As it happens, I've had exactly the same problem when I installed a
Lumenition electronic ignition system to my car. For reasons that are
unbeknown to me (maybe someone on the list can explain eh situation
better that I), installing a contactless electronic ignition system
seems to really screw up the behaviour of ones Tach.
What I can tell you is that I came across a fantastic article on the
Sunbeam Tiger Owners assoc. website that explains exactly how to resolve
the problem. It's copyright protected so that you can't actually save a
copy to your HD but you can print a copy off.
Go have a look at it here:

I assure you that it will help.

| I installed Pertronix Coil this weekend and it doesn't seem
|to like my stock Tach or is it the Tach doesn't like the coil.
|Anyway I figured I match the Ignitor installed last summer but
|now the Tach goes crazy at times.
| It idles fine and generally reads correctly at lower speeds.
|It also appears to function correctly through the gear shifts
|but often at around 60 or faster it tends(Tach) to bounce
|around. Anyone have any ideas?
