The Cobb Tuning AccessPORT for your WRX and STi is a handheld programmer that allows you to unlock your vehicle's hidden potential by reprogramming the stock Engine Control Unit (ECU). Performance tuning data is uploaded to the ECU via the OBD-2 diagnostic port in a matter of minutes, and requires no cutting, wiring, or other such modifications. What makes the Cobb AccessPORT Unique is its ability to change tuning data on-the-fly without having to completely reprogram the ECU. This technology allows the Cobb AccessPORT to get the most performance out of your Subaru in the least amount of time, and protects your ECU from accidental damage.

By selecting one of  the Cobb AccessPort pre-installed performance maps you can automatically optimize settings such as the air/fuel ratio, ignition timing, boost, and more for performance results you can instantly feel. Cobb Tuning AccessPort Offers you the ultimate personal tuning solution for your Subaru. It saves you time and money with the ability to conveniently reprogram your vehicle's computer (ECU) by selecting one of the pre-installed performance "maps" that automatically optimize settings such as the air/fuel ratio, ignition timing, boost and more for performance results you can instantly feel.

Cobb's Accessport Stage 1 map is designed for showroom stock cars, meaning you can boost your power and prepare for future modifications by simply plugging in the Cobb Accessport As you add upgrades like a exhaust you can download the appropriate map to get even more power from your WRX. If you already have an exhaust or other modifications, Cobb's AccessPort Stage 2 map will eliminate the check engine lights (CELs) resulting from removing the catalytic converters, and maps with lowered wastegate duty cycles are available to reduce boost spikes on 2.5L cars with the stock turbo and aftermarket exhausts. The Cobb Accessport functions as a 'chip' for users working within the guidelines of the included maps, but it can also be tuned by a Cobb Protuner, or the end user using a Cobb optional Street-Tuner software for additional modifications including bigger injectors, turbos, etc. All the while, the Cobb Accessport retains the driveability and simplicity of a stock ECU.
