    Default Car Running Rich with Lean Plugs (Tune Inside)

    Like title says. Car runs great and pulls hard. Problem is the car smoke black and smells rich, but the spark plugs are white. Can anyone explain this? My car is in OLSD. I think its rich down low and lean up top, could that explain it? Which table should I make changes to? Ve, commanded AFR, PE, etc. Any suggestions welcomed.

    Hi Mikeyayell,

    What mods do you have...?
    Do you have any logs...?
    Did you filter out DFCO (or disable it) during AutoVE...?
    How close to 1.00 did your BEN map show...?

    What PIDS do I have to log for the BEN Map?

    AFR, wideband AFR, MAP, RPM.

    You file is all setup for AutoVE, did you tune that using a wideband...?

    See the AutoVE tutorial, it specifies the pids you need to log.

    Does the log look ok? How should I change my AFR?

    I can't tell... your log shows LC-1 voltages being flatlined, your LC-1 doesn't seem to be connected.

    Check your connections.
