Since you now have an "in" it would be awesome if you could gently hint that read-only diagnostic access would essentially halt all desire to break-in to the software. I honestly can't imagine that there are blackhat hackers out there wanting to root the CID of the Model S. They've got much bigger targets in mind. I really think diagnostic access is a win-win.
I did talk briefly about a "geek mode." Seems there are, rightfully, things with higher priority.
Yeah, that widget on the IC is kinda cool. What data actually populates battery temp? I thought the battery had a total of like 16 sensors, so do they all get averaged when reported as pack temp or is one randomly selected?
I think the "Battery" one is an average of all of the sensors, and the "Batt Outlet" one is the sensor at the end of the cooling loop. Brick min and max are the lowest and highest individual cell group voltages from the whole pack. BMS is the full pack voltage. All of this gets populated when I play CAN recordings to the power train CAN of my bench setup.
I would really like to see cooling information as well as cooling fan speed and real-time kW usage from pack heater.
Me too. Lots of data here.
And here is the part where some people will get angry at me for some reason... (maybe because I'm using too much bandwidth?
)

All shots taken with the screenshot save program the car uses when sending bug reports and such... and a few of them somewhat sanitized to scrub potentially identifying info, obviously, and added my little watermark.
The DOCS tab isn't interesting... just has some images of a few of the manual pages describing the under-hood fuses... nothing important. The APPS tab you see in my earlier photo.
The cool thing is, when I play back CAN data this info is updated in near real-time. This is how everything looks with just the CID and IC connected. I didn't get a shot of the BMS screen since it doesn't work until I play some CAN data and I didn't have that set back up yet.
The CAN tab is awesome. I mean, pretty much EVERYTHING the car does can be monitored from there. There are hundreds... perhaps thousands of variables that can be shown.
There is nothing really secret in these screenshots, so I really don't see any harm in posting them. Enjoy.
