Many tuners over here offer just the SW to take of the speed limiter from customer cars. Many charge upwards of 1K euros for that. A tune will run you more
over here(1.5K euros plus).
I know for my German tuned 135i(US specs), I have seen speeds as high as 283 kph via my GPS(Navi). The speedo was pegged. And... I think my car will go faster... I just have not found an empty enough Autobahn. Stock the speedo said I was doing 250 kph while the same GPS said I was only driving at 240 kph!
The funny thing with driving (really) fast is people are not use to driving that fast. And to be honest some just do not remember how fast they were really going. I know I have run into many a M3 (e9x)owner who say there M3 will do 186 mph, and I tell them BS. Then I asked them how accurate their speedo is and they have no idea. BMW speedo's will read at least +5%. You really need a GPS and an empty autobahn.
Also... unless you have an Autobahn in your back yard... you are just not going to see these kinds of speeds. I guess I am spoiled by having unrestricted autobahns in my backyard. You can drive as fast as you want. Here is a question... I have gone WOT for so long, that all the vacuum is depleted in my HVAC and the vents default to the defrost while driving V-Max. I bet not many people know that will happen. I think you must drive longer than 30 seconds at V-max for that to occur.
As soon as you lift off and generate some vacuum, the center air vents will work again.
And the other problem is the hood of our 1er's gets really scary at speed. The front edges start to peel up a few inches after 240 kph and up. I know I was talking to a guy who works at BMW AG... he has a friend
who works at M GmbH... he told me his friend said that was the main reason why ///M will not make a "drivers package" (speed limiter bump up to 280 kph) like they do for the M3's and M5'/M6's. He said that the hood on the 1M could open at very high speeds. So that is why 250 kph is it from ///M. Btw the F20 have TWO places where the hood latches - so this problem has been "fixed" for the new M2.
Dackel - are there any thoughts on a patch for this? It's unlikely I will reach these speeds, but my Teutonic DNA makes me cringe that the possibility of a hood launch wasn't addressed.
