Welcome to the MSS54-XDFs wiki! Here we hope to compile a list of most common items to adjust.

Idle Speed Adjustment

Aux Fan Speeds

Idle Speed Adjustment

1. NSOLL_AC (RPM) (Target Warm Idle)
2. NSOLL_START (degC, RPM) (Start Idle Map)
3. NSOLL_GRUND (degC, RPM) (Warm Idle Map)

Aux Fan Speeds:

1. K_ELU_TKA (degC, Fan Speed)
2. K_ELU_V (Vehicle Speed, Fan Speed Ratio * K_ELU_TKA)
3. K_ELU_KKOS_ERSATZ (Fan speed when there is no IHKA communication)
4. K_ELU_KKOS_Xof16 (Fan Speed based on AC Load)

When removing AC, zero the values in K_ELU_KKOS_ERSATZ and E_ELU_KKOS_Xof16), so that fan does not run at the 60% default.
