Harvey.

What you both are deducing here sounds about right to me.

So explain the following for me please.

If I want to change the final drive in my VTD, I am presuming I have to fit a rear 4.444 diff say. To match this in the front I'm presuming I will have to change one of the pinions in the front diff to give the same 4.444 output ratio, so that the front and back axles are matched.

Assuming I am correct so far, and knowing the front and rear sensors are both inside the gearbox, then I would deduce that both sensors are "seeing" equivalent revolutions, and therefore would send matched speed signals to the TCU.

However I would expect the clock to be reading fast by a big percentage in this case. To make the clock [speedo] read correctly I imagine it would be necessary to give the TCU a new constant for multiplying out the speed.

Do you think this would be correct for the VTD?
