Ebraking with ACD

When you yank the ebrake the ACD is supposed to disconnect does it throw the power to the rear or front wheels?

The ebrake locks the rear wheels.

just dont pull it if u dont want broken parts- and center diff means it doesnt transfer power past that so power only to the fronts

Our cars are front wheel biased, yes?

Our evos are 50/50 all the time no matter what the ACD is doing. ACD just determines how fast lock up happens.

"Despite popular belief, this switch DOES NOT change the torque split. The differential is geared at 50:50 and cannot be changed by the push of a button. What this switch actually does is quite simple. Each setting determines how long the ACD will delay in freeing the center differential after a steering input is made. In addition, it will determine how much locking force the ACD will exhibit on the clutch pack and center differential."

"The ACD is a bevel-gear type center differential with a front/rear torque distribution of 50:50"

"In short, the ACD unit hydraulically controls the limited-slip locking state of the center differential which ranges between full locked, full open, and every point in between these two states. It calculates what the optimum locking amount would be using real-time input from the previously mentioned sensors and which ACD mode is selected. The ACD is extremely fast in operation, bettering the performance of the standard VCU and Viscous units."

There is no point. But if you MUST pull the e-brake, atleast put in the clutch so it disconnects the drivetrain from the engine. And yes 50/50 all the time. There is not a bias.

Our cars are not front wheel biased. We are front wheel based.
