tachometer accuracy
Just how accurate are the mazda orinal equpment tachometers? +-3% +-5%? Cause if you can safely rev to 8500rpm on steel apex seals, if your tach happens to be reading 5% on the high side, and you decide to take it to 8000, you are really at 8400! Sounds a little dangerous to me. Are these gauges accurate at high rpm? I dont wanna have to go put and buy an ugly, gigantic autometer tach (no offence to those who have them) just to make sure I'm not over revving wthout knowing it.

Realistically you couldn't. The circuit board behind the guage pod covers the entire back of the cluster, there would be no way to replace the tach in the stock location.

you could do it.. it would just take a little work getting the two wires that you need to go through one of the holes in the circut board.. once i get around to doing it, i will let you know.

that i do not know.. possible that it would have to stick out a little. but even that should not look that bad, since it is in the stock location...
guess i will find out when ever i get around to getting a new tac

Lol... its not an exact science you know... You might rev to 9500rpm someday with no obvious damage to your engine. You could also just as easily blow up your motor on a 6000rpm rip...

If it makes you feel any better, the tach doesn't go that high anyway... even if the tach was accurate, once you go past about 8200rpm you're flying blind anyway.
