Accesport

The COBB Accessport is the most widely used ECU tuning solution for the WRX, acting as a handheld device that allows users to flash preloaded (“OTS”) maps or custom tunes directly to the car. For the 2022+ VB WRX, it enables significant gains in drivability, throttle response, and power when paired with proper supporting mods. COBB’s OTS maps provide a safe, entry-level upgrade for common setups (intake, catback), while custom protunes or e-tunes unlock the full potential of the platform. The device also functions as a real-time gauge cluster, data logger, code reader/clearer, and diagnostic tool. For most WRX owners, the Accessport is the foundation of any performance build—especially once modifying intake, fueling, or exhaust components beyond a catback.
