Launch control for rs5

[tbone323]

Does the RS5 have a launch control mode? The manual mentions one but it’s shared with the S and A models. Also when I tried it today the RPMs were low (around 3k) versus the 5k or so I had expected based on previous threads I read in the past. When I tried it, the car took off but not sure it was ever in a different mode, sort
Of just felt like a good ole fashion brake stand...ha!

With my B9 S4 it was... ECS off, trans in S mode, engine at operating temp and steering wheel straight. Here is what that looked like..

Yes it does! If you press the ECS button once it goes into sport mode. You need to turn it completely off. To start, start out with the car already warmed up a bit or you can’t do it. Then, at a dead HOLD the ECS button down until you see in the screen between your gauges that the ECS has been completely turned off. If you don’t hold it down, it won’t turn off. It will turn to ECS sport first, but don’t let off the button. Keep holding until you see it says ECS off.

Next, push the brake, mat the gas until it revs to about 5k rpms ish, dump the brake, and keep your foot fully floored.

Good luck and enjoy!

Oh also- the car needs to be in dynamic mode or none of that works!

I also works with the ESC in sport mode. I’ve done it a few times without turning ESC completely off. Now, I haven’t paid super close attention to the RPMs, but I thought it was higher than 3k. Will have to check this out tomorrow.

You can call it for " launch control "but it's actually far from it. B9 RS5 has ZF box with torque converter so you just preloading torque converter.It has nothing to do with launch control in for example dual-clutch transmission where it works like real launch control.
Actually you can launch RS5 in the comfort mode as well in the same way.

[sepangrs5]

Just realized you had a B9! Didn’t know that. The way I described was with the B8. Might be the same, might not be. Is the B9 broken in yet? Maybe you can’t launch it under a certain amount of miles? Just a thought

The gear changes are also altered. You can see/hear that in my video at the 1/2 shift. It's quite the jolt.

For those that don't know, AMAX (acceleration max) is the 'launch program' you can engage when at operating temps, at a complete stop with the wheel straight, in sport mode with traction control off, and by pressing the brake and gas at the same time. Under normal shifts, the engine is de-rated (drops ignition out) and that's also what produces the classic exhaust 'fart'. With AMAX engaged, it 'keeps the beans on', and the car has a noticeable lurch forward when it shifts. This is worth at least 0.3-0.4 sec in the 0-60 time and is essential for good 1/4 mile results.

Ya sorry, should have clarified B9. As for mileage, ya I took delivery a few weeks back and am 1100

[sepangrs5]

Congrats on the new car! I know someone who was putting ABT tune on an RS5 B9 and couldn’t because it didn’t have 2000 yet. But that could just be because of the tune.

Mops, any thoughts here? Any issues launching yours / how many miles are on yours?

Played with it again today but didn’t execute the launch. Thought I’d share this video with what the car is doing...

Not launch control in the traditional sense as alluded above. A traditional launch control requires a transmission with a clutch so it can fully decouple from the engine in order for the engine to rev independently and then drop the clutch. The B9 RS5 has a torque converter, so the transmission is never decoupled from the engine. The "launch control" in the RS5 is a brake torque launch. It can only rev the engine to the torque converters stall speed which is around 3000 rpm and then basically take off w/o delay and the engine making boost already. The main purpose of the brake torque launch is mainly to build boost before you take off. Based on your video it looks like some parameter isn't met. I don't know for sure with the RS5, but many perf cars don't allow launch control until a certain mileage to make sure engine and transmission are properly broken in. The procedure for launch control is the same as with all other Audis. On second glance from what I can tell from your video, your ESP is on. It needs to be in Sport mode or Off.

I know the problem and it's a simple fix. When applying the brake, you have to apply very firm pressure -- almost as if you try to drive the brake pedal thru the floor. Everything else looks to be correct.

I’ll give that a shot. I thought I was pressing pretty hard but can’t hurt to try again! Thanks.

I believe everyone saying to turn traction control completely off is INCORRECT. In the RS5, the transmission needs to be in sport mode, traction control is just pressing the button to put it into sport mode, not holding it down to turn it completely off. In an Audi with a true dual clutch transmission you do need to turn off traction control completely, but in the ZF it needs to be in sport mode. Then its the normal procedure from there.

First part is mostly correct. For launch control you only need to press the ESP button once, which puts it in ESP Sport. That not only turns off traction control, but also relaxes ESP as a whole. In older cars prior to MY13, a single press of the ESP button only turned off traction control (ASR). The type of transmission doesn't matter. It's the same if the car has a dual clutch. Only needs to be in ESP Sport. The second part is correct. The transmission needs to be in S. The Drive Select mode doesn't matter. You can launch in Comfort mode, as long as the transmission is in S, or M as long as it was in S before going to M. The other things that have to be met is the front wheels need to point straight forward. Launch control won't activate if the wheels are pointing left or right and lastly, the transmission has to be at operating temperature. Not too cold and not too hot. Launch control won't engage if the transmission hasn't reached operating temperature yet, or if it's getting too hot. Problem with the latter is that as opposed to some other performance cars, there is no readout for the transmission temperature, so you don't know if it's too cold or too hot if it refuses to engage.

My prior B8.5 S4 with dual clutch did not need to have ESC completely off, just sport mode.

Sequence was: Dynamic Drive Select. ESC in sport mode. Transmission in Sport. Brake pedal to the floor. Gas to the floor. Wait until RPMs settle. Release brake. Hold on.

I have not done a launch with by B9 RS5 as I only have 350 miles on it. I would assume the sequence was similar/identical.

[DFWRS5]

I have not tried launch control yet either as I only have about 500 break-in miles. If you are on a drag strip does the car perform better by letting the transmission shift for itself or is it better to put it into manual mode?

[KUbeastmode]

Using launch control properly doesn't have the car in M mode. Keeping it in S is faster IMO

What is "real launch control"? Launch control is not about dumping a clutch, whether that be on a manual or DSG transmission. It's simply a way to get the engine speed into its torque range before leaving, and managing traction thereafter to minimize wheel spin and maximize acceleration. Brake torquing on the B9 RS5 takes the engine to about 2000 rpm (beginning of torque curve) whereas Launch Control goes to about 3000. That said, brake torquing does provide a hard launch. Perhaps launch control does other things though, such as provide some safety features, but that is just conjecture on my part. I rarely use either approach, but both work and they are different.

Regarding the B9 RS5, you need to be in Dynamic, Sport and ESC Sport for Launch Control to work.
