No shit! That story deserves it's own thread man!

it doesnt matter dont worry they cant void your warranty because of that that is why they put a rev limiter on it.....they should have put it lower...does anyone remember the 1996 mustang belt shredder problems.....they would throw belts at high rpm...

Although, they print this in big, bold font in their owners manual, so you do know what you're getting yourself into.

Are you really 100% sure about that? I mean it's a bloody Porsche, you drive it to red line, the shift gears. Where's the limiter?

Boy howdy, I sure wouldn't pay to own a Sports car that the first time I took and revved it to the red line, went for a quick shift and maybe bounced off the limiter it voided my warranty. Obviously, I don't know about someone sitting there with there foot to the firewall waiting for it to explode, that's different.

Seriously. If you hit the rev limiter on any engine you shouldn't be driving.

The rev limiter is not there for your convenience, it's there to keep the engine from blowing up due to whatever stupid thing the driver did (down shift to too low of a gear at too fast a speed, not upshift fast enough, floor the gas in neutral, you know, stuff people who know how to drive a performance car properly would not do).

This is not the old days when engine technology was so primitive that the "rev limiter" was the maximum air and fuel your carburator could feed the intake manifold. Today, if it were not for computer cotrolled limiters, a fool could hold the gas down or shift wrong and BOOM! Good bye engine.

Rev limiter won't really help you if you downshift into too low a gear. At that point the wheels>driveshaft>tranny>engine are mechanically going to force the engine RPMs to whatever they would mathematically be.

And I've never heard of a BCM that stores endless amounts of continuous driving data. I've only heard of the OBD system, which takes snapshots/freeze frame of data when an error code is set, and the airbag data recording system which records maybe 5 seconds of data just before airbag deployment. If GM can just plug a Tech II in and read your top speed or peak RPM ever reached, then that's new to the Camaro.

So now what, your just gunnna leave it. Did they not have a reason for the miles or anything? I know onstar* records your driving, it says it in the manual for reference I can obtain the information for you from the manual. I pulled the info below and have page numbers to referance from the owners manual you can call onstar and most hopefully obtain all the information of the past few days or the past 125 miles since the dealership had it. That really blows though, I bet the dealership is scared crapless of you, haha. You are one tough cookie to just throw the keys at em and take your plates off whilst leaving. I hope you get your car back and the dealership pays for their unnacceptable usage of the car.

Average Vehicle Speed

The Average Vehicle Speed display
shows the average speed of the
vehicle in miles per hour (mph)
or kilometers per hour (km/h).
This average is calculated based on
the various vehicle speeds recorded
since the last reset of this value.
The average speed can be reset by
pressing the SET button while the
Average Vehicle Speed display is
showing.

4-28 Instruments and Controls

How OnStar Service Works

The OnStar system can record
and transmit vehicle information.
This information is automatically
sent to an OnStar Call Center when
the OnStar button is pressed, the
emergency button is pressed,
or if the airbags or AACN system
deploy. This information usually
includes the vehicle’s GPS location
and, in the event of a crash,
additional information regarding
the crash that the vehicle was
involved in (e.g. the direction from
which the vehicle was hit). When the
Virtual Advisor feature of OnStar
Hands-Free Calling is used,
the vehicle also sends OnStar the
vehicle’s GPS location so they
can provide services where

it is located.

If the rev limiter was set up the same way as the Porsche you describe, I'd agree with you but GM erred on the side of caution. Also, your point about "shouldn't be driving" if you hit it does not take into acount those who power shift a car when racing which is what I do. RPM's drop in between gears for most cautios racers. RPM's rise in between gears for power shifter. This must be done so that the RPMm falls into optimum speed for the next gear.

Jewelz thanks for the info .Repaint sucks on the car, the miles on the car was the last straw.

Someone with better search-fu than I might be able to find it.

i thought that box only recorded laST 5 seconds. constantly buffers and records. throttle position, seat belt on or not, brake applied or not, vehicle speed, yaw rate? cant remember it all.

thats correct from everything i looked into

man if you guys are worried about blowing one up by missing a shift, you need to come see what we have to do for the cash for clunkers program. we drain the oil, pour half a gallon of sodium silicate (liquid glass) into the crankcase and run them till they stop! you would die if you saw how long a few have run with no oil or oil pressure!
