    Default Since GM tuning is ending...

    Maybe touch back on these old P01 and P59 PCM COS's?

    Boost control in place of EGR logic with boost vs gear
    Launch control
    Closed loop wideband control

    I know this sounds very far fetched and I'm no coding expert but if they can do all these things with a 32kb Honda ECU from the 90's surely these fancy controllers with tons of I/O can handle it!

    Well the P01 is going to be 20 years old this year, so whoever was interested in LS1 tuning probably already owns a product (with unlimited licenses) to do so.
    I personally last worked on the LS1 PCM in 2006 as far as code modifications goes, I think I might have forgotten it all by now
    Anyway, there is pretty much no chance EFILive would revisit and enhance the LS1 offering, I know shops still tune them daily and make good money from LS1 tuning but the is no business case for EFILive to invest the R&D time in to LS1 now.
    Need official EFILive help, please go here.

    Very understandable sir. With coding I'm sure you could implement a pay to use scenario to justify the R&D but just wishful thinking mostly.

    I wonder what's next. Remember when OBDI came out and everyone thought the sky was falling?

    Well the thing to keep in mind is GM's security on the new ECM's isn't anything they necessarily cooked up from scratch, it uses proven security methods that have never been compromised.
    The only security compromise is likely to come from within GM's own security division, but I also highly doubt that will happen any time soon and even if it did what tuning company would be stupid enough to want a piece of that illegal action?
    Sorry but with this new security you can't make comparisons to when old tech came out, it's all very different.

    What measures are they using? Even sha256 can be compromised using rainbow tables. Security measures are often circumvented rather than broken. Don't forget that physical access is a huge advantage even though gm is counting on everyone having it. There would be a ton to learn using something like wireshark while a dealer "unbricks" or updates your new vette. Why not put a bounty on it? What's continuing support for new vehicles worth to you. Fly a couple efi live reps to vegas for defcon. If you don't do it somebody will.

    What I was alluding to was, if hacking new PCMs really does become cost ineffective, what's the next alternative in line? Will the standalone market explode? Will the internal combustion engine suddenly become defunct?

    I think a great comparison to this is the video gaming console market, remember how rampant piracy was with the early Playstations and Xbox's? As each new generation console got released the security stepped up, at some point all the open doors get closed and you have to accept defeat and that technology won the war. There is no 'mod chip' for the Xbox-One or PS4, they've been out for 6 years and still nobody can get around the security to play pirated games which was the whole intention of any security those companies engineered. I would suggest the best digital signature cracking minds would be working on those non stop rather than cars.
    Actually there probably is a few people able to execute exploits on these consoles but it's not something to mass market or maybe they are concerned about SONY's reaction (and why shouldn't we be as concerned about GM?)

    Again they will be shut out by technology, GM has encrypted CAN bus in 2020. Lets assume there was an ECM that could run the engine, nothing else on the car will work.
