I cannot fathom that a BMW would rev to the moon, well past redline on an autorev match, and I doubt a tuner would put a map in place to give it the info it needs to spin that high. Chances are, clutch came out and there's your mechanical over rev. Software ain't stopping that.
My friend thinks he shifted his s2000 at an autocross and it may have seen 13k to 14k rpm...he drove it home parked it for a few months and changed the valve springs and upgraded the retainers to AP2 retainers and the car seems to be running just fine 2 years later. He may have gotten really lucky...
The JDM integra Type R transmission with the 4.7 final drive the 3rd to 4th gear speed drop puts you in some really close situations to overrev the motor at the track, puts you in no man's land speed wise, take the risk downshifting at 75 mph close to the top of 3rd gear or ride it out in 4th.

There is no way that motor over-revved mechanically without the clutch engaging. None, zero.Originally Posted by ND40oz
Stop believing everything people tell you on the internet.
If my house burns down and you find me with a gas can and a lighter, I say I didn't do it, do you believe me? The guy posted a video of the car very clearly being mechanically over-revved. Software is not going to do that.
Good thread is good.
Driving my turd truck home this afternoon, I found myself concentrating on shifting with an emphasis on the thumb down thing SoS posted.
If you are going at a speed that causes you to run off the road before ESC can provide any assistance, you may not experience the benefits of ESC
I grenaded my motor on my M3 right after I turbo'd it. I was going through a corner wound out in 4th gear with the motor all torqued up, shifted and hit 3rd instead of 5th. Bent a bunch of valves, screwed up the cylinder wall and a bunch of other fun stuff. Cost me a solid 5k to get it back together. Also, this was a common problem.
All Hail Andy?
I don't understand how the car didn't compression lock the rear wheels and cause him to spin / crash / roll. Normally an over-rev results in compression lockup, no?
it almost sounds like someone removed the rev limiter, he no-lift-shifted, missed the gear and it revved to death. Reality is that it stayed 'revving' for a long time.
Something doesn't make sense.
