Coupe Top Speed Limited?

Thanks,
Erik

Erik

you were going 135 on a high speed run and the car's only a week old?
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?

its an electronic thing that has to be reprogrammed.
I will let the board know what I come up with.

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.

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.

why do you want your limit removed. when can you possibly drive at 150 all the time.
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.

I was under the (perhaps mistaken) impression that there was a difference in how HP is calculated in Europe vs. the US so that in actuality there is no missing 5 hp.

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