    If it becomes common amongst tuners then we will follow too, but right now we don't know the impact of this 'bypass'. I'd rather not be the one poking the hornets nest right now thanks.

    Ross thanks for working hard on all of are needs with EFI, kicking the hornets nest is not what we need. Nice info on LLM and what we can all exspect down the road, I have a LBZ and hope your right on tracking LMMS only by GM.

    Oh and by waiting for others to test the water doesn't mean waiting to see how it's done. Spoofing CRC's is common enough, it's not exactly 1+1 maths, but it's possible to do.

    But I sat back and thought about what could result from allowing people to do it and really no good can come from it.

    If you have made a change to 'just' the speedo section to adjust for wheel sizes then you should be safe with GM as the ECM will only store that the Speedo segment was changed. It is that smart, it knows what segment was changed.

    I also understand in your situation bdr2008 that you would want it cleared.
    I don't want to shelve the idea of doing it, but so far the only thing I can see it doing is getting EFILive sued or GM making it 10 times harder to program these vehicles. Currently compared to other manufacturers GM have made it reasonably open for programming, they could turn that around very fast, especially using Bosch ECM's.
    Have a look what the Europeans have to do to program some of the Bosch ECM's -

    Yep, remove the bottom cover every time they want to program something as the OBD-II programming system the BMW's etc use is impossible to hack. GM could always go down that path too.

    We will be at SEMA this year so I am sure we will get a feel for what we should do from users and industry people...GM have a stand there right!

    So could a guy just reprogram 10 times with different tire size each time.......

    no I dont think so because that would only change the speedometer segment...? I might be totally wrong

    It does seem to be hit and miss when it logs a change (which is weird), if you changed the speedo segment 10 times then 'in theory' that should work, but I found that sometimes it didn't seem to log a change to other segments.
