Description

The COBB Tuning Accessport v3 serves as the premier ECU upgrade solution for select Subaru models, offering unparalleled flexibility and ease of use. This device allows you to unlock your vehicle's hidden performance potential by replacing conservative factory settings with more aggressive calibrations. You can follow COBB's staged upgrade path using pre-loaded Off-The-Shelf (OTS) maps or opt for custom mapping to suit any modification level through E-Tuning. The Accessport v3 features a large, full-color, high-resolution screen capable of displaying up to six real-time vehicle parameters. It provides the ability to monitor vehicle sensor data, read and clear engine trouble codes, and measure performance metrics like 0-60 and ¼ mile times. Additionally, it includes features such as adjustable on-screen shift lights, estimations of horsepower and torque, and drag race simulation data. Included with the v3 AccessPORT are the device preloaded with OTS maps, a detachable OBDII connector, a USB cable, a soft case, a user guide, silver and black bezels, and a mount. It is also RoHS compliant, indicating a lead-free design. The Accessport v3 can be custom tuned by a network of ProTUNERS, including iA Tuning. This specific model, AP3-SUB-002, is compatible with the following USDM 2.5L turbocharged Subaru vehicles: 2004-2007 Subaru Impreza STi, 2006-2007 Subaru Impreza WRX, 2005-2006 Subaru Outback XT, 2005-2006 Subaru Legacy XT, and 2004-2006 Subaru Forester XT.
