OK guys, I am new to the Active Center Differential and have some questions.
I know that it acts as an open differential with variable lock up controled by the ACD computer with 3 modes. When the emergency brake is pulled the ACD decouples the rear wheels completely leaving you with a 100/0 torque split front to rear. The other end of the spectrum would be fully locked up at 50/50 torque split.
Now before any newbies chime in that you can send have a 30/70 split or 0/100 split with a rear bias, let me just say up front that is not correct and in fact is impossible with our setup. I don't even dare ask this question on EVOm because I would have people arguing with me over that point for 10 pages and never get any useful information.
What I am wondering is how the different modes change the lock up characteristics of the ACD. I suspect that tarmac leaves you with an open diff most of the time unless it sees a reason to lock up or partially lock up the center diff, gravel is more likely to give you partial or full lockup, and snow is partially locked most of the time with full lock up part of the time. This is all speculation and I have no idea if it is close to the truth or not.
Does anyone know, or have a link to a good source of information about our setup?
Thanks,
Keith
