[DeTomaso] Speed error

[michaelsavga at gmail.com]

What is the correlation between the speed indicator and the odometer?  Given that there is only 1 cable.  I.e.  is it reasonable to assume with an 8 percent error in speed that the car the has 8 percent fewer miles on it !
(Assume the wheels were constant from day 1 for this question).   Thus is the ratio indeed 1 to 1 within the unit so any input correct would effect both the speed and odo.

Michael,

Don't forget that we're dealing with Italian instruments here.   My speedo 
reads 5 mph fast at freeway speeds and the odometer is spot-on.   Yours probably 
has a similar level of error, meaning that if you correct the speed function, 
the distance function will be compromised.

Just FYI...

Mike
