    Answering if it's tune-related or wiring-related will require some actual data on both how it is wired and what the tune is. Without anything to look at I guess it could be... aliens? Who knows.

    Sensors (and wiring diagrams/pinouts) need to match the year/make/model of the tune file in the PCM, not the engine. All O2 sensors screw into the same kind of M18x1.5 threaded hole.

    Never 'upgrade' anything if you want it to keep working, that's my opinion. :mad:

    You need to forget about anything to do with 2006, as all the sensors and diagrams and pinouts will need to be for the 2001 Tahoe since that's what the PCM is going to expect to be there.

    Did the vehicle the PCM came from use flat case grounded O2s or square isolated ground O2s? Again (again), the year of the engine block and heads does. not. matter. for this part. You do not have a...

    Don't turn on DTCs for O2 sensors that do not exist. There are no B1/2S2s anymore, and there never were any Sensor 3s.

    Well that looks almost like the O2 signals are shorted to ground, and that's kinda unlikely so I'd suspect bad/junk sensors, or a mis-pinning problem on the PCM side of the O2 connectors.

    This...

    Need to see a log file.

    And you have a mess in your DTC settings, a whole shitload of codes for the upstream sensors have been turned off.

    Bank 2 is the passenger side, not downstream/post-cat.

    If by 'hard reset' you mean flashing it back to stock using a Tech2/MDI and SPS, then yes, that would do it. But if 'hard reset' means pulling battery cables then, lol, no.

    Lots of tables are in different formats/different axis labels between E40 & everything else and not the best choice to use as a reference for basically anything that came before or after it.

    Injector data does not look correct. Comparing to a stock '02 Express L31 file, the flow rate has been changed to 32lb but everything else is the same.
