M6 speed limiter: turn it off?
My M6 came preset to limit speed to 168 mph instead of 156. I've heard that the car can be set at the factory to limit speed to either 156, 168, or 200 mph. I don't know why the car was set for 168, but I'm glad it's not 156. Does anyone know how to get it set to 200 or just de-limited altogether?
Re: M6 speed limiter: turn it off?
M (or for that matter regular 6er) is limited. Although BMWs literature claims 155 MPH, many owners are seeing it at the approximate 168 level. If that is your indicated speed on HUD/Speedometer you can bet the real number is somewhat less due to the ~5% positive speedometer bias in all current BMWs. In any case, for Euro Spec cars BMW will raise the limit (not totally delimted) to match the speed rating of the tires. I am not aware they will do this for a US Spec car. And even if they did, I am not sure if they would on a car already delivered. Aftermarket tuners such as Active Autowerke can do this. Others such as Hartge do as well. Most will max it to your tire ratings although their literature may simply state "delimited"
