the tunes and the software for 1.0 and 2.0 are a bit different. there were some changes to the firmware that causes the need for different parameters. Which version is your ecu for ? Which version of the software are you using on your laptop ? I just sent a XFI 1.0 box with ITC in to be upgraded to 2.0..
