I'm trying to adjust my speedo but whenever I try to enter "Program Vehicle" it tells me "no index file found". Do I NEED a tune? I bought this from someone about 6 months ago and Livewire tells me that it's unlocked and never used.

Any idea?

I'm not a XCal expert, but I believe that you may have to get it set up for the particular ECM series in your car. I know that I was asked for the number on the side of the ECM when I ordered my XCal. In any case, good luck and I hope you get it figured out.
