Edge selection for multitooth trigger wheel signal
When a trigger wheel with equal tooth spacing ( multitooth ) is connected to the Primary Trigger
input, and synchronization is based on a camshaft trigger wheel signal, edges should be selected
in a manner that gives the maximum distance between Primary Trigger and Secondary Trigger
edges. If the distance is too small, the synchronizing trigger tooth can change at higher RPM.
Incorrect trigger edge setup for multitooth
Correct edge setup for multitooth
Proper edge selection can be checked by monitoring Cam sync trigger tooth parameter in log. With
a multitooth trigger, this parameter must be constant. Any Cam sync trigger tooth change during
engine operation indicates incorrect edge selection or poor trigger wheel signal quality.
