Porsche 991.2 Carrera and GTS COBB tuning image

The COBB Accessport V3 is the most powerful and flexible ECU tuning solution for the Porsche 991.2 Carrera, Carrera S, and Carrera GTS. Unlock significant power and torque hidden by the factory calibration with COBB’s proven OTS (off-the-shelf) maps. As you add bolt-on performance upgrades, the Accessport grows with your build—making it the last tuning device you'll ever need for your 991.2.

Installation is quick and simple: download your chosen COBB maps, plug the Accessport into the OBD2 port, and flash the ECU in about 20 minutes. Your original Porsche factory tune is backed up so you can revert to stock at any time.

Warning: Installing this Accessport over anything other than OEM or COBB software may cause ECU/TCU failure. Contact COBB Support if you have questions.

Available OTS Maps

Stage 1: For stock engine, stock airbox, and stock exhaust.
Stage 2: For high-flow exhaust and catalytic converters; stock intake and intercoolers.
Stage 3: For high-flow exhaust, upgraded intercoolers, and performance intakes.

Each stage includes an optional 100-octane map for maximum performance on track or spirited street driving.

The Accessport V3 features a large full-color screen with customizable gauge layouts and the ability to monitor up to six parameters in real time. Choose your preferred faceplate, configure race, street, or dyno gauge clusters, and store up to 100 calibration files. It’s the ultimate tuning tool for your 991.2.
