Today, I brought my car to 130mph and the engine would cut off and on and won't go above 130mph, for a moment I thought I have a E350. Is this normal for E550? The car is capable of so much more.. I begain to dislike my car... Is there a software mod like BMW Dinan that can remove the speed limit governor? I know you guys will have an answer for me.. Please give me some good news!! Love you guys!!!

Same Thing Happen To Me In My 05 E500......I Thought i was

There are many aftermarket places that can flash your ECU (I think it's the ECU) and remove this. However, any dealer work to the ECU will reverse any work that's been done to it.

It appears that MB has electronically limited the 550 to 130 mph according to Road and Track's road test - I have easily seen speeds of 140 or more in my 500 - perhaps there is an aftermarket alteration to the ecu that can change that - it's common on motorcycles to change those out - it's pretty much plug and play on the bikes - don't know about on the 550 or 500 - that is a real bummer -

See thats not right. The E550 tops 155mph and the E350 is 130mph along with the E320 Bluetech-130mph. Thats weird that it only goes 130. Get the special softwhare like said above either from a tunning company or a dealer can remove the govener. For real here 130mph? My 2000 C280 tops 130mpg along with all the other C Classes. I dont think this is anything major that needs to be done but a little bit plug and play from the dealer. Good luck.

Yeah, I thought I was crazy like BkE5Kid cuz the car can easily accelerate to 130mph, but then I can feel the fuel cut, then car start accelerate once I am under 130mph and cuts off again. Where can I get my ECU flashed? I lived in Socal..

steveberde, is your 500 ECU flashed?

I was really really bumped that my car got stuck at 130mph.. even my 225 horses BMW 530 can do 128 before it gets cut off, while the 2001 540 can do 155mph before the cut off, and our E550 with 382 horses can only do 130mph?? sigh.. long sigh.... I am sure you guys feel me..

steveberde

no my 500 is not ecu flashed it does not seem to be limited however like some - have no idea why - it's possible that the limiting came into play later than in 06 - don't know for sure- I am only repeating what Road and Track (see below) says in their road test -

Along with some rudimentary changes, all E-Class models now feature an innovative new Mercedes-Benz safety system called PRE-SAFE. Also, there are new versions for the driving enthusiast — the 507-bhp E63 AMG — and the mileage-conscious who reside in the right 45 states: the 27 city/36 highway mpg E320 Bluetec turbo-diesel. Slotting somewhere in between the two is the E550, featuring an all-new aluminum-block 8-cylinder engine.

Specific changes to our test subject include a larger, new-generation 32-valve 5.5-liter V-8 engine (the E550 replaces the long-running E500 model) that generates some impressive numbers. While engine displacement has been bumped up by only half a liter, power production increases mightily: 382 horsepower toward the upper reaches of the tachometer versus 306 bhp for the E-Class of old. Also, torque is increased and generated over a wider rev range: now 391 lb.-ft. from 2800–4800 rpm versus 339 at 2700–4000.

Yeah, I saw that when I was searching for the E550's top speed. I can't believe they limit the E63 AMG to 150mph.. Not that we use our car for racing, but it sure is better to go higher than 130mph when we need to. Still searching for a place to do the ECU.

Untertürkheim

Every E class sold in the US (320Blutec, 350, 550) can hit at least 250km/155mph without the lower limiter at 130 for the US market. This is one reason why I always take European Delivery, I bring the car in to a German service center and have them disable that pointless castration device.

Pekkle

So there is nothing wrong with my car cutting off at 130 then? Some times I feel like my car was defective. I have been searching on the website for some time now, some web says it's limited at 155, while some other says 130. and I am not sure who is right and who is wrong.

steveberde

Interestingly when the car was first introduced in 03 the electronic limiting wasn't in place on the US car according to this road test - see below - i swear my 06 is not limited - despite what is reported - don't know when MB NA started doing that - this is an excerpt from a road test of a US 03 E500

" Where the family heritage truly comes into play is in the drivetrain and chassis systems. The new E500 is powered by the same V8 engine found in other current 500 models. Outputting 302 bhp and 339 lb-ft of torque, the engine is mated to Mercedes' tried-and-true five-speed automatic transmission with Touchshift. The E500's top speed (electronically limited) is 155 mph, and 0 to 62 mph is reached in 6.0 sec. Acceleration is quick and smooth--the new 500 is 0.5 sec. faster than the previous V8, the E430--with 93% of maximum torque available at 2700 rpm and peaking at 4250 rpm."

