Re: Torsen + EDL

Slip angle to a torsen is the same as torque.  Slip angle to EDL?  What's the
difference.  To the computer, the rear driveshaft is spinning faster than the
front, so does EDL interpret that as the rears with more traction and slow the
front (IMO), or does EDL interpret that as slip angle? How's it do the latter?
I suppose we could put accelerometers in the equation,  maybe someone could
explain how those would differentiate between slip and turning.  

With four drive wheels, slip angle becomes significant front to rear.  A
variable.  To a torsen, EDL, in a fwd/rwd Slip angle is a constant.  Why?
Because the drive wheels where the torsen sits, will ALWAYS have the same slip
angle, by definition.  By the same definition of a torsen center, as soon as
you turn, slip angle to the torsen becomes a variable.  INTERPRETED as a
traction.  That's the problem.  4 Wheel EDL doesn't change that.
