This thread is our attempt to acquire and decode performance and other data from the serial networks in the Model 3.
Things have progressed rapidly in the last few weeks as we finally gained access, recorded data, and are beginning to decode powertrain CAN data.
As it differs from Model S&X, a lot of work is needed to decode the massive amount of data. Additional help would be appreciated from any data and software folks!
Please follow along in the thread to see progress.
Some quick links:
And CAN trace captures that I have made so far:
Dual acceleration and regen
Drive and Reverse
Cold batt charge
Charge and drive
Cold battery drive, AP, charge
My dash display (work in progress):
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?
