Car jerks when letting off brake

Had the same problem. Solved it. Prodigy P2 brake control. I had unknowingly pressed the BOOST BUTTON on the top of the control. That was the culprit. Reset it and no more "jerking" when releasing the brake pedal.

Which IS the exact reason I did not consider a P2 and a P3 at that time did not exist.

Too many buttons and settings that either need attending to while driving or when driving conditions change.

That is one of the biggest issues I see with pretty much all controllers that depend on your brake light to signal the controller to start braking (ALL inertial controllers use the brake light which is the same as a time based controller).

Time based AND inertial controllers REMOVE the brake output as soon as the brake lights turn off.. No ramp down, just a straight OFF.

That results in the trailer pushing you when stopped on hills, effect gets worse in stop and go traffic.. Some times you might be on/off the brake quickly in stop and go and Inertial controllers may or may not "detect" or react fast enough and the result is jerky feeling.. The BOOST setting is supposed to HIDE that feeling..

My Jordan 2020 was dead on simple, sure you had some initial "setup" to do and was not a "plug and play" device, but once you had it dialed in there was no other knobs other than the output knob, no switches or other do-dads to tinker with. That controller was smooth as silk and not once ever gave a jerky feel under slow speed, stop n go or even highway conditions.

I was a bit nervous when I bought my 2013 F250 with IBC, was not sure if it would result in just as good feel as my Jordan.. I was extremely pleased the first trip on how smooth the IBC was.. Could not tell the difference and the transition to IBC was a smooth one.

I still have the Jordans in my older vehicles, but, if I sell those vehicles they WILL be stripped of the Jordans!

Keeping them as backup just in case the IBC were to fail. You WILL have to pry the Jordans out of my cold dead hands.
