How come there's no option to just change your tire size without tuning? The "adjustable parameters" isn't highlighted and in modified stock tune the only parameters you can adjust is trans.

Can anybody tell me how to just calibrate speedo for tire size? The only way I see how to do it is to load a tune first then it gives me the option. I don't want to load any tunes, I just want to change my tire size so the speedometer is correct.

use the modify stock tune option to change only tire size.
