my revs seem to "hang" if i shift really quickly at high rpms.

for instance... 100% throttle in 3rd... 8000rpm... clutch in/throttle off... shift to 4th... clutch out/100% throttle.

what happens is, the revs will hang at 8000 for about 1.5 - 2 seconds before dropping to ~6000 (as opposed to instantaneously dropping when clutch engaged)

- i'm NOT powershifting (keeping throttle in while clutch goes in)
- clutch doesn't seem to be fading in any other conditions (eg, i can start in 4th from a stop and the clutch doesn't slip
- if i granny shift at that rpm, the clutch acts as normal
- if i release-then-stab the gas when the revs are hanging the rpm will drop to normal.

WHAT GIVES?!?!

 

oh, btw, i've been driving stick for quite a few years, and the only time something like this has occurred, was when the clutch was fading... but even then, other signs were telling me the clutch was fading.

 

I haven't heard anything from an S, only from 06+ Si due to their ECU problem.

So maybe it could be your ECU?? Maybeee

 

i have an 02 and experienced the same thing. thought it was just normal.

 

If you're clutch isn't slipping, then your tires are.

 

I've felt that before on hard 3-4 shifts when I had the factory clutch. I'm pretty sure that is your clutch slipping.

 

Release the clutch then give it gas. Sounds like you are on the gas (or never coming fully off the gas) before the clutch has pulled the motor back down to the next gear's rpm. Would be better if the motor dropped rpm when you lifted the gas and was at the next gear's rpm when the shifter went in to that gear. Then you could drop the clutch at the correct rpm. I know on motorcycles that are running lean, they will hang the rpm with the throttle off. On the S2000, I would bet that the driver's right foot is being lazy and not coming fully off the throttle. Giving the motor just enough to stay at high rpm unloaded.

 

i'd reset the ECU and see what happens

AP1's dont have cdv's.
