GB_V_MAX_KMH --> Value 01

Any insight ??.. surely it's not as easy as that ?!? bit loathed to mess with the setting because I'm unable to test it as not due in Germany for another month or so

There is another value

But i believe this is the value at which it wont kick down a gear if you exceed ??
If your car is speed limited to 155 Mph like they are in the U.S., with the BMW maximum speedometer advance allowance of up to 10% +2.4 Mph, the shutdown would occur as low as 135 Mph.

I believe that an FSC Code is needed to raise or remove the VMAX limit. It can't be coded.
