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...

Hi Tery,
I used a Teckonsha P2 controller for quite a few years until I got my new truck last year. Both the P2 and P3 controllers have the "boost" feature that sends a boost to the trailer brakes before the regular settings kick in. That boost lasts for a few seconds and then tapers off to the amount of braking required by the tow vehicle. The amount of boost is set by you before using the controller. I set mine once and rarely touched it again although it is easily changed if you wish. The only time I changed it was when driving slowly through campgrounds, some city streets, etc.
In addition, the boost starts by the application of the tow vehicles stop lights. This happens before the tow vehicles brakes even start to do any stopping. This allows the Prodigy to apply trailer braking before the truck braking starts. You can easily feel this by very lightly stepping on the brakes with enough pressure to light the brake tail lights but not enough to stop the truck. You will feel the trailer brakes come on - the amount depends on the boost setting you have set up. This is something equivalent to using the hand control to apply trailer brakes.

Barney talks about the "boost feature" of the P3, which is helpful to eliminate the Hensley bump. Do other controllers (excluding the expensive ones) have this feature, or is it unique to the P2 & P3?
