TM-Spy (Unreleased) for Android

TM-Spy uses a standard ELM 327 type Bluetooth or WiFi OBDII adapter to decode information from the CAN service plug located below the center display screen. Check the internet for how to access this cable and the specifications for the custom adapter cable required to go from the Tesla 12 pin connector to the standard 16 pin OBDII connector which the ELM 327 adapter plugs into.
