    If you want DFCO to activate, set these back to stock.


    4. B4105: O2 Switch-points to 450 Millivolts

    Leave this as is at 450 mV.


    5. B3618: PE Modifier Based on Rpm (EQ): 1.16
    Safe adequate Fueling regardless of Fuel Type
    Leave this as is (any value in the range EQR 1.160 to 1.175 is ok).


    6. B3616: PE Enable: make sure PE enables as load becomes significant
    (e.g. below 60% TP below 3200 rpm, 35% TP above 3200 rpm).
    Leave as is (you want PE to be readily available).


    7. B3608 and B3609: PE Delay: set these to zeros.
    Leave as is.

    applied from the VE Table B0101. The amount of airflow correction and its effects on
    LTFTs is complex. Most beginning users can leave the RPM Threshold at 4000 RPMs.
    Your LTFTs will update over time, so it is always best to perform additional Quality Control
    runs periodically.
    Set back to stock when finished tuning.


    2. Parameters {B3308} and {B3313} for Disabling DFCO:
    Set temperature to 140
    Set back to stock when finished tuning.

    Perfect!
    Just what I needed.
    My widebands will hopefully arrive this week so I can give this a shot next weekend.
    Thanks again Joe!

    Well, as my luck would have it, my new WBO2s arrived on Friday and now the weather is too crappy to take the car out to get some logs (I won't take it out with salt on the roads). So it appears I'm in a holding pattern for a while.
    I did have a question on hooking up 2 WBO2s with Calc.Vet- Is it possible?
    Since it appears that I do have some differences (nothing too major) between the banks when looking at my fuel trims, does it make sense (or is it even possible) to look at both bank's WBO2s while running Calc.Vet?
    Just curious.
    Happy Holidays!

    Yes, we can edit the calc_pids.txt file to use 2 widebands...

    I dynamically select the leanest wideband (i.e. I have a calc pid that selects the leanest lambda on-the-fly)...

    we can edit this into your calc_pids.txt file...

    connect your two 14POINT7 wideband to FSV2's AD1 and AD2.

    That would be outstanding!
    I will be building my WB logging wiring harness over the holidays so I can incorporate both WBO2s into the design.
    Thank you again Joe!
    I don't know where I would be without your advice and expertise.

    I modified your calc_pids.txt (from post #46 above), see attached.

    Wow, that was FAST!
    This is excellent Joe, thank you SO much for doing this for me.
    I'll keep you posted when I can finally get some logging done.
