Separate names with a comma.
You can ground pretty much anywhere on the chassis, use an existing ground stud in the area. You will likely not have the 12V connection, A...
Was your settings copied over, meaning if you still had your driver profile, homelink, etc? If so try doing some factory resets. One each day for...
current tempmon: tegra=66 board=54 Highest I noticed, tegra=76 board=63 lowest tegra=37 board=34 The mcu actually logs the temp, part of the...
thanks, but why not direct link the post? Preventive eMMC replacement on MCU1
A 85ºC chip should be fine, and what was used for 8 years. A 105ºC should be better. 85ºC = 185ºF I've recorded dash temps over 140ºC in other...
Correct, however the controller issue was mostly on one specific hynix chip part number, I dont have handy currently. We are expecting the Micron...
Does this mean my mind is in the gutter too much? [ATTACH]
Possibly OE. Also should be possible use modified OE parts without integration.
You can ask them for a MCU2, new MCU1 likely does not exist anymore.
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.
There are no new Tegras, reman from Tesla means they changed the eMMC chip, like we do. The last chip I saw from Tesla was that way.
You will need to run power or upgrade to a harness that has all the connections, and may need to upgrade the fuse box. Cooling should not be an...
Oh, thats a different kind of frozen, it sounds like your eMMC is on the way out. You may be experiencing many of the symptoms listed in the emmc...
If your eMMC is dead, you may loose all your save settings after replacement. If reboot works you would not likely loose your settings if your...
Sorry, no video, but this post shows the location of the MCU fuse, try pulling that. Also it sounds like your MCU is dead or dying due to eMMC...
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...
Hi Shawn, very close, actually F235 should be pulled, it's listed as center display in X diagrams instead of MCU. Not sure if anyone still needs...
Is that why I keep seeing adds about heated steering wheels and memory chips?
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...
You would want to upgrade to AP3 before you go mcu2, the AP config would likely be locked down in mcu2, mcu1 should be much easier, however many...
the mcu2 has a 5g modem now?
A year ago would be the 8 gig card.
I wish I could say that... Yesterday at the stop light I had a Y, 3, 3, 3, and X next to me....
Lets just say that the board was not made specifically for Tesla, and they were likely one of the smaller consumers for the boards ;) I don't...
Actually it looks like they just bought them, the daughter board does appear to be in other cars also. I would assume buying the rights to make...
Why not? We have 2012’s with 64 gig eMMC’s.
That is true. However owners who replaced before still should qualify for reimbursement for paying for the recalled issue before it was recalled.
Interesting. I didn’t get the email either. I need to go check my vins.
Tesla only replaces when the chip is pretty much dead. As the chip wears out, speed decreases dramatically. We have seen chips near EOL writing...
Old cars need tech package, however now I recently saw a post that non tech cars had something added to allow mcu2 retrofit. Have not seen the...
Not mine
You can also do a few factory resets, one day at a time. It takes a few tries to purge out all the corrupt old data.
The bulbs are great. I have them along with upgraded projectors.
There was a lot of demand from 3/Y owners. So we made it available for S/X owners.
You also need to add 2 pins to the yellow connector from SCCM to car, you can reuse one of the pins if you cut the lin wire, however you still...
Not sure about current software versions, with older car firmware enabling heated steering only required phone app to turn on and off the wheel....
My US 13 build turns on mirror heaters with rear defog before and after heated wheel. And no cold weather package from factory.
Please report final results, sorry the original post has gotten really long, I think I did specify doing multiple at some point. And I was hinting...
try 5-6. Note the fine print
You likely need some factory resets, and possibly an additional update. This often happens if some of the corrupted data gets copied to the new eMMC.
yeah, that too.
the heater ec The heater ecu plugs into the same plug as the horn, the 2 unused spots. You will likely need that harness also. You dont need...
This is a really weird one... Regen brakes will feed 60kwh into the system, most chademo send in 40-50kwh, however for much longer durations. I...
Can you post what version your on? We have noticed from time to time there seems to be some versions that cause crashes, however we didn't get...
Correct, good luck, Samppa can help you out.
generally the replacement should be 64 gig. Invoice should also show that. The daughter board they replace contains the eMMC memory chip that...
Completed. We did it along with facelift, not everything bolts in perfect, however everything fits and holds in place.
Currently only modem is available and SIM is restricted.
You can get a replacement motherboard, try posting and see if anyone who did screen replacements before kept their old board, You may be able to...
Screen replacements do not require programing. only circuit board replacements will require programing. Anyone removing their screen to be...
