COBB Accessport V3 – with PDK Flashing – Porsche 991 (991.1/991.2) GT3/GT3 RS

Unlock the full performance potential of your Porsche 911 GT3 or GT3 RS (991.1 / 991.2) with the COBB Accessport V3. This in-cabin mountable tuning solution features a large, full-colour, high-resolution screen that lets you monitor up to six parameters in real time. Fully customisable with multiple bezel colours, display layouts (race, street, or dyno gauge cluster), and mounting options (compatible with thousands of standard vehicle mounts). With space for up to 100 calibrations, this is your new Accessport—and possibly the last one you’ll ever need.

⚠️ IMPORTANT WARNING!
Installation of this Accessport over anything other than OEM or COBB software may result in ECU/TCU failure. Please contact COBB Support before installation.

Why Choose the Accessport V3?
The Accessport V3 is the world’s best-selling and most flexible ECU upgrade solution for Porsche. Unlock hidden power by replacing conservative factory settings with more aggressive calibrations. Upgrade forever with off-the-shelf (OTS) calibrations for most bolt-on modifications.

The Porsche PDK transmission is arguably the finest OEM street car transmission available—but that doesn’t mean it can’t be improved. The optional PDK upgrade allows you to apply enhanced calibrations to both the PDK and ECU, delivering quicker shifts and a more aggressive shift schedule under high throttle, while maintaining smooth and refined behaviour during daily driving.
