Car diagnostic software update for PC and Mac

Our car diagnostic software for PC and Mac was updated about a month ago. The latest OBD Auto Doctor is now labeled as version 3. It took few weeks to publish this blog post. But it’s never too late, right? Let’s go through the change log for the update.

Improved User Interface

The new version has redesigned and improved user interface. This is of course the main visible change for you. We clarified the views with more white space and trimmed down the titles. We also reorganized the views under new categories. The new categories are summary, trouble codes, diagnostics, monitoring and extras. The categories have new flat style icons too. These changes make it easier for you to find the stuff you are looking for. We also added help texts to the views. They provide you helpful details about the information that the views provide. Just move your mouse over the small white question mark to get the hints.

On-board System, Test or Component activation

The software has now support for OBD2 mode 8. The mode 8 is the on-board system, test or component activation service. This service allows bi-directional communication to start or perform specific tests. This is different from the most OBD2 services because they just read information from the car. In that sense, this service or mode is a rather powerful tool.

The current version of the OBD2 standard defines only two tests. OBD Auto Doctor supports these both:

  • Evaporative system leak test
  • Diesel Particulate Filter (DPF) Regeneration

It’s expected that more tests are added to the standard in the upcoming updates.

Sensor Graph Grid

The graph grid is the newest addition to the monitoring tools. You can now track up to four different sensors side by side with the Sensor Graph Grid. Each sensor has separate graph with it’s own scale. This makes it easier to interpret the data in some cases.

Other changes

We did a lot of other smaller changes for the software too. The following list highlights the most important ones.

  • Increased number of the simultaneous sensors in the graph. You can now update up to 6 sensors at the same time. We also improved the automatic scaling of the graph scales to make it easier for you to interpret the values.
  • Added support for the Readiness Monitor status for the current drive cycle. This is in addition to the monitor status since the trouble codes have been cleared and the MIL has been reset.
  • Verified support for the new Windows 10. We also tested the OS X El Capitan preview version for possible compatibility issues.
  • Improved internationalization with all the strings updated by native speakers. Because of high maintenance work we had to remove support for some languages with fewer users.
  • Improved functionality with some clone adapters. The problematic adapters reporting version 2.1 will work now too. We do recommend though that you use a high quality genuine ELM327 adapter. Some clone adapters have serious issues delivering data from the car.

Windows 10 compatibility with OBD Auto Doctor

OBD Auto Doctor and Windows 10
Microsoft released it’s latest operating system called Windows 10 just at the end of July. We here at OBD Auto Doctor have been working hard to make sure that you can continue to diagnose your car with the new and shiny Windows 10.

Feel free to update to Windows 10 and be assured that OBD Auto Doctor continues to work as before. If you, for any reason, find anything that doesn’t work, please send us a message. We also advice you to use the latest version of our car doctor software. It’s guaranteed to be fully compatible.





OBD Auto Doctor works with the new Kiwi 3 OBD2 adapter

We are pleased to announce that OBD Auto Doctor will be compatible with the new upcoming Kiwi 3 adapter. Kiwi 3 is the next generation of OBDII adapters and no longer requires cumbersome bluetooth pairing or wifi configurations. Simply, plug and launch the OBD Auto Doctor app.

The smallest, fastest, most versatile OBD adapter yet

Kiwi 3 promises to be up to 4 times faster than the nearest competitor and uses ultra low power allowing you to leave your device installed permanently in your vehicle. The adapter is compatible with all standard OBDII protocols, and it has support for firmware updates via Bluetooth. Kiwi 3 has very small form factor and employs a nearly invisible design. When inserted into your OBDII port, Kiwi 3 sits just 0.68 inches thin making it the smallest and most discrete OBDII adapter.

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.
