I don't have it (yet, at least), but I'm pretty sure it doesn't. However, I've been working on deciphering the 'background' OBD2 codes (the ones that are sent by the car without being requested by a scan tool), and there is an incredible amount of information there (speed, battery SOC, latitude/longitude, elevation, accelerator/brake pedal position, etc.).
