Choose options
This Accessport allows you to tune both the Engine and Transmission Control Units in your supported Porsche 987.2 Cayman, Boxster, or 997.2 Carrera. Throw away your gauges! The in-cabin mountable Accessport V3 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 storage 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) maps for most bolt-on modifications.
Peak gains are measured as the difference between the highest points of the two plots. Largest gains are measured as the largest gain at any single point between the two plots. Results may vary.
