E.3 Trigger Pull up
The default position for the Trigger Pull up setting is in the off state when being used with the
standard GM Ignition module. If the Pull up resistor is switched on with using this module,
the ECU will not be able to read RPM correctly.
If the Ignition module is changed to an aftermarket module, the Trigger Pull up resistor may
need to be switched on.
