Coupe Top Speed Limited?
I have had the Coupe for almost a week now and I went for a high speed run yesterday and top'd out at around 135 downhill...I have a stick. Is this everyone's top speed? Can I change the limit? I am not used to having a limit, this really sucks.
Thanks,
Erik

yes the coupe is speed limited to 135mph. I think there is a tuner that will remove the limiter but its way $$$. From what I have heard the coupe will do 148/149 without the limiter.

Well atleast its not just my car...does anyone know which tuner or what they need? I can get access to the MB ECU kit, so is it an option or does it have to be physically mod'd?

i hope you're breaking it in better than that.

Take Ferrari for example...no Ferrari leaves the factory without something like 1,000 miles (or KM, I don't remember which) on it. The car gets beat up on the test track for days before the owner gets it...

The C230K, and most other cars sold in the U.S., are governed at 130MPH. Some are limited at 140MPH. The coupe's unrestricted top speed is 149MPH, but you will pay a tuner big dollars to get your ECU tuned for that additional 19MPH. If you are willing to pay those monies, it would make sense to do a pulley, exhaust, intercooler, etc. first to fully realize the net gain.
I speculate you might see 155-160 with a really beefed and tuned system.

I still need to know if the ECU tuning would be software or hardware based. Does it physically need to be modified or does it need to be reprogramed?

The top speed of 149mph is GEAR limited, it is redline in 6th gear. The coupe is software limited to 130mph for lots of reasons like tires that are H rated and insurance liabilities. To reprogram the ecu you will need to find someone that knows MB code, it ain't standard from what I hear and without knowing what factor you are messing with you are asking for trouble. There is a German company that will delimit your chip for around $2k with a power upgrade kit good for about 50hp.

As far as the gear limit is concerned...I was afraid of that...but 149 is close enough to 150 for me.

According to the math, the gear limited to speed is 149mph. Using Road and Tracks figures the top speed is 153mph. This is using a 6000rpm limit which is realistic because power falls off above 5500rpm. See what numbers you come up with doing the math.

MKB and several others will remove the Vmax, but usually they are talking about the 250km/h Vmax on faster cars. Not sure if it is the same procedure to remove the 130mph Vmax on US cars.

hmmm
Wows... that's pretty quik hitting up those fast speeds at such an early stage. Also a good point on how cars were tested before the owner gets it.. but me being paranoid in that area... I waited til I rolled out the 1000mark.. hehe. It just crossed that 4 days ago.. and I've been quite happy.

To the second part: You can never drive 150 ALL the time, but there are plenty of times that you can. Buy 'Mischief 3000' and see a car go 203mph on public roads...and see one get pulled over doing 187 in a 65.

Has anyone just tried swapping out the ECU in favor of a European spec ECU? Might be cheaper, and maybe you'll pick up that missing 5HP that the Euro cars have over the US spec cars.

If you don't want to drive to the full potential of the car, then don't try and remove the limiter.
