    Badlsx. Pull 10% out of your VE table in the 400 & 800 rpm row. 20% from 1200-3600 & 10% from 4000 up.
    This will get you a lot closer for starters.

    The tune you took that last log you posted with. It should put you within 5-10 percent in most areas.

    Always keep your first log. Its good to compare.

    I still do not understand how you got 15 degrees of KR at Idle. Lifter chatter? Did it make 'funny' sounds as it bogged and stalled?

    I agree with keeping all your logs. It is always good to look back & compare.
    It appears that the initial 14% increase that the AutoVE tutorial recommends was not necessary for your tune. That increase is what was causing the car to be way too rich. You may actually be better off by reducing the whole VE table by this amount instead of the changes I said earlier. This is because there may be too much difference between the cells that the pcm's interpolation will make dialling in too difficult.
    What I do is use cruise control to keep the data central in the rpm band. For example for the first section set cruise at 1200rpm, then 1600 rpm & so on. This prevents a cell that is too far out from having too much influence on the gathered data. It limits the map areas that you can get data for but you can then start working outwards from there.

    BadLSX,

    Are you logging using BBL or laptop...?

    Either way, get rid of the analog wideband pids AFR_LC1x and BEN_LC1x since they confuse the situation.

    With serial wideband connection, the pids are WO2AFR1, WO2LAM1, WO2EQR1, WO2ST1, CALC.BEN1.
