4.2.3 Ignition Set-up Page
The Ignition set-up page contains the information about the ignition and trigger system the
ECU is to control. The Ignition Set-up Page is accessed via the set-up menu.
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. This setting also appears in
the Trigger Set-up page for convenience.
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
but this value can be in the range 0-25°BTDC to suit the timing marks that are
available on the timing pulley.
Spark Mode
This field defines the ignition delivery used, which for the E6GMX is fixed to
Distributor. (Please note that for the V6 GM vehicles fitted with the DFI module, the
module requires a Distributor type signal to operate.)
Output Type
This field defines the type of ignition signal with which the ECU will drive the igniter.
The options are:
Constant Duty This signal is used to drive intelligent igniter with internal dwell
control.
Constant Charge This signal is used to drive dumb igniters without internal dwell
control. This output type will not accurately control intelligent igniters.
WARNING:
THE CONSTANT DUTY OUTPUT TYPE SHOULD NOT BE USED TO
DRIVE DUMB IGNITERS SINCE SUCH IGNITERS DO NOT HAVE
DWELL CONTROL. DOING SO WILL RESULT IN TOTAL
FAILURE OF THE IGNITER.
Coil Charge Time (ms)
This field is only applicable when constant charge is selected. The value of this field
is a measure of time in milliseconds and can range from 0.1ms - 8.2ms. Typical values
are about 4-5ms.
Output Edge
This field defines which edge of the signal triggers the ignition event: falling or rising.
