Default When a tach does this

I assume it's not good. Any ideas on the fix? With engine not running it's at rest at 0, when running it pegs off the scale.

most likely culprit is a bad ground associated with tach filter, or fail(ing) tach filter itself.

This is just the excuse you need to convince the wife to get the new C6. You just need to say, "Honey, the repair will be in the thousands and it just makes fiscal sense to get a new one."

Unless you have a modified ZR-1, like Jeff has...

Which makes me think Jeff, did you wind it up that high and get it stuck there?!

Not my car, it's only got a 6K tach...

It's on a 90 L98 car, don't have much experience with them.
