Misfire detection by flute-method (%DMDLUA, see )

: fluts-method - %DMDLUA

The function allows the detection of continuous misfire at one or more cylinders. The filtered, cylinder-individual engine roughness values flutsk(cyl)  are compared to an accompanying threshold luar.  The threshold value is calculated from a load and engine speed dependent offset value, which is added to the lowest flutsk  value per working cycle.
