    2Bar Map - Speed Density Tune Question

    By applying this tune ( I need a 2 bar tune now ) will the MAF still be refrenced or is this to be removed completly? I still see the table for MAF airflow listed.

    Thanks!!

    Just fail the maf at 0 hz like a 1 bat SD tune.

    It is still used if not failed in any '01+ OS, IIRC.

    So then I can run the 2bar tune and dial it all in, then enable the MAF and fine tune it?

    What? Why would you enable the MAF on a 2 bar tune?

    was just curious as to the application of it in a SD tune. THis is my first boosted car hence my first SD tune that will stay with the car. Ive only used SD to tune VE before so I am not as familiar with the tune.

    The SD tune is to use only the VE table. Otherwise it would have almost been pointless to spend the credits

    AH, the credits weren't an issue, spent those a while back on a 1bar maf enhanced...

    Im removing the maf completely from my system so I can run a larger inlet tube. Will just need to wire the IAT sensor in. Thanks for the info!!:thumbs:

    Yes, you will need to wire it in separate.
