KdFi Idle Control
The KdFi is stock equipped to run ON/OFF/PWM 2-3 wire idle valves.
Under ON/OFF the valve is on or off (open or closed).
Under PWM the curve is variable, this lets you adjust the amount of opening time as a function of temperature.
There are two ways these can be run:
- Open loop mode (also called warmup mode) simply tells the valve to open a set amount as a function of temperature. The simplest solution and most of the time sufficient for most engines.
- Closed Loop If the car is equiped with AC becomes interesting because in closed loop the ECU tries to maintain a set target rpm.
As a side note Hunting surging Idle is not necessary related to idle settings!
Engines like to idle a little richer to have a smooth idle.
Off-course the ignition, vacuum and mechanical condition of engine has to be near perfect to have a smooth idle

- 3-wire: +12V and FDLO or/and FDLC
