FWIW I find it easier to manage this when using the 'hold' brake feature.

I use this every time I have to stop even if it's just for a second. I find that a very light throttle application transitioning from 'hold' lets the clutch slip very quickly. It also speeds up the reaction time in traffic because your foot is on the gas already and doesn't have to move over from the brake pedal which helps to slow the 'lag time'.

I thought the issue was significantly improved after they reset my transmission after the new firmware was uploaded.

That said, its back to the old gas...........................................go. I am assuming its almost always specific to the MCT-7. Its a weird transmission. Other cars that go on depressing the pedal all seem to have standard torque converters.

My father-in-law has an SLS. No lag there at all, but its a DCT and N/A. I don't think the turbo lag has anything to do with it. A 5.5l v8 has enough power at 1 atmosphere to get up and go.

it does make perfect sense, wht it doesn't make any sense is inconsistency....by all means I am no expert to the subject, but you would think that there would be some consistency.

Its when you come to a fast stop like at a street corner and then try to pull out immediately. Its almost like the computer has to catch up

May it has nothing to do with the firmware but rather the tcu reset

Chocofishez

I know what you mean.

If you are driving quickly put it in sport mode. I find it clears up a lot of the low speed ecu / tcu issues. There is an awful lot of power in this car and even with AWD you can get into trouble if you are an idiot so the nanny net is too intrusive when you want to accelerate, brake and turn quickly.

For the situation you describe it also helps to be in M mode and downshift yourself into first before stopping to force the tranny down... Otherwise it's not totally sure if you are going to come to a full stop so delays first gear a little too long. Remember the car has an adaptive tranny so if you are in C and just sedately cruising around 95% of the time then ask it to be a full fledged AMG again it takes a second to snap it out of the style it has gotten used to. I am quick to turn the MCT dial a notch if I anticipate needing more performance or better yet use the AMG memory button because that's what I feel it's there for. The car has two personalities might as well experience all that you paid for.

we recently got the E63, and having recently been in the E55 that it replaced, one of my initial impressions of the 63 was that it didn't feel nearly as responsive and violent as the 55 did at low speeds. i initially only attributed it to it being turbocharged and AWD compared to supercharged and RWD, but the MCT thing makes sense. silly MCT, and your slippage... hell my 16 year old lexus feels much quicker off the line than the E63, use race start and that becomes a different story. speaking of which, does anyone else also feel that it isn't THAT impressive, at least compared to other launch control systems which are designed to keep the tires at just the limit of grip whereas this one still feels like it's holding back. how can a GT-R be just about a full second quicker to 60?

robl45

Because its a GT-R I'm surprised you have that impression of race start with the AWD. I tried it once about a month ago when I got my car and with the RWD it just spun the tires around.

Chocofishez

It took me a while to warm up to the car when I first got it for exactly the same reason you mentioned... It felt sluggish and less responsive at low speeds compared to the C63 I had just come out of. The transmission isn't perfect but once you figure out how to use it and the adaptive software starts to get it right with how you drive in each setting it starts to make sense.

And remember the E63 is a full size super sedan. What it gives up in low speed responsiveness it makes up for with a sublime ride, luxurious interior, all the whiz bang electronics, sound system etc. The 0-60 is a headline grabber and is a cool parlour trick to have in your back pocket but really isn't what this car is about at all.

Being a year and a half and 23k Kms into the car I am thrilled with it. It is the best do it all car at any price.

stroock6394

oh don't get me wrong, the race start is an awesome thing to use to freak people out. even with using it you just get the feeling that there's still quite a bit more grip to be utilized. i suppose by not being as violent as the gtrs launch control it'll increase longevity of certain parts, but i still think it should have like a f**k it, yolo mode where the clutch bangs in just enough to break a little bit of traction. 600 ft lbs from a 5.5 liter V8 and it doesn't even do the slightest hint of burnout.

don't let this mislead anyone, the E63 S is an AWESOME car, i don't know if there's anything else that offers this level of performance, practicality, usability, refinement, luxury, comfort, (efficiency?) and lack of ugliness for $100,000. don't forget that with only a few thousand $ more worth of tuning, the car can be as quick as a ferrari enzo, all for under $110,000

GTR's are getting to 60 in the low 2's now?

stroock6394

for AMG's sake i hope not


if anything the road was ever so slightly downhill in this vid. have you ever timed your E63 0-60? i know it's claimed 3.4-3.5 seconds, but i haven't seen one do that. even a 700 hp tuned E63 doesn't break 3.1-3.2 seconds using race start

ace10

When the E63S was launched, MB claimed a 3.2 second 0-60. They backed off that number a bit because it looked bad for the rest of the pricier product lineup. They now claim 3.4.

