I'm good with the mechanical stuff, but the electronics are kinda new to me.
Maybe this was addressed in the manual and I missed it, but here goes.

When you change your tire size (or other custom settings) in the Evolution, do you have to do it again whenever you switch power levels, or does it save that adjustment through all three power levels?

Basically, I run level 1 all the time, and 2 when towing, but change back and forth frequently, and would like to not have to adjust that every time if possible. Thanks

 

I'm pretty sure that whenever you set a custom setting, its for just that level. So you would have to change it everytime, check at their forum just to make sure.
