OBD2 Software for ELM327 is a free program that allows you to use your PC and a hardware interface to get the information from your car’s computer.The program is very user-friendly, and easy to learn.
Note:anti-virus software can flag up this obd software as having a virus. This is a false positive and is due to the obd software containing the application file like .exe. So Before setup the device software, please disable/uninstall anti-virus software or install a more reliable virus scanner!
The iPhone, iPad , and iPod continue to be very popular ways of interfacing to the ELM327.
One word of caution though – the Bluetooth that Apple uses in iOS devices does not currently support the Serial Port Protocol (SPP). As such, iOS devices can not connect to ELM327 modules with Bluetooth – you must use WiFi with your device*
BlueDriver claims to be able to use the iPhone or iPad’s Bluetooth circuitry to connect to the scan tool. The catch is that we couldn’t get it to work with any Bluetooth modules that we tried. It seems that if you want to use this software, you will also have to buy their special OBDII interface module.
This app continuously monitors several engine parameters, but it’s not clear how you can modify (or stop) them. It does allow you to define custom PIDs though, which might be handy (depending on just what you are using the scan tool for).
* We are aware that older iOS devices have serial data available at the 30 pin connector, but do not know of any software that you could use to take advantage of it.
There’s a large number of Android Apps for talking to the ELM327. We’ve had to pare it down to a few of the most popular:
Note that most Android software requires that you already be paired with a Bluetooth device. We are often asked about pairing codes and while we can never know exactly what code would apply to your interface, we can say that most use either 0000 or 1234.
