Accessport V3 ECU Upgrade

The COBB Accessport V3 (AP3-SUB-004) is a premier ECU upgrade solution for Subaru vehicles, offering unmatched flexibility and ease of use. It allows owners to unlock significant power gains by replacing conservative factory settings with more aggressive calibrations, and supports a staged upgrade path with pre-loaded Off-The-Shelf (OTS) maps or custom mapping for any modification level. This Accessport V3 features a larger, full-color, higher-resolution screen capable of displaying up to six real-time parameters. Users can fully customize its appearance with interchangeable faceplates and configure gauge layouts for different driving scenarios like street, race, or dyno use. Its increased processing power, memory, and storage enable faster flashing and the saving of numerous maps and logs. Installation is straightforward with intuitive on-screen instructions that identify the specific vehicle and available maps. The Accessport also allows for simple uninstallation, reverting the ECU to its original state. It can read and clear engine trouble codes, helping to diagnose issues and potentially avoid dealership visits. For tuning, it supports storing up to 100 maps and offers real-time tuning capabilities, allowing map changes while the engine is running. Advanced features include adjustable idle, real-time timing adjustments (STI only), flat foot shifting, launch control, and performance measuring tools for 0-60 mph times and quarter-mile ETs. This particular Accessport is compatible with USDM vehicles and is 50-state legal with CARB Executive Orders D-660-16 and D-660-43. It is specifically designed for various Subaru Forester XT and WRX/STI models from 2014 through 2021. It's important to note that installation over any software other than OEM or COBB software may result in ECU/TCU failure, and users should consult COBB Support if they have questions regarding compatibility or installation.
