Function requirements for correction programming, general points

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

Correction programming is carried out with "ignition ON" using the Diagnosis Assistance System (DAS) over the data link connector (X11/4).

The ME-SFI control unit is connected to the data link connector over the chassis CAN (CAN E) and diagnostic CAN (CAN D).

The following performance maps can be influenced (programming):

Ignition maps for adaptation to different fuel grades (research octane number 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
