Brake Controller

Found the recent discussion very helpful. I have a 2009 3665re, pulled by a 2013 Silverado crew cab Duramax with 6 speed Allison. Where should my gain be set ?

I set my gain at 6.0, the on a gravel surface, using the slide bar, try and lock the brakes on gravel moving at 10 to 15 mph. If the brakes don't lock, adjust the gain up in 1 volt steps until they lock.

Thanks, I a new to this and only had gain @ 2.5

Yup, that's too low.
