the infamous inaccurate tach....
so far, this is really all ive found:
now that was suppost to fix the cap that changes it from V6 to V8....
my questions are:
i really like the looks of my stock tach, and im not adding a aftermarket one to my car.... it would be nice if it was more accurate though..

It describes how to make a V6 tach work on a V8 engine.
I gave a pretty good description of where the capacitor is on the tach on this thread. https://www.thirdgen.org/techbb2/sho...hreadid=114057
Look at my second post on that thread, the first one I was a little off in the position of the capacitor.

my questions are:
- what is the part that wears out over time? is it that cap?
- is my 91 tach the same circuit as the older tachs?
- if it is a cap or resistor that wears out, can i replace it with a variable one, then use a scanner program to "tune" it to work better?

I think the capacitor might be the problem. My TV repair guy agrees for what that's worth. I have ordered one after I install it I will let you know. Cross your fingers.If it doesn't work I'll be out $.57 and we will all be a little wiser.
