    This, exactly.
    Even if you get lucky and tune for E50 (the minimum), that just means you need another tune for E83, then maybe another tune for E72, and another for E61 ...

    If govt emissions agencies mandated OEs to put post-cat O2 sensor at the furthest end of the car's butthole, they'd do it.

    Never had a dyno tune myself, witnessed several. True, most dynos use a tailpipe sensor.
    Always thought tailpipe sensors detect / analyze differently than wideband O2 sensors?

    A wideband O2 sensor after the catalytic converter is analyzing how well the converter alters engine exhaust.
    The entire point of a wideband O2 sensor is to analyze UNALTERED engine exhaust.

    I've personally witnessed TunerCAT OBD2 brick 10x more OBD2 LT1 pcms in Windows 7 than TunerCAT OBD1 in Windows 7.

    Were I in your place, first thing I'd do is let TunerCAT know about it, in as much detail as possible.
    He deserves a chance to learn from, and do something about this.

    Reminds me of my ol '94 Caprice wagon, came with 2.56.
    Without a downhill or a tailwind, 4th gear was utterly USELESS. That wagon spent so much more time in 1st or 2nd or 3rd than in 4th.

    In that...

    Purv-Dawg,
    I daily drive an '02 Tahoe Z71 - L59, 4L60E, 3.73, 265/65R18 (31.56" tall) - all over NY, NJ, CT (and occasionally PA RI & MA).

    So far as I know, a pcm cannot be bricked by reading it.
    If JET DST somehow bricked it, it was during a previous write.

    Yes.
    If you want to communicate with the OBD1 pcm, you want an OBD1 cable, even if that OBD1 cable has an OBD2 adapter on one end of it.
    If you get the 'Y', this becomes moot.
