    Given the nature of software, I don't believe the OEM can prevent mishaps by locking down the software...

    the OEM does have ulterior motives (possibly influenced by by EPA/CARB requirements/mandates);

    locking out hotrodding/hacking efforts is of no consequence... if something is not right then the "software" won't work with the rest of the vehicle (due to both the complexity or the software, and the sanity-interlocks designed into it)... in fact the OEM's own software bugs will continue to be the OEM's worst enemy, not someone hacking the CAN/modules for the purpose running modified mechanical parts.

    Going to be a very debatable topic.

    come on now, they at least have a 5lt v8 and a couple of turbo 4 banger motors. I must admit they have knocked up the quality of sports cars in the last few years.

    313kw 5lt aint shabby.

    I know they are trying and are much better than the old Excel with nail polish paint colours, but high US $50K probably translates to nearly double over here, I doubt anyone will pay $100K for a Hyundai.
    They are a nice looking car though, I mistake them for an XF Jaguar when I see them.

    That sucks. Goodbye GM, I certainly won't buy another one.
    Now that beach side bar idea sounds good, pull up a stool, get a pitcher full with mugs and warm up the dart board.

    Or a standalone controller like Fast. We don't need no stinking CAN bus.

    Unfortunately if you want every other module in the car to work then you do need the ECM telling them what is going on. Like modern radios in cars, you are stuck with what they offer because the screen used for the radio also has climate control, sat nav etc, pull that out for something else and half the cars functions are gone.

    A friend had a piggyback controller on his diesel truck, he just unplugged the the PCM and plugged in the piggyback unit into the PCM, then the piggyback controller took over operations from the PCM. PCM never knew it wasn't controlling the truck, all other functions worked fine.

    They do that a lot with motorcycles too, you unplug the injectors and use a piggyback controller to adjust the pulse width modulation to obtain rich/lean mixture, ECU never knows.

    Don't forget about the reduced engine power that Gm implemented on the Z06 stingray to meet EPA. GM openly admitted that owners would have to use aftermarket programming to eliminate the reduce power!!