Everything I've ever seen or read shows actual test times of 3.2 to 3.4. Wagons contributing the slower times, for the most part.

As shown here:
http://www.0-60specs.com/mercedes-be...mg-0-60-times/

Same mags test the 2015 GTR at 2.9-3.0

The Nissan isn't a full second faster than the E6S.

stroock6394

i see the numbers, but i don't think anybody has produced a video of one doing it in that time. i have 2 launches on my channel, and they were 3.9 and 4.0 0-60. is brake torquing it quicker than using race start? please tell me i'm missing something, i'd love for the car to do a 3.5 0-60

AMS claims 2.85 seconds from 0 to 60 with the Alpha 7 package -- AMS tune, downpipes and exhaust.

ace10

At the AMGDA, I tried to brake torque an SLK55 on the autox course, and it bogged. The autox instructor told me that all of the AMG's respond poorly to that technique.

stroock6394

ok i tried to be as scientific as i could with this one... i downloaded the clip of the ams e63 speedometer, opened it with quicktime player and set the starting point at when the brake was released. in their video they just brake torque it and aren't even using race start by the way... the video was shot at 30 frames per second, and the speedometer hit 60 after 3 seconds plus 10 additional frames had passed. 10 frames at 30 frames per second is roughly a 1/3 of a second (10 divided by 30) so give or take a slight margin of error figure it took about 3.3-3.4 seconds. there's another video i've seen of an e63 s with the same modifications (from pp performance instead of ams) and using race start that did it in about 3.1 seconds. as much as i'd LOVE for the claims of ams to be true, the car in that video did not hit 60 in the 2's. still ran the 1/4 in 10.85 or something though

I came from an 06 E55+Sprintbooster. When I first got 2013 E63, it felt "marginally" sportier than my healthy E55. I was considering the Sprintbooster again, because of the throttle lag. I did get the OE Tune during year-end sale and all I can say is that (including the TCU reset) turned the 63 into the "next-gen" $100k BEAST that I expected. Throttle lag is not an issue and no longer considering sprintbooster. I do recommend(as did OE) driving the hell out of the car after TCU reset, during the first couple hundred miles.

Now if anyone could figure out an end-user way of doing the sneaky tcu-reset as the W211!

It's doing the same thing in my 2015 e63s. I dropped it off at the dealer and they said they can't find a problem.
It is not. Let me be clear here!! A turbo lag issue. It's an intermittent problem.

I can replicate it 85% of the time. By coming to a 98% stop and merging into traffic. The car bogs down for almost a full second. And even then it gradually eases into speed.
This is not just an inconvenience but a danger. I have almost been rear ended 3 times because of this.
And no it's not because I think I have a fast car and I can cut into a open spot.
The car comes almost to a complete stop and then starts to take off at like 10% of power. It's like its trying to take off from a standstill in 3 or 4th gear.
I am almost at the point where I don't feel safe with this car merging into 30mph traffic with my family in the car.
I am just not shure how I can data log this to prove it to Mercedes and the dealer.
I am going to hookup the my Mbstar unit and see if I can datalog TPS vs Speed vs what gear I am in.

Couldn't help but smile for this one

I think probably mb put this lag in intentionally because it's such a powerful car they want a lot of torque management in the tune. As was said probably best way to get rid of it somewhat is with a good tune. I'm not ready to do that as I've got 3 more years left on the warrantee, wish there were some answers to get rid of it without a tune.

faz492

Custom dyno tune to solve that issue.

I get bucking from time to time from a start in low speed...super annoying. Happens in M mode in 1st gear. Delay/jump/delay/jump. If I let off the gas and try again or put into another mode, goes right away. Only happens on initial starts down the road, infrequently. Anyone else?

sdg1871

Yes I get the bucking too. It tends to happen if I'm in sport or sport plus and when I'm trying to take off from a stop or a very low speed and when I only am partially applying the throttle.
