Lets take your "overtaking example".
You shift back to (lets say) 2nd when you see the gap in the opposing traffic, push the trottle to WOT and steer to the left to overtake while making left blinker blink (all in one
)
Top down of course and you miss your shifter beeper because that truck makes a lot of noise. (it uses a Richmond Final Drive
)
Now suddenly the car doesnt go any faster (rev limiter keeping revs & speed at a constant while still @ WOT trying to overtake).
Al of that ^^^ without the "hitting a brick wall" feeling.
Once you notice that the car doesn't go any faster, you, the driver, shifts to 3rd and off you go.
You merge back into your lane without any problems.
That truck driver never even noticed you took an extra 1.5 seconds to overtake.

Let me improve on your idea (I hope you don't have it patented
). Suppose we have a smart ECU that no matter how hard you press on the gas, it will not hit the rev-limiter, but it will keep the RPM just below the rev-limiter. That way, there is no need for the fuel cut-off at all. You won't have the "brick wall" feeling and there will be no bounce. Without any fuel cut-off, and with a quick up-shift, I'm sure you can over take the truck with 1.5 seconds LESS.I am now off to talk to some lawyer about this idea.

I have only had my S for a few months but have hit the limiter on at least 3 occasions. It bounces so fast that you can't really tell that the rpms are dropping. If the motor was build anything like my taurus Sho's was the limiter is around 3000 rpms less then what the motor is capable of reaching. The limiter was at 7000rpms in that car and the old yamaha motor was said to have seen more then 11000 rpms without a problem. Which is why I keep the SHO as my daily driver. 323,000 miles and going.

Rest assured, no damage to the engine will occur if you bounce off the rev limiter. When I owned my NSX and attended a national NSXPO event, Honda's NSX guru was present. There were many technical questions for him. The subject of rev limiters came up. Was told that when the NSX was tested, the car was driven in 1st gear floored with the rev limiter cutting in and out for two miles nonstop. No engine damage occurred and none was expected by the engineers. The rev limiter was doing its job. I'm sure the S2000 motor can rev at higher RPMs beyond redline but it was purposely set well beyond that for engine longevity. So bounce, bounce, bounce!

I've seen a nice new MY06 Rio around here to test that with.
No doubt it will work

I hope your lawyer was able to tell you the difference between this.
Because I can't
The time stamp will be needed in patent-court

Really?
My first reaction when hitting the rev limiter was: SHIFT!
Maybe it is time to "grow a pair" and keep @ WOT in 2nd or so.
Just to see what happens.
If you never hear from me again (some may go
) it didn't work.
