	ME7.5 Problem with hardcut « on: July 24, 2023, 06:50:41 AM »

Hello, I have a problem with HardCut not working, I have set FTOMN to 0, changed KFSZT, KFTSRL, NMAX, NMAXDVG, DNMAXH, NMAXDV.

But hardcut is not working, if I set KFSZT and KFSTSRL to 6600 RPM (also tried lower and bigger values), and NMAX to 7000, car goes over 6600 RPM to 7000 and does not hardcut. I tried DNMAXH to set 50, 100 and 200, the results are the same.

I don't know what I am missing more there as I have tried everything.

It is 1.8t - ECU nr. 4B0906018AA

I have added my changed file and mappack for that.

hardcut is fuel-injection related (Einspritzausblendung = injection turned off -> B_nmaxh)

hardcut -> nmot = NMAXOG + DNMAXH

NMAXOG = increased NMAX
DNMAXH = delta nmot for injection turned off (hysteresis)

usually you have:

NMAX = 6600
NMAXOG = 6600
DNMAXH = 200
