I have ATRAC which does control the brakes to each individual wheel. The system cannot control the amount of throttle going to each wheel because there is one engine throttle for the entire drivetrain, not an individual engine with it's own throttle for each wheel. The speed knob just sets a speed at which you want to go which can be set using my foot. MTS is just volume control for the brake distribution so you get that with your 44 seconds of an unrealistic test up a mountain. In the end the systems can get you stuck because they are not constant like a locker. I've demonstrated before just how you can lose momentum with the system on because you have to lose traction in order for it to work. Hit the locker and went up the same obstacle without a hiccup. It's a decent system but nowhere near a substitute for a real locker. Also don't let it trigger constantly because they system can overheat and leave you with open diffs. <---That one is in the manual you probably didn't read. This must be your first vehicle or just first 4wd vehicle. Did you roll into the dealer and say "I want that one" and just throw money out?
