I have a '13 C63. The car will not so much as chirp a tire.

I've tried every permutation of ESP and MCT settings. Tires are stock and the car is 100% stock.

I assumed ESP off would result in significant wheel spin. There is ZERO wheel spin... from rest, from low speed roll etc etc etc.

It seems as though there is some pretty wicked torque management at work.

I am a very experienced driver with years of drag racing and track/DE/TT experience including NASA TT records.

I have two questions... for other owners of '13 MY cars, if you turn ESP off and set the MCT trans to S+ or manual mode and floor it from rest do the tires spin?

Assuming this is torque management, how do I eliminate it?

I wish I had this problem.....being a bit too aggressive with the throttle in comfort mode will cause the tires to chirp and the ESP to come on.....

It's really not a good "problem".

Any ideas/suggestions are very much appreciated.

turbo...I read your myth lol. Tires not spinning on this car is a legend.

I have the same problem

ahah

Sadly, I fully expected this sort of response.

I can't really help that I didn't post on the MB forum until I owned an MB.

I regret that you can't take my post seriously or add anything useful to this thread.

In all seriousness, if anyone has any ideas or suggestions I really appreciate it.

I really believe it's torque management.

I was joking, but joking aside. Most of us can make the wheel spin even to the 40mph. I really do not know how youre not spinning.

turbo8765

Fair enough.

I too might think my post was odd given the circumstances... well over 400 ft-lbs and a 255 rear tire (280 TW) should equal smoke and carnage. But I assure you, for the life of me I can't get it to so much as chirp a tire. I even tried dyno mode to see if there was an electronic nanny that might be disabled but I got the same result.

I've got a 13 Sedan, and my tires go up in smoke if I try to punch it from a stop. Heck, the tires break loose if I try to punch it from a 40mph roll!

You might want to throw your car on the dyno just to verify there are no issues and your power is getting to the ground properly.

I think we all just find this a bit hard to swallow because of how little effort it takes to make the tires squeal on these cars. I would love to see a video of you flooring it from a dig with esp off in sport/sport+. It's nothing personal, I just simply don't believe that you can't possibly get any slight wheel spin...

turbo8765

Stock as well as modded?

This pretty hard to believe. Last time I used race start the car chirpped shifting into 3rd.

Actually, I also am surprised by the lack of wheelspin, and mine is OE tuned. Before this car I had an 07 E63 with the same engine, and it would rarely do anything but grip from a stop. When the weather gets cooler, it's a different story, but in the dead heat of summer, it's rare that I floor it from a standstill and get any chirp or spin at all. Amazing as it is. Also, that picture above clearly shows the brake was being held to get the wheels spinning by the pool of tire dust found at the start. It's rare to find any videos on youtube of people NOT doing rolling burnouts by starting with the foot on the brake. It's just not a tire spinning engine in my experience having owned two so far.

And I may also add that the MCT transmission is incredibly weird. Having spoken with others that have the same transmission in more than one car, they confirm the weirdness, so at least it's not just me.

Merc63

Drove some newer c63s in the amg tour, they would barely spin the tires either.

My buddies 09 same thing.

It's adaptation, you need to bag on it more.

After my buddy got the car used and bagged on it for a bit, it started to come alive.

turbo8765

Could be adaptation but I believe it's torque management. I've owned and driven a lot of fast cars and I feel like the a bit of timing is being pulled in first and second gear. Particularly in first gear below 3500 revs.

fly2nite

At risk of exposing my lack of intelligence, how does one read timing precisely? I'm going to do some data logging this Friday at a local drag strip because I think I'm losing some power up top, but I haven't yet figured out what exactly the timing map should be, or what other indicators I should be watching. Sorry for the thread jack.

JeffDL

you have too much traction when you start breaking parts. you need some go fast parts.

turbo8765

Reading timing and knowing the timing targets or maps are two different things. Timing can easily be read with most OBDII loggers. Timing tables would have to be provided by your tuner (not likely) or sourced from MB (or a tuner who's read them from the DME) if you're car is stock. May be able to find the stock tables with a google search though I've found MB related info to be a bit sparse.

Mark C63

I have a 2012 and I have experienced the same thing as the OP. I turned ESP completely off, put it in S+ and floored it from a stop. All I did was shoot like a rocket through the intersection. No tire slippage whatsoever! Needless to say I was very surprised by this from what I have read on these forums.

Ezec63

thats very weird ... As suggested earlier i would get the car dynoed and make sure its putting down the power its supposed to and their arent any air leaks causing power loss. I have a 2012 c63 coupe with MCT as well and when stock on stock tires it was almost impossible NOT to spin the tires from a dig or low roll. I now have a bunch of mods ~470 whp and bigger 275 nitto nt05's that have a much softer/grippier compound and its hard to launch it out of the hole without wheelspin unless its hot out the tires are hot and i modulate the throttle. Very weird

Wat??? My tires chirp with ESP on going around corners...Hell when I put ESP-Sport mode on if I punch it to hard I'm laying rubber...Took it entirely off once and left about a 50 foot line of rubber ...I do beat on my AMG though...not like beat on it but you know what I mean.

This seems odd to me as well. If you're having an actual "torque management" issue that would seem to imply one of two things. A, that ESP is still active (I can peel rubber even in Sport mode, much less ESP fully off). Or B, an actual fault of some sort. If you're suspecting a torque management interference issue, then OBD should throw a Check Engine light as a result.

There is a third possibility, and that is you're not using all of the throttle. I'm going on the assumption that you do actually know how to drive though.

A potential third factor could be the tires that you're actually using (mine came with Yokohama, though Conti's and Pirellis seem to be the de-facto standard). Still, short of a proper drag radial I'd be surprised that any tire would hook up that much that you couldn't light them up at all.

Hmm....makes me want to find a quiet industrial park nearby and confirm all of this.....
