Tiida Problems

[bird want a ride]

Just bought a 2006 Tiida RO RO. Idling fast, was the problem?

sounds like the throttle body needs servicing

Put the car on the scanner & let the machine bring down the idle to 700 rpm & 6 degrees TDC.BTW there is a sticker on the underside of the hood.

eh heh?
and when he switches off what happens? the stock ECU retains values now?

Good question wagonrunner.

chemical, does that machine reflash / write new values to the ECU's rom? that's the only way those values would be permanent.

[Chemical]

It reflashes the ECU.

[wagonrunner]

It reflashes the ECU.

then why not disconnect battery for a couple minutes? or clear the self-learn?

adjusting operating parameters DOES NOT reflash the ECU.

[DSM_05]

It reflashes the ECU.

So therefore it replaces the entire ROM on the ECU?

Because you cannot flash "part" of the ROM's data. You'd have to reflash the entire thing - reuse the original mapping + the modified values.
