I just flashed my ecu and everything else seems fine exept the soft limiter is not working at all

changes i made:
10/16/2018 21:10:00  Scalar:    VNMX changed from 65.00 km/h (0x34) to 2.50 km/h (0x02).
10/16/2018 21:11:00  Scalar:    DNMAXH changed from 594.3 U/min (0x0949) to 50.0 U/min (0x00C8).
10/16/2018 21:11:32  Scalar:    ITNMXH changed from 50.380 s (0x13AE) to 0.000 s (0x0000).
10/16/2018 21:11:57  Scalar:    NMAX changed from 2350.0 RPM (0x24B8) to 3488.3 RPM (0x3681).
10/16/2018 21:13:44  Scalar:    TMOTNMX changed from 9.75 Grad C (0x4D) to -48.00 Grad C (0x00).
10/16/2018 21:14:33  Scalar:    TNMXH changed from 395.690 s (0x9A91) to 655.350 s (0xFFFF).

CWNMAXMD (CWDNMAX?) (8-bit) - Codeword Drehzahlbegrenzung (Codeword for RPM limiter). Change from 0 to 1

I dont have CWNMAXMD but I have CWDNMAX and its value is 88 so do i change it to 89.
the way i got 89 is 88 from hex to bin is 10001000 and if i change the 8th bit to 1 i get 10001001 which is 89 in hex.
I cannot find i list of those bits so not sure about the 8th bit :S
Or do i just change the 88 to 1, which would seem odd because it says from 0 to 1

What ECU?

For ME7.1, bit 0 is the only one used (CWDNMAX not CWDNMAXD)

If you are seeing other bits set, they may not mean what you think.

You'll need the FR for your ecu or disassemble to find out how to disable DNMAX

Might have found a problem with def files. I used ...._0001_public.xdf for making my changes and when i change to the other .xdf none of the right values are changed. Funny thing is that the car is running just fine :DD. Maybe ill make a new .bin by using the other .xdf and see if i get it to work...

Good day. If you want Launch contro is not it easier to use the program
Launch.exe? The program is on this forum. Launch.exe for 06A906032HN works well
