    The idea of designing an ECM and having rock solid software running it is pretty daunting, these companies do an amazing job for sure so I don't want to rain on their parade in any way. But I'm not sure what benefit it would be to use one on the LB7 etc, maybe they do need to get serious about the L5P instead and with volume the price might come down.

    Now, i'm sure someone will think outside the box and (Even maybe simply) make it happen... but all of my techniques and contacts have been exhausted.. We will not be visiting L5P for at least a few months again... No clue what is going to be done!
    Let the Russians hack it, or have Snowden get someone in the NSA to hack GM's servers.............LOL

    But on a more serious note.........it will dampen new L5P sales and make the LML, LBZ market even stronger for resale values.

    GM Most likely will see these sitting on the lots, people who don't want to tune them will buy them, but the enthusiast with $60k+ and on top of that $10K in mods will refuse to upgrade.

    I know I had a new 2018 on my radar, but now a low mileage 2016 Denali is in my cross hairs.

    And yes, as Ross stated, a sad day indeed.

    I happen to know personally who is behind that project......I will probably have one for testing, he is a long time customer and personal friend.

    He has been working on it for a few years, the code will be void of any gotcha or "parameters" that look for or care about any thing other than the fuel system and turbos.............LOL

    No messages, dtc codes or gremlins, like LB7 code for an LML.

    I did not think he was that far along.

    I don't see how a race stand along will ever fill the position of of a ecm that controls many functions of other modues on the data bus.

    I thought the same thing, unless GM provided them with the intermodule CAN comms data it is probably for pure race trucks only. For the owner that just wants a bit better throttle response and better shifts with all emissions in place they will be out of luck still because I cannot imagine that ECM will have DPF & EGR, Urea control for the later models AND be EPA approved for road use.

    As far as I was told last year when it was mentioned to me it is a custom OS, the person writing the software is quite talented at many tasks, including encryption........the files and editor will be from what I was told very secure from hacking and reverse engineering.

    It would have to be their own ECM OS written from scratch or they'll find themselves in court if they reused any of GM's code. That is the impressive part for me, not sure how many people work there but companies like Bosch, Delphi etc have 'buildings' full of engineers to come up with what they do.

    If anyone is interested here is GM's patent on the new security used.
    http://patentimages.storage.googleapis.com/pdfs/US8930710.pdf

    No need to read over the whole thing because the paragraphs under "2. Discussion of the RelatedArt" explain the cryptography used. Notice also that it was filed in January 2015 and two years later it finally appears, I doubt there is any exploit in this, I think GM spent a long time getting it right.
