This ECU is the bees knees, but I don't need it anymore because I'm not using it. It was in a 2010 STI for the better part of a summer. I don't know where the original CD for the tuning software, but luckily I had Mr. Soliman at RS Motors make a copy of it. (I'll continue to look). In the meantime, you can consider this particularly awesome piece of Cosworth technology up for sale. I'm asking $2,800 because I doubt there's anyone here who can afford this thing or knows anyone who can actually tune it. It'll be going up on NASIOC soon, as well.
