Like everyone else, I've hit the rev limiter a couple time (fuel cut off), and immediately clutch and up shift. I've never stayed on to find out if it actually repeatedly "bounces" off the rev limiter rapidly ( a fast "bong..bong..bong" sound).

 

Yes, it'll "bounce".

 

All cars do that (for autos, that's assuming that the car isn't shifting up a gear for you). The fuel is cutting off repeatedly at that point.

 

Just an addendum to this:

All modern day fuel injected engines that are controlled by an ECU of some kind. The old style mechanical fuel injection had no such limiter. Of course, no carbeurated car does unless it was an aftermarket add on limiter to shut down the ignition. Most of those cars had engine driven mechanical fuel pumps.

 

I believe every car with a (electronic) rev-limiter (fuel cut-off) is designed to "bounce". I don't see any workable alternative to "bouncing" from a design engineering point of view. Fortunately, this "bounciness" is completely under the control of the driver -- if the driver does not want it to bounce, then just stop hitting the rev-limiter repeatedly.

 

Interesting...
So IF you just keep you foot down at what revs does the fuel start to flow again?
I would rather be told then try for myself

 

I don't know. Why don't you hold it down to the floor for 2 or 3 minutes and see what happens.

I think the fuel cut is at 9200 for the 2.0L. When you get to that, it shuts off. When the engine slows due to no fuel, it falls back below 9200, where it will pick up again. That's why it "bounces" - 'cause it goes back and forth. How fast it does it, depends on how much momentum the engine had going up and how much driveline resistence it takes to bring it down. So, it cuts off as it passes 9200 and it comes back on as it passes 9200.
It's not unlike you throwing an electric switch on and off. How rapidly the light flashes depends on how fast you flip the switch.
Unlike say, a home heating furnace or an automatic air compressor, there is no established difference between the upper limit where the fuel cut happens AND the lower limit where the fuel comes back on.

 

Geez, Warren. We've missed ya.

I see
One would expect a more sophisticated behaviour from a "learning" ECU the S2000 uses.
If the weather changes its allready upset
ON/OFF switches are not sophisticated IMO.

That said.. I still do not have the guts to just keep my foot down in 3rd or so.
