Launch Control

[MichiganRS3]

Is it disabled until the car (coolant / oil) is at a certain temp?

Tried to use it today, car had only been driven for about 2 miles, it was 45 outside, and when I went to use it, the back end just squatted down.

I think it was the APR tune letting me left foot brake, but was definitely not launch control.

Did you have it in “Sport” mode and the traction control off?

Yes.

I did it again once the oil temp was around 189, worked fine. Must be some kind of protection system.

Does a light come on letting you know it's active; my last BMW had that, but I've only tried launching the RS3 once, it revved to about 2,500 or 3k don't recall and then I went, but hard to know if that was it?

I would guess an intervention occurs when not full temp is not reached.
Shoot, the max rpm comes on rarely, during cold starts, saying I can't pass 5500rpm, for about a minute or less.

[Venumous]

Seems highly Ill advised to not let the car warm up significantly longer before beating on it.

If the brake pedal is not properly pressed hard you wouldn't get the launch control.

[bpollock]

Why would you try to launch when the cars not warmed up? When I first start the car when it’s cold I get a warning and a dash light that says not to exceed 5500 rpm

[dnchattan]

Yeah, the car disables launch control until it is up to temp. Similarly, it will do so if the transmission temps are too high. It’s all to protect the engine and transmission. I wouldn’t try launching until the car is fully up to operating temp regardless of protections though.

I don’t move the car till the warmup procedure is complete (rpms drop to normal). I don’t go full throttle till after the system has determined the car can do so (redline moves from 5500-7k).

This was after about 2 miles of driving.

I have pulled a 3.17 0-60, so I’m well aware of how to use launch control, which is how I knew as soon as it happened that LC was not active. I think oil temp between 170/180 is where it allows LC to activate.

[dnchattan]

That sounds about right for when LC activates.

While the car seems to indicate it’s “safe” to go full throttle by removing the redline restriction, generally I wait until at least 160 for any full throttle pulls. Especially in cold weather I use this as a rough approximation when the transmission is warmed up too (since I don’t have a gauge for tranny temp). The DSG does *not* like being used hard before it is warmed up (esp when using manual shifting). I’ve tried launching in previous DSG cars while it was too cold and the shifts felt like something was breaking.

That’s all I’ll add here in case it is useful to you or anyone else- but in the end it’s your car - drive it however it makes you happy

Oil temp needs to be above 70c (160f) for launch control to be enabled. Oil temp can take upto 5 miles to get to that temp from cold dependent on outside temps and driving conditions. Fortunately for the stupid that live amongst us, Audi build in some protection measures. The first restriction is engine performance (rev restriction), this is then followed by Launch restriction until warm.

I'm the same, won't bother with 4000rpm + performance from cold until I see the oil at 70c (160f) - it's just common sense.

There's no teaching stupid.

My 2018 TTRS (bone stock) goes into LC mode at 3500RPM, anytime.

I once tried engaging LC as soon as I started the car in the parking lot (S mode/TC fully turned off). It worked!! I was very surprised. This was in the summer months but the car had been turned off and sitting in the parking lot for 4 hours. Haven't tried this in the winter and I don't think I will.

I did not launch it, obviously haha. However, my F80 M3 was real finicky with LC and EVERYTHING had to be justttttt right. Half the time it didn't work. I wanted to see if the TTRS was the same. My Launch Control works as soon as I start the car with zero driving.

Oh, one time I also launched it 6 times in a 30 minute window. I was racing my buddies tuned S3 in Mexico. He had a transmission/overheat error pop up. The TTRS was solid. I love this car because it can handle launches and abuse quite well. My buddies GTR starts throwing a fit after 2 launch control starts and the tranny starts to overheat.

[PowerStroke]

What kind of Gs are you guys pulling when using LC?

[OE2]

100% stock at the track

[MichiganRS3]

I’ve launched on a 4.1 0-60 and pulled 1g, and 3.17 0-60 and pulled 1g. My dash cam recorded 1.3 on the 3.17 launch.

Anyone ever see more than 1 on the dash?

[PowerStroke]

Interesting. I launched in yesterday and it was about 45F out, still on pirelli summers, entirely stock and hit 1g. also felt some wheel slip at the start. can't wait to try this in the spring with michelin pilot sports!

I own a RS3 2018 and i found a Oem winter kit that use to be on a Audi S4 2005 (B5).. i dont know if this would fit since the calipers and rotors are so big!! I wonder if anyone as ever tried before??Anybody can help me whit this please!! thanks

Not a chance those will fit

1.1G with Neuspeed 18's and BFG Rival S 1.5's otherwise stock. I'm sure the guys running sticky tires with mods are hitting higher.

[SlowSedans]

The indicator that LC is active is the g-meter. The perimeter of the circle is white normally, when you are stopped and it turns red that means it is active. It does have a temperature safety for both too cold and too hot.

[PowerStroke]

Now that it's getting colder -- any downside of doing launch control on winter tires? Is LC inherently worse for a high performance winter tire (i've got michelin PA4s) than for summer tires?

I don't want to wait 5 months until doing another launch, but i would if it's going to tear my tires to shreds!

I just got the same tires today and asked the same question.
I will still launch just not as much as with summer tires.
Now come on APR and launch the TCU tune so i can delete the launch counter!

Is there any harm revving the car without launch control getting activated when i mess up and forget to turn traction control off (banghead). Ive done this a couple times. The car definitely doesnt seem to like it and lurches a little then stops. Im guessing there is some safety feature built in to not “rev while in drive at a stop”

I also dont really see why launch control would be any different with winter tires.

I don't believe any tuner or at least off the shelf tuners like Unitronic and/or APR have not figured out how to delete the launch counter. At least they haven't shared it with the public..

I was under the impression that most/if not all tunes got rid of the limit (especially unitronic)

Yes.. With APR and Unitronic the launch limit is increased from 200 to something in the 1,000's (3,000 if I recall). What has not been figured out is how to delete the launch counter or reset it to zero..
