Before shutdown it was running on Combustion Feedback Mode. Now it is running on "Pre-Chamber Calibration Mode". Engine should run in "Combustion Feedback Mode" with above mentioned parameters. Does someone has any clue for this mode problem.

 

Can you brief engine loading procedure? prechamber calibration mode is either manually activated or it becomes active if engine is not stable under idle condition (no load)
