Either way, I get along great with everyone I have met in person from this forum. I think people are just way to sensitive when it comes to the forums. In my circle of friends we bust ***** and tell it like it is. I am sure most of you guys are the same way in person yet the forums make everyone so delicate. This is why people should attend track events. Meeting the person behind the forum name works it all out.
Back to the topic please....
I would like some more people to come forward about the C63 and limp mode on the track. If they could list the conditions as well as the year of the car maybe we can narrow it down to either a problem or just a select few who have had problems. hughes mentioned above he had no issues in the many track days he has used the car. Why didnt he have the issue? Dad's has reported limp mode in his C63. The conditions in FL are terrible to say the least. Like I said before, it seems like a condition issue. How do M3's and the other cars mentioned perform under the same conditions as Dad's car. Yes the manifolds might be glowing red but that doesnt tell the whole tale. Maybe the humidity is the problem. Heat + Humidity is a killer for cars.

When will people realize they are driving a performance sedan and not a track car? You figure the air conditioning and plush leather seats would have given that away. 
AMG did a great job on the car and it does exactly what they intended to. Go fast and stop quickly. If you wanna hot lap it like an F1 you are going to have to do some modifications.

No one called the C63 a dedicated track car, however it is advertised as a sports car and comes with a lap timer. What's that for? Timing the run to the local fancy coffee shop and back? Ostensibly it is targeted at an audience that includes those --such as myself-- who want to take it to the track every so often.
I suppose a M3 is not the same? Or a Z4MC? I've owned both and both had air conditioning and leather seats and both ran just fine on the track for as many laps as I've run my C63. No one expects these cars to perform like bona fide track cars, however I do not expect my "sports car" to hit 120 celcius in normal city driving and 135+ on the track and then kick me out of manual mode. This car was built to at least withstand light to moderate track duty otherwise it would not come with its massive brakes and LSD. It is a M3 / RS5 competitor and it should be able to get a few laps in without overheating or me constantly worrying about it overheating. I do not think it is advertised as a drag racer as you allude.
Edited to add car info.:
2012 C63 AMG Coupe with the Performance Package Plus (P31 + LSD in Canada)
Track: Mosport - temps were in the 125 - 138 range. Ambient temp was arond 20 degrees celcius.
I have the car in current 10 degree weather hitting 115 - 120 celcius in city driving.
The car builds up too much heat under its hood. Better cooling and vents would help greatly I think.

2012 C63 coupe
In case some haven't heard... It as been reported on the AMG PL that MB has a fix. Raising the limp mode threshold as it is too low from the factory. They also say this is perfectly safe as it is very conservative as is. Apparently dealers can re-flash cars now to correct. I know in my case, my car was running only slightly hotter than limp mode cut off so this should fix it.
It's great that MB took this seriously and dealt with it.

Yes
You know... thinking about this, if this is the case then why put a vented hood + larger oil coolers on the Black Series? Also, when my car was running at 135+ Celsius, the tranny was shifting erratically, i.e. it would take forever for shifts and it was obvious it was not happy.
All the flash is doing is raising the current "limp mode" parameters so the car can perform totally normal under high heat that is still deemed safe by MB.

Check out Dec. issue of Automobile Mag. Front page.
They did a comparison between C 63, M3, RS4 , Boxer
The C63 came in last because it went into limp mode after three laps on the track.
Somebody should be fired at AMG

Yup... I really want to forward that article to someone at the top of AMG; although I suspect that person would have it... and not care. It was only 0.01 off the M3 with its ****-skinny stock tires - and don't think it was a HP track.

My first service is coming up in about 25 days so I'll ask when I go to mine. Autobhan is about 2 miles from me but I always get a bad feeling from them so might take it back to Smythe European where I got it from in SJ.
