Misfire detection by dluts-method (%DMDDLU, see )
This function allows the detection of random and continuous misfire, as well as non-symmetrical multiple misfire. Due to the 360° CS staggered value dlutsk the detection quality is independent of sensor wheel inaccuracies (crankshaft-synchronous segment time fluctuations). However, symmetrical multiple misfires (which also generate crankshaft-synchronous segment time fluctuations) cannot be detected, dlutsk is compared to a load and speed dependant threshold dlurs . Misfire is detected if the threshold is exceeded.
