    Figures. My Cruze gets rear ended and totaled then support comes out. lol. At least I have my mothers car to tune on. Looking forward to having support for these baby diesels.

    Rough. What did you replace it with if I may ask?

    For 'tuning' I'd say the cax has anything you would want. Certainly could be presented better, so I'm working on a bit of a face lift to make it easier to work with.

    The issue comes when you want to start tearing components out. Getting that to work is not easy. Mainly because these Bosch ECUs are masterful at making things look spaghetti.

    Agreed, I hate them.

    Maybe some of you may find these pictures interesting... Assuming my maths are correct.

    Next update (code named Memorial )is bringing names to the DTC type table.

    Could be useful, changing the type will work a bit differently than changing the activation table to 32768 (32768 effectively signs the short int so it becomes 1000000000000000, a negative number). In reality I think it'll be more just a quick reference. Should also mention that in reality they would be a crap ton of "X | Not Reported" (or a null type would maybe be more accurate). But because the Bosch DTC tables have a crap ton, I filtered all of the unused/reserved spots. I think the tables have somwhere around 900 elements each.

    Also added some tables used for said DTCs, like desired boost upper/lower error everyone is familiar with. They look kind of funky... Hopefully the scaling is correct.

    Other stuff as well. I added the MAF Sensor curve... Had that for awhile, but I'm not really sure how that thing is scaled, so I just did a bunch of logging and approximated. Should be pretty close though. Additionally there is support for the older OS. Turns out they are almost exactly identical so I'm told.

    Fun stuff!

    You deserve a medal for understanding the abomination that is Bosch DTC tables.

    Good news making the tables is done and over with. I had a script match all the indexes together, and make a cax for me.

    Also look what I found. It's the tables that calculate the timing for the post injections. Interestingly mode 0 is pretty much just not used (it's blank).

    Useful? Not really. But the whole point of me figuring this out was so I could figure out the post injection quantity tables. Which are useful.
