Ok guys i feel absolutely stupid right now but im gonna ask this question anyway. I have had my gryphon for almost a month and I still can't find where to change my tire size and gear ratio...Where the heck is it???lol. I am so lost right now. And im technologically challenged so all the help is appreciated. lol. Sorry for the stupidity...

 

All you need to do is change your program, one screen will ask if you want to custom tune (or something like that), say yes and scrowl down thru the list of items to adjust. You'll find tire size and gear ratio there.

Hope this helps.

 

Wow I feel really stupid now.lol. Thanks for the help dude!
