It's actually KMB which is an abbreviation of KoMBi some German BMW speak for speedometer.
It's in the VN string of data of the ZCS coding which is the cars central coding key or Zentraler Codierungs Schlüssel.
Can anyone tell I've been playing with the coding on Chris's Mini?

P.S. someone at Omitec was told to remove BMW references from T4, but when it's reading the IPK, the DLL referenced at the top says KMB
