Fuel economy for Windows Phones

The first version of our OBD-II app for Windows Phones was released about a month ago. Today, I’m happy to provide you more. The first update for the app, version 1.1, is available from the Windows Phone Store now. The update contains some nice additions such as fuel economy and other smaller improvements.

Fuel Economy

The best part of the update is fuel economy for gas and diesel cars. Most cars don’t report the consumption via OBD as standard parameter. Therefore, the consumption must be calculated from other sensor values. For cars using gas, we base our calculations on MAF air flow rate or intake manifold absolute pressure and intake air temperature. For diesel engines, the fuel economy calculation is based on calculated engine load and MAF air flow rate.

The app contains some new settings related to the fuel economy. First of all, the app detects the used fuel type automatically. However, if the consumption value seems to be totally off, you might want to set it manually. The other parameters you might want to check are:

  • fuel correction factor: factor that is used to multiply the calculated economy. Change this only if you think the calculated economy should be fine tuned.
  • volumetric efficiency: For modern cars the VE is about 85%, for older cars it might be little lower such as 75% or 80%. You need to change this only if you know better value than the default.
  • engine displacement: This is the volume of the engine in liters. Change this to reflect your car!

Personalization

Another thing we improved in the app is personalization. Now you can select the avatar image from the gallery too. This is in addition to taking new photo with the camera.

This feature was actually one of the user requests we got from the first version. Please keep sending your improvement ideas and feedback to us. We’ll work hard to make this app the best OBD app for Windows Phones.

OBDII sensors

Few words about the sensors. First of all, your car needs to support specific sensor in order it to show up in the selection view. If you car doesn’t support a sensor, it will not be shown in the view. The selected sensors will be read one after another. The update speed of the sensors depends much on the used adapter. The better adapter you have, the faster the values are updated. This also means that the more sensors you have selected, the more time it will take to get specific sensor updated. The sensors are updated at maximum speed in the same order they are visible to you.

Tapping a sensor name in the view will open graphical presentations of the data. See the screenshots above. Please note that the graph view will be opened only for sensors that have numeric value. If the sensor contains non-numeric value, tapping the name won’t do anything.

Upgrade to the Pro

The upgrade to the Pro version can be done inside the app using in-app purchase. The future updates of the app will be free for all existing customers who have upgraded the the Pro version. The purchase is tied to your Windows Phone account. If you change your phone or uninstall the app by accident, you can always get the Pro version back automatically just by installing the free app from the app store. The only thing you have to do is use the same WP account in your phone.

Unfortunately Microsoft doesn’t provide us any means to issue refunds of the purchases so please test the app with you car before upgrading just to make sure there is no compatibility issues.

Try it now!

The app is available for all Windows Phone 8 devices. Enjoy!

Windows Phone OBD-II app coming in few weeks

It’s my pleasure to announce that we are about to conquer yet another mobile platform with our OBD app: Windows Phone. We’ve got multiple requests to support Windows Phone ecosystem and the wishes will become reality soon. We have worked hard to come up with the best OBD software for Windows Phone devices. Due to technical limitations the older WP 7.x devices won’t be supported but all WP 8.x devices will.

We are targeting the end of August for the release. The app is quite ready with just some tuning and optimization to be done. The initial version will cover Diagnostic Trouble Codes, Readiness Monitors, Sensors and other information. More features and functionality will be added in upcoming versions.

New version of our car diagnostic software for Windows and Linux is available for download. We recommend that you update your existing installation to this one. The new version contains several improvements and new features compared to the previous version. The following list contains the most important additions.

What’s new in the version 1.6?

The software is compatible with Windows 8, 7, Vista and XP. For Linux, *.deb and *.tar.gz packages are provided. Try it out yourself!





OBD graph for Windows and Linux

The release date of the next version of OBD Auto Doctor for Windows and Linux is coming closer. We would like to give you a short preview of the most important feature addition made to the software: OBD data graph aka oscilloscope.

With the OBD oscilloscope, you can visualize sensor value changes easily. Graphs are great tools because they communicate information visually. Even large amount of data, or fast changing data can be interpreted much better when expressed as a graph. Graphs help you to identify sudden spikes and trends in the data.

In addition to visualizing the numeric OBD data, our software enables you to save the graphs to your computer as image files. You can share the images with your mechanics or friends, or you can post them to automotive forums when asking repair advice from fellow DIYers. The screenshots in this post are saved by OBD Auto Doctor.
