Correction programming, general points
Different performance maps for the engine control can be stored and activated with the correction programming in the ME-SFI [ME] control unit.

Correction programming function sequence
Correction programming is carried out with "ignition ON" over the data link connector using the Diagnosis Assistance System (DAS). The ME-SFI [ME] control unit is connected to the data link connector via the drive train CAN and diagnostic CAN.

The following performance maps can be influenced (programming):
- Ignition map to adapt to different fuel grades (without code (ZU8) USA version)
- Mixture maps for enrichment of the fuel/air mixture in different operating conditions (except code (ZU8) USA version)
- Basic setting for idle speed
- Idle speed for engaged gear range
- 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
