Correct me if wrong - the ITR LSD is 1 way yeah , so it cannot engage
with no load on it. IE turning it by hand cannot "engage" it and turn both wheels at the same time
Yeh, its one way.
And yes I have tried it on my ITR with stock LSD up on the jack. Spin one wheel, the other does not turn.
As we have discussed its the type of LSD that determines how it acts.
