Tesla infotainment system upgradeable from MCU1 to MCU2

[Alset4S]

Is there a route to upgrade the MCU or was Elon making a false promise?

Robby is correct

Has anyone experienced about a 1 sec lag. Its driving me nuts. Everything on steering wheel and screen has a bad lag. I did both resets and shutdown. Also navigation and trips. Dont know it's a mcu issue or normal. It's been doing this since February. I have a 17 MS 75

Ah. 13 pages for this thread just to get to the true question. You won't find the answer in all 13 pages. This remains one of the universe's greatest mysteries.

So, so true !

I’ve said it before, I don’t think it’s ever going to happen.

I have the AP2 + MCU1 combination... Past two weeks I`ve been having an odd set of problems that a two-screen reboot didn`t fix:

- GPS doesn`t work (always shows me at home, which is not great for long trips that require charging)
- FW updates fail (5 tries so far)
- Climate won`t stay on (says the battery is low, even when it`s at 80%+)
- Screen dimming doesn`t work automatically (need to set t manually)

And a series of small glitches. Does this look like an MCU problem to you?

What does your service center think?

MCU1 to MCU2 upgrades? They definitely will. Some evidence in the latest MCU1 firmwares that they’re getting ready for it. They added some tools in the firmware and on their servers to help migrate user data/settings/etc from MCU1 to MCU2.

Upgrading from MCU1 to MCU2 is doable, it just require swapping of IC and ECU unit. But it's not something that Tesla will do willingly. They still manufacture MCU1 units for replacements , at least as of end of last year.

Can you be more specific? Sounds interesting.....

Starting with fw 2019.12 they added a script to the MCU1 firmware called profile_xfer_utility.sh that can backup up your settings to Tesla's servers so that they can be restored onto an intel MCU2 unit.

Maybe that there so the profiles can be restored to a replacement MCU1 unit? What specifically about that script makes it clear that it's for upgrading to MCU2 and not just MCU1 backup/restore? Say, for instance, if you have an MCU1 or MCU2 as a loaner car, you can restore all your own settings for the duration your car is in service.

I would bet on that happening long before, and if, MCU2 upgrades become available.

True, but I hope @appleguru is right too!!!

# Intel UI profile data backup and restore utility

Script and API also reference "computer_replacement" so seems pretty darn clear to me what it is intended to be used for...

Also they already have a routine for MCU1 to MCU1 in toolbox, so this is definitely something new.

 

[HankLloydRight]

I remain skeptical we'll see an opt-in MCU1->MCU2 upgrade program. Too many other things to focus on to solve a problem that's not really a problem.

Also if it happens, we should be prepared for the possibility that it's only for newer cars. I can't picture them wanting to support AP1+MCU2 or Pre-AP+MCU2, for instance.

I'll admit that I don't know much in this area, but I don't think there's that much of a connection/dependency on the AP version and the MCU. I could be wrong, though.

But Elon said it will happen....

If they price it right (make some profit for the retrofit), there's no reason they can't support it on pre-AP and AP1 cars.

Yeah, especially if they time it to do FSD, yellowed screen and MCU all on the same visit. Seems like there would be a great profit opportunity, without much additional labor cost while the dash is opened up.

Agreed and fingers crossed as I have the yellow screen issue and would like my MCU changed too!!!!
