I am trying to implement a novelty sound device on the MX to simulate different sounds when the car accelerates. (yes..I will be able to turn it off because it will be very annoying)! I've tried 2 different devices that work on the MS reading the can3 high and can3 low data from the can bus port under the touchscreen. But it appears that (according to people on this forum much smarter than me) that Tesla might have slightly change the way the data is presented on the MX. So I am hoping someone has sniffed around and can give me some insight. I also tried a device that Canm8 that reads the tesla can data and converts it to a pulse output. It also won't see the MX signal. Thanks in advance.
