I have the ELM 327 bluetooth with the torque app, it's pretty simplistic but it works well for $12. The speedo is pretty close to actual on the highway, and you can set up a screen of whatever supported PID's you want. Did the car in question come with the trans temp sensor? I don't think you can add additional inputs and create your own PID like in hptuners
