All true and correct.....If we were all scientists and into electrickery diagnostictrickery no one would trust anything that was published on here...
As there is no definitive answer to the specs its up to the enthusiast to come to some sort of consensus...LR and those that refurbish VCU's(and this goes for other components too) would never give away the secret of the 'elixir' that they covet.
Forums don't need science they need practical solutions.....A data base of VCU specs may have been of benefit but the starting point would be the forums and chat rooms as to 'when something' is dead or about to die...The layman/enthusiast requires that info first........
There is actually official VCU test data available. However it is well beyond the equipment of average owner mechanic/ tinkerer to perform correctly.
I'm going from memory here but I reasonably sure that the figures are as follows.
The VCU should produce 390 to 440 Nm of torque if one end is held still, whilst the other is rotated at 75 Rpm. However this requires a lathe of over 5Hp and torque measuring device to carry out the test.
The OWUT doesn't "load" up the VCU, but does tests for general degradation of the fluid.
