    Anyways, thanks for answers. I will check it all out!

    Customers are requested to submit their A50 read files to ensure their OS is mapped for our first parameter release.

    Where would you like the read files submitted? I have a 15878459 OS file that I wouldn't hate to be able to make changes to. Our only alternative right now is swapping in a A40 to make it perform the way it should.

    Do you want A46 files also? What is the difference between A46 and A50 for application purposes? It seems the A46 was very shortlived production run.

    A46? I have no idea if reading/flashing will even work with that TCM, it is not something we've testing in house anyway.
    I no longer monitor the forum, please either post your question or create a support ticket.

    From what I have gathered, the A46 was the replacement for the A40. When the A50 came out, they went to the A46 for the A40 if you need a replacement.

    Has anyone flashed one as an A40? It might work fine if there was no hardware changes.
