I believe that the purpose of my thread was how to get the best 0-60mph acceleration on L99
maybe we could get back on topic? |

The best acceleration for most guys is achieved by using D or M (Sport) letting the computer do the shifting. The majority of the fastest track times in this forum are by guys letting the computer do the shifting. I've always used D or M (Sport) at the track when drag racing. My times have also been near the top of the fast list (mod vs mod). Using the tap shifts can produce fast times, but it very hard to make the 1-2 shift correctly. Most guys will bounce off the rev limiter or shift too early. 1st gear on the L99 A6 is very aggressive (redlines by 37mph). It can be really hard to keep your eyes on the road while watching the tach to make a correct shift. The tap shifts also have a slight delay so you have to shift at a lower rpm that expected. So for most people, you'll run faster 0-60mph times and 1/4 mile times if you just use D or M (Sport) with the traction control off and let the computer do the shifting. If you want you can turn everything off (hold TC down for 7 seconds). But I've always just turned off the TC. Both modes will produce good times. Last edited by SGOS252382; 04-21-2010 at 05:52 AM. |

The above post is correct in that the 1ST-2ND shift is definately tough to get right although I do believe can produce the fastest times when you get it right. When you let the computer do the shifting you can excpect very consistent and strong 1/4 passes, great if you're a bracket racer.Remember though, if you do the same thing every time you will get the same results every time.

if your unsure when in S Mode if the car is in 1st or 2nd gear:
at a dead stop, put car from D to M. tap the downshift button on the steering wheel. while doing this watch your RPM guage for a bump in RPMs. put shifter back to D. put shifter back to M and you should be in 1st. but like explained above, if you were not using tapshift and in S Mode, then the car should already be in 1st.

Guys, it's really very simple. If you were starting off in second gear, not only would your times be significantly slower, but you would run out to 60mph without a gear change. Not really hard to figure out. Just watch the tacometer and speedometer. |

However, to get back to the straight topic, on a stock SS A6, my best run was in 'D' and nothing turned off. I just floored it timing my left foot with my right. My left foot holding the brake and my right foot going down HARD on the accelerator to the floor. I've tried to 'Guide' the torque with the throttle but it is what it is. Conditions may be why this was the best way. It was a newly paved road and my car hooked up really good.

He was timing it.... I think he's talking about his foot timing from brake to gas.

You are adding to the confusion. How can you own an L99 and be so wrong?? Go out an try it sometime.

It appears everyone here is now in violent agreement:
Bottom line: Normally, you'll get better times in D or M. Once in awhile, when you get lucky (or if you practice in tap-shift mode enough), you'll get a faster time than you could have gotten in D or M mode. Seems to me it would be fun to try all three options, many many times, and keep a log of the results. Would be interesting to see the results of, say 100 runs in each mode to compare the results.

I always run my car using D (just plain old regular D with TC off) and my 60' times are in the 1.9x range (stock tires). My biggest issue is wheel spin/hop if I try to launch too aggressively. My best 60' times are when I make a smooth gentle launch (TC off). Last edited by SGOS252382; 07-02-2010 at 06:08 PM. |
