I'm not sure but I didn't want to chance it. I thought that maybe the circuit used a different ratio to calculate the speed but if you took two side by side and figured that the mph match their kmph couterparts at the same locations then it couldn't hurt.

New problem...Maybe it was just me but I actually couldn't take off the face..Maybe it was just me but I couldn't for the life of me figure out how to take the needle out without breaking everything
