Aux. Out Function (Pin D5)
The Auxiliary Output on the E6GMX is set by default to Ign Bypass, due to the GM
Ignition module requiring this output. It can be configured for one of several
functions, but if you are running the factory ignition module it will need to be set to
Ignition Bypass.
The available functions are:
Disabled
No effect on ECU operation.
Ignition Bypass
Bypass signal compatible with some General Motors
ignition systems. This function allows the ignition system
to provide the spark at 10° BTDC at cranking speeds
(below 500rpm). This aids starting. The Aux Out Function
should output a ground signal (~0v) when the RPM is
below 500rpm, then switch to ~5v when engine rpm
exceeds 500rpm.
Staging Signal
Logic output that indicates Staging conditions. If Staging is
selected, and the Staged injectors are firing, this signal will
be high (5 volts), otherwise it will be low (~ 0 volts).
Tacho
Output
Used for driving tachometers when running a multicoil
ignition set-up. This output combines all of the multicoil
signals into one output and this is used to provide an RPM
measurement.
Ignition Toggle
This output is used for rotary set-ups where both the
primary and secondary trailing ignition signals are
connected on the single channel. This minimises the
amount of outputs needed to run this engine configuration.
Aux Out Voltage
Select either the 0 – 5v or the 0 –12v range depending on the desired output level
required.
Baro Input
Select either the internal barometric sensor or to use another external barometric
sensor.
INJ x Current
The ECU has two injector outputs: (INJ1) & (INJ2). These have the ability to drive
up to 8A peak and 2A hold current through the injector load. The current control
options must be set properly for the number and type of injectors connected. The
appropriate injector current control settings are further described in the appendix
WARNING:
THE CURRENT CONTROL MUST BE SET CORRECTLTY.
EXCESSIVE CURRENT PASSED THROUGH AN INJECTOR LOAD
FOR A LONG PERIOD OF TIME MAY DAMAGE THE INJECTORS
