Requires no tools or mechanical knowledge to install. The AccessPORT does all the work of programming the factory ECU for you, just simply plug it into the factory service diagnosis port located below the steering wheel. Follow the on-screen instructions and within 10 minutes you'll be out driving, enjoying your new found performance.
In order to improve the already sizable performance of the STI, our engineers have spent hundreds of hours researching the factory Engine Computer (ECU) programming and testing changes on our All-Wheel Drive chassis dynos.
Our goal is simple: to provide the optimal balance of performance, driveability, engine response, and reliability.
The AccessPORT, the core component in Stage 1, enables you with the freedom to continue the quest for additional performance if you desire in the future. As other engine modifications are made, the AccessPORT will grow and adapt to your needs helping you extract the most from your STI. Click here to read more about the AccessPORT.
In addition to improved performance, the AccessPORT also has additional features allowing you to put the vehicle into special modes such as: Max Fuel Economy, Valet, or Security.
