    i'm going to take a different approach to bus connection and lets see how that works but i'd like to know why yours fails on the bench and mine doesn't

    is it because it's a b-body bin and the idle traffic it sends out is quite different, or is it because my serial interface works differently than yours?

    can you run eehack's 'idle traffic scan' (in the debug section) on your bench setup?

    That's what i get for trying to flash WAY past my bedtime. Gibberish and noisy bus traffic, hah.

    Yeah I'll give it a whirl. This looks like a B-body BIN all right. I wonder what would happen if you put a B-body BIN on your setup. I think this has been discussed on here somewhere but how much BIN data outside of the XDF is unique to B, D, F, and Y?

    really they're the same

    one thing that's a difference is the comms code default bus master and module communications. the fbody and bbody bins use the ECM as bus master, and the ybody bins use the CCM as the bus master.

    they didnt change much else, the f-body datastream even spits out the y-body and b-body specific stuff, it's just not 'in the definition file'

    the fact that you did have issues and were able to re-flash again is definitely really good news, eehack would have bricked that thing for sure.

    you are totally right that i should just flash a bbody bin but i suspect your interface might be sketchy

    Quick update, in chronological order:
    1. flashhack refuses to read (although it read this PCM once last night).
    2. eehack reads just fine.
    3. flashhack writes just fine.

    I'll take further debug back-and-forth offline so I don't blow up this thread. Steveo, you have email.

    every log you sent me is full of errors and problems becoming the bus master so the read/write tests arent really relevant

    if it works at all its a fluke

    until it connects without errors nothing will work properly

    definitely an idle traffic log from eehack would be cool

    its in the raw command window i think

    i'm starting to think precise timing is the wrong approach. eehack had trouble here too. tunerpro is just awful at it. some interfaces have okay baud rates but their actual latency is awful. the current method works 100% on my particular laptop with my particular serial interface but that doesn't mean much. i have a drastic plan that will probably work. i will spend time on this and then need people to test it out...

    As always, more than willing to do anything I can go help. Looking forward to the new experiment!
