About 2 1/2 weeks ago I sent in a black ecu with ITC to be updated from 1.0 to 2.0. It's due to be delivered to me this afternoon, so there absolutely is support , I just do not know to what extent repairs can or will be made.. I have had xfi since just after 2.0 was released. I found early on that almost no one would share tune files. You could find some info, but not much. You either had to take courses, pay a pro to tune or figure it out on your own. I figured it out on my own. In doing research 10-15 years ago, I found the situation to be similar with most of the other commercially available controllers.
