Trigger Mode

This field is only applicable if you are using an Internal Reluctor pickup as the
“Trigger Input”. The Trigger has two modes: constant mode and adaptive mode
adaptive mode uses software to filter out noise at low RPM when the reluctor signal is
weak. If you are having problems maintaining a clean trigger at low RPM the
adaptive mode may solve this problem. See also Trigger Gain in the Ignition Set-up.


Home Input

This field is only applicable in advanced mode if direct fire or sequential or batch
injection is required. This field has the same options as "Trigger Input".


Home Edge

This field is only applicable in advanced mode if direct fire or sequential or batch
injection is required. This field has the same options as "Trigger Edge".


Home Gain

This field is only applicable in advanced mode if direct fire or sequential or batch
injection is required. This field has the same options as "Trigger Gain".


Trigger Angle -

°°°°

BTDC

This field defines the angle in

°

BTDC at which the ECU will be triggered. The ECU

uses this value to calculate the time for the next ignition so it is important that this
value is correct since it will affect the base ignition timing.


Lock Timing

This field allows the Timing to be locked at a specified angle regardless of engine
speed. Select Yes or No to enable or disable Timing Lock.


Lock Timing Angle -

°°°°

BTDC

This field defines that angle in

°

BTDC at which the timing is locked. 10° is common.


Trigger Type

This field defines the trigger pattern the ECU will see coming from the crank or
camshaft angle sensors. The E6K currently supports the following trigger types:

Standard This trigger pattern sends one trigger for each spark event. For example a
V8 has 4 firing strokes for each crank revolution, for this engine the ECU would
expect to see 4 trigger events for each crank revolution or 8 events for each cam
revolution.
Multi-tooth This trigger pattern is the same as that for the Standard Trigger except that
there are multiple trigger events for each spark event. The number of teeth for a
multitooth trigger must be a multiple of the spark events. This trigger requires a home
signal for synchronisation of the trigger and engine position.

Motronic This trigger is a variation of the multitooth trigger pattern. This setting is
compatible with the BOSCH Motronic controlled engines. The Motronic wheel has
multiple teeth with a set number of teeth missing for synchronisation removing the
need for a separate home signal. The BOSCH Motronic wheel usually has 60 teeth
positions with 58 teeth and 2 missing teeth.

Subaru This trigger should be used when the standard Subaru trigger is used.

Twin Trigger This trigger is used in conjunction with twin distributor ignition
systems. Since it is s distributed system there is no requirement for a home signal so
this channel is used to carry the second trigger.
