You are correct, my old friend; driver error could well be the most likely reason. When I punch the throttle from a stop it's a pretty violent take-off in the GT R.
Bish fully agreed !!:y |

I recall the sales guy saying that the car starts out in 2nd using C mode. Doesn't mean that it sits in 2nd at idle though.

Didn't drive my GTR today to check. Rather I drove my C63 S, and indeed this car starts in second. My thinking on why first in some/all of the GT cars is because of the tall first gear. Just a guess.

Interesting, and something I need to experiment with when the Polar Vortex has buggered off! lol |

Then you need to get your car checked; there is absolutely no way that I experience a two second lag from a stand still.
If you are doing this; mashing the pedal when stopped, make sure you're not in 'C' mode since the car has 2nd gear engaged when stopped in that mode, and if you go and 'mash the pedal', the DCT 'might' be taking a second to engage first before taking off. That 'could' be a source of the lag of which you speak. Bish I think this can be seen in videos on Youtube, where the GTR is always seams to leave the line late, by late I mean the smallest of a fraction. Am I splitting hairs, yes definitely. Given that the delay between amber lights is 0.500 seconds the car is reacting to my input about 1 to 1.5 seconds later. It is not a big deal, I know now to compensate for it and I am mostly just racing the clock but in big HP grudge matches it will become an issue if the other driver can cut a good light. The car does dig relatively hard, the best I could do was a 2.0 sixty foot on stock tires which is not bad I have just become a bit desensitized from years of drag racing. . |

So at a Stop/Idling the clutches in the DCT are not engaged, hence I'm not at all sure why the car would be in 1st gear when idling, only to change to 2nd when your foot comes off the brake.

I attended the event and here are my comments:
-AMG was well represented and all of the GTs were tuned. the highest mph was the GTR in this video at 156 and we were all in the low 15X. -The setup was from a dig and not from a roll which explains the lower trap speed that some of you are mentioning. -Traction was an issue all day and it got hot pretty quickly (80s by noon). -Since there were a GT, GTS and GTR, the tuning showed that all models basically achieved the same trap speed. The force was a bit stronger with this GTR in the video ;) but the claim of 700hp for tune only does not seem reasonable IMHO. -My worse time was 151 and my best was 153. Car was very consistent. The hp claim of 650 on the wannagofast website is incorrect as I am only tuned and will ask them to change it to 600. -A fully built Stage 3 (upgraded turbo) Weistec C63S ran a best of 169 (dyno of high 700) and put a beating on a Stage 3 (upgraded Turbo) 2018 M3 who ran a best of 161. 33 pounds of boost on the C63 is not for the faint of heart lol. Not sure why the C63 time is not on the website. -One of my race was with a TT huracan and it was eye opening and a blast to witness what 1,300hp does to a car with less than half that horsepower. Felt like I was standing still when he passed me at the 1/8 marker lmfao. He clocked in 190+. He got outdone later by another Huracan who did the same thing to him and clocked 218mph (winner of the day). -If you have never done of those events, I highly recommend it to anyone. It's a blast. |

Yeah. I tried it in all modes when I took the car to the track. It did the same thing each time.

I'd say the BMW driver used it's launch control feature and the Mercedes driver didn't, it makes a huge difference
|
Why the hell do you guys give a damn about who is faster in a straight line, a Sports Car is meant to corner not go straight.
Seriously you call yourselves drivers ? |

LC on these is a PITA to setup at the line. |

i thought M6 was AWD and it launched like one off that line, so yeah that’s probably what happened. That and slow jump on GTR. I noticed when running these that you can get on the gas a touch early. It’s not lag, just a very slight hesitation. LC on these is a PITA to setup at the line. It is enough to get drug off the line if you don't compensate for it. Agree, LC is useless, not enough time to set it up once staged and the result is just a bunch of wheel hop and spinning. Need drag radials to take full advantage of LC but then if you are running drags you don't need LC. |
Maybe sprint booster would help off line. Throttle response in all other gears is ridiculously great. |

Yeah it stays in first until shifting into second in the normal manner. It both idles and starts out in first. Wouldn't it be weird if it idled in first and as soon as you took your foot off the brake it shifted into second! |
Best way to launch with me was to completely take off ESC (press and hold for 2-3 ) and feather throttle 1/3 and then 2/3 a second or so later. Also, mich P4S 305s are way better than SS’s. |

Be in Sport/Sport+/Race modes; come to a complete stop; push down on the brake pedal hard, and then floor the throttle. Revs rise to a pre-set and when you’re ready to go just rapidly release the brake. Am I wrong? Granted I don’t do 1/4-1/2 mile runs as I run on road courses, so I’ve rarely used LC. Bish |
