For sound freaks and limp mode lovers
Took the C63 Coupe to Motorsport Ranch in Cresson, TX over the weekend for an MB Club event, designed to allow beginners to experience driving on a track.
Picked up a new GoPro 3+ Black the day before, and mounted a couple external mics inside the rear bumper against the frame..right above the rear tailpipes. If you like burbles and pops, here ya go.
As a bonus, even though it was 60 degrees outside, the car overheated twice halfway through the second session, so i pulled off and cooled down a bit before finishing up. Here's both sessions. I know I can't drive, but it was fun nonetheless.
Limp Mode - car pulls power at 0:12 and gives it back about 0:35
Solo Session 1

Won't let the video play in the thread because it says embedding not allowed. But I looked it up on YouTube. Looks like you had fun! What mic setup did you use? Were you in M or S+ mode?

Hey, I was out there with you! I was in the black C63. That was a nice track. The surface was very nice and the layout was ok. Now that I've been to MSR I can say that I like the layout of ECR better - but their surface is fairly poor.
My 2010 did not go into limp mode at all - and I was running as hard as I could 100% of the time. I managed 5 sessions on the day. At the end of the day I was out with the 'faster' group then rolled right back out with the 'fast' group. Two 20+ min sessions back to back and no limp mode. I kept mine in S mode the whole time. In early Sept I was at ECR (~97 degrees) and I tried S+. It was fun, and loud, but I spent too much time in the upper RPM's and I did go into limp mode there.
It was nice to meet you out there.

Yeah I saw your post in the other thread about "anyone gone fast lately," I replied but I don't think you saw it. We never were in the same group, I stayed in the beginner session and the other White C Coupe didn't run except during the lead and follow sessions. The facelift cars with the MCT transmission seem to be the ones going into limp mode. The pre-MCT models like yours all appear to be running as expected or at least much better.
I watched a video from a yellow Lotus that you passed and looks like you were clocking about 1:33-1:35 per lap. That's right where I was at 1:34 per lap. Was a great day!
By the way, just saw your sig mods, I commented as you left in the advanced group that your car sounded like it had headers, I must have been hearing the res delete! Sounded good.

I ran S+ mode the entire time and Sport Traction for both sessions up until it went limp. When I went back out, I turned off traction completely, but always left it in S+. In the video once it switches to HD mode you can see the temps. Limp mode kicked in at 287 degrees and then once it cooled to 285, power was restored. Never gave me any indication on the dash that it was in limp mode at all, no warnings, no lights, nothing. Didn't even realize what was happening until the next time around the track in the same spot, it did it again.

That Lotus was scary to be near. Each time that I was on his tail it seemed he was 'driving his mirrors' and was all over the track and/or about to spin out driving so hard to prevent a pass.
I haven't logged on for a few days and did not see your post in the other thread. No LTH for me at this point just the r delete. I love the sound. Great mod for $90.
Where did you see the video - plain ol' youTube? I videoed the lead/follow session then messed up later. I must have got out of sync with the start/stop button as I ended up with no track footage and two fifteen minutes videos of our cars parked in the line as we were all up in the classroom. I foobar'd that one for sure.

Weird how you guys get LIMP modes...I've beaten my 09 to hell and back and never once has a LIMP mode popped up...I mean I've had it running near 120C but rarely ever does it go above 115C and I beat on it...I hope when I get a 2014 or 2015 in a few years I don't have this LIMP mode issue...Anyways best of luck! Good video...wish there were some tracks in my city

Yeah, that's what I've heard, but it seems to be a pretty extensive changeover, some cutting required for air vents, some new lines custom built...did you have to go through all that?
#14
Yes thats my thread your referring to. A good shop should be able to do it once they know whats required. The guys that did it for me had never done it before and used their expertise to get it done its not anything crazy no body modifications at all just custom oil lines, some shaving and compressing of the new black series air duct for oil cooler and thats pretty much it. The trans cooler is a direct bolt on no modification required at all. If your going to track your car or push it hard on the streets in the TX heat it might be worth it some time down the road limp mode is very frustrating

That's the thing, I probably would only track the car once or twice a year so it's a matter of deciding if the investment is worth it since AMG is not offering a solution. Would you be willing to share what the total expense was?

Nice driving! I was amazed when I saw you pass the yellow Testarossa. That was my dream car when I was a teen. Amazing how the technology of cars evolve...
The reason why 2009-2011 C63 don't go in limp mode is because of the transmission. Before 2012 the C63 used the 7G tronic speedshift, and 2012-2014 cars use the MCT transmission, which is prone to overheating. I believe that there was a SW update in 2013 to fix partially the limp mode issue.

Awesome footage (and sound). Thanks for sharing.
We could use more threads like this! Love 'em.

The software update was issued late last year, but my car was a March 13 build and already had the most recent update. After speaking with my Benz shop foreman, he contacted their regional Tech advisor and was told there is no additional update. So, looks like Black Series cooling should have been on the options list...or...dare I say...standard?

Those Ferrari guys weren't really pushing it I don't think, and everybody was pretty much brand new at driving on a track, so I won't take credit where it's not due, but it was a lot of fun passing Ferrari's, I will DEFINITELY say that! Not my fault they didn't want to go faster

Not exactly. I was trying traction mode completely off, and almost lost it in that corner right before where you're talking about, so i was fishing for the traction button to get back in sport traction (see the center dash screen changing) but accidentally hit the big COMAND knob. They have us tune to 88.9 FM so they can talk to us, and I was afraid i'd tuned away from it, so i had to then fiddle with the radio. So yeah, LOL but not intentionally.

awesome to see some of yall go out to msr. Hopefully the wife will get ours out there, and ill take the supra when it cools down some more.
To further your 7g talk.... v12's have never had the 7 speed up until this year. It wasnt necessarily that the mct couldnt handle the power it was the rest of the transmission but ever since they've gotten them mated up with the 5.5L biturbos they figured out how to make them hold up. All the previous v12's up 2013 had the old 5 speeds with the old fashioned torque converters. The mct can actually shift faster and is more efficient since it does a full lock up unlike a converter that is always slipping somewhat. The 7speeds have come along way.... starting in 2003, later getting the throttle blip downshifts and ofcourse the mct. obviously there has been vast improvement over the years with the valve bodies, software and hardware. Its not often anything actually fails in the 7 speeds other than the contact plate/module which is one piece with the speed sensor. I dont really know why the mct's like to overheat on the track but 100* texas temps dont help.

My thread and I'm jacking it. You local guys, JumpinJim and I are going to Crandall Friday eve for the last evening test and tune of the year before they switch to Sunday afternoons. He will have either his M5, or SL63, or both. I'll have the C. Clark Kent, maybe you and I could duke it out for fastest tune. I'm running OE and I see you're on Eurocharged. Would be interesting to see.
