why is a value like this given in percentage and not as an absolute value? right, because it depends on the force applied: apply 100Nm and 30% means another absolute value than if you apply 1.000Nm and take 30% from this.

so it simply makes no sense to give different percentage values. it does make sense to give two values as there is one ramp for power and one for coast. but a third ramp simply is not there!

of course the guys at diffsonline can claim anything they want to. but as long as there is no in depth explanation to this "magical behaviour", i can not believe it.

impossible! look at the way the force is applied to the clutchpacks in the gkn viscolok and look at the activition in a clutch type lsd. if someone has understood both ways of pressure generation it is clear that the above is impossible.

no, the faster response comes from the way, the pressure is applied in a clutch type lsd vs. viscolok.

so i guess i have to wait until someone will strip down his unit and is posting pics of the internals.

ok, it locks 30% on power and 90% on decel (this setup would make no sense in a FR car but it could be built, yes!).
...but in what situation will this unit lock 60%?
