4. Event Update Rate sec The Event Update Rate sets how often the position of the idle motor will be updated When this time period elapses the PE3 compares the target idle speed to the actual idle speed and makes a decision about the idle motor position Setting this value too high will cause the idle speed to be slow to respond Setting this value too low may cause the idle speed to hunt and surge Change in Position Per Event This parameter sets the change in position in percent or steps that takes place every time the position of the idle motor is modified Setting this value too large will cause the engine to have large speed fluctuations at idle and a low value will cause a slow response Generally the user should start with a low value and slowly increase while evaluating performance Position Start This is the position of the idle motor in percent or steps when the engine has an RPM less than Starting RPM It controls the amount of air the engine receives while cranking the engine Position Start Time sec Position Start Time sets the amount of time that the PE3 holds the idle control motor at the Position Start after the engine starts and increases in speed above Starting RPM Position Park This setting defines the idle motor position in percent or steps when the TPS value is above Max TPS If the throttle position is greater than Max TPS the PE3 assumes that active idle speed control is
