Open Source Tuning: It Begins

I finally received a working Tactrix cable, the first unit I received was broken but Tactrix cross shipped me a new one right away. A little pricey at $178 but the alternative is the Cobb Access port at $700 so by comparison, not so much. The Tactrix cable is the only cable that is supported by Romraider and ECU flash, some of the opensouce tools needed to tune the Subaru. In case you didn't know, the OST software is free.
