Does anybody else have problems with setting the speedo, mine will work at times and when I say time when I change tunes, any solutions? I have tried changing the tire size etc.

Mine worked when I changed the tire size and the tune to 65hp. When it is on the 40 hp tune it didn't. I use the GPS, its always on.

Everytime you change a tune you have to change one of the settings or it will not pick-up on it. Just change the tire size (as an example) from 315 to 305 then back to 315 and then load the tune.

I did change the tire size when I switched tunes, and mine just doesn't work right in the 40hp tune. The tire size was the same as the 65 when I went to the 40, so I think it changes the setup on all tunes when it is changed on one of them.

You still have to change the settings everytime you change a tune. No matter what it says/shows.
