I guess this post is primarily for those who have ditched their OEM factory brake controller and have installed a P3 brake controller. I'm hoping someone can answer a question for me RE the P3 brake controller. I have a 2014 3500 6.4 hemi. I am not to impressed with the factory brake controller on any of the settings, i.e. light elec, heavy elec...etc. I pull a 32' toy hauler loaded at it's heavest in 12,300 lbs. I know I'm pretty much at my max towing but for what I do and where I'm at the 6.4 does well. I know my oem controller is working, but is set at 10 and will not lock up the brakes. I have read where this is common with the oem controllers but it's certainly not what I'm used to. I also recently read where the OEM factory controller will put out less volts to the trailer brakes at slower speeds making a slow stop on a down hill grade less effective (almost pushing the truck). When I pinch the manual bars on the controller without stepping on the brakes on flat ground going 15 mph, the trailer brakes will engage and the truck will come to a slow stop. I have not gone to an empty parking lot and tried an emergency stop to see how the brakes react, which maybe I should before changing anything. In any case, here's my question. If I unplug my factory brake controller plug from the factory brake controller and plug in the P3 with the wire harness adapter, will I have to get the computer module reflashed now because the computer will no longer see the oem brake controller or will I start seeing indicator lights on the dash. I'm not much of a computer tech guy or electric guy so using the alfaobd myself would not be a good thing for me. Thanks for any info you can provide. Have a safe 4th of July.
