Idle RPM Cold Engine
Enter the RPM you wish to hold the engine when cold.
Max Temperature for Cold Idle Speed
The cold idle RPM is held up to this temperature.
Idle RPM Warm Engine
Enter the RPM you wish to hold the engine when warm.
Min Temperature For Warm Idle Speed
The warm idle RPM is held above this temperature.
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.
IAC Close minmap
When Map value is bigger the this threshold the Iac position will set to the Iac close position
Normally 510 (disable)
Usefull when Turbo preassure escapes on Iac valve
For testing: VemsTune can set fix position to IAC, see: Tools menu/IAC Lock
