Default C7 Z06 computer

It seems everyone is getting upset that the new Z06 is losing races and the timing is being pulled out at a very conservative rate, etc...

I'm sure someone will correct me if I'm wrong, but I read that GM reps are saying "just break it in". Which to me "hints" that the computer is going to be very consrvative until the break in period is over (the amount of miles GM predetermined), at which point it should no longer be an issue. Which makes sense because they are giving a 100k warranty on a 650hp motor. And from the likes of the posts I have seen, it's probably a good thing they are protecting people from themselves!!!

So I ask this question... has anyone broke in their Z06 yet and then raced? Did you then race repeatedly? Or is everyone going ***** to the wall after 100 miles...lmao!

Just food for thought...

The very first video posted showed a C7 Z06 getting beat in seven races by a Viper....and the C7 Z06 had 700 miles on the odometer.

Perhaps the predetermined mileage is something like 1,000 miles? All I'm saying is that no one even has a 1,000 miles on their car yet and they are already racing. I guess time will tell.

You see, when there are conflicts like this, along with all the other contradictory information going around, it doesn't do anything to inspire at least me. It makes me nervous. The only solution is to sit back and wait for the true performance in the field.

I agree that the manual says wait until 1,500 before tracking etc, but where does it say to NEVER go WOT before 1,500 miles, after 500 miles is reached. Isn't that what the Z06 in question did, just ran WOT for maybe 15 seconds at a time and did not run for 20 minutes hard on the track?

In fact, doesn't the tach switch over from 4,000 RPM to 6,500 RPM when the odometer reaches 500 miles. I would assume that means it is okay to go WOT after 500 miles, as most people don't drive around at 6,500 RPM without going WOT to reach that 6,500 RPM. In fact it says not to do full throttle(AKA WOT) starts under 500 miles, not 1,500 miles.

Seems to me that the owner of the Z06 didn't violate the owners manual by going WOT for around 15 seconds with 700 Miles on the odometer.

I don't think the WOT for 15 seconds is the problem, it says not to participate in a track events, the difference being obvious because there will be multiple/continuos WOT and hard braking involved. Perhaps the continous or multiple WOT pulls alerts the computer it is a track type event? We can only speculate as to what the program looks for during this first 1500 miles.
In the end it's an awesome car and who cares what it can and can't beat? There will always be someone faster out there. So unless you're trying to win a world championship or something, enjoy owning a track capable car that isn't just fast in a straight line.
Months to a year from now, after all the mags and online testing is done, and they are no longer new, this will no longer be an issue in anyones mind. I think people are too impatient. In due time the true potential will come out.

Not as of yet. Only time and a larger sample size will tell. Either-way, the car is awesome!

Its not a matter of beating somebody. Its not a matter of what some stupid video shows. Its a matter of being told the car is the most high performance Corvette ever made yet the implications now are something else. If you buy it for the track but have to park it and not participate at the track, what good is it? Going to park it at the track on display as an example of a shiny new toy that can't perform?

GM's testing on the track showed it was faster than a ZR1. Once again....PATIENCE! Soon many people will have more than 1500 miles on their car, and Car and Driver and others testing will begin. Lets see what happens then, too soon to judge or make that conclusion!

It would really, really help if Tadge (sp?) or some one else at GM with gravitas would step forward and just TELL US! Many wouldn't believe him either but me and a good number would. Into an information void goes unending speculation....rrm

I can’t confirm this but the ECU may have several gates to cross before it considers the car broken in. We know there is certainly one at 500 miles because the tachometer caution bar moves from 3500 to 6500 when the car reaches 500 miles. I suspect but can’t prove there are at least 1 maybe 2 other gates. If they exist at all these other gates are based on engine operating hours not car mileage. Even if so, I doubt the " break in tune" is significantly different from the normal tune. At best you might see 2-3% power increase in the first 5000 miles from the tune adjusting to the engine physically breaking in.
At least thats about what we have seen in other GM cars over the years.

You make a point here sir. We aren’t sure how the ECU selects or enables certain features. Therefore we really don’t know how it is set up to "protect" the engine when new. For example with the C7 A8 the computers in the car share gobs of information. This information has parameters that when met assumes you are on a track and allows the car transmission to go into its most aggressive shift algorithms. As far as I know there is no way to tell you have achieved this mode. So it stands to reason they would apply some of the same logic to the cars break-in period.

If you new owners that are obviously ticked over these races in the Vipers favour - stop trying to grasp onto something - it won't turn into 'Supercar' after 500 miles.........geez. Yes break-in will add a few ponies but not alot like some of you think and it certainly won't fix heat soak either if that's what the car is seeing. Sometimes I wonder if some of you are bright enough to own this level of a car.

Seriously, I have to stop visiting this C7Z forum - I only do to read good things on this car but seems very little of it.......and little enough to change my future purchase plans.

People have asked for that ever since this forum came into existence, back in 1999.

GM does not want to go on public record about anything, so don't expect any replies from them, about anything.
