The most useful part of OBD II is in it's capability to read real time information directly from your vehicle, even while the vehicle is in motion. Using OBD II we can even read trouble codes and monitor real-time statistics such as RPM, vehicle speed, etc. There are a range of different OBD II reading devices on the market varying from cheap basic code scanners to very expensive but highly advanced professional units that can even calculate MPG as you drive. We use the highest available. Anything less is simply a waste of your money and time!
