[Spridgets] Torque Sensing diff or LSD

[derf]

I think Torque Sensing is a type of LSD.
I am not alone in this theory.
Mazda seem to think it is.  Options listed for Miatas include "Torsen
limited-slip rear differential."
That doesn't make me or Mazda correct.  But, as far as I'm concerned (and
many others, Wikipedia included)  LSD can mean Torsen, viscous, clutch type,
or others.
Your definition of Limited Slip Differential differs from mine.
