COBB Tuning Accessport V3 for Porsche 718 (All Models)

Porsche 718 Cayman and Boxster

The COBB Accessport V3 is the most advanced and best-selling ECU tuning upgrade for the Porsche 718 Boxster and Cayman. Porsche’s factory ECU mapping is conservative by design, leaving untapped power and torque on the table. COBB’s OTS (off-the-shelf) performance maps unlock sharper throttle response, increased midrange torque, and greater top-end power across the full rev range.

As you add bolt-on performance upgrades, the Accessport grows with your build—providing map support for most intakes, exhausts, intercoolers, and more. It’s the last tuning device your 718 will ever need.

Installation takes about 20 minutes: download your preferred maps from COBB, connect the Accessport to your OBD2 port, flash the ECU, and you're ready to drive. Your factory tune is safely backed up so you can revert to stock anytime.

The Accessport V3 features a large full-color high-resolution display, customizable multi-gauge layouts, and support for 100 calibrations. Choose from a wide range of mounts and bezel options to create your ideal cockpit setup.

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