COBB Tuning Accessport V3 for Porsche 991.2 Turbo / Turbo S

The COBB Accessport V3 is the most advanced and best-selling ECU tuning upgrade for the Porsche 991.2 Turbo and Turbo S. Porsche’s factory ECU mapping is intentionally conservative; COBB’s aggressive OTS (off-the-shelf) calibrations release sharper throttle response, increased boost, and significant gains in horsepower and torque. As you add bolt-on upgrades, the Accessport enhances your setup with updated maps—making it the last tuning tool your 991.2 will ever need.

Flashing is simple: download your preferred COBB maps, plug the Accessport into the OBD2 port, and update the ECU in about 20 minutes. The device backs up your original Porsche factory tune, allowing you to return the vehicle to stock at any time.

Warning: Installing an Accessport over non-OEM or non-COBB software may cause ECU/TCU failure. Contact COBB Support with any questions.

Available OTS Maps

• Stage 1: For stock engine configuration, stock airbox, and stock exhaust.
• Stage 2: For high-flow exhaust and catalytic converters; retains stock airbox and filter.
• Stage 3: For high-flow exhaust, upgraded intercoolers, and a performance intake.

Each stage includes an optional 100-octane performance map for track days or maximum straight-line acceleration.

The Accessport V3 features a large full-color display capable of monitoring up to six parameters at once. Customize bezel colors, gauge layouts for street, track, or dyno use, and choose from multiple mounting options. With room for 100 calibrations, it’s the complete engine management solution for your 991.2 Turbo.
