 The XS port is synonymous with the identity of Cobb tuning, but it isn't where we started. At first, Supermaps had to be flashed directly to an ECU on a bench outside of the car. It worked, but it was time-consuming and inconvenient. As is often the case, necessity and a bit of frustration led to innovation. In an effort to streamline the Super tuning method, Trey dreamt up the idea of accessing the OEM ECU directly via the OBD-2 port in order to flash modified ROMs to the car with a convenient handheld device that is now known as the Version 1 access port. For the first time, without the need to remove the ECU from the car, a professional tuner could connect their laptop to the ECU while on the dyno and easily make calibration adjustments in real time between pulls. And even more importantly, the average Joe could quickly change between several save maps for their engine at any time and place all with an affordable device that could fit in a glovebox. The release of the Version 1 access port completely transformed Subaru ECU tuning in North America and laid the foundation for the future of Cobb tuning.
