COBB Tuning Accessport V3 for Porsche 997.2 GT3 & GT3 RS

The COBB Accessport V3 is the most advanced and flexible ECU tuning upgrade available for the Porsche 997.2 GT3 and GT3 RS. Porsche’s factory calibration is intentionally conservative—COBB’s OTS (off-the-shelf) maps unlock sharper throttle response, improved midrange torque, and increased performance throughout the rev range. The Accessport grows with your build and supports the most common bolt-on modifications, making it the last tuning device your GT3 will ever need.

Installation is simple: download your maps from COBB, connect the Accessport through the OBD2 port, and flash the ECU in about 20 minutes. Your factory tune is safely backed up so you can revert to stock anytime.

Warning: Installing this Accessport over anything other than OEM or COBB software may result in ECU/TCU failure.

Stage 1 Maps

Stage 1 calibrations are designed for a stock engine configuration. Left-foot braking is enabled, and the rev limiter is raised to 8,650 RPM across all Stage 1 maps. An ACN91 map is included for Arizona/California fuel formulations. Valet mode limits RPM to 4,000, while anti-theft mode prevents the engine from starting.

The Accessport V3 features a large full-color high-resolution display, customizable gauge layouts, multiple bezel options, and support for over 100 calibrations. It’s your new Accessport—and the last tuning device your Porsche will ever need.
