Works like a factory controller. You have to ask the dealer to flash the computer (at least on my '19 F-150 that you built) which costs more than the controller. Towed a heavy trailer and the gain control is built in the same way as the factory controls. Excellent purchase. Don't buy more expensive versions of this product for no reason.
