    Default Holden Colorado MY14 Duramax 2.8

    Is there or going to be support for tuning the new MY14 duramax 2.8 diesel and the auto trans that behind it in the new Holden Colorado?

    Cannot get an ECM, not available through Holden spares yet so at this stage no idea.

    Well hopefully not too much longer because I would rather tune my own than have a chip

    No idea who even makes the ECM, might be Bosch, Continental, Siemens, might not even be possible to tune them via reflash.

    It would be nice to know it's actually possible. Because if not I'll have to look at some alternatives.

    I pick up my new MY14 Colorado hopefully at the end of this week.

    Would you like me to get any details off the ECU unit for you Ross, would that be any help to see if its viable?

    I've seen a picture of the ECM sticker but there was no brand on it, regardless there is a million things that can determine if it will be possible or not and without an ECM we can't even take the first steps.
    If does appear it is unique to the 2.8L engine, no other GM Diesel uses it.

    Sure, leave us the car for a month or so
    In all seriousness, having a look at the ECM's case still doesn't tell us much, it is what is going on inside that matters, I have some wreckers on the look out for us, someone will write one off sooner or later.
    When the Duramax LML ECM came out we all thought it was a Delphi because it had E38 style connectors on it....nope, it was Bosch inside.
