On-board car computer has been popular for many years. Car owner can learn about more data

beyond the regular dashboards by it, but the install is not convenient. Recently one of my

colleagues bought a device called iOBD2 that is easier to install and has more functions. Today

we will introduce this gadget.

What is iOBD2?

In fact, wireless OBD diagnostics is not something new, but it has not been popularized. iOBD2 is

a vehicle diagnostic system combined of iOBD2 adapter, smartphone and iOBD2 app. Its biggest

feature is convenient. With wireless connection, you just need to plug the iOBD2 adapter into

the OBD2 connector and install the iOBD2 app on your phone. Then it turns your phone into a

portable on-board computer, reading car engine data such as engine speed, water temperature

and average fuel consumption when the car is driving. In addition, you can use it as speed timer

as well. Now we take a simple analysis on this device.

3.Set Wi-Fi connection

The iOBD2 adapter connects with the phone by Wi-Fi. Once the app installed, open the app,

click connection button and select Wi-Fi option, in a moment the car model information will be

displayed. The connection is complete when Wi-Fi indicator appears on the status bar of the

phone. With a clear and simple layout, the UI is impressive.

Function 1. Diagnosis

The most practical function in this feature is read trouble codes. Once there are any codes, you

can clear the codes before going to a mechanic. Function like vehicle information is not so

practical.

3. Performance test

With this feature, you can test the results of acceleration by setting an initial speed to the end

speed. In order to see the accuracy of the data, we take a 0 to 100km/h test. The result is 0.34s

discrepancy with that of professional test instrument, which is a little surprise for us. Although

there is some discrepancy, it is enough for the ordinary users to get a reference.

Shortcoming After trying iOBD2, we find one of the most inconvenient is that if you press the Quick do or

Home button when driving the car, iOBD2 will be disconnected. You have to select Wi-Fi

connection again each time you enter the app.
