Windows, Mac OS X and Linux version 2.0

OBD Auto Doctor for Windows, Mac OS X and Linux was previously updated to version 2.0. The new version contains a lot improvements. Some of them are visible to you but there are several improvements done under the hood, too. The latest version has now better support for the new Windows 8.1 and Mac OS X 10.10 Yosemite operating systems.

Exporting capabilities

One of the additions to the software was the data export capabilities. You will be now able to export Diagnostic Trouble Codes and Freeze Frame data to a text file. You can then easily share the file, or archive it for documenting the history of your car.

Moreover, you can export the sensor live data to a *.csv file. The csv file can be opened with spreadsheet software such as Microsoft Excel, Google Sheets or LibreOffice Calc. You can record a whole drive cycle and review the results afterward to detect some abnormalities with the sensors of your car. You can even draw a custom graph with these external tools from the data you collected with OBD Auto Doctor.

We did an example drive with 2014 Audi A3 1.4 TFSI and recorded the car data during it. The granularity of the data is rather coarse because we recorded 28 sensors simultaneously. Dropping the amount of different sensors will improve the granularity significantly. That’s because it leaves more time to update the interesting sensors more frequently.

Other new features

In addition to the export functions, the latest version added support for 16 new OBD2 parameters. It’s also now possible to graph more than one sensor or parameter simultaneously with the oscilloscope. Last, OBD Auto Doctor user interface was translated to Polish.

You can download the latest version of OBD Auto Doctor from the download page.





OBD2 parameters added – download the update

The latest software version for every supported platform (Windows, OS X, Linux, Android, iPhone and Windows Phone) added support for 16 new OBD2 parameters. These parameters are implemented according to the latest OBD2 standard version (SAE J1979 AUG2014).

Adding these new parameters increases the value of the OBD2 software you have. All these parameters are available for our existing customers totally free. Just remember that in order for the software to be able to show the values, your car needs to support the sensors too. Typically, the newer the car the more values it supports.

With these new parameters, you will get even more out of your OBDII software. Grab the update from our website or from the appropriate mobile app store.

OBD WiFi adapter support in Android

The latest update of OBD Auto Doctor for Android added support for OBD WiFi adapters. So now the Android app supports both Bluetooth and Wi-Fi adapters. Although not as easy to setup as Bluetooth adapters, Wi-Fi adapters are good choice for those who consider switching from/to iPhone. The price of the OBD Wi-Fi adapters has considerable lowered in the last couple of years, which has brought the adapters to the awareness of new consumers.

Wi-Fi vs Bluetooth OBD adapters

One of the benefits of Wi-Fi adapter is that it allows very fast data rates. It means that your sensors will update faster in the app screen, for example. Another advantage is broad support on different platforms. The wifi adapters are supported in every platform so you can use them with OBD Auto Doctor iPhone and Windows Phone versions and with the desktop/laptop version as well.


Wifi adapter settings


One of the drawbacks compared to Bluetooth adapters is that Wi-Fi adapters are not as easy to setup. First, you need to connect to the network created by the adapter. Only after that you can use the app to connect to the adapter and car. The procedure might seem a bit tricky at first but it will get easier after you have done it a couple of times. To help and guide you through the first time, we made a short Quick start guide for WiFi adapters to get you started with the app and adapter.

Happy diagnosing!





OBD2 app for iPhone released

OBD Auto Doctor OBD2 app for iPhone is now available from the Apple app store!

The app works now perfectly even with the new iOS 8 released just few weeks ago. The very first version of the app had some layout issues with iOS 8 but now all those issues are gone. The app works fine with iOS 7 too but older versions are not supported.

The iPhone version of the app requires separate ELM based OBD adapter using Wi-Fi connectivity. Due to technical limitations of the platform Bluetooth adapters can’t be supported. To get started with the app and adapter setup, please check the Quick Start Guide for iPhone. It will guide you through the first time usage.

The basic app is available for free so that you can evaluate it and make sure it works with your car and OBD-II adapter. The free app has some limitations though. You can unleash all the features and upgrade to the Pro version using in-app purchase. In-app purchasing is convenient way to unlock the Pro features without need to re-install separate app version.

Upgrading to the Pro

Getting the Pro version can be done inside the app using in-app purchase. It’s one time purchase that covers all future feature updates and additions to the app. The purchase is tied to your Apple account. You can get the Pro version back even if you upgrade your phone or uninstall the app by accident. Just install the free app from the app store and it will automatically detect that you already own the Pro version. The only thing you have to do is use the same Apple account in your phone.

Unfortunately Apple doesn’t provide us means to issue refunds of the purchase. Therefore, please try the free version first to make sure there are no compatibility issues with your adapter or car. The issues are very rare but if the free version doesn’t work, the Pro version won’t make the situation any better.

Try it now and Enjoy!
