COBB Tuning Accessport V3 for Porsche 981
The COBB Accessport V3 is the most powerful and flexible ECU tuning upgrade available for the Porsche 981 Cayman and Boxster. Porsche’s factory ECU calibration is intentionally conservative, leaving unrealized horsepower and torque on the table. COBB’s OTS (off-the-shelf) maps unlock sharper throttle response, broader midrange torque, and more top-end power across the rev range.
As you continue to modify your 981, the Accessport grows with your build—supporting performance upgrades such as high-flow intakes, plenums, and larger throttle bodies. It truly is the last engine management device your 981 will ever need.
Setup takes about 20 minutes: download your preferred COBB maps, connect the Accessport to the OBD2 port, flash the ECU, and enjoy an immediate transformation. Your original factory map is automatically backed up, allowing you to return to stock whenever you choose.
Available OTS Maps:
Stage 1 maps are designed for a stock engine configuration. Stage 2 maps support high-flow intake plenums and the 82mm throttle body—both of which produce a tuning upgrade you can feel from the driver’s seat.
The Accessport V3 features a large, full-color, high-resolution display; customizable multi-gauge layouts; numerous mounting options; and enough memory for up to 100 calibrations. This is your new Accessport—and the last tuning tool your Porsche will ever need.
Warning: Installing the Accessport over anything other than OEM or COBB software may result in ECU/TCU failure.
