Where is the RPM warning buzzer, so i can take it our, or if there is a way to just "turn it off", its really annoying. thx

 

Really? I kinda like it myself. Lets me know that I am around the redline without having to stare at the tach.

If you disable it, you will lose all your warning buzzers.

 

It's supposed to be annoying, it's a warning buzzer. If you change gear when you're supposed to, you won't hear it for more than a few tenths of a second anyway. It lets you keep your eyes on the road, and it also warns of low coolant and low oil, so removing it is not recommended.

 

Isn't there a way to adjust the tach within a small range if the buzzer's coming on early/ late?

 

Yeah, but unless you have the proper equipment (a signal generator and a 12V bench supply) there's no way to know what rpm you've set it to. So you need to remove the cluster, adjust the trim-pot, reinstall the cluster, test drive and find it's still not right, remove, adjust, reinstall, test drive, remove, adjust, reinstall, test drive...

An instrument specialist or repairer could probably do it pretty quickly.
