Accessport V3 ECU Upgrade

The Cobb Tuning Accessport V3 is the world's best-selling, most flexible, and easiest-to-use ECU upgrade solution for your Subaru Ascent. It allows you to unlock hidden power by replacing conservative factory settings with more aggressive calibrations. You can follow a staged upgrade path with pre-loaded Off-The-Shelf (OTS) maps or utilize custom mapping for any modification level, making it a comprehensive engine management solution. This version features a larger, full-color, higher-resolution screen that can monitor up to six parameters in real time. It's fully customizable in appearance with interchangeable faceplates and offers flexible layout options for gauge clusters (race, street, or dyno). Increased processing power, memory, and storage enable faster flashing and more map/log storage. Advanced features include Launch Control for maximizing performance off the line and Flat Foot Shifting to maintain boost between gears. It also supports CAN Gateway / Flex Fuel with an optional upgrade. This Accessport is compatible with USDM vehicles only. It is designed for 2022-2024 Subaru WRX models. The manufacturer warns that installing this Accessport over anything other than OEM or COBB software may result in ECU/TCU failure.
