Derek,

Why not some mechanical arrangement to trace lines on a wax roll ?   Shouldn't
take long to fabricate :)  I wonder what the pre-war Mercedes team used to
use...

How about taking cine film of a well stocked dash?  A calibrated beaker of
viscous liquid attached to the dash top to sense G.  A dial indicator for
throttle position on a bowden cable. A system of mirrors to see how far the SU
pistons have risen and a peak at the colour tune. A battery of manometers for
induction vacuume and key pressure points on the body.  A weather vane to sense
slip angle.  Lights for each gear.

What else did you want?  We must collectively be able to save you from
strapping a black box full of trouble and a plate of spaggetti to your
machine.  I've also copied the pre-war list as there was a thread a while back
on this topic.  They have an easier time of it as they can always have a boy
ride on the running board with a stop watch and note book peeking at the
workings.  The same technique is also useful for full power adjustments.

David
