Great value for the money.

It reads the check engine codes and even looks them up on the internet for you.

When you load the TORQUE app, it takes about 30 seconds before it starts reading the car's computer, but then it streams all data live in real time. It also displays all of the engine stats live. Such as MPH, Fuel level, MPG, RPM, you can customize what to show and how to display it.

The adapter even works with your phone via bluetooth, so you can use it on your other cars, if needed. It reads hundreds of stats - you will never use all of the features that it has, but it is great that it has them all.

There are even displays that save your maximum and minimum readings and you can set warning alarms. In case you are watching the engine temp or just timing your best 0 to 60.

Here are the steps listed below if anyone is having connection issues with the device. It's especially common if you forget to remove device after swapping out your battery.

1) Open Bluetooth 2 and delete all the paired devices.

2) Unplug the OBD2 and replug it into the OBD interface of your car.

3) Pair and connect Bluetooth 2 with the OBD2. There will be a message "Pair with OBD2" popping out to ask for password when you connect the OBD2 to Bluetooth 2.

4) Check if the OBD2 indicator light is on.

5) Open the torque app to see if data can be displayed on the app.
