Is there a 'black box' to record top speed to void warranty?

[cliffy]

Most cars in North America I believe have a mandated speed limiter of 155. I know all BMW's have one, and if you take M-School drivers training they can de-activate and reset to give you some more

Maybe some of you missed where I posted about how the Pontiac dealer flat out told me exactly what speed I had done in the car a few day's earlier. And he was so correct.

In my G8.

The C6 ZR1 has the limiter at 217. The standard C6 is 195.

From what I am told it has to do with the stability at speed of the vehicle.

Sorry if this is off topic.

I believe the information stored is minimal. However, if air bags are deployed data from all systems are captured for that time frame and helps OnStar operators deploy medical teams, etc. Just imagine them calling the police and indicating its a head on collision going 55mph versus its a head on collision going 130mph. Police and medical teams would react differently.

Why would they react differently? A head on at 55mph is a very serious accident that takes lives.

a head on collision at 130MPH and the police can hit the donut shop before showing up, there will be no survivors.

ha, as morbid as this thought it, i have to agree.

the body couldnt handle that much deceleration

Its true your info is recorded and stored, if it shows you abused the car ie over revved, dumped the clutch, power braked etc the manufacturer should NOT honor the warranty. If you drive your car properly you will have no worries in regards to your warranty. Going 130 mph will NOT void your warranty but going 130 mph and down shifting into the wrong gear lunching your tranny could. The above about data being subpoened and used to prosecute wreckless drivers is true and has happened many times in many states so again drive right and no worries. If you want to haul ass take it to the track where its legal.

Anything over 95 in a 70 Chevelle, your ass is puckering a little, and for God sakes don't try to turn it at speed......LOL

I was doing 120 once in my 99 TA. Man, was it a thrill, but never do it again on street/highway. If I want to go that fast again, I will take it to the track.

Here's some anecdotal evidence for you. One of the Airmen who worked for me a few years ago got into a wreck, pretty bad. I had a chance to take a look at some of the police pictures from the scene, which included one of the analog speedometer stuck at 80. The speed limit was 35.

Kirk, I don't mean to disagree since you probably know more than I do since you work in the "speed" industry but, I don't think the C6 (ZR1, Z06 or LT) is "set" at anything. They are drag limited.

You are right about the stability thing though for most governed cars. Thats why they electronically limit the speed.

What I have learned is there is 3 ways to "limit" top speed:

Drag limited: in stock form the car simply runs out of ass. Meaning you would never be able to redline your max gear. Once you could not cut through the air any faster the car has reached max speed and will hold, even if you arent at max RPM.

Rev limited: you run out of gears. You would simple bounce off the rev limiter all day long. The car could go faster but the gearing won't let it.

Governed: electronically set for some reason or another, i.e. the Camaro, 155 (V8)


Now take my supercharged 2007 Mustang GT (I had to make it as fast as my SS somehow) Anyhow, it is a Saleen supercharged GT with many other goodies (not a saleen car). Anyhow the tune took out the governor, set to 150 or something. So the car puts +/- 480 at the wheels on a cool, dry day. So I ask the obvious question... whats this car good for top end. The tech told me the car is good for about 180 with the 5 speed BUT after 160 you will be scared shit less. The hood will flap, the rear will lift up, the car will lose it. In stock form, the body shape is not set up for those speed. My guess is the Camaro is the same story.

If you have a manual or just download the manual PDF from this site. Look on page 12-14. See below.

This vehicle has an Event Data
Recorder (EDR). The main purpose
of an EDR is to record, in certain
crash or near crash-like situations,
such as an airbag deployment
or hitting a road obstacle, data that
will assist in understanding how
a vehicle’s systems performed.
The EDR is designed to record data
related to vehicle dynamics and
safety systems for a short period
of time, typically 30 seconds or less.
The EDR in this vehicle is designed
to record such data as:
• How various systems in your
vehicle were operating
• Whether or not the driver and
passenger safety belts were
buckled/fastened
• How far, if at all, the driver was
pressing the accelerator and/or
brake pedal
• How fast the vehicle was
traveling


This data can help provide a better
understanding of the circumstances
in which crashes and injuries occur.
Important: EDR data is recorded
by your vehicle only if a non-trivial
crash situation occurs; no data
is recorded by the EDR under
normal driving conditions and no
personal data (e.g., name, gender,
age, and crash location) is
recorded. However, other parties,
such as law enforcement, could
combine the EDR data with the type
of personally identifying data
routinely acquired during a crash
investigation

If you're that worried about it, just buy an extra ECM & change it out when you take it to the dealer.

(Considering it's easy to change the Camaro's out).
