    Scanner MAF Reading 0.59g/sec in SD mode???

    Hi

    i am running a custom os and doing a mafless tune.

    I have disconnected the MAF with a mafless otr but in the scanner it is showing the MAF running 0.59g/secs.

    I though it should be 0 g/secs. Is this normal? Any procedure to reset?

    Don't log MAF, it's pointless if you failed it properly

    It should, but it does that sometimes. It doesn't matter.

    If you want to reset it, hook the MAF and enable it in the tune.
    Open ignition key and scan, don't start engine. It will read 0 HZ and 0 g/sec

    Close scanner and turn key off.

    On some cars with different pinouts they sense the MAF as being open circuit or dead and defaults to whatever resistance they have through the 5V reference. Sometimes they're zero, sometimes they're an obscene number. Nothing to worry about.
