I have to agree... USALS works so well with the Ultra and the
SM3D12 motor it's silly not to use it. And you have the latest firmware that fixed the bugs early on with Ultra and USALS.
You must have accurate latitude & longitude to enter into the setup screen in the ultra, the more accurate the better... if you know someone with a GPS unit you can get almost "on the dot" (within a few feet) numbers.
Good luck.
