The remaining fields allow you to program the Trim Control, Spare Input Function, Aux In
and Aux Out Functions. The Trim Control and Spare Input Function fields can be useful when
tuning the car initially as they can provide both a fuel and ignition trim that can be applied to
selected fuel/ignition maps for easy tuning:
Trim Control
The optional Trim unit can be used to control one of several parameters. This field
selects the controlled parameter. If there is nothing connected to the trim plug, the trim
will have no effect (except with boost control). The available functions are :
Fuel (Fine)
±12.5% adjustment of fuel.
Fuel (Coarse)
±50% adjustment of fuel.
Ignition
+7 to -8 degrees adjustment of ignition advance.
Ignition Trailing
+7 to -8° adjustment for Rotaries only
Boost Control
Boost trim for Wastegate control only.
Spare Input Function
The Spare input is an analogue input similar to the Trim Control input that can be
configured for one of several tasks. Its function is set by this field. The available
functions are :
General
0-5 volt input; no effect on ECU operation.
Fuel (Fine
±12.5% adjustment of fuel.
Fuel (Coarse
±50% adjustment of fuel.
Ignition Trim
+7 to -8 degrees adjustment of ignition advance.
Ign Trailing Trim

Baro Sensor
Barometric Pressure Sensor (internal/external).
Exhaust MAP Sensor

Aux RPM Limit

appears on the Engine Data Page as mV.
WARNING:
WHEN CONFIGURING YOUR SYSTEM TAKE CARE TO SET THE
SPARE INPUT FUNCTION CORRECTLY. IF THE SPARE INPUT
FUNCTION FIELD IS SET TO BARO. SENSOR EXTERNAL AND
THE BARO SENSOR IS DISCONNECTED THE ECU MAY PERFORM
INCORRECT BAROMETRIC CORRECTION. IF YOU ARE USING
AN EXTERNAL BARO. SENSOR AND REMOVE IT BE SURE TO
RECONFIGURE THE SPARE INPUT FUNCTION TO GENERAL.
