signal amplitude to drive the ECU. When choosing the Trigger Gain start at
‘0’ and increase the gain until a steady trigger signal is seen, this can be done
when the timing is checked for the first time. During cranking check that there
is ignition and that the timing mark on the pulley wheel does not jump
erratically, if there is no ignition or the timing mark jumps erratically increase
the gain until the timing mark is steady. This should only be done when the
installation is complete.
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 ignition 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 ignition or sequential or
batch injection is required. This field has the same options as "Trigger Edge".
E6M and E6M-8 ONLY
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 E6H/E6M 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
