Tesla Model 3 Long Range 1st Production PUP EAP Deep Blue Metallic
Summary: updated Oct 2, 2019
This thread is our attempt to acquire and decode performance and other data from the serial networks in the Model 3.
We finally gained access, recorded data, and decoded a lot of powertrain CAN data in early 2019.
But there's still a lot more unknown! Additional help would be appreciated from any data and software folks.
Please follow along in the thread to see progress, or skip towards the end to jump into current discussions.
We also use this thread to detail our hardware and software projects to access, decipher, analyze, and display the data.
Below are some links to items in this thread:
Known CAN connector cables
OBDLink MX+ strongly suggested for iOS and Android connection to apps and loggers
ScanMyTesla app info:
Latest CAN log, from v10:
Some older logs that I made:
Dual acceleration and regen
Drive and Reverse
Cold batt charge
Charge and drive
Cold battery drive, AP, charge
My CANserver and microDisplay are now available to read and display all the fun can bus data!
My original dash display:
I'm hoping some of us nerds can figure out together how to access CAN data in the Model 3. I haven't found much information other than the existence of a diagnostic port hidden somewhere unknown. It also sounds like it will be ethernet with CAN embedded on another layer of data.
I'm hoping to figure all of this out and eventually make something that can grab useful data, maybe even output data to a geek display (dare I say HUD?). It should be possible. Now that my 3 is almost here I will finally have a patient to operate on.
Does anyone have any knowledge of this or come across other useful information that they can share?
