Speed Limiter

Is it possible to take of the speed limiter in an 06 s500? If it is, where can I have it done? Your help would be appreciated. Thanks!

I hear a Renntech can help you flash your ECU and remove the limiter.

somethign doesnt make sense with slr n8.. i dont think a 2006 s500 has more hp then a 2000. after all its the same engine as a 2000 s500..the only upgrade is the transmission that might help hp.. somethings not right.. evn with the modification u say it has..idk i question it..."Blk/Blk, Nappa Lether, AMG Rims, AMG Bumper, AMG Front air dam, Tuned up engine, sohc, liquid to air intercooler, MB Turbo Charger, all mb,382 hp, 0-60 in 4.6 sec., Heated & Ventilated seats, Bose surround sound, Comfort Pkg, Massage feature, Keyless Go. " i didnt know mb made a turbo charger for an s500 but nooo wayyy can it give u that it be alot more.. since renntechs mods are like 1200$ for ecu upgrade and 16k for supercharger... somethin is not right or please correct me if im wrong.

The dealership I bought it from had this car fixed up as a show car. Later on the dealership used the car as a demo car because many wanted to test drive the car. they did this to show off the s500's power. It was stopped being used as a demo later on. they wanted arouse the people who were looking forward to test drive the car. They put 15 grand worth of extra stuff in this car. It was expensive, but after the s550 came out they did the same stuff to it. The price of this car was marked down significantly due to the new models coming out, and the fact that the car was a demo. Hey, that's what the dealer ship explained. I asked them why this car was different. This what they told me. The 0-60 is around 4.6. I timed it with a watch.

Turbo S-class? Show me. With the 10:1 compression, you're not running anymore than 5-6 PSI, but I wanna see this.

Oddly, that 4.6 is exactly the 0-60 time for an '05 S55 or S600, which have 493 HP. You'll excuse the skepticism, but your claiming of that time and 382 HP don't seem to gibe. And your claim of the exact HP of the totally different S550 engine is another coincidence. And your claim that it's "all MB" and turbocharged is a tad suspicious since MB has never turbocharged a gasoline V-8.

You might want to pop the hood and see just what the dealer did do. And have the watch checked.

Who makes an after-market turbo for the M113.960? Never heard of such a thing.

i agree with you whoover..but if you give a quick thought a cars torque is usually higher then its ammount of hp for example i mean 302hp... stock is a s500 right.. and 339 torque. and 0-60 6.7secs some claim 6flatt its possible. so its kind of believable but the thing that makes it sound like something aint right... its a mb turbocharger ..it cant be renntek supercharger... cuz that doesnt match wat a renntek would give you. take pictures of under the hood... we gotta see this... or u might have an 2000 2002 s55 engine in your 06 s500 which that engine hhas 354hp and if you do an ecu upgrade it gives you 384 but idk..very sketchyyyy..pics would be very helpfull....

mercedes would never never never never turbocharge any model other then amg's or v12s..dealerships could get in trouble for doing that...

i think your stealership lied to you if they told you that... but find out exactly what they did... if its possible ill do it mine...

These S500 cars pull like a raped ape right up to 130....then that damn limiterjust grabs it. Mine does exactly the same thing. It's frustrating enough...but it's not worth $1500 + to take it over to Renntech (about 20 minutes for me) to get a re-flash.

When it's warmed up pretty good I've been able to get it to pull harder than that. I guess I've just always been paranoid with these ECU upgrades. I have to snap out of it.

Ken...when I was in High School every body wanted a GTO, 442, SS 396/454, etc. I remember all of the road tests on those muscle cars from the 60's did real well to get near the mid sixes 0-60. Our cars do it in 6 flat on a bad day and in the high fives on a good day. I still think anything under 6.5~7 seconds is damn fast, especially for a 4 dr sedan!! But then again...I'm old school.Enjoyed the video.

Jesus christ Ken, that's a fast S-class. I timed it roughly, and you sprinted to 60 mph in 5 seconds??

Looks like the S500s are way quicker than the S430.

Edit: I'm watching that video over and over, is that unedited? Unless our speedometers are way off, you got to 60 mph in under 5 seconds. Damn!

I like that hard pull. I still think I can do better though. Only mods - K&N filters, thats all. It's not really a mod. Everything else stock. From the camera to youtube.
