    so far yes, sd is in full swing.

    All you need is for a MAF DTC to pop up immediately, does not matter how this is achieved.

    If the MAF tests never run, is the MAF disabled (does a MAF DTC show up...?), is this how this works...?

    If you do all of these:
    - swap C0301 and C0302,
    - set C0303 and C0305 to 1 (or 0 maybe),
    - set C0312 to 200 rpm,'

    does it throw a MAF DTC...?

    I have zero problems running the E92s in SD. I prefer to run in SD for our off road race apps. Just make sure the VVE is fully tuned and if there is cam movement, tune that portion of the VVE as well.

    I leave the MAF test operational and let it fault, never had an issue with it. I also disable the airflow correlation tests.
