I started this thread to put the hardware logging and graphical analysis stuff in one place. I will update the thread with drop box links to data as I collect it and welcome those that want to test and/or develop utilities to learn from collected data.
Special thanks to WK for providing CAN bus message decoding such that data loggers can be built.
I'll start with some data from a 0_60 using launch mode starting in the rain with traction events Here is a small excerpt showing just how much torque is loaded up against the brakes before launch

I took one of my OBDii tools (reflasher, data logger, scan tool, etc.) and repurposed it to do the Model S Chassis Bus CAN logging. The cable was purchased from FastTech and I simply added a DB-9 connector wired onto my board to connect +12V, Ground, CAN+ and CAN-. I'm not sure how I'm going to package this in a more robust way for others to use. I'll figure out something.
Only one of the 4 Mbyte flash parts is populated which normally turns out to be more than enough for logging data.
