@xAgyex a suggestion... I had a printed copy of instructions found on post #1 while dismantling my car. But I also found it very helpful to have a laptop in the garage with Tony's YouTube video. I would watch one step, pause the video and do the step, then proceed to the next step.
Good luck!

MCU with 32gb emmc

I think the key here is a new, faster EMMC (rather than size). I swapped mine out with Swissbit EM-26 32GB part, but kept the total partition sizes to the original 8GB (so Tesla software only has 8GB to use, the remaining 24GB I left TRIM'ed for the chip firmware to use for wear leveling), the UI is nice and fast.

Any body after to tell from that post if it was a non-Tesla 3rd party replacement of the eMMC or a Tesla replaced eMMC?

Anyone here looking for that MCU2 FM Radio custom made cable?

I am referring to the special cable that connects MCU2 and the digital tuner. My friend Teslatap.com documented the cable in his article about FM/XM Radio for the MCU2 Upgrade | TeslaTap. He made about 20 or so and stopped making them.

I found this site of someone that makes Tesla custom cables. He has them on his own site.

Check this out. EV Cables Company

Just an update here, my ranger and I got the car all put back together today with the upgraded emmc chip and doing the 4g LTE upgrade in the same shot.

Everything works flawlessly. I dont notice it being any faster but it has an update downloading for it now that my ranger pushed so will see more on the response part later. Interesting side note, from tesla diag side it shows null for all the values on the new emmc, it knows it is there but nothing about it.

Tesla put a new emmc for you?

The only work tesla did was removal and reinstall of mcu with the LTE 4g upgrade, I removed and reinstalled the daughter board with the emmc chip.

That is normal, Tesla's scripts pulls data from the 8 gig Hynix chip they use. The upgraded chips are not recognized by their scripts but dont have issues with operations from what we have seen.

Will that always be the case with future firmware updates?

 

[Akikiki]

What difference does that make as long as the car works fine?

Out of curiosity, do those same scripts also not recognize the very early Hynix chips, the ones which Tesla says they cannot tell the wear on?

Can anyone tell me how to get in touch with TonyT outside this Club site? I am having eMMC failure in my 2013 Model S - 95,000 miles.

 

[Akikiki]

TonyT is here every day. PM him a note or ask him to contact you. He will surprise you.

I am sorry to be so ignorant, but I do not know HOW to PM him. Is there a PM button I can't find on this site? It is very frustrating to keep having people say to "PM" him when you don't know how to do it.

How did you figure out how to make an account, post replies. But cant send a private message?

 

[UTArch]

The depth of my ignorance is not the issue. I am asking a simple question and berating my abilities is not helping. Please tell me how to send a PM.
