7.6 Idle actuators
This menu allows you to select the idle actuator used on the engine and the outputs that will control it. After this
quick setup, the idle speed parameters must be done according to chapter 20.2.
control idle speed by ignition timing
as configured in menus. If any kind of actuator is selected, the idle speed by
timing control is automatically enabled. This happens because the idle speed control was specially developed for this ECU,
integrating the timing control with the actuator reactions.
Electronic throttle
PWM valve
After selecting this option, it will be necessary to set up the output connected to the valve and the control
frequency. Small valves usually use up to 2000Hz. For big valves use around 80Hz. If your valve becomes noisy,
that the control frequency is lower than what the valve requires. In this case, increase the control frequency.
Be aware that the only outputs that can control these kinds of valves are the yellow ones.
Stepper motor
In this option, the four yellow outputs are used. It is necessary to inform which output controls which step motor
mode that allows the configuration of steps. As there are many variables in the manufacturing process, if
experiencing difficulties at number of steps. In some GM step
motors, 190 is the correct number. For some VW step motors, 210 works better.
After this quick setup, the idle speed parameters must be performed as shown in chapter 20.2.
