Dont know if its a common problem, but I have tested three different tachs
in my BJ8 and they all have the problem with showing more and more the
longer you drive.
>From the beginning they show around correct rpm, after a while to much.
Always thought it had something to do with the electronics in the tach being
cold or hot.

Subject: [Healeys] Tach heat sensitive?
I've noticed that when I drive to work in the morning when it's cool
(50-60F), my tach shows about 2500 RPM at 65 MPH. When I return home at
night when it's warm (80+ F), my tach shows about 3000 RPM at 65 MPH.
Any ideas about what's going on?
thanks,
Tom
