    Default AutoVE on our PCMs?

    I've been trying to figure out
    1. how to do Auto VE tuning
    2. if my PCM is even capable of this.

    Trying to read through the tutorials, not having much luck. Anyone know the answers? Thanks!

    btw, I have V2 but do not have a WBO2.

    You should be able to do it, will have to build your own map in the scan tool. Need to make sure the black box PCM can output commanded AFR or EQ Ratio to make the map.

    I did it 2 years ago, You do need a Wideband and you need to disconnect both front O2 sensor's to put pcm in OL...

    I don't work with the "Black Box Vortec" PCM ... but I agree with Erik - it should be possible.

    You will need a WBO though ...

    Your Main VE table (B0101) will only display in g*K/kPa (not percent) ... you will need to get use to this. You also have a Backup VE Table (B0103) - like early LS1-B PCM OS.

    Your MAF table (B6345) is in Hz vs g/sec ... so no issues there.

    Read the AutoVE Tutorial (AutoMAF implied) ... you should be able to apply these techniques.

    Thanks guys! WBO2 is not in the budget for a while, but I'll be reading up on these so I'm ready when I can get them.

    The Calc.VET/Calc.MAFT tutorials may help...

    without a wideband those tutorials allow you to calculate/correct a portion of the MAF/VE tables using LTFT's (i.e. in Closed Loop); you will need properly functioning NBO2's;


    to do the rest of the VE/MAF tables you will need a wideband.

    Thanks Joe. Maybe I'm not reading the correct tutorial. Can you post a link?

    I did it 2 years ago as well with my blackbox. Just read the tutorial and went to town. After 2 datalogs the thing was dead nuts on all the cells I could hit.
