This is probably a dumb question but if someone was to buy a used XCAL 2 flashed back to stock I know you can use it for another car. My question is I am being told you can get the down load software off SCT website. How do you get the actual tune do you have to buy it off someone or where do you get it. How do you data log crap. I have asked in another area on here and Pmed wayne but never get my questions answered. I just want to know how do I get this thing to work if I buy it.
