Cobb V3 Accessport - Porsche 911 Carrera / S / GTS (991.2)

Cobb Tuning

  • $ 1,895.00

Warning! Installation of this Accessport over anything other than OEM or COBB software may result in ECU/TCU failure. 


The Porsche 911 models come with an incredibly sophisticated ECU from the factory, working with these units requires an intimate knowledge of engine dynamics and software engineering to be able to properly understand and modify the functionality.

EQT has decades of experience in both fields and our shop 911 Carrera 4S has allowed us to perform R&D to deliver the best results possible. 

The in-cabin mountable Accessport V3 has a large, full color, high resolution screen which allows you to monitor up to six parameters in real time. Fully customizable from the look (multiple bezel colors), layout (set up a race, street or dyno gauge cluster) and mounting options (choose from 1,000s of standard vehicle mounts). Of course, all of the great COBB tuning is included - with enough space for 100 calibrations. This is your new Accessport - and maybe the last one you'll ever need.

Using Cobb's ProTuner software, we have dedicated hours of in house dyno testing, drivability road testing, and track torture testing into the development of our calibrations. This ensures you can be confident your car will perform optimally while retaining excellent drivability characteristics and a healthy margin of safety built into every tune.
