What I mean is you can't seem to stall it up like your standard auto where you can brake stall till certain rpm and launch.
It will let you brake boost till 2000 rpm but when you launch it seems to fall on its face and then move out.
Does this have anything to do with a torque converter ?
Thanks in advance.

Will try this and get back to you....

Why would you do this ? would this not be bad for the tranny ?

The E550 does not launch like that. It was not designed to. Maybe you should have gotten a sports car?

^ or the E63 AMG series.. which has the race start option.

I already have a 2008 Z06. If I could afford a E63 I would have gotten one But I do appreciate the advice from the 350 guys. . I also don't think a car doesn't have to be a sports car to be able to launch. Iam not talking about a dct gtr type of launch either, something more realistic.
If one has educated answer I would like to know. nothing personal either but besides it doesn't do it , there has got to be a more clear answer why. Iam thinking either computer might be doing something.

^^ We have something in common, I use to have a 08 Z06 new(back then) and I am about to order a 14 E550 4 matic (had a C63 AMG ater the Z06). In response to your question, I was talking to my sales person and you can disable traction control thus you can lunch nuts however I heard that most tuners limit the torque on first gear to prevent damage.

I have driven a 14 sedan(4 matic) and the E550 coupe and they both pull out of the whole like crazy, even the Coupe with the 255s in the back pulls like crazy from a dead stop, this has to do with the full torque at like 1600 or 1800 rpm which is basically as soon as the car starts revin.

Never thought of that I guess. I'll have to try
The coupes are like 3700lbs. so Iam sure they move out pretty well.
Good luck on your find brother.

Unfortunately most of the W212 buyers bought a Luxury car and not a sports car when they were shopping. So "launching" their E550 was and probably still is the last thing on their minds.
I just floor it, I have never tried a "launch" or have ever thought about it.

If you want a better answer I would suggest head over to the E coupe section or CLS. They both have the same engine and transmission as the E550 W212 but those buyers are more likely to be thinking about launching than the guys here.
Good luck

Either car (coupe of sedan) gets out of the whole impressively quick. The huge torque at 1800rpm just gets you off the line

Directions

1. Disable all nanny systems via steering wheel menus
2. Put car in sport mode
3. Paddle shift select 1
4. Hold brake and give gas to hold revs at 2500 rpm
5. Get off brake and put gas on the floor after about a second to (reduce wheel spin).

I will have to try and report back. thanks

No they don't, what you are thinking of is a High Stall Torque Converter. Our cars lock up around 2,200RPM to be as smooth and as torquey as possible.

If you did that in a non-4 Matic E550 you would start burning up the rear tires lol.

With 4 Matic the revs won't climb because, well, it's 4 wheel drive and the engine can't burn up all four tires, too much grip.

The only way to get the launch you seek is to upgrade the Torque Converter to something of a higher stall, so like 3,500 RPM and you can launch all the time. However, you have two issues with that. One, good luck finding someone to make one for you. Two, your smooth driveability will go out the window.

Hope this helps clear things up.

I have only done it once or twice. It feels weird to be on the brake and gas at the same time.

pdjv

This is more likely controlled by the ECM or the TCM. You can rev it a bit (1500 rpm or so) but that's about it - get a little too high, and the controllers step in and cut power. If you're looking for fast starts, leave it in Sport mode and keep the revs in the 1000-1500 rpm range.

usamuscle

Thanks guys, some good info here. Somewhat expected I guess . =)

Im guessing you have the biturbo, if so i have this problem as well. It seems as if the computer is opening the waste gates on the turbos when you do so. I have looked into adding a switch between the power wire on the vacuum controller under the hood but im just skurred to do so. Im currently clocking a best of 12:20 et and average mph of 117.49 with crappy 60' times of 2.0+++. That mph im trapping should put me mid 11's with a good 60'

Are you running a tune or are you running bone stock? That is impressive if you are 100% stock.

My "launch" is just pressing the brake to the floor so it is "holding" and then I put it in first gear with the paddles and basically stomp the gas to the floor when I wanna go.

I'm very familiar with an "official launch mode" like on the 911 Turbo etc but for me this works well enough...

badbenzz

With my sprint booster and tune my E550 digs out of the hole quite quick in fact surprisingly quick. Brake hold, stomp the gas, the backend drops and the front lifts off weeeeee

I played with launching using Torque after a mild OE tune. Not much difference, but that's why I have a Corvette. Pretty sure the 550 would take my C5 (roughly 385 HP @ the crank) in the 1/4 despite the extra poundage.

Don't think our 550's were made to play at the track; they are meant to go 155 for hours on end on the Autobahn. Not to say I did not try a few laps with the car lowered. I'll stick with the C5.

There are so many 350's where I live that people stop and comment when they realize it's a 550. Our cars really are the Hulk in a tuxedo. Added bonus is it's easier than expected to wrench on. Brakes especially are a breeze.

J.M.G.

Torque braking my 2012 E550 4matic does not work. If I play with the throttle while waiting at the line kicks in torque management. The, my M278 does not deliver full power in first gear. At least my 1/4 mile times are worse compared to launch without any throttle before brake release.

BlownS4

So what has produced a better launch for you?

J.M.G.

For 4matic E550s?

1. ESP off
2. Transmission in "S"
3. Suspension in "sport" (AIRMATIC only) for less drag
4. Left foot on the brake
5. Releasing brakes at the same moment when going WOT.

With my former M273 car, setting Transmission to "M" was a big advantage due to quicker shifts. However, in my M278 there is no difference between "S" and "M" regarding shift times.

My M278 (stock) does really fly!
