You should try a smart phone app called torque pro. They have a free one but I bought the $5 app. Then you buy the $15 blue ODBII plug-in and you are set. It tells you EVERYTHING. IAT, TPS, intake air temp, coolant temp, O2 readings, O2 volts, O2 temps, rpm, speed, engine codes, gps with speed monitering, engine graphs, torque/hp being used and more stuff I cant think of. You can customize your screens and gauges. Like have your O2 gauges on one screen and then swipe over to your temp sensor screen...its just a nice a$$ program for 20 bucks. The cool thing is that you can just unplug it and plug it into the next ODB11 port on the next car and read the same stuff without programming anything.
