CHAPTER 10 OUTPUT OPTIONS SET-UP
The output options and PWM set-up pages are used to program settings for the output
functions of the ECU in a similar way as the set-up pages are programmed. Refer to 4.1
Using the ECU Set-up Pages, p27.

Closed Loop Control.
10.1.1 Idle Control
The idle control dialog is accessed by selecting Options->Idle Speed Control. The idle
control dialog has a series of fields common to the 4-wire bipolar stepper motor control and
BAC idle control.
There are ten parameters to be adjusted in the idle speed control:
Enable/Disable
The Idle Speed Control can be switched on or off.
Target Idle Speed
This is the engine speed that the ECU attempts to maintain at idle.
Cold Idle-Up RPM
This speed is added to the Target Speed when the engine temperature is cold.
Start RPM
For a period of around 20 seconds after the engine starts, you can specify an extra
increase in idle rpm. Most factory cars will rev 200-300rpm above the cold idle-up
RPM for a small time when they are first turned on. Setting the Start RPM to 0 will
mean that the engine will rev to the Target Idle Speed + Cold Idle-Up RPM when
turned on and resort back to the Target Idle Speed when warm. If you set the Start
RPM to 200RPM, then the engine will rev to the Target Idle Speed + Cold Idle-Up
RPM + 200RPM and resort back to the Target Idle Speed + Cold Idle-Up RPM after
20 seconds and then resort back to the Target Idle Speed when warm. Graphically, this
can be represented as:
0
Target Idle RPM
Target Idle RPM + Cold Idle-Up RPM
Target Idle RPM + Cold Idle-Up RPM + Start RPM
