i just found out that when i hit vtec in thrid gear my tach says 6000 so my tach is 300rpm faster. is there anyway to fix that?
so if my tach read redline at 8700 thats when my engine is really at redline?

 

No, it's hitting at 5700 rpm still, it's just hard to auditorily hear the exact switchover point.

 

I think most of our tachs are off. Personally, my vtec kicks in at an indicated 6,200rpm and I can rev beyond 9000k before cutoff!!

Don't matter none, I shift at cutoff during racing anyways....

 

My cross over is dead set @ 5,700 rpm. My tach bounces @ 9,000. A friend of mine has a PY itr that bounces @ 9,200 and a friend with a NBP ITR that bounces @ 8,900. Any one know what's up with the fluctuations on the R's rev limiter?

 

I hit VTEC at somethin like 5800, and cutoff not far from 9000, id say 8900

 

rev limiter is the same on all the cars. the tachs are NOT accurate at high rpms.

Aww shucks, I thought mine was blessed from the factory. Thanks for shootin me down Dave

 

Best way to see what u are really hitting rev limit, or what your real rpm is, is to get an Apexi Rev Speed meter....im a big fan of it...its a real time tach, playback tach, rough estimate on quarter-mile, and good for use on the road course cause you can do lap times on it.

 

My stock tach is way off. Totally unreliable.

 

If it makes you feel any better, my tach bounces at an indicated 9500.

I know it's really only 9000.

You get used to it. Not such a big deal, really.
