COBB Tuning Accessport V3 for Porsche 997.2 Carrera S/4S/GTS/4 GTS

The COBB Accessport V3 is the world's best-selling, most flexible ECU upgrade solution for the Porsche 997.2. Unlock power and torque masked by Porsche's conservative, one-size-fits-all factory ECU tuning by choosing and downloading COBB's more aggressive calibrations and mapping. Plus, easily upgrade forever as you add future modifications to your engine with COBB's off-the-shelf (OTS) calibrations professionally designed for most of the popular bolt-on Porsche modifications. It's truly the last engine management solution you'll ever need!

Once you receive your Accessport, you just download the tuned map(s) of your choice from COBB's customer website, then upload them to your car's ECU via the OBD2 port. It's simple and easy, requiring only about 20 minutes! You can also save your original factory tune so you can change the ECU back to 100% stock anytime.


With the release of tuning support for the 997.2 Carrera S/GTS, owners are able to enjoy an increase in overall power and smoother power delivery.  The following Off The Shelf Maps are available for supported vehicles:

  • Stage 0 v101
  • Stage 1 91 v101
  • Stage 1 93 v101
  • Stage 1 100 v101

The Stage 0 OTS map is simply the factory calibration data. The Stage 1 OTS maps are intended for vehicles in an otherwise stock mechanical configuration.  An upgraded cat-back exhaust/mufflers will be fine and will not cause any issues.

Below are dyno graphs representing pulls using the included Stage 1 OTS maps for both 91 and 93 octane fuels. As you can see, both maps provide gains in power and torque across the board. The Stage 1 100 map will produce an additional 4-5 peak horsepower.

The in-cabin mountable Accessport V3 has a large, full color, higher resolution TFT screen that allows you to monitor up to six parameters in real time. Fully customizable look (multiple bezel colors and styles are available), layout (set up a race, street or dyno gauge cluster) and mounting options (choose from hundreds of standard vehicle mounts). Of course, a full range of unparalleled COBB tuning is included, with enough space for 100 calibrations! This is your new Accessport - the last tuning device you'll ever need.
