    I tried it and I was able to select all the calc pids ok (no red X thru any of them).

    Me too! And got correct looking data in MAPS... Gone a little blind here with the issues and learning so I'm hoping somone can give it a shot with fresh eyes on a rig.

    If you have any luck with some new paremeters I think I found some:
    Commanded AFR x 2560
    Dynamic cylinder airmass
    Dynamic airflow, val = g/sec x 81.92
    SD grams/cyl airmass x 8192
    MAF derived cylinder airmass x 8192
    Mass airflow rate, g/sec = val/81.92
    #1, P0101: MAF sensor
    #2, P0102: MAF sensor
    O2 Switch Point
    Rear O2 sensor mv limits, to stop feedback

    Closed Loop Enable temp
    or
    Min/Max INT and BLM either way WB tuning would work without disconnecting O2 sensors.

    So the good stuff is there!

    Any word back on adding whats needed? Or fixing SAE.AFR? Just seems wrong to use one marked SAE.AFR_B LS2...

    Missing and can't find :B0120: Change RPM Threshold for Airflow Calculation from 4000 to 400
    Eliminates any Airflow Correction from the VE Table

    B1147 MPH description says engine speed.
    Lots of stuff is there, way more then this list.

    ;Commanded AFR x 2560

    ;Dynamic cylinder airmass

    ;Dynamic airflow, val = g/sec x 81.92

    ;SD grams/cyl airmass x 8192

    ;MAF derived cylinder airmass x 8192

    :Mass airflow rate, g/sec = val/81.92

    ;#1, P0101: MAF sensor
    ;#2, P0102: MAF sensor

    ;Short term fuel trim min and max
    ;Long term fuel trim min and max
    ;O2 Swing points
    ;Loads of O2 sensor paremeters.

    That list is not all inclusive and some may not be needed to completly use all the tuning tutorials..

    I know this was a while ago, but I'm gonna see if this works for my L29 over the holidays. Seems like it's been forever since I played with the truck, mostly just been working it hard. Towing a big 5th wheel around and I need all I can get out of it (safely of course).
    So it'll be a bit, but I'll let you know how things work out.

    Will be interested to hear how this works. Its hard for me to tell if the calc pids was finalized in the thread?

    Make sure you understand the principles of the procedure...

    you may need to improvise if a pid or two are not supported.
