Adjusting Brake Contoller

I have a DrawTite 5504 brake controller.  Since it isn't proportional I have noticed if I lightly put on the brakes the trailer brakes will go on hard which can cause a jerking when you stop.  I have a gain control which I believe controls the amount of braking and a synch control which is a time delay for braking.  I am assuming the synch time needs to be increased?  I don't seem to have issues if I put the brakes on solidly just when I am lightly tapping them usually when approaching a stop light......I may just need to adjust my braking habits.  Anyway just wondering if anyone here has a similar controller and how they adjust them.

You'd need to check the connector style and pin out to see if it was compatible. You ought to be able to do that from the instruction manuals for the two controllers.

I am quite happy using the Tekonsha 'pod' brake controller with my r-pod...and it's a timed controller and works fine...it's dirt simple and cheap and old school and I would recommend it for someone on a budget and/or who prefers simple basic operation. With a timed controller, you can mount it in any position, including upside down with minimal clearances under the dash.

Here is the description of operation of the Tekonsha P2, which I have. The P3 and other modern proportional controllers work similarly. They use solid state accelerometers like what's in your smartphone. They are measuring accelerations on two axes so they know which way "down" is to zero out gravity. That also allows them to be mounted at any angle as long as they are facing the direction of travel. They are adjustable (Tekonsha calls it boost adjustment) so you can increase or decrease the braking action from the trailer relative to the tow vehicle. You might want to use a higher boost level if you had your water tank filled for example, or if you were on a long steep downhill grade. Other than that, once you have initially set your max braking level there is nothing to adjust, the controller will automatically apply trailer brakes in proportion to the deceleration rate you are getting by applying the tow vehicle brakes, which is what you want it to do.
