My f36 440i came with run flat tires from the factory and im assuming its the reason my car is limited to 130mph. I recently switched the run flats to some Michelin pilot sport 4 AS and was wondering if it was possible to have that speed limiter removed?

[Wires]

It's the rating on the tires, not RFT's, that govern if there is a higher speed limiter. My car came with the msport package and RFT, has the higher limiter.

You can code it out if you are running tires capable of the speed.

[sokyoto]

What was yours limited to? And is there a way to code it out?

[Wires]

Not sure, 155MPH? It would be what the m-sport package came with. You can code it out as well.

[sokyoto]

My car came with the M Sport package aswell but is limited to 130. What can I code it out with if you know?

[paul e]

I was told there is no way to code the speed limitation, I’d be more than interested to know how to do this.

Wtf? Why would BMW limit a B58 to 130 mph/210 kmh? In what retarded country is that? On the German Autobahn, at that speed you would get high beam flashed from behind by a snail. In Europe, regular German cars are limited at 250km/h. As a standard, cars are delivered on tires with a rating that exceeds the top speed of the car. As it should be. E.g. my 320i has a top speed of 235kmh (not limited, that's just when the air and roll resistance becomes higher than the engine output) but the tires are rated at 300kmh.

In the US i guess I dont really know why but I cant find a definite answer to get rid of it

That sucks man. Maybe BMW North America can help? Maybe if you sign a release that it's for track use only? In that case, I would only remove it once all warranty and goodwill has expired. I read somewhere that Bootmod 3 may also be able to do this, but of course whether that's an easy fix depends on your model year.

It can be done with VO coding.

Because that's what the OEM tires were rated for. If you want 155 MPH capability order your car in a version that has 155 MPH rated tires as OEM.

ECU flash will also get rid of the speed limiter when configured to do so. Tools such as bootmod3 or MHD can remove the speed limit.

What kind of fake ass OEM tires are y'all getting in the US? I cannot even think of any OEM wheel/⭐tire combo for a 440i that is rated lower than 250km/h? That's some Ebenezer Scrooge ass shit y'all got.

[Billfitz]

When the maximum speed limit in the US is 85 MPH the actual need for tires rated at more than 135 MPH is zero for other than track use.

Why do some Europeans always insist on phrasing things so obnoxiously?


There is no where in the US that driving 130 mph is actually safe except a track. And this is easily coded out.

Point proven. Dude you're an ass. US has the same and probably better tire availability as where you're located.

Different climate as well. When you live in Florida, can fry an egg on your dashboard in the summer, tires that can survive those temps and meet speed ratings are a bit more challenging!

There is really no difference in tires sold in the US vs Europe.

Here is Tire Rack for my F36

[monster6a2]

Isn’t MHD capable of removing vmax?

[sokyoto]

Im really not sure thats why Ive been trying to figure it out😂 But I think bootmod and mhd are capable of doing it

[LA430]

Can confirm MG flasher has the option to change speed limiter. Protool also has the option VO code the vehicle and change speed limiter as well.

[Boznien]

A tune from bootmod3 will remove the speed limiter.

As others said, make sure your tires are rated for the speed.

Speed safely

[eluded]

Most high-performance tires, such as the Michelin Pilot Super Sport (MPSS), are rated (Y) for speeds up to 186 mph. I find the additional traction and cornering performance essential. In contrast, tires rated for speeds up to 135 mph are often subpar.

Back to the OP question, you can get rid of the speed limiter with most ECU flashes (BM3, MHD, etc) but you might shoot your eye out.

Hey bro, no reason to get personal. Chillax!
Of course I know that the tires are available in the US. You're just proving my point. If the car is a 440i it's well capable of speeds over 250kmh, so BMW is being scroogy for fitting OEM tires with a lower speed index.
Doesn't make sense to make a car with an engine, drive train and suspension built for speed, and then install inferior tires so that those become the bottleneck and you have to limit the top speed just because of cheap ass tires. That's almost as retarded as miles and gallons and Fahrenheit.
