Let the hacking begin... (Model S parts on the bench)

[Robert Fowler]

the gateway is crypto locked and ssh to cid /tegra no longer accepts password or local id_rsa ssh key logins after 2020.36.

Is it possible to view these keys based on the terrapin SSH vulnerability?

Hello guys, Is there any solution for Drive Units from Model S. I mean an immo off or virgin.

I'm selling off my MCU1 bench system. I created a custom wood mount and I'm selling it along with a batch of MCU connectors, power wiring, mini speakers, USB cable, etc. For more details:

Bench Mount for Tesla MCU1/MCU2 with Connectors, USB, Speakers, and Power wiring | eBay

This is a custom fabricated mount for any Tesla MCU from 2012 to 2021 (MCU1 and MCU2). The MCU is NOT included. Connection schematics for MCU are available for free from Tesla’s website. Two custom made 3D printer speaker mounts (left and right, attached to the speakers).

Let me know if you have questions. Here's what MCU1 looks like in my mount:

What, Instrument Cluster above it? Just kidding, nice mount! I build my setups for experiments like this out of acrylic. I reuse the bases from project to project, as they typically hide power supplies, fans, voltage and current meters showing readings out of their sides, and host things like network switches, USB CAN adapters, etc.

PS> To help avoid returns, you probably should do something like below in your listing picture, or if you have extra time, take two pictures one with and one without MCU from the very same angle, the superimpose the one with MCU on top of the frame only with some transparency, so it looks like a ghost of the MCU.

hoping this is the right place to ask… has anyone been able to unnerf or modify the 85kWh battery charging curve back to what it once was?

You would need to downgrade your firmware to mid 2019 or earlier.

Note: I have it on very good word that 85 charging speeds are limited by observed pack health (it's not just a kWh/session counter, serial number list, etc.), so if you go down this path, you are circumventing something that is trying to protect your battery.

Good idea. Image now modified!

Hey guys!

Can someone help me out of kindness to root my Tesla MX - MCU 1 please ?

For information, I have the firmware 2022.8.10.17 - Do I need to downgrade the software ? If so, how could I do it that ?

Thanks everyone for your help!

You could replace your Tegra board with eBay 256166977500 2020.36.16 board. You would however need to have your SSL keys extracted off the current eMMC in order to maintain communication with Tesla aka App access.

Hi, I can't find clearly this information, does the battery pack isolation value is published on CAN3 powertrain (on a TMS70D 2015). If yes on which ID is it ?
Thanks

its def there in 2 places judging by Diag mode, but idk how to figure out ID, maybe i can grab CAN frames n find ones that match my value... project for later lol

The tesla_models_awd file seems to be coherent with a 2015 version id but isolation it not defined in this file.
Isolation seems to be defined in tesla_models.dbc file but this definition seems to be for a more recent car version ?
I'm surprised this information is not well known and identified in tesla community can database... nobody used it in a third app or similar ?

 

[brainhouston]

yeah i've noticed that
not sure why theres whole bunch for model 3 n nothing for legacy S/X
also, SMT doesn't have isolation so idk if its hard to decode or nobody cares...

 

[piwhy]

It means that the only way to get pack isolation value on a non-rooted mcu legacy TMS is to pay a toolbox session ?

Hello.
Have a big problem, build my us spec 2013 gen1 obc to eu dual gen 2 obc.

Problem is it fail instalation software. Have try several times whitout success.

Any ide what to do?

My alerts,those 2 on top came after last installation try..

 

[brainhouston]

i would think that maybe gateway change needed?
single to dual charger or US to EU change..
not sure why BMS errors showed up but i believe update might not work with some errors..
