Tekonsha P3 model differences.

Shane,
I have one already but are having problems and am chasing all the leads I can find.

The one I have has this feature, not one I care about though.

It is also classified as a "HEAVY DUTY" controller, not sure what that means either.

I thought they meant heavy duty wire but that is not mentioned any where either.

So what problems are you having?
Should've mentioned this in the original post

Scandal,
Fair question.
But I did not want to confuse my question. At this point I am trying to clarify the difference in the products being advertised.

From what I can gather there there is no difference.

My problem is that when coming to a stop the braking is very jerky unless I set the brake controller down very low (3.6v and no boost).

I think this is a bit low based on my previous experience with them.

I have a new car and a new brake controller but the van has not changed.

I have had the brakes on the van checked by the caravan people and they reckon they are OK. They also believe I should use boost of 2 and a higher setting and that the jerky stopping is acceptable. I did not notice this when towing with my previous car where I had it set to 6.3v and boost of 1.

I must admit I suspected the van brakes but they have been checked as said before.

I am concentrating on the controller because it is the new component and should be the easiest to verify, I thought. So I am grasping at straws at the moment to see if there is anything wrong.

If I can verify the controller and the car braking is OK I will take the van to a brake specialist and get them to look more closely at the brakes, the drums may need machining.

I have raised this question on jerky braking before on the site and got some advice but as said this post was to help clarify/verify the controller side.

AHHH, well, I also have a P3, they MUST be mounted a certain way or the inbuilt gyro will be all wrong.
The P3's are not supposed to have any side tilt, you can lift the face up or down to a certain degree, but no side tilt
Some brake controllers can be mounted on any angle but the P3 can't
I've found that with my 1.4ton camper on it needs to be on a high setting, for the brakes to balance up with my Landcruiser.

Yep the P3 can vary in the vertical but as you say not the horizontal.

Mine seems OK, may be not perfect but very close.

Most people do have a higher setting than what I have to use.
