The tooth index that defines first ignition event. Detailed information
about the first trigger tooth and trigger angle configuration can be found

The angle defines the location of the First trigger tooth in relation to Top
Dead Center. This number will be a positive value that indicates the
number of degrees before Top Dead Center.
This value also defines the maximum allowable ignition advance. The
suggested value is between 50-60 degrees. Detailed information about
the first trigger tooth and trigger angle configuration can be found

When using trigger decoders with missing tooth (teeth) or an additional
tooth, during engine starting (Cranking) this parameter influences the
way the missing (or additional) tooth is detected. This option is useful
for engines with high compression ratios when the crankshaft angular
speed is uneven.
The distance in crank degrees from the last trigger edge, below which
any incoming trigger edge will be ignored as noise. This parameter is
used for noise reduction
This function activates the EMU scope function which allows logging of
signals on the Primary trigger, Secondary trigger and CAM#2 inputs
This option locks the ignition timing to a fixed value. This is useful for
checking the base ignition angle and trigger settings using a timing
light. Be sure to disable ignition lock after verifying timing.
