Each brand controller has different methods of setup, but there is a basic method. There are two items to set, aggressiveness and total braking firmness. Aggressiveness is when the electric brakes activate, they should begin to slow the trailer either exactly at the same time as the tow vehicle brakes or just slightly sooner; firmness is whether you feel the trailer slowing the tow vehicle, you feel the trailer pushing the tow vehicle, or both slow at the same time.
The electric brakes should be properly adjusted before attempting controller adjustment!
I want the trailer brakes to activate at the same time as the tow vehicle and to feel both stopping as one unit, neither one exerting force on the other.
This is best done on a gravel/unpaved road (~25mph). I Adjust the controller for aggressiveness first, then firmness. I adjust the controller so that the trailer brakes don't lock-up on the unpaved surface but any more adjustment would.
I hope this is explained logically.
