The infamous "break-in" period.

Also isnt Nissan VOIDING warranties in the GTR if the owner takes off the VDC during launches? Must be something in the black box

It's always possible that they're recording some small long-term critical data values, like time spent with VDC off, or time spent over XXX mph, but I don't think it's likely. They're definitely not recording every little detail over any long period. And if they are doing anything of this sort, it's probably only available to Nissan specialists with special equipment to check up on expensive warranty claims.

More likely than not, all we've got is the standard black-box functionality (which, given legal authority to do so in your state, insurance and law enforcement and everyone else can read). The norm is a rolling record of the most recent 30 seconds of all the vitals (speed, RPM, gearing, accel pedal, steering wheel angle, various VDC/brake info, brake pedal pressure, etc) which gets frozen on a critical event (like airbag deployment) for later analysis.

But of course, my post is entirely speculation, I could be wrong.

Sorry guys but there is only one way to break-in your new car.
***Drive it from the beginning the way you intend to drive it later***
Meaning: If you want a quick car, wring its neck out (within reason) from day one.
Over the last 20 years, my brother-in-law and I have owned a total of 38 cars.
17 of those have been brand new and they include Mercs, Porsches, BMWs, Jags etc.
ALL of them had been broken-in the hard way and guess what?
NONE of them have developed any problems as a result of our breaking-in process.
The way we look at it is that if you break-in your car driving like an old woman, the car will drive later like an old woman and vice versa.
My new 370z has seen the redline every day it has been driven.
This includes a redline in the first 3 gears on the way out of the dealer's yard.
I have done 130mph and on the 29th Aug, I'm tracking it with our local Porsche Club.
Stop worrying and drive your cars the way they were intended to be driven. The "Z" was intended as a sports car, so drive it like a sports car.
I am not saying to put it in first gear and sit on a redline for 10 minutes. That would be a stupidity, but there is nothing wrong in putting your pedal to the metal and changing gears as the needle touches the redline.
If you still have doubts, read the car magazines, watch Top Gear and Fifth Gear etc etc.
Do you think the cars they test are fully broken-in in accordance with the user manual?
No chance.
They've been driven by the journos from day one and they've been hammered from day one!
Have you noticed that somehow the cars they test do better 0-60 and 1/4 mile then the times the owners get?
By now you should know the answer.

Not saying your wrong. However, I've seen somewhere can't remember where, that Top Gear break a lot of cars making their shows.
