The powerful tool to use in your quest for maximizing the potential of your Forester. The AccessPORT allows you the ability to upload pre-programmed maps to the Engine Control Unit (ECU) via the diagnosis port located below your steering wheel.

No Soldering
No Wiring
No Downtime

Stay up-to-date with the latest map revisions or find maps best suited for your modifications by simply downloading them from the Internet into your AccessPORT. The AccessPORT can easily grow and adapt with your needs.

Designed with convenience and functionality in mind, the AccessPORT is packed with the following features:

Ability to use AccessECU maps without removing ECU
10 Instantly Switchable Maps
Read and Clear Check Engine Lights
Download new maps via the Internet
Revert back to Stock programming

Due to limitations within the ECU's flash memory, one can only successfully reprogram it approximately 100 times. In response to this challenge, COBB's engineers developed a LIMITLESS Map Switching system. This means you can switch between maps as often as you like quickly, easily, and without ever reducing the life of your ECU's flash memory.

Up to 10 different maps can be stored on the AccessPORT for Instant Map Switching. Some examples of these maps are:

Staged Performance Maps
Valet Mode
Race Mode
Economy Mode
Anti-Theft Mode
The possibilities are truly endless!

No Comparison
Direct reprogramming of the factory engine management system allows for unparalleled control and precision of tuning. Unlike "piggyback" systems that intercept the signals coming and going from the ECU, the AccessPORT is not limited by the parameters of the stock factory programming.

The AccessECU Technology
The AccessPORT relies on the powerful AccessECU technology to perform the task of reprogramming the factory ECU for high performance applications. By fully reverse engineering the factory ECU in-house, we are able to not only modify all the fuel, ignition timing, and boost maps but also re-engineer critical parts of the software for improved performance and consistency. Our unsurpassed understanding of the factory ECU allows us unlimited control and creativity to provide you the very best ECU programming available.
