On a Golf 4 2.8L V6 AUE 022906023E 354077, the rev limiter has been set using KFTSRL (cut spark 6800rpm), FTOMN (0), all nmax maps 7100rpm, and dnmaxh 0. The rev limiter works perfectly from 2nd gear onwards but behaves incorrectly in neutral and 1st gear. If revved to the limiter in 1st gear, the engine speed limits to around 6200 rpm; releasing and then fully pressing the accelerator again allows it to reach the limiter and trigger the hardcut. The same issue occurs in neutral gear. This suggests there may be a restriction or offset that needs adjusting, but the specific parameter is elusive. A DAMOS file for the ECU is available for reference, so any insights or solutions would be greatly appreciated.
