Function requirements for correction programming, general points
- Circuit 15 ON (ignition ON)
- Circuit 87M ON (engine control ON)
Correction programming, general points
Different performance maps for the engine control can be stored and activated with correction programming in the ME-SFI [ME] control unit (N3/10).
Correction programming function sequence
The correction programming is carried out with "ignition ON" over the data link connector (X11/4) using the Diagnosis Assistance System (DAS).
The ME-SFI control unit is linked to the data link connector over the engine compartment CAN (CAN C) and diagnostic CAN (CAN D).
The following performance maps can be influenced (programming):
- Ignition maps for adaptation to different fuel grades (r esearch o ctane n umber correction) (except code (494) USA version)
- Mixture maps for enrichment of the fuel/air mixture in different operating conditions (except code (494) USA version)
- Basic setting for idle speed
- Idle speed for engaged drive position
- Fault setting conditions for smooth running detection
- Temperature correction for switching the engine and air conditioning electric suction fan with integrated control (M4/7) on and off
