There are 4 user programmable auxiliary outputs. that can be used as either PWM or digital.
Digital outputs can be either ON or OFF depending on the programmable conditions. These outputs can be used to control relays that need to be turned on or off to control devices such as thermo fans or shift lights.
The pulse width modulated outputs (pwm) give a pulsing signal that varies the ratio of on and off time, this is referred to as duty. A signal that gives 75% on time and 25% off time is referred to as 75% duty. The ratio can be varied according to Load, RPM or TPS values via the user programmable table. This will give a varying average current to the device being controlled. Typically these outputs are used to control devices such as idle control valves and boost control valves.
Ticking the reverse acting box will cause the output to reverse its state. When the activation criterion is true then the output will be OFF. This is useful when activating relays that are normally closed. When the output is used as a PWM output then this will reveres the duty.

Auxiliary Output Modes
Digital Output modes 1, 2, 3, 4, 5, 6 All digital modes follow a set comparison sequence. If a comparison field is set to OFF then the system will skip to next comparison sequence.
