    Without saying too much we've made some great progress with Bosch ECM's over the last few weeks. Once we get our full flashing working for these ECM's we will probably be able to offer a 'reset ECM' option.

    Great to hear Ross, I hope you're ready for the 4.5L Duramax if/when GM decides to release it...

    I've only seen what they had at SEMA, beyond that I got no idea.

    Is there a place where this is discussed in more detail with regards to the LBZ? I was close to purcahsing EFI live or PPE and came across this while researching. I just want to be sure I understand this before jumping in.

    For LBZ GM have not enabled programming history logging, it's only LMM.

    Strange, the bulletin looked like it instructed GM to check the LBZ as well and walked them through the steps to do so.

    With my current TechII software (June 2008) when you try to read it on an LBZ the TechII errors and tells you that you have selected the wrong model. Who knows, maybe it's all changed again.

    Ross:

    I found this thread on Corvette Forum. I have an int erst in this situation as I now own a new Corvette. I also tend to put my faith in the folks here @ EFILive when it comes to my information.

    http://forums.corvetteforum.com/show....php?t=2065961

    I am no expert on this subject but it seems that some are advancing information that runs contrary to EFI's data regarding re flashing. The implication is that the competition to EFILive have the ability to alter factory tunes without affecting the CVN or that as long as the OS is not changed, no change is made to the CVN .
