Reset Base Idle

[Weyro]

Wondering if anyone can tell me how to reset the base idle using the idle screw, is it simply a case of turning the screw all the way back then resetting the ECU?

Cheers

EDIT: Which way do you turn it to turn idle down, cant check as the battery is disconnected

Start the engine and let it warm up to normal temp. Short circuit TE1 and E1 pins from the diagnostic plug and then turn the idle screw counter-clockwise to decrease idle RPMs.

to reset the ECU to base settings (albeit also everything else electronical in the car) you can just unplug the ground of the battery for like 5 minutes.

After that it will learn whatever small things you did to the engine in like 400-700km of driving.

Or remove the ECU fuse, so you don't have to set your clock/radio/player again.

Would be the better solution, you're right.

[Weyro]

cool thanks, which one is the ecu fuse?

[Weyro]

turns out its clockwise to lower lol

[JayJ]

Haha, was wondering if it was clockwise though. There should be layout inside the fuse cover, fuse should be small 10A or 15A

[Weyro]

Is it the engine bay fusebox or under the steering wheel? My engine bay one doesnt have a diagram

Or umplug the ecu behind the glove box

I would normally unplug the ECU to do this too!
