COBB Tuning Accessport V3 for Porsche 997.1 Turbo & GT2

The COBB Accessport V3 is the most advanced and best-selling ECU tuning upgrade for the Porsche 997.1 Turbo and GT2. Porsche’s stock ECU calibration is deliberately conservative; COBB’s OTS (off-the-shelf) maps unlock sharper throttle response, stronger midrange torque, and substantial increases in overall performance. As you upgrade your engine with bolt-on modifications, the Accessport continues to adapt—making it the last tuning solution you’ll ever need for your 997.1.

Installation is simple: download your preferred COBB map, plug the Accessport into the OBD2 port, and flash the ECU in about 20 minutes. Your original factory tune is backed up, allowing you to return the vehicle to stock at any time.

Warning: Installing this Accessport over any software other than OEM or COBB may cause ECU/TCU failure. Contact COBB Support with any questions.

Available OTS Maps

Stage 1: For stock engine, stock airbox, and stock exhaust.
Stage 2: For high-flow exhaust and catalytic converters with an otherwise stock engine.
Stage 3 1000: For high-flow exhaust, upgraded intercoolers, and COBB 1000cc injectors.
Stage 3 1300: For high-flow exhaust, upgraded intercoolers, and COBB 1300cc injectors.

All Stage maps enable a two-second brake-boost function, allowing boost to build while holding the brake pedal. The sport button over-boost timer is also extended to 30 seconds. Additional features include valet mode (4,000 RPM limit) and an anti-theft mode that prevents the engine from starting.

The Accessport V3 features a large high-resolution full-color display, customizable gauge layouts, multiple bezel options, and support for up to 100 calibrations. Whether you’re setting up a race, street, or dyno gauge cluster, the Accessport gives you complete control over your 997.1’s performance.
