[BMWCSRegistry] FW: 5 speed conversions - speedometers

[David Baker]

A long time ago I put a Whitney's trip computer with cruise control in my 1972 2002.
   
  The speed sensor was a set of magnets glued and taped to the drive shaft along with a pick up bolted next to the drive shaft.  
   
  The unit had a clock.  Calibration was running the Taxi measured mile in town pressing a button at the start and end of the mile.
   
  The fuel meter plugged up, starved fuel, and had to be disconnected.  mpg reading was then in-op.

   
  It was crap but pretty much accurate and fun to play with.

up either a stereo with speed-sensitive volume, or a modern cruise
control, both of which operate off of the standard VSS signal that
drives modern electronic speedos, but doesn't exist on our old cars.
This addresses the opposite problem.

I think you will need to install a VSS signal generator first, then
connect this box! Analog/Digital/Analog?

As I recall, either Bosch or Blaupunkt makes an aftermarket VSS device.

While kicking around 5 speed conversions and speedometers, this
interesting item came to light:
http://www.abbott-tach.com/cablex.htm
It is a mechanical speedometer drive that can be driven/controlled by an
electrical pulse signal, which can be taken off the driveshaft or c/v
shaft in our case. The ratio is adjustable, so it should even be
possible to have an accurate speedometer!
It opens up a lot of possibilities as far as donor transmissions, but it
looks like "lab quality" and somewhat pricey.

Does anyone know a less sophisticated and accordingly priced system?
Maybe something in the "aircraft surplus" genre?
