vehicles (2019 - June 2020) (Does NOT Fit Hybrid Models)

POWER:

• Cayenne GTS
• Stock = 420 WHP / 448 TQ
• Tuned = 600 WHP / 526 TQ

NOTES:

• This is not a physical/shipped product.  This upgrade requires you to send us your ECU for re-programming. You will be emailed a download link with detailed instructions after adding this to your cart and checking out.
• While a vehicle equipped with bolt-on upgrades will experience maximum gains as a result of the increased efficiency of the engine, great power gains can be made on a completely stock vehicle!  
• You must fill out and include a copy of the ECU Information form along with your ECU upon sending it in. Please contact us if you need to send the form in any other manner.
• Fabspeed Motorsport saves your stock/factory ECU settings so that we can convert or flash your ECU back to stock settings at any time for a small fee.
• Special requests and tune file upgrades may be subject to additional fees.
• Why the June 2020 cut-off date?. All vehicles that currently use the Bosch MEVD and MG1 family of ECU’s starting mid-June 2020 are completely locked by Bosch. The reason for the update is to provide improved security for autonomous driving and other driving assistance features and keeping hackers away from remotely intervening with the vehicle’s systems. The lock has been introduced in the bootloader of the ECU and is implemented on the processor level, which means that “bench unlocking” with direct access on the ECU is no longer possible. 

SHIPPING DETAILS:

Shipping costs for sending an ECU to Fabspeed is the responsibility of the purchaser.  The ECU will be tuned within 24-48 hours of receiving it and Fabspeed will then ship back the ECU using whatever method it was shipped in with.  (For example: If you send in your ECU via Ground shipping, we will ship it back via Ground.  If you ship it via Overnight, we will ship it back via Overnight.)
