It should be included in BBNMAX: A 16. 20  Drehzahlbegrenzung function. That is one the most elusive functions in the M38x/M59x ECUs. The big problem is find a funktionsrahmen for it. DNMAXH should be inside the called speed limiter "vector or matrix" for those ECUs. NMAXZP  maybe could be similar to DNMAXH.

regards, i think you are correct. i do not see this nmaxzp (Speed hysteresis for speed limitation) defined in the several m38x and m59x ols files i have. i do, however, have  a .dam with this map defined. i have ordered the corresponding ecu so i can dump the firmware.

Maybe this spreadsheet can help you. I have done many time ago trying to understand the speed limiter function and locations. Of course the proper way should be disassemble firmware but that was a start point at that time.
