The help of the item "IAC Follows TPS When Not Idle" explains what happens when this option is disable:
"When the TPS is above the idle threshold, normally the IAC reverts back to the reference position selected from the IAC Reference Curve, PWM"
So when not idling, I understand one should have IACDutyCycle= IACRefPos which value is given by the Idle Refrence curve. However this is not the case as shown by the vemslog.
What/who is wrong?
