Hi all. I have an old sct x3/sf3 tuner from my 08 Mustang gt. It's locked to the mustang. If I get it unlocked, can I use it to tune my 2016 focus st? Are there "canned" tunes on it for my focus st as well? Or would I be better off just buying a Cobb accessport directly from Cobb for 500 bucks? Thanks for the replies.

The X3 hardware ceased production in 2014/2015. The last firmware update for it occurred in 2014. This was all done in favor of the X4.

You will not be able to use the X3 on your 2016. If you had an X4 you could and it would also have preloaded tune files on it.
