Fig 1: Correction Programming Function (Engine 271)

Different performance maps for the engine control can be stored and activated with the correction programming in the ME control unit.

The correction programming can be carried out with STAR Diagnosis when ignition is "ON", via the data link connector.

The following maps can be influenced:

• Ignition maps for adapting to different fuel quality (except )
• Mixture maps for enriching the air/fuel mixture in different operating states (except )
• idle speed with transmission mode engaged (on transmission 722)
• Fault setting conditions for rendering smooth engine running (recognition less sensitive)
