Alright I'll be waiting. Thanks man.

I still advise you to call trail tech and see if they can get you one or sell you one. I run a 130/70-17 and my setting is at 2109mm. I checked the gps today and when i was going 45 it read 41, so its off by a little but im sure i can fix it by tweaking the mm wheel size up or down on the settings.

To clarify, you find the circumference of the tire in inches and multiply it by 25.4 to get the size in mm? I'm confused as to why my tire is only a bit smaller than yours and yet there's a 400mm difference.
