Prodigy P3 Issues
I recently purchased a Prodigy P3 brake controller. After installing it, I have run into an issue about the brakes engaging on the TT. I have set the P3 to 7.5 and the boost to 2 and the type to E...

Thing to remember about the boost. It only sends 25 to 30% of power to the brakes, and it only lasts a couple seconds. It is only to help the trailer brakes get started with the TV brakes. Boost as I understand it. Has nothing to do with setting the brake power level. In fact. I set my power level, and then turned on the boost.
My brakes work fine, and as mentioned, better at speed. Remember Inertia based brake controllers, need inertia to work properly. Plus they work better after they have warmed up, a lot better.
My only problem, is sometimes I dial in too much. IF I can feel the trailer brakes come on with the pedal, I have too much. The TV, and TT should stop as one, with no jerk from the TT brakes. If I can't feel them, how do I know they are working? I have heard the tires crying when under a hard stop.
For me I don't feel that, when it does come on firm it stays that way until I get off the pedal. But you are right in one way, the more boost and faster I go, when I need to stop quickly it does do that no problem but it does not let off as I slow down. Once it comes on it stays that way, and it is true that once the brakes have warmed up it is more sensitive.
It is true the brakes stay on, if the TV is braking. But the Boost is just to help the trailer lead the truck. As I understand it. the boost comes on as soon as you hit the pedal, at 25, or 30 %. Which ever you have set.. Then the accelerometer takes over. If it "feels" the TV slowing down. It applies the needed current to match the TV. IF it does not feel the TV slowing, It releases the brakes. If it only feels a slight braking of the TV, It backs off to match. It does whatever the TV is doing
Unlike cheaper controllers. The Prodigies measure the amount of braking force needed. As you brake, and come to a stop, less braking is needed by the trailer, so the controller backs off power accordingly. So that by the time you are completely stopped, and the accelerometer no longer feels any motion. It releases the brakes. That is why there is no jerk, like with the Voyager.
