Auxiliary Output Options
The Auxiliary output options page allows all spare ignition or injection outputs that are not used for ignition
or injection duties, to be configured for auxiliary devices such as tachometer output signals and turbo
wastegate solenoids. If the output is used by an ignition or fuel channel, then any auxiliary function
configured for that channel will be ignored.
In addition to the ignition and injection outputs, there are 4 dedicated PWM channels that can produce
PWM signals (pulsed width modulated wave forms) for BAC valves or switched style discrete outputs for
thermo fans and on/off type devices. Engine control outputs such as Ignition and Injection always take
precedence over auxiliary type outputs. All outputs are “pull to ground” style outputs which means when
the output is in the “on” state it is grounded. Each output driver is capable of sinking a maximum of
900mA, anything drawing more current than this will need to be coupled to the ECU via a relay.

PWM Output Types
PWM outputs are pulsed waveforms or varying duty and frequency. These are available on all channels,
each output is capable of driving a maximum of 800mA, if more output current is required to drive the
device connected to that output a relay is required.
All channels can be setup and disabled whilst keeping the setup information if required. In order to setup a
channel, you must first enable that channel. After selecting a function for the channel, you may need to
edit the parameters for the selected function. Edit these parameters by clicking on the Edit button. The
