    There is a lot of crud in them logs that you cant easily filter out. When decellerating during a log you should back your foot right off the pedal quickly so you can filter out the rich spikes that are caused. By letting your foot off slowly you can accumulate richer readings in your log file which will throw your BENS out.

    I agree with 5.7ute...

    The rest of the BEN's look good.

    Are you using then LC-1 to simulate HO2S11...?
    You might try to program the high voltage higher by 0.050V and the low voltage lower by 0.150V to bring it closer to HO2S21.

    LTFT has to be turned off in order to get BENs in line. Somebody correct me if I'm wrong!

    Why not just disable trims? {B3801} and {B4108}

    It will still go into semi-open loop mode (for stoich cells in B3647)... or at least mine seems to.
