Tesla infotainment system upgradeable from MCU1 to MCU2
- Thread starter MurrayJimW

Yeah I have an average logging rate of ~2MB per day. Not sure what the number of writes those NAND chips are rated for though...

May I have this dance?
UH, No.
My thoughts are my own but most MS owners will trade regardless of what is in the MCU.
Just Human Nature
What matters are the new buyers not repeat buyers.
We can further this by offering to let friends try the car and you already know how that will turn out
You mean compressed ramdisk, but yeah. Should reduce the amount of writes drastically.

That’s great for FSD computer. But that won’t change MCU 1 to MCU 2 as that’s separate :-(
I’m hoping by next summer we have a clear answer of upgrading MCU 1 to 2. That’s when I plan on finally bringing in my car for the first time just before my warranty expires. Would like to get it at that time along with the FSD computer.
I don't think you'll have to wait that long. I think we'll have an answer sooner than that.

Oh really??I don't think you'll have to wait that long. I think we'll have an answer sooner than that.
Do tell...what little birdy has your ear?

Intuition says it will move to an SD card. Just because MCU2 retains an eMMC, doesn't mean that an upgrade for MCU1 would. Because of the IC display, an upgrade could not be simply a reharnassed MCU2. Not to make the eMMC change along with the CPU change would be folly.

I didn't know that video cameras existed when Winston Churchill was a baby.
Who says they aren't going to make replacing the IC part of the retrofit package?
They have to replace the IC if they retrofit. The IC on MCU2 is just monitor with an additional speaker. Where <= MCU1 is an actual computer.
Seeing as how I don't actually have to do the design work, I'd just put both ports on the MCU2.5; one for an MCU2 style 2nd display and one that's a network port for MCU1 style IC. To save money and ease integration I'd only put actual connectors on one or the other for factory assembly, but for repair parts I'd put both connectors on the board.
Yeah, it should be possible with the old IC if it they just have the right connection.
As an analogy, I can take an old computer (old IC) and turn it into a digital picture frame (new IC). I can't take a digital picture frame (new IC) and turn it into a stand-alone computer (old IC).
Does the MCU1 directly connect to the IC computer, or is it through that central network? If the latter, couldn’t this be handled in software, with a retrofitted MCU2 just sending the same data MCU1 sends?
It’s direct over 4 wire fakra. For the mcu1 it’s ethernet for mcu2 they use some 4 wire display port tech from intel.

It not a matter of being able to just physically plug a wire in. There is software/function changes. You talk about connectors like that all that matters is being able to plug it in.
