COBB Tuning Accessport V3 for Porsche 991.1 Turbo & Turbo S

The COBB Accessport V3 is the most powerful and versatile ECU tuning upgrade for the Porsche 991.1 Turbo and Turbo S. Porsche’s factory calibration is intentionally conservative, leaving significant power on the table. COBB’s OTS (off-the-shelf) maps unlock sharper throttle response, stronger midrange torque, and dramatically improved acceleration. Whether bone-stock or lightly modified, this Accessport evolves with your build—making it the last tuning device you'll ever need.

Setup takes only minutes: download your preferred COBB maps, connect the Accessport to your OBD2 port, and flash the ECU in about 20 minutes. Your original factory tune is safely backed up, allowing you to revert to stock at any time.

COBB OTS Maps

Stage 1: For stock engine, stock intake, and stock exhaust.
Stage 2: For high-flow exhaust and catalytic converters with stock intake hardware.
Stage 3: For high-flow exhaust, upgraded intercoolers, and performance intake systems.

All stages include an optional 100-octane performance map for maximum power during track days or spirited street driving.

The Accessport V3 features a large high-resolution color display, customizable multi-gauge layouts, and support for up to 100 calibration files. Choose from multiple mounting options and bezel styles to create your perfect cockpit setup.

Warning: Installing the Accessport over non-OEM or non-COBB software may result in ECU or TCU failure.
