COBB Accessport V3 – Porsche 992 GT3

Introducing the ultimate tuning solution for your Porsche 992 GT3. The COBB Accessport V3 offers simple ECU flashing combined with a powerful gauge package. Featuring a large, full-colour, high-resolution screen, you can monitor up to six parameters in real time. Fully customisable with multiple bezel colours, display layouts (race, street, or dyno gauge clusters), and mounting options (compatible with thousands of standard vehicle mounts). With increased processing power, memory, and storage, the Accessport flashes faster and stores all your maps and logs. This is your new Accessport—and possibly the last one you’ll ever need.

Note: ECU unlocking is required before the Accessport can communicate. ECUs must be shipped to COBB Tuning for unlocking.

⚠️ 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.
