I am desperatley looking for some guidance. I did get an Xcal2 from a friend and some custom tunes. My brother needs an Xcal for his mustang so I am looking at getting a gryphon and letting him have my Xcal2. What I really would like to find out is... can the Xcal2 tunes be rewritten for the gryphon or will they load onto the gryphon as is? They are in the .cef file extension. Many thanks for all the great work you do Bill and Corey!!
