Tekonsha P3 any good with "Hensley bump"?
My revered Jordan 2020 brake controller has just gone out. Since Jordan controllers aren't around any more, I was thinking of going to another, true proportional controller such as Brakesmart or the M...

Have had the P2 for years, and yes it's very effective at eliminating the "bump". In addition to the gain/power setting, there are 3 "boost modes" that allow the trailer brakes to lead the truck brakes. The higher the boost mode, the faster the trailer brakes activate.
Remember that electric brake controllers are activated by the brake lights, and in most trucks the slightest pressure on the brake pedal turns on the lights well before pedal travel begins to apply braking force on the truck. Rather than wait for the inertia sensor to sense deceleration to apply the trailer brakes, the P2/3 applies brakes immediately when it gets a signal from the switch.
I keep my boost setting on 2 and it does an excellent job of eliminating the bump under all conditions. Enjoy the P3 it's a great choice with the Hensley.
