Out on a deserted country highway
around 7:30 am I bounced into my rev-limiter. Thing is, the needle did not appear to reach red-line.
I re-tested, keeping my eye only on the tach needle....same thing.
I knew that the tach needle would continue to slide up a bit after
my foot eased off the gas...so I watched to see how high it would go. I got bounced anytime the tach
needle passed 6000 more than a little...what appears to be 6300.
If I backed off
the gas around 5900 under hard acceleration the needle would
continue to scoot up to about 6100 or 6200
but, thankfully, no rev-limiter bounce. All this happened in first
gear, but I repeated it several times to make sure I was seeing what I thought I saw. I don't know
if I CAN shift at redline in first, at least not in this car.
I did take it steadily up to red-line once (not hard acceleration) to watch the needle carefully...still got bounced without touching redline. Comments anyone?

You don't need to redline the tach when you are accellerating hard. By that point you aren't really accelerating that much faster. It is better to shift and use the next gear. The reasoning behind this is that if you look at the hp and torque curves, you will see that at that rpm they drop right off.

Besides... It isn't all that good to redline your engine like that.<img src=/images/forums/snitz/thumbup.gif width=25 height=18 border=0>

Hey cotton. I know I've seen it before, but where could I find a nice plot of the 2.0s tourque and hp?

check out any dyno for a tibby.

For maximum acceleration, you should take it all the way to redline, if you shift before 6500, you drop down to about 125 (torque), if you keep at it till 6500, you are at about 130 (HP)

Also, the rev limiter should be at 6750. The end of redline being 6500. Sounds like your tach is reading a tad low.

Yeah, maybe the tach doesn't correspond with reality. Whatever the reason, my car encounters the rev-limiter when the tach needle goes much above six grand. Edmunds
test driver also noted that the '01
Elantra hit the rev-limiter "at 6250". I just adapted and started shifting a little past (what the tach says) is 6000. So far so good,
but I would like to know how high the rpms REALLY are when it bounces.<img src=/images/forums/snitz/uhh.gif width=15 height=15 border=0>

The cause of the problem is most likely due to your previous driving. If you haven't had any high rpm driving previous to this, your computer probably didn't have that area of your tach mapped out properly. By continuing after the initial problem, you gave it a chance to catch up to your habits. Not a problem your should worry about, but, if you plan to do any racing, and your normal driving habits are sedate, make sure you have several, high rpm shifts before you make it to the track. You have to let your car know how you want to drive.

Thanks for the comment, and welcome
SLOOPJohn. No, my normal driving habits aren't sedate<img src=/images/forums/snitz/wink.gif width=15 height=15 border=0>...far from
it actually. I'm a high-reving kinda
driver, with occasional moments of sedate motoring. But, I still hit the rev-limiter in a little stop-light get-away today...in second around 6200 or so. This occured after after previous high revs around 6000. Maybe the computer
will eventually get the range right if I take it toward red-line regularly...we'll see<img src=/images/forums/snitz/thumbup.gif width=25 height=18 border=0>

First, thanks for the welcome. I'm a refuge of FXtreme.

If you normaly, or even occasionly, drive in the upper rpm range, your computer should already have that mapped out.

Have you had your battery disconected latley? This could reset it.

If not, then you may want to take it to the dealer and have them look at it. Especially if it's still under warrenty. Your car should not be doing this.
