L99 launch, no one using comp mode?

[acatlover13]

It depends on what competition you are competing in. My understanding is that competitive mode is T/C on and stabilitrak off. At the drag strip, this will yield significantly slower times. I have no personal experience with a road course, but I'm assuming that is what it was meant for.

I have done it both ways and have not seen a difference at the track how ever on the street, competitive mode works great as it gives you just enough traction so that you don't roast your tires even though you have traction control off. I also found that I can reduce my ET by shifting myself with the paddle shift, just make sure you shift before the limiter hits. With practice you will know exactly when to hit the buttons for eack shift and as I said, I reduced my time by 1 tenth and picked up almost 1 mile per hour in the quarter mile.

With the A6, when you come to a stop in Sport mode, and click into competitive mode, will the trans hold the car at a specific rpm if you hold the brake and floor the gas, or will the car try to take off like normally when you give it gas? Ive read that it will hold the rpms for you until you release the brake similar to launch control on the manual transmissions.

to take off properly with an L99:

- come to a complete stop.
- shift into "M".
- turn off Traction Control by tapping that button down by the gear shift, once.
- tap the left paddle to drop it into 1st gear.
- let off the brake and punch it.
- shift at the desired RPM.

When in D or M youtake off in 1st gear, guaranteed. Only when using the paddles and letting the transmission downshift to a stop, will you be in 2nd gear.

You will hit the rpm limiter if you wait too long. I've done it a few times. REALLY makes you look bad.

No. It won't.

BTW... are you coming to the event in my Sig... time to give that car of yours a run...

When I'm in "M" and in Competition Mode (which is all the time) my L99 always starts off in 1st gear!

Trust me. I've been racing my L99 A6 for 15 months and I've always used D.

For anyone that doesn't believe me please just do this in your car.

Drive around with the car in D (Drive). Then come to a complete stop. Then mash the gas to the floor like you're racing. Your car will shift from 1st to 2nd gear at 37 mph. Why? Because that's the shift point (5700 rpms) for 1st gear (NOT 2nd gear).

If your car was in 2nd gear, it wouldn't shift until 64 mph (that's the 2nd to 3rd gear shift point).

When drag racing from a dead stop, how could your car shift at 5800 rpms at 37 mph if it wasn't in 1st gear? 5800 rpms doesn't come until 64 mph in 2nd gear.

Its common sense.

Looking at the programming for the camaro's computer through hptuners on my pc. If your car shifts around 30mph at full throttle, you are doing a 1-2 shift. If it's shifting around 55mph at full throttle, it is a 2-3 shift. Just try it out... There will be a little lag, so it might be 35mph and 60mph, but it will be obvious enough.

It is obvious, but some guys just don't get it.

For some reason, they don't understand. If their car is shifting at 35 mph (5700 rpms) or so at full throttle, it has to be in
1st gear. It CAN NOT be in 2nd gear.

Dude... I completely agree... maybe I shouldn't have posted... was thinking about a normal street driving take off, not racing... I stand corrected and I do get it, just didn't want to take the time to explain..

Thanks for clarifying.. I def don't want to get this one started again...

Sorry but I have to strongly disagree with this statement. Having tried it myself my car always runs faster with both the t/c and the stabiltrak off.

I've been saying that for a year. It's obvious to me as well.

I even started really slow and tried to go faster at a slow enough of a pace as to not let it shift again, and see when it shifts. Even taking off like a grandma, it seems to still be in first gear.

He may have been saying that if you couldn't hook up. And you spin the tires too much.

Though I agree with you, I will say this: My fastest time run yet was in drive with everything ON and in 'D'

But my average times are about .05 faster with it all off and in 'M'

Go figure.

But what if u pull it into m and leave from a dead stop under full throttle?
R u saying your in 2nd gear?

how do you explain the difference in take-off torque?

yeah, if you mash the accelerator - it will. but while driving "normally", you either take off in 2nd gear, or, the shift is so soon that i've never noticed.

my car must be silly, because 1st gear gets me off the starting line real quick, but i'm nowhere near 37mph when i start red-lining in 1st.

full throttle, "M", i'm sure it'll drop it into 1st pretty quickly... you may even feel it shift from 2nd to 1st when you're taking off.
