i have a clk 350 and the top stop speed for the car is 155mph, but when i push my car to that speed it sticks on 135 mph and won't push any further. I hear that it is because of a computer limiting it. I was wondering if anyone would recommend any shops around Torrance, CA to remove that "limiter".

I am pretty sure the limit on the CLK 350 is because of the tires. Mine are not V or W rated and I am betting yours aren't either. Before changing the car to exceed 135, make sure you have installed tires that can handle it.

Only TWO ways to remove the speed limiter

1 Software from a decent tuner..(That WILL VOID the warranty on the ME control unit)

2 Remove it via the SDS aka Star (DEVELOPER STAR) Not the dealer sds star
contact steve at MBENZNL@hotmail if you want it done via the sds ..He will be in So Cal next month

And the prevs post is correct You WILL Need higher rated tires if you are going to play faster

Hello
Have you the instructions to remove speed limiter on a 2003 CLK 55 AMG with SDS (DAS/Xentry 09/2012 with developer mode) ?
Best regards

Rudeney

Go into the ME control unit coding -> "Development Data" -> "Control Unit Adaptations" -> "Control Unit Adaptations (Variant Coding)" -> "Implicit Coding", then find parameter "0224 bis 0231". It's the VMax parameter and it can be set up to 240km/h (150mph).

NOTE: USE THIS AT YOUR OWN RISK!

When I got my ECU tuned, my tech said there is no longer any speed limiter. I have never been in a situation where I could actually push the 55 to max speed. Too much of a cruiser...

Rudeney

Yes, and ECU tune generally removes the speed limiter completely because you are literally writing a whole new program to the computer that simply does not have a limiter. Using the stock ECU code, there is a limit, but as Mark said, it can be increased from the stock 135mph using the "developer" version of SDS. The max appears to be 150 or 155mph. The dealers don't have this, but the hacked Chinese clone SDS/Xentry "C4" systems sold on eBay generally are the developer version. If not, there is a guy that sells the developer unlock key for about $40 (he posts here occasionally).

I tried this way but there is nothing under 155mph (250km/h). I would like to remove the limit or to put it at 280km/h or 300km/h for example.

Rudeney

You can't set it over 250km/h with SDS. For that you'll need an ECU tune that totally erases the limit.

So bad

Tex jai fait la modif de mon ECU chez Powerchip en haute savoie. Regarde si ils sur Paris ou dans ta region.

Tex5

Oui mais je pensais qu'on pouvait le faire avec SDS en mode dev.

LOL my old thread is still alive. To answer my own question. You can remove the high speed limit with a reflash or custom tune ECU.

Tex5

I tried to find how to remove/upgrade the speed limit. In module ME 2.8, I only found this in dev variant coding :



But there is no value above 250km/h which is the speed limit I want to up. So any solution except reflash ?

Rudeney

Tex5, that is correct. You can only go up to 240km/h via SDS, even in "developer" mode. You would need an ECU reflash (i.e. custom tune) to go beyond that. Most custom tunes generally remove the limit completely.
