    Default calc.vet pids and setup

    can i have a few pairs of eyes look at what i've got setup for pids and calc.vet tune setup, in the first log i've done, something seems off, and i'm obviously not smart enough to figure this out...
    I have a serial wideband aem 30-4100 on it and i feel like maybe the pids are not set up right for what i have?

    info on vehicle is 05 yukon 5.3l 4l60e 4wd lowered 285-40/22 tire
    5.3l lm7 with following mods...
    gm asa grind cam .525 int/exh lift, 285exh/274int duration, 236exh/226int @.050, 106 intake centerline, 110lsa, howards part#197715-10.
    1-3/4" longtube headers, no cats, single 3" flowmaster out the back exhaust
    4l60e has a torque convertor from a i6 trailblazer, stalling at roughly 2200ish

    Your log file shows that the pid EXT.WO2LAM1 has invalid data... i.e. lambda data is not being read correctly from wideband...

    how did you configure FSV2 for wideband...?

    I'll have to double check my device settings, I just read through the device setup sticky again, and i don't recall a couple of the steps, will check and report back tonight,

    thanks

    double checked my device setup, everything okay there, i'll have to double check my wiring setup for the serial coms input though, but i'm sure i triple checked that when i installed, is it maybe in the text file i wonder?

    You log shows that you have current DTC's P0101 (failed MAF) and P0106 (MAP performance)...

    are you intending to run VE-only (i.e. failed MAF)...?

    you will have to fix P0106 (if MAP sensor checks out ok, then look at MAP sanity table in Engine Diagnostics section of the tune).

    Try setting C5501 to 0 rpm.

    I don't intend to run on VE only, i've made some adjustments in the tune file from the summary notes in the calc.vet sticky, to help with tuning, but otherwise i feel like the dtc's are stemming from the camshaft that i have in this thing, it has lots of overlap, not radical by anymeans but it has a pretty healthy chop to it.
    i don't believe the maf or the map are faulty.

    can i ask what the purpose of setting c5501 to 0 rpm is for? will that allow me to continue with the tuning of the calc.vet?

    If the MAP sensor checks out ok, then setting C5501 to zero avoids running the test for P0106... we want to avoid having this DTC trigger because its presence may affect what the PCM does (with other tables/modes).
