Speed Limiters on Non EU E90s?

At bmwusa.com and other (related) sites I read about 325/330s being limited to 130 or 140 mph. Is that correct?

Having driven about 1000 miles I tried the thing yesterday. 255kmh (158mph) in 6 was 'nothing' actually. Not like the former E46 330i which felt astmathic beyond 230kmh(140mph)

The E46 M3 was another story though, that one always kept on flying towards 275kmh(170mph) in 6 before the engine was 'shut off' kindly

This car is great. Beyond 5000rpm it feels and sounds ALMOST like an M



Edit: And this sunday we're about to go to the Nuerburgring-Nordschleife(where the E90 was born actually ) to try it.
Pictures will follow after that(I hope )

The cars in south africa are all limited to 250km/h. Reguardless of sportspacks or anything.

The only poeple that drive those rediculous speed on our roads however are the ministers of safety and the ministers of transport. Wonder how they never get fines, and I ALWAYS get for doing 10km/h over :/

Errr, Dinan has chips for the E90 already? Wow, that was fast. What benefits does Dinan claim for their chip?

In general it is my understanding that in Europe, non-exotic cars have a speed limiter built into the car that corresponds to the speed rating of the tires that the car was built with. Said speed limiter is typically set at 128-130 for "H" rated tires and 149-155 for cars with performance rubber. That same rule now applies to the E90 here in the U.S.A.

Back when I was working with MB-USA, they were dealing with a tire issue on the S-Class. Said issue revolved around the "Z" rated tires (IIRC) that came as standard issue on the 1992 and later S-Class cars. Unfortunately, for those of us who lived in colder sections of North America, those tires would "Flat Spot" when cold, and require a number of "thump-thump-thump" miles to warm up before they would start rolling smoothly. On of the options that MB-USA offered the owners of affected cars was to replace the tires with a set of "H" rated All-Season rubber along with a modification to the ECU to lower the top speed to 128 mph. The logic behind this option was rather obvious, I mean, how many S-Class Benzes have any of ever seen flying along an Interstate at speeds north of 128? The odd AMG Hammer or two? Yup, that's what I thought. Anyway, you'd be surprised how many folks refused the offer simply because their car "wouldn't go as fast" (conveniently ignoring the fact that their car hadn't even seen 100 mph yet, much less 128 and beyond).

Best Regards,
Shipo

I recently read an article in Eurotuner (crap magazine) with Mr. Dinan himself. He mentioned that the new BMW engines will be very difficult to extract any extra power from them using software. He said that BMW has built an almost perfect motor. Technology has gotten to the point where there is very little variables left to 'tinker' with. He also mentioned that 'bolt-ons' will be the only area that people will be able to add any performance to.

Personally, I agree and disagree with him.... I agree that BMW has made a fine motor and I don't believe that there is going to be any more power to massage out of the motor using software. I disagree, however, that bolt-ons will be the answer. I have always thought it was a load of crap when aftermarket companies claim all this extra power from using there $1500.00 exhaust system. That's basically saying, "BMW engineers make the best motors in the world, but they really screwed the pooch when they designed this pipe that goes out the back of the car..." Think about it, do you honestly believe that BMW didn't tune this car as whole unit, and not the individual parts? The only reason for getting an exhaust these days is if you want to improve the sound.

I personally think the only way to get anymore power is with forced induction. Of course there is a substantial price to be paid for that.

@voltron: Agreed.

Or buy a M.

The 343BHP M3 engine was SUPERFANTASTIC , this 3.0 is FANTASTIC. You see the difference?

335ci would be great.

Of course.... How could I have forgoten about the best naturally asperated motor of all time. :rocks: :rocks:

Robin, have you owned any M's in your day? If so, I would like to know if they consume oil or not? I had read an article where they were testing a brand new M3 with only 3000 miles on the clock, and they claimed it consumed about 1.5 quarts of oil every 5 to 10 thousand miles. Was this statement made falsely because it was a new brand new car/motor, or do all M's consume oil throughout their life?

Voltron, I owned a 2002 E46 6sp manual M3, last year I sold it

No oil consumption whatsoever and I did drive it hard(when engine was warm)

Superb engine response from even 2000rpm to redline 8000.

This is me on a small track a little sideways, last year

Unfortunately, if I'm "caught" driving at this speed here I'd likely go to jail and lose my license for a good period of time. My understanding is that anything above 120 mph, you will lose your license for at least 30 days.
