IBC settings for 360IBL behind '16 Ram 2500 6.7l

Gain of 6.5 seemed to feel right to me so far, but this is my first fiver. ;)

My manual says that light electric is for trailer up to 10,000, heavy electric is for trailers over 10,000 pounds. The hydralic light and heavy read the same.

As I remember when messing with the light and heavy electric settings all it seemed to do was change the gain. If I choose light I think it set the gain at 2 or 3, heavy set the gain at 5ish. I kind of think the truck remembers where you left the gain for each of the four settings so if you tow a light trailer and use a gain of 4 then tow a heavy with a gain of say 7 all you have to do is switch from light to heavy electric and your truck will remember what gain you like.

I couldn't tell you if I have mine set on heavy or light but I do know my gain is set on 6 to 6.5 for freeway driving and I set it to 5 when driving the city streets. I like to have my brakes set tight when cruising down the road.

I would suppose you select heavy electric, but only you know if you have electric or electric over hydraulic. Then, at 20-25 mph, fully apply only trailer brake. If it locks up turn the gain down and do it again. If it doesn't lock up adjust the gain up and do it again. You're trying to set the gain such that if you cram the brakes on in an emergency the trailer brakes will lock up with the truck brakes, but only just. It really is a trial and error sort of adjustment.

When you get it set test it again a time or two. At higher speeds when you need to manually hit the trailer brakes to stop a sway or control a descent it will have a lot of brake available but not quite enough to skid.

Unless your trailer has a hydraulic brake reservoir then you have electric brakes. Electric over hydraulic is most often used on boat trailers so there is no electric components in the wheels to get wet when dunking the boat. You probably want heavy electric as your setting. If that is too much you can always set it for light electric but you are over the suggested cutoff between the two settings.

I have a 2015 Ram Megacab 2500 with the Cummings and use light electric. I just played around with the setting until I found the one that worked best all around. My tow is a 7,000 pound TT so light works for me but you may need more braking.

Yes, I'm aware of the truck setting from the manual; I typed them in my original post. :)

My questions is more around which one should I choose to start with, considering my setup, and why?

If you go to Ram website you can order the actual owner material rather than the "user guide." In the manual it will tell you of 4 settings. Electric light (under 10,000 pounds), electric over hydrolic light, heavy electric, and heavy electric over hydraulic.

My 2016 is set to light electric with gain at 7.5. That allows for lock up at 25 mph and very smooth breaking. I'm stopping a 6000 pound TT. works great.
