    @Akikiki they really can’t just do mcu2 for everyone.
    probably 5ghz WiFi?

    Since it seems you have this information, can you disclose what is exactly the micron eMMC used in the new daughterboards? Is it a MTFC64GAPALNA-AIT?

    MTFC64GAPALBH-AAT is the one we seem to be seeing

    Probably nobody will see this comment since the thread is so long, but I just wanted to mention that I've discovered a really neat side-effect of the Tegra upgrade.

    BTW, I had the upgrade performed last year by @EV-Fixme and it went well. I removed the display and shipped him the defective board. A couple days later he had finished upgrading the memory, I then installed the upgraded board. To my surprise the removal and installation was easier than expected and I was able to fairly easily coax the top of the dashboard up enough to remove the display without having to take it off and without damaging the trim.

    OK, now back to the point: I often drive in mountainous areas with poor to no cell service, so I like to "preload" the map on the touchscreen by dragging it to where I plan to go before I lose service. However it used to be that I could only "preload" about 3 times the display area - any further and it would lose some tiles. Now, after the upgrade, I can drag the map around and preload in great detail over a dozen times the display area - and the tiles I've preloaded are retained for many days now. It seems that the additional size of the upgraded memory chip has a beneficial effect when using the navigation in spotty areas!

    Interesting, free space would not have changed. Lots of small map files sit on the eMMC, I wonder if you had bad ones in the past that possibly made your MCU think you had them cached already? I'll add your note to the front post.

    I would think that a new memory to replace a defective memory with lots of bad blocks would have more space available.

    It does have many more, however we kept the partition sizes same as Tesla, since we dont want to customize things just incase tesla decides to do something different in the future when all mcu1 have the larger eMMC. ;)

    A simple question. Tesla is proposing a remanufactured part for my MCU recall?

    why can’t I get a brand new part? Is that to much to ask?

    please advise.

    They don't make these parts any more. You get a new memory chip which is the part which wears out.

    Yes, it is too much to ask. Your warranty states Tesla can use new or remanufactured parts. Your car isn't new is it? Why would you get to demand a new part?

    And as @mspohr said, there likely aren't any new parts available, so it probably isn't even an option if you wanted to pay for it.

    So I’m clear.... I bought a brand new car with all new parts. One of the parts included a design flaw that caused a safety that was formally recalled. Regardless of if my 2017 P100D is new or not, it is under warranty. So what you are saying is I don’t deserve a new part but a used or remanufactured part?

    The way I look at it is, I bought a new car and while,under warranty if a part needs replacing, it’s should be a new part

    If new parts to fix my MCU1 are not available, why would that be my problem? Wouldn’t Tesla need to figure that out without providing me with used parts?

    The chip they are using the replace is new. The rest of the Tegra board is used. It's a pretty old board and likely not manufactured anymore.

    Again, why should I accept a used part for anything?
