Greets all,
A few months ago I picked up a decent shape CPO 2020 M3P after dumping my F82-M4 when the pandemic first rolled in, and so far I've been pretty satisfied with the performance of the car, but being a maker and a data hoarder, I would love to access additional data from the car.
So far, I've gathered that the OBD-II port existed in some Teslas, but with that, there was virtually no usable data.
Next, I've seen many solutions out there using the CAN bus.
I took a drive to the local Tesla service facility and had a candid discussion with one of the service reps.
From what the rep said, tapping into the CAN bus is a surefire way of getting the warranty voided (as were suspension mods), or track-damaged cars.
One statement he said almost made it sound like interception of CAN bus data is logged in the vehicle (which wouldn't be out of realm of possibility, based on some experiences I've had with BMW). Has anyone else heard this?
Also, the service rep said there is a Bluetooth solution (for example) that can provide some of the data that folks dig out of CAN bus (speed, etc), but he couldn't find a link to what he mentioned in my brief time there. I've never heard of such a solution, and frankly can't imagine any bluetooth stack on the car allowing any cross pollution with CAN bus for a million reasons. I'm guessing he may have had a GPS-enabled solution in mind (and inadvertently said Bluetooth).
I asked him for clarification and I mentioned if he was thinking of a CAN-to-OBD-II-to-Bluetooth adapter, but he reiterated that he had seen a Bluetooth-only solution.
Has anyone here heard of a way to get any useful data out of the Tesla with Bluetooth? I think the phone-key approach uses Bluetooth LE, but again... I don't think there is an abundance of data coming back from the vehicle via BLE.
Some other options I'm rolling around in my head are:
-Roll the dice and just tap into CAN bus with assumption that if something happens, I can uninstall the CAN bus adapter just before bringing the car back in...
-Utilize the new Remain-Connected-to-Wifi feature of the software to force a connection to a hotspot on my phone and try to intercept telemetry data from the car as it goes through, but I'm guessing after TBONE they've probably locked things down
-Maybe try to do an RF read of CAN-high/low?
Any thoughts on this are appreciated.
