    Should I drive during the log and if so how would you recommend I drive it for the log?

    Ok, I went and logged about 21 minutes of driving and some park running. Since my injury, I'm not able to read this the same and make adjustments and its frustrating me that I no longer know what I am looking at. At this point I am at the mercy of Joe and the group here to help me out before I spend the money to have this tuned by someone.

    Here is the log.

    Thanks for any help you guys can give me. I will be sure to add this tune to the new DropBox that someone is hosting here on the site.

    I'll look at your logs and I'll guide you along.

    I hope you're ok.

    The idea is this:
    - filter out throttle transients (which also eliminates VE),
    - make a ltft map to correct the MAF,
    - retest.

    We can then calculate VE from the MAF.

    I'm better but my memory and some knowledge is lost due to a head injury. Nothing like learning things you never wanted to forget and remembering the worthless shit.

    Ok, do this:
    1. look at table B5001, hightlight the whole table, go rightclick->copy-with-labels,
    2. goto scantool, goto a map letter tab, edit the map properties, on each of the Row and Col tabs click Paste Labels (do this in rapid succession, don't do anything else in between),
    3. on the Row tab select the MAFFREQ pid, on the Col tab select any pid,
    4. on the Data tab select the LONGFT1 pid (for now),

    see if you can get a LTFT map populated from your log.
