Porsche 911 Turbo (997.1) & GT2 Accessport V3
The Cobb V3 Accessport for the 997.1 is the most effective and easy to use ECU upgrade solution for your Porsche 911. Unlock hidden power by replacing the conservative factory tune with a custom Pro Etune to get the most out of your Cobb AP or use one of the FREE Cobb OTS maps. Those looking for BIG power can follow our staged upgrade path complete with turbo kits, engine packages, and Tunes to support 600-2000HP. We highly recommend all 911’s and GT2’s using the Cobb AP get a custom Etune for the best possible results.

Porsche SPECIFIC FEATURES:
Brake Boosting
With a Brewed Motorsports Pro tune you now can have brake boosting enabled for 2 seconds. You will be able to floor the gas with your foot on the brake to build boost.
Chrono Sport/Overboost mode
A Factory option that increases boost for a short time period. The GT2 does not come with Sport mode and will not have the overboost function that the normal 997.1 Turbos have. With a Brewed ETune the timer for the sport button can be raised to 30 seconds so that you can enjoy the overboost feature for longer.
Cobb Accessport OTS Maps & Brewed Custom Pro Tunes
The AP comes with maps for stock cars, cat-back exhaust, high flow cats as well as Anti Theft and Valet Mode (reduced rev limit and power). Additional OTS maps may be downloaded for FREE from COBB’s website. To get the most out of your Porsche a custom Pro Etune is highly recommended. A custom Etune ensures your engine is running at peak efficiency and reliability above and beyond what the OTS maps provide. Etunes are completed through a series of calibration updates/revisions to your tune based on data logs from your car. This allows us to deliver the best possible engine calibration for every individual car and fuel type used. For those not yet familiar with data logging using the Cobb AP here is a great walk through of data logging with the Cobb AP.
