Makes it easy to connect to the CPU of the car to perform various diagnostics. Displays accurate readings of the oxygen sensor.

On-Board Diagnostic systems are widely-used by car mechanics and repair technicians, despite the fact that their software components are usually quite intricate and require some previous knowledge and training in order to be used effectively. That’s not the case with OBD2Spy, as anyone can use it without any problem right from the beginning. This OBD program manages to keep things simple thanks to its self-explanatory interface. Furthermore, it’s not only easy-to-use, but it will also work with the most popular diagnosis interface types: ELM (ELM-USB) and mOByDic.

When it comes to its features, there’s nothing to complain about. I personally enjoyed the simulator that allows you to see how the program works even if you can’t connect it to a vehicle at that precise moment. Also, the real-time gauge display is quite appealing, especially for beginners like me.

The quarter mile acceleration simulator is another interesting feature that allows tuning and analyzing the performance even of modded engines, not only of the factory default ones. OBD2Spy also offers the possibility to export the report containing the entire diagnosis information to an HTML file. Accurate oxygen sensor monitoring tools and tests are also featured, as well as a bit calculator, a DTC (Diagnostic Trouble Code) finding tool, a terminal that allows sending data manually to the vehicle, and more.

As a general conclusion, OBD2Spy will show you that a user-friendly OBD software can be a reality and not just the wish of many people.
