CTSC or Clutch Issue?!

[Alittleboost]

Question Ladies/Gentlemen:

While driving my car equipped with CTSC/CT Header/CT Exhaust..I've notice the RPM reving up when I press in the clutch at higher RPM's.

I did some redline pulls last night and had to let off at 7k rpms because when shifting into a higher gear the rpms would just shot up after pressing the clutch in...is the CTSC? or is it about time to replace the clutch?



Thanks for any input.

Are you smelling the "toasted smell", typical of clutch/brake pads after doing this?

Hey, that happened to me before, twice!! but couldn't figure out what's going on. when my car is at full stop at a stop sign, I tried to take off really quick (rpm at idle, popped in first and let off the clutch), all it did was rev to 5-6 rpm but barely moved. Then I can clearly smell the clutch burning (as you said "toasted smell"), any clues whats going on?

thanks

This doesn't sound like a clutch problem - if I understand correctly it's when you disengage the clutch that the rpm increases. (i.e. the load is removed from the engine)
What kind of controller do you have on your CTSC? OEM ECM or AEM or ???

I have the ECM....yes, when I take off quickly or put moderate to heavy load on the car and press the clutch pedal down to disengage the clutch the rpms jump up...any clues?! I thought it was a weak clutch problem.

Maybe your timing is off (i.e. not coming off the gas soon enough before depressing the clutch).

This happens to me with my wife's car, which has a clutch that releases earlier (higher) than my daily driver or NSX. Ultimately it's a timing issue on my part (not the high disengagement point of her clutch) that needs attention when I've driving that car. Unless it slips while engaged it's not a clutch problem.

From what I understand all NSXs maintain a little air into the intake manifold immediately after one releases the accelerator from full-throttle. Older ones have this little diaphram thing that keeps the throttle from snapping completely shut immediately before the idle control can kick in...I think the newer ones might achieve this via the throttle-by-wire mechanism.

Try accelerating full-throttle in gear and then release accelerator without depressing the clutch. This way you can observe the car's behavior without interference of other actions (like timing of clutch disengagement). If decelleration kicks in nearly immediately...car is behaving normally and it's probably a shift timing issue. If the car accelerates or essentially coasts for a half second before decelerating...that would not be normal.
