Replacing Maf's any specific procedure

I ordered 2 new mafs.

Is there any special procedure needed when replacing?
Do I need to disconnect battery or ecu or can I just leave the car off?

Does the ecu need to relearn should I clear the ecu with my durametric?

Thanks,

YJ

There are none that I know of. If you have the ability to reset the ECU/adaptations, that's not a bad idea to zero out fuel trims...but it'll sort those out quickly even if you don't.
