Idle Afterstart RPM, Added Value
Just after starting up, raise the idle RPM by this much, while afterstart active.
Idle Afterstart Duration
Lower the Afterstart RPM linearly down to target RPM after this many seconds.
TPS Value for Idle Threshold
Idle control (and Overrun Fuelcut) is active below this
TPS threshold.
IAC Follows TPS When Not Idle
When the TPS is above the idle threshold, normally the IAC
reverts back to the reference position selected from the
IAC Reference Curve, PWM. You can choose to let the IAC
valve follow the TPS for smoother transients in low load
driving.
For testing:
VemsTune can set fix position to IAC, see: Tools menu/IAC Lock
