PID Idle Controller

Idle Controller, Other Settings

Important note:
IAC is very sensitive to VE settings,
wrong VE table settings can also cause rpm idle fluctations.
So before IAC PID tuning the VE must be set correctly!
To set VE in that range use Tools/IAC lock function.
RPM fluctation can be eliminated during VE tune with IAC lock function so it is easier to tune VE in this area.
