Auxiliary Outputs
The F9A possesses three output channels, each of which may be programmed to perform a
certain function. Each output channel is a pull-to-ground style signal suitable for switching
solenoids, relays or low-power dashboard lamps.
Each channel employs a 4.0A peak / 1A hold current driver. This is suitable for driving most
relays, solenoids, and other low power devices. Do not connect any device which requires
more than 1 amp continuous current directly to the ECU - it will not operate properly. If you
are switching high currents, use a suitable relay, either mechanical or solid state, and control
the operation of the relay with the ECU.
A number of function programmes exist within the F9A ECU. You may select any function to
be executed on any output channel, but no two channels may perform the same function.
Following is a list of available functions to choose from. This list will grow with further
development of the F9A system. You may choose any two functions from this list.
Turbo Waste Gate Control
Dual Intake Valve Control
Torque Converter Clutch Lockup
Electric Thermatic Fan Control
Electric Intercooler Fan Control
Shift Light Indicator
Auxiliary Fuel Pump Switch
Stall Saving Solenoid Control
Staging Signal
Turbo Timer
Note: - In some Advanced mode applications, one or two of the Auxiliary Outputs are not
available.
- Torque Converter Clutch Control cannot be used if a Home Trigger is being used in
Advanced Mode.
- Torque Converter Clutch Control and Turbo Timer can not be used together as they
use the same hardware. Choose only one of these. The Aux. In/Out Function in the
- Identification must be set for the correct function when using any one of these 3
functions.