actually seen several MB 550 M173 engine cars do 170 mph no problem without limiter,, there are plenty of videos showing this..

take out the spare tire and tookkit, and change the exhaust and should do
180 from weight savings and extra breathing

Polar Bear

You can meet up with Steve @ mbenznl.com to remove that. Or MARK CUMMINS could possibly do it for you (may try PMing him). If you were on the East Coast I could do it for you.

storm

almost anyone witha laptop and software can do the delimiting

is it not like a ecu tune or lowering,,
it is a value that simply is speed limiter , ON or OFF..
which you would choose OFF.. lol

any 16 yr old with a laptop and software can do it..

there are dozens of places that offer this service for $100-200
in most cities

Polar Bear

Don't think I would trust a 16 year old with a laptop with my E550.

It is set with the same software that does the lowering - SDS

Also, it is not set on or off, it is a variable that is changed from preset values.

I don't think Steve would charge $200 for this service - probably much less.

Untertürkheim

The funny thing is that in EU models it is a user-defined value in the menu, like the light delay.

Diesel Benz

You could have mentioned that is intended to cut the top speed if lower speed rated winter tyres are used.

The further to the North you go, the more winter tyres may be compromised on max speed over grip, I believe 190 km/h or 210 km/h tyres are commonly used, I guess 160 km/h is the lowest rating that exists.

NCE500

I think that 130 is plenty fast for the states, I'd be inclined to leave well enough alone unless you relocate to Germany and also upgrade to some W rated tires.

steveberde

OK so what's the real answer to derestricitng the car to electronically remove it? I would seriously like to eliminate the restriciton - how is it done and by whom?

Thanks

Steve

Most Non amg MB's are governed to 135 Regardless what anyone states thinks or believes. if its an Amg there 160 unless you have a tune which removes the governor and amg's may hit 200 with proper mods. my old video is below E500 with tune 160mph. i need a new vid lol.. Have more mods better times w/ No proof on paper

Dema

Right, limitation is related to tires rate. My regular E430 has 155mph limitation so can pass 130 easily, however E430 with sport package has 130, quite strange.

storm

ACTUALLY the AMG is limited to 150mph in the states,, unless you get the P30 package where it goes to 170, I believe..

storm

well I was joking with teh 16year old, but I have seen some of the drifter crowd young car enthusiasts with laptops do mods on Japanese cars
like the 370 Z and the Nissan GTR, and many others that are way more complicated that the mercedes software.. with hundreds of parameters..


and I have seen the star software many times at my dealers and other places.. and told by dealer and another mechanic that limiter is turned off
in a setting that is VERY EASY.. if you are remotely computer literate..

you have to remember, they made the star software for even mechanics to understand, and they sometimes are not the most computer savy people.. perferring a wrench to a keyboard,, luckily that is changing..
but it is the young car enthusiasts and modders that have revoltutionized
all the ECU mods, and modern tweaks like getting OEM stock cars to have 400-500 HP,,

places like SKUNK etc do great track proven cars..

Polar Bear

The settings is actually not available in standard STAR - it must be running in Developer Mode for it to even show up.

Not much in the way of "tuning" in STAR, but this is one thing you can change, on the gas engines at least.

Your Owner's Manual should tell you what your car's speed limit is.
Please find information I got for my 2005 CLK 500 below:

Under Operation - Driving Instructions - Tire speed rating section.

CLK 320 with Appearance Package

- Your vehicle is factory equipped with "W" rated tires, which have a speed rating of 168 mph (270 km/h).
- An electronic speed limiter prevents your vehicle from exceeding a speed of 130 mph (210 km/h).

CLK 500

- Your vehicle is factory equipped with "Y" rated tires, which have a speed rating of 186 mph (270 km/h).
- An electronic speed limiter prevents your vehicle from exceeding a speed of 130 mph (210 km/h).

CLK 55 AMG

- Your vehicle is factory equipped with "W" rated tires, which have a speed rating of 186 mph (270 km/h).
- An electronic speed limiter prevents your vehicle from exceeding a speed of 155 mph (250 km/h).
