06-V ONLY I have no idea how many of you V owners have found out about this, but the word "performance" is not used in connection with the staabilitrak or Traction Control in the owners manual.

What I found out, just by accident.
Tap the TC button on the console. For each time you tap it you will get the following, not necessarily in this order. This doesn't work on the 04. You guys with the 05's and 06's will have to try the tap method on your own and report.

Performance mode (with this setting, move the shifter to the left into the gate, but do not use the + and -. You have one hot Tamale in this setting.)
This is how I have been driving my V and this is why I really think this car is hotter than most company's that have had it on a track. Check it out and let me know.
Stabilitrak off
Stabilitrak ON
TC Off
TC ON
As most of you already know, you can still hold the button down for 5 seconds and TC/Stabilitrak is off, but this performance mode is a lot better.

In the Corvette it appears in the DIC as "Competitive Driving Mode". It's much safer than shutting off both stabilitrak and traction control since it allows the car to maintain a bit of it's "yaw control" just in case you over-drive a corner or over-steer the car into a spin.

I'm just trying to share what I find out on my own in hopes someone hasn't found these things before.

Hans,
Maybe I'll fix it to say under 4 after I get that damn air intake. Just dreaming in my Dream Machine.

Yea I guess it is, but I didn't read the post about hitting the button twice. I did find something else out over the weekend. I used the plus and minus instead of leaving the shifter in one spot and it's a lot faster. I also found out that if you don't shift out of 1st at 5000 rpms it Will starve for gas before it shifts into 2nd. I found that once the front of the car comes up, I can keep it up by shifting at that RPM. Sorry about the double information. Let's see where did I put my glasses.

I believe thats the rev-limiter... so you don't mess up the engine... :)

careful though....that's how I blew out my shift selector switch:mad
I intended to shift, but didn't click it up far enough, in a flash the RPMs were off the chart! It does save the motor though.

I'm not sure if the V has a spark or fuel-based rev limiter, however based on Bob's post it sounds like it pulls fuel. When that happens, there is a short period of time where your motor is running dangerously lean, since it's still trying to "fire" a progressively dwindling air/fuel mixture. Lean conditions in a S/C'ed motor are much more dangerous that in normally aspirated motors, so be careful not to hit that limiter any more than you have to.

Of course, the opposite is just as explosive since spark-based limiters pull spark with fuel continuing to flow. Once it fires again the you end up with a flaming tail pipe!

Heck, at night that might look good, these guys seem to like the effect!

After hearing about the conditions that could take place by the rev-limiter, I'm more convinced that we must shift in that first gear between 5,000 & 5,200 RP M's. I'm for 5,000 myself and I have notice that when the front end lifts in 1st gear and I shift at 5,000, it shifts so fast that the front doesn't start down, it just stays up and starts coming down slowly in the next few gears. We must keep an eye on the tach. It's also very embarrassing when it gurgles and the car your racing creeps by you until you can get a handle on the next gear...............I'm to old for this stuff, but I go home with a smile on my face. I'm still looking for that SL600 in my town that blew the doors off my 04 last year.

I wish I didn't have to answer that, because it makes me sound like I don't care about gas mileage and I do. Simply put, I haven't a clue, but I do use 87 for three fillups and then one 93 to clean it up. I see no difference in either octanes.
I know you mention the 2 black V's at your delaler quite often, but less face it, it's not a roadster color. I thinkk it looks bland. My Platinum is nice but I will say I think the infra red is the hot color, but will draw more tickets.

It's ALMOST irrevelent BUT what gas mileage are you getting now??

What Octane do you use?? 93 or 87??


FWIW: THERE ARE STILL 2 BLACK XLR-V'S HERE IN JAX WITH NOBODY'S NAME ON THEM. One was supposed to be mine if they could get me out of my Xenon Blue 04 LOTS OF LUCK ON THAT!!!
