Optimistic speedo

Recommended Posts

The speedo on my '89 3.2 has always given a highly optimistic reading - around 10 - 20%.  

EG at an indicated 40mph, I'm only actually doing 32mph.  

You would think that this is helpful in not getting a speeding ticket!   But it can be a problem when I drive one of my other cars that don't have over optimistic speedos!! 

I know that it's highly unlikely, but there any adjustment that can be made within the speedo unit to reduce its over optimism????

Thanks guys - I'll try SilverWT's technique. - I thought I had read about it last year but for some reason, couldn't find your thread.

Cheers,

Richard

Why not ask someone in the industry such as Reap, should be able to tell you the start of the possible.
