ECU does not control the idle RPM.
Its the IACV that controls ur idle RPM.
Want to tune it, change the IACV.

>>> hmmm... somewhat I do agree with you. The idling screw is the mechanical component that controls idling speed. So if I set it to idle at 1000rpm, the ecu will tell the IAC to allow more air in so that rpm reads at 1000rpm.
Why I said somewhat is becos the idling screw does play a part in idling as oppose to saying that the ecu have final say.

As we all know, when your car is on neutral (idle).. it consumes a certain amount of petrol to keep the engine running... I heard someone telling me that when you are cruising on the highway... if you keep on gear and let the car cruise downslope without stepping on petrol...then the car is not consuming any petrol..as the momentum is "running" the engine.. is it true?
On the other hand, if you put to neutral and let it coast (think it's called freewheeling or something)..then the car consumes the same amount of petrol as it is when idling...
Any experts to comment this?
I'm driving the Lancer GLX sports 2004 model.
