Description

The COBB Tuning Accessport V3 is the world's best-selling, most flexible, and easiest-to-use ECU upgrade solution for your Subaru. It unlocks power by replacing conservative factory settings with more aggressive calibrations, offering a staged upgrade path with pre-loaded Off The Shelf (OTS) maps or custom mapping for any modification level. The Accessport V3 features a new in-cabin mountable design with a large, full-color, higher-resolution screen capable of displaying up to six parameters in real-time. Its interface is fully customizable, allowing users to change bezel colors, set up different gauge clusters for race, street, or dyno use, and utilize a wide variety of standard vehicle mounts. Enhanced processing power, memory, and storage enable faster flashing while accommodating all your maps and logs. Key features include Launch Control for maximized performance off the line by setting a secondary RPM limit when stationary and the clutch is engaged, and Flat Foot Shifting to maintain boost between gears by keeping the accelerator fully depressed. Additionally, with the COBB CAN Gateway Flex Fuel Upgrade, it supports measuring ethanol content and sending that data to the ECU for Flex Fuel calibrations. Important notes include a warning that installation over anything other than OEM or COBB software may result in ECU/TCU failure. This Accessport is compatible with USDM vehicles only. The device comes with a preinstalled screen protector that needs to be removed before use. This part is legal for sale and use on Emissions Controlled Vehicles in all 50 states with multiple CARB Executive Order (EO) numbers listed.
