To properly set up the Curt Discovery brake controller part # C84VV you first need to set the max output setting with the thumbwheel (number 2 in picture) on top of the controller. You want to adjust this to a setting that when you slide the manual override lever (number 4) all the way grabs the brakes as hard as possible right before locking up.

Once that's set the next setting is the sync setting (lever on side number 3) which controls how fast the brake pressure ramps up to full pressure. If you want to reach maximum power output faster, move the switch forward. To get smoother braking action, slide the switch backward, thus supplying power to the trailer brakes more gradually. You can alter the sync setting to suit your driving preferences or to improve handling based on changing road conditions or varied trailer loads. Since yours currently feels really touchy this is probably the setting that needs to be lowered to smooth that out.

I also attached a link to the install instructions for you to check out as well.
