Figure 31: Ignition Setup Page
Set lock timing to ON and lock timing angle to 10 degrees. Crank engine, using a timing light connected to
ignition lead for number 1 cylinder adjust the tooth offset and trigger angle until timing reads 10 degrees
as viewed with a timing light on crank pulley. Tooth offset gives large changes to timing, trigger angle is
used to fine tune timing to exactly 10 degrees (any angle can be used as the lock timing angle. In this
example 10 degrees was used. It is however possible to set the lock timing to zero degrees (or any other
positive number) and adjust tooth offset and trigger angle until the crank pulley shows this value when
viewed with a timing light).
• Nissan Home Window - Nissan trigger requires the detection of a particular sized window to
establish the ‘Home’ position of the engine. Some Nissan triggers have several uniquely sized
windows that can be used for this purpose. This parameter selects which of the unique windows to
use. If this field is grey and not able to be changed, then ignore this parameter, as it does not apply
for the given trigger.
• Constant Charge Time - The time used to charge the ignition coils when Constant Charge mode
is selected. See Appendix D for more details on ignition systems.
• Spark Break Time - This is the minimum time between when the spark edge occurs and the next
charging edge is allowed to occur. This time will depend on how quickly the coil can discharge to
fire the spark. This threshold is only used when charging time is limited. This is only applicable in
Constant Charge Mode. The default value is 600
µ s.
