2013 - 2015 Audi RS5 Launch Control RPM Limit

[BuyTheWarranty]

Did some poking around and couldn't find anything on Audizine or similar forums. Does anyone know if there's a way to set the RPM range that the car launches at? I know with some tunes you can adjust it with the cruise control up/down dial but I don't think it works with a stock car.

When I first got the car, when I was playing around with it, it actually launched just under 8000RPM which ... was incredible ... but not something I'd like to do frequently (my car is stock). Each time after, it's been doing the standard 5500 RPM launch which is great! I found 2 videos on YouTube of the car doing a similar launch one of them here (I can't find the other one) but check it out 33 seconds in:



I know the car by default launches at 5500rpm but I was wondering if anyone had any experience with adjustments or the car launching at higher RPMS?

This guy has a launch at 8k rpm too, which is odd. I believe if you are launching at 8k and you feel pulling before releasing, you are in fact not using launch control as launch control adjusts the driveline too. Check with Vag-com users to see if it a field you can edit.

[JamesRS5]

That isn’t launch control, to engage launch control you would deselect stability, select S on the shifter, foot on the brake and then fully depress the throttle.

This guy as in you? Did it only happen once?

[altobeast]

No it was the video you posted. He didn't launch properly. meaning both your first time and his time on video, it wasn't a proper launch, either because you were only in sport ESC or because you had it in drive not sport transmission.

What do you mean by not a proper launch? It definitely launched, and all 4 wheels smoked for a good 20 feet :P

It's a good launch, but not under launch control. Launch control is set at an RPM point (5K) at this point which optimizes wheelspin and longevity. Launching at 8k is also launching, but not under launch control, you are just redlining then launching rather than having the computer limit RPM to 5000, which is the stall speed of the torque converter, I believe.

Thanks, though I have no issue launching the car. I’m just curious why it launched at 7800rpm sometimes.

[JamesRS5]

Your forum user name should become apparent if you keep launching at the rev limiter.

If you read the original post I said it happened once and I wasn’t sure why, this is why I was asking other members if they had any experience with this. I had also found videos of other folks launching it at higher rpms. Each time after it has launched at 5500rpm. Thanks for your “input” though...

[JamesRS5]

Hey don’t be so sensitive, I’ve already given “input” above where I said you aren’t launching it in launch mode or at least you haven’t entered launch mode correctly if the car is on the 8250rpm rev limiter instead of the launch control rev hold of 5000rpm.

[jpenneck]

I tried it yesterday in my car, three times in a row, and it always revved to 5,500. What procedure are you using ? This is what I did:

1. Put the car in Sport mode
2. Press the ESC button so it's in Sport mode, or ESC off. It doesn't matter which as far as I can tell.
3. Press the brake pedal hard, to the floor.
4. Press the throttle to the floor.
5. Revs quickly build and then hold at 5,500.
6. Release brake and keep the throttle to the floor.

WHOOSH!

Went to the track last night annnnd brutal!

Best time was 13.6 with no launch, just gunning it (and mid to low 14s trying to launch as it would bog down) as the car wouldn’t go into launch control mode. I’ve done it before with no problems, it’s almost as if the ECU wouldn’t allow it, as I was creeping up to the lights, it was super frustrating. I did about 6 runs and it wouldn’t launch, not even once.

When driving back to reset for the 1/4 I was able to get it into launch mode once just sitting still. My friend who’s a member here had his RS5 out, and tried in my car as well and it wasn’t happening. When I left the track I was able to do it coming home just sitting at a light which leads me to believe it was almost resetting something as I was approaching the track lights and creeping forward on the brakes.

Anyone have any thoughts?

I'm guessing that if you set launch, and then creep forward, releasing some pressure from the brakes, that you've just disengaged launch control. When you crept forward, and assuming you're pressing on the accelerator, was the RPM sitting at the LC-specifified point or was it at redline?

Heya! No, I kept creeping forward to engage both sets of lights for the track set: Once both lights were set, I depress the brake all the way down when stationary, and floored the gas. RPMs went to only 2000, which meant launch wasn’t activating and when I let go of the brake it bogged down to like 500RPM for a terrible start.

I tried 6 times, even let my buddy let me get set first at the start and it wasnt happening. On the drive back to get in line, I tried another 3-5 times and it only engaged once. I tried a combination of drive modes, traction off, traction completely off, sport mode, drive mode, paddle mode etc

[JamesRS5]

It still sounds like you aren’t entering Launch Control Mode correctly, it’s a machine, a digital computer machine at that so you have to follow the procedure exactly or it won’t work.

Also note that if the transmission is hot, launch control mode won’t engage so repeated attempts to launch the car probably put you in that situation.

I’m fairly certain I was entering the mode correctly, however, the transmission being hot is likely the culprit! It was quite hot and the line to race was fairly long. What a frustrating night, I’m quite sure with a proper launch I would have done mid to high 12s. The RS5 without a launch isn’t very fun :p

[digitalchris]

To be sure you're using Launch Control, you can hook up a Carista (or other ODB, I have Carista though)-- the car tracks how many launches it's done in its lifetime. Check it before and after you "launch" and verify that the number has gone up.

Now that I think about it, I believe there is a hard limit for the lifetime of the car (WTF right?)....

Well then I hope you bough the warranty. And either way the RS5 isn't a fast straight line car, idk why people buy it thinking it'll blow the doors off everyone on the street (which it won't) but rather the 5 comes alive throwing it around in the twisties. To hell with the launch mode I say

[JamesRS5]

I can honestly say in 3 years of ownership my Launch Control count will be reading zero. The initial traction is great but it’s not a quick car, it is a great handling car though.

I seem to remember a number of 50 being the maximum launches on the counter, not sure how accurate my memory is though, a weekend in Amsterdam did some irreparable damage.

...lol... as it should.....!!!

..good that an opportunity was not missed...

But can be increased to near limitless via DSG Tune (APR).

That limiter has not been shown to be on the RS5, or at least I haven't seen any indication of it from posts I've seen. But yeah I've done it 2 times and that is enough, launching from a standstill is just as good as the car isn't a rocket, but it's quick and can still run stoplight to stoplight fairly well. Canyon carving though, not much can keep up .

[BuyTheWarranty]

Thought this was interesting now that we’ve seen JHM do a 0-60 in 3.7 seconds with their tune and launch control. Myself and other members are nowhere close, my best time is 4.2 seconds in LC in auto mode.

Apparently times can be improved by switching into manual mode after the launch. From Audi World:

A big tip to help. The RS5 has the same DSG as the S4 with the 3.0T. So they are prone to some of the same issues if you don't have a DSG tune.. To get a good time the S4 guys launch off LC and then quickly shift into manual mode. This stops the car from short shifting out of first gear. That's the magic formula. As the cars all sort shift out of first and it kills the 1/4 mile times and makes it not consistant. The better the run the more likely it will be to short shift.

Anyone tried launching in manual mode?

You can't actually 'launch' IN manual mode - you have to use the cpu launch control system to get the initial launch, then right before 1st gear ends, click the right paddle to manually upshift into 2nd. It's weird but I find the paddles are faster at shifting into the next gear vs using the gear control lever on the center console so I always use the paddles. This tip is interesting but getting the timing right to paddle-shift 1 into 2 will def require a lot of practice as it launches so hard using LC, it's truly a matter of split-second timing to get it right.

[BuyTheWarranty]

Interesting. I am actually able to “launch” at 5500 rpm in dynamic using paddles. I watched a few S4 DSG guys on YouTube and gave it a try.
