So I have a hand held SCT XCal 2 tuner for my 96 gt. I saw recently on SCT's site updates for the tuner and for the live link on a computer. It says to update the firmware on my Scanner I have to take off the tune. does anyone know if there is any chance that I might loose my saved tune? also I have 2 tunes saved on my Xcal2 - how do I know which one is the one two load when I get the Xcal2 updated?Last question. Has anyone with the new SCT LiveLink done their own car tunning? Is it easy and whats to it? Thanks
