RS3 Launch tips

[Burningcoals]

I am new to RS3. I watched a video and it said put it in park, hold traction off, then brake and gas... Something like that. Might be wrong on order.

Anyway, It appears you can do launch control multiple ways?

Someone said just hold traction control and mash break and then gas, but I think I had to put it into neutral then back to sport to get the tranny to release?

Would love to shed the light on the most fast and quickest way to launch the car, like you pull up to a light and your ready to go.

Also for technique, do you hold it and try and get boost to build more? Will it even build more?

Do you let off the break immediately, like just dump it? Or do you let it off naturally, with probably a more gradual break release?

1. Gearbox in "S" or "manual"
2. ESP Sport or OFF
3. When in "S" or "M1" press the brake pedal and floor the gas pedal. Release the brake pedal quite fast after aprox 2 Seconds :)

Simple as that

Off topic, it's really funny how many people that used to have big turbo B5 S4 builds moved to the RS3.

Closest car in size and power to the B5, I know thats why I ordered the car. The A4/S4 is just to big now..

Seems to be the easiest way to do it.

Fyi it will build boost if held but I havent found the couple lbs of boost to be beneficial

Almost every time I launch the car it bogs down a little and then goes

I'd say the car can benefit from a higher rpm for launch control

Stock?
Tuned i get no bogging and a lot of wheelspin..

Mine never bogs, just pulling like a beast :)

I try to catch it as it hits 3500 that way I don’t blow the tires off (Stage 1). Very close to finding the sweet spot. Anything longer than a second is too much.

what tune do you have and what tires

fyi im unitronic 1+ with 255 30 19 ps4s and have no problems with traction, if anything i have too much

Your car probably still drags the rear brakes on launch to tame the beast I’m going untamed. Lol

care to explain?

[Rocketsauce16]

I can’t remember the exact coding but it was under Haldex and ABS where we changed the settings to have less interference from the systems. I just know it matches it with the ttrs.

Same but with Custom Code, Pilot 4S’s 255/35/19 on 19” R8 wheels.

have you done any logging or are able to see how much boost is being made with launch control?

[saxon]

here is a video of my car on the street with factory tcu/launch control and Unitronic 1+ ecu tune

Is it me or is it bogging off the line?

This thread turned a little odd. With 2 people saying they light the tires up on launch? I have never seen a RS3 do that, not even on a 9 sec pass, or any videos online. If anything almost all videos show tranny slip of some form, especially on the big turbo builds. However, I guess if you are on a random road in mexico that doesn't have a track surface you could get spin, but the launch control is pretty good about gradually getting into the power, probably easy on the drivetrain.

Any of you with tire spin issues care to get a video? Or how about post up your times?

Also, do any of you use manual vs sport? Are you able to eek out better times with manual? I seem to get better times in sport. Stock I am only getting 1.0g lateral acceleration.

[BaltimoreCaesar]

I've had tires spin a bit last fall when I had traction completely turned off on my bone stock rs3

[Potatohead_RS3]

Yeah with cold tires on the street mine will spin for a tiny bit too. On a prepped track a stock car won’t spin.

[Burningcoals]

How is your shifting on launch? I was under the impression that DSG would be a bit smoother, but on my car you can really feel the shifts on launching, it aggressively shifts to the next gear and you feel a yank when it happens. Its a smooth yank, not totally abrupt.

Anyone else experience the same thing?

Wait until you track, running flat out in Dynamic with the TC off. The drive home is always fun, the dsg doesn't know what to do for the first few miles

[0000 RS5]

I’ve noticed when cold it is much less smooth.

Don't mean to necro this thread, but didn't want to start another one. Just got a Dragy and played around with it on my bone stock RS3 with the P0 tires. I've only launched it a handful of times. My first try on Dragy got me a 3.84s 0-60, in just S with pretty cool tires (first run). I didn't have enough space to do a full quarter mile.

When is the optimal time to let go of the brake? Is it when the RPM hits 3000-3500 (which seems relatively quickly after releasing the brake) or when the boost rises (which seems to take a bit longer)?

It's my understanding with launch control, you hold the brake down, mash the throttle, and right when rpm hits about 3-3.5k you let off break. You don't want it sitting at 3-3.5k too long at all. Haven't heard of people looking at the boost guage when launching, but I'm no expert.

Completely agree with launching ASAP. I have multiple draggy run testing what's fastest and, with summer wheel and good traction, TC off and launching as soon as you hit the LC limiter 3-3.5k RPM is when you should launch. With my winter wheels with a bit shittier traction, launching with TC sport mode and as soon as you hit the limiter is the way to go. On stage 1 (93 octane) + I get 3.3x if I Launch asap or 3.4x is I stay on the LC limiter a bit too long. All of this with the stock pzero tires.

Stock I found that I got the best times when launching when the boost gauge got right to the B in Boost. 3.7x stock on a pretty terrible road.

[PowerStroke]

Interesting, thanks. Looking forward to doing a few more runs stock, then throwing on PS4s with the Uni 1+ tune for comparison in a few weeks.

[whitewaterguy87]

I am looking forward to getting the stock Summer tires back on and seeing how well it improves over my winter set up! I don't like the silver rim but I know the car has a much better 0-60 with traction! I just don't launch the car very much with not have a DSG Catch Can yet. I have been told that rapping a rag around it for testing will not hurt it?

[keninblaine]

Does it make any difference, or matter, whether TC is in Sport or Off? And how important is a DSG Catch Can for someone that seldom does launches? I have a Unitronic Stage 1 ECU and TCU flash.

[TwistRate]

The tuner should be able to produce a LC sequence that continues to build boost while at the line and doesn't suffocate itself if left bouncing off the stationary rpm limiter. Any tuner that tells you the best time to launch is exactly at 3500rpm doesn't understand the 95% of us are running from an arm drop or pro tree. We don't have the luxury of releasing the brake when your tune permits.

Find a tuner that can reproduce your short time back to back whether you hold it for 1 second or 3 seconds.
