In the previous app update for Android (version 2.2) and Windows Phone (version 2.0) we added support for multiple control units. The most common and usually the only control unit is the Engine Control Module. However, newer cars are starting to have more than the ECU responding to OBD2 requests. Most cars with automatic transmission have Transmission Control Module (TCM) available for example. There can be also other controllers depending on the manufacturer and model.
Our desktop software has had the support for multiple control units for ages but with the last update we brought the support to the mobile versions too. As with all mobile version updates, this update is completely free for all of our existing customers using the app in these platforms.
In Android, the selection of control unit was added as dropdown spinner in the action bar. The screenshot illustrates a vehicle with three control units available. The selection can be made by opening the spinner by tapping the title and then selecting the appropriate control unit. The selected control unit is visible in every view where it matters and where it can be changed. After changing the control unit, the view data is refreshed from the car and information is shown for the selected controller.
In Windows Phone, the control unit selection was added to the navigation page. The controller can be changed using the list picker on top of the navigation page titled “browse”. To change the control unit, you need to come back to the browse page and do the change you wanted. The screenshot is from the same car as the Android screenshot. The car has three control units and the first one is selected. The acronym of the selected control unit is indicated on top of the view in the title.
Now it’s good time to update your app to the newest version. Remember that as with all the other features, your car needs to support multiple control units for them to show up in the app. If you have only one ECU listed, then your car has only one ECU responding to the OBD2 messages. Happy diagnosing!
An update for OBD Auto Doctor WP8 version was just published few hours ago. The update adds dashboard with some neat gauges to the app. On top of the screen there are speed and RPM meters. At the bottom there are four gauges displaying various information. The gauges may vary a little bit depending on what sensors your car supports. The update is ready for download from Windows Phone Store.
With the free version, only the speed, RPM and Engine Coolant Temperature are displayed. If you want access to all of the gauges, then upgrade to the Pro version.
In addition to the gauges and meters, the update fixes a disconnect issue with some adapters where the adapter closes the connection after certain idle period.
If you still haven’t tried the app, now it’s good time to try it out!
The first version of our OBD-II app for Windows Phones was released about 11 weeks ago. We are very pleased that we chose to support Windows Phone 8 ecosystem since we’ve got over 10,000 downloads for the app this far. It’s great to see that there are so many car enthusiasts in the Windows Phone community too!
The app has got very nice welcome among the WP8 users. The feedback for the app has been positive and we highly appreciate it. Here are the top 10 reviews. Thanks for the wonderful feedback, this is what keeps us going!
OBD Auto Doctor Windows Phone reviews: Top 10
Wow. A real developer of real and usable apps! Great job. Get the upgrade.
Works well. I like that there have been updates with new features. I am using an 8x with BAFX PIC18F2480 Bluetooth device (got it from Amazon).
As of version 1.21 the problems with Lumia 920 are fixed. In case of problems just contact to the developers that are really great and respond quickly! Now it works with my Toyota GT86 by iHarbor mini adapter from Amazon on the Lumia 920! Super!
Top. Read errors and delete works (Audi, Seat, Honda, …) with a cheap ebay adapter. HTC 8x
Good app, prob best obd tool for windows phone
Very good and fast
Seems to work well with my Lumina 521 and ELM 327. I upgraded to Pro. Looks like the best OBD tool I’ve seen for WP 8.
ASE mechanic here…this is a very good price. You’ll save the money in repairs. Knowledge is power.
Works perfectly with my 1020 & cheapo BT OBDII adapter on my A4.
Excellent app. I bought an OBD2 so I could right this app but there’s no reason to compete. This app is that good.
We will continue to work with the app to bring you improvements and new features. You can leave your feedback or improvement ideas to the comments. We would love to hear from you!
The OBD-II diagnostic app for Windows Phone 8 has been updated once again. This update contains some neat improvements and additions that you have been requesting. The update is ready for download from Windows Phone Store.
What’s new in version 1.2 of the OBD-II diagnostic app?
One of the new features is the possibility to send the diagnostic information via e-mail. This helps you a lot since you don’t have to copy the DTCs by hand anymore. No messages are sent automatically, the message field is just pre-filled with diagnostic info and you get to select the recipients and press the send button. You can share the info with your mechanics or friends easily. Below is sample email produced and sent by the app.

Another neat feature is the added support for WiFi adapters. If you have one of those Wi-Fi scantool adapters, you can use OBD Auto Doctor with it now.
The third important addition is the troubleshoot module. The troubleshoot module helps you to resolve connectivity issues. It is also possible to send the logs to us for further analysis. If you have any connection issues, you should try this!
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.
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!
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.
Download the update and start saving fuel, money and nature!
OBD Auto Doctor OBD2 app for Windows Phone is now available from the Microsoft app store!
The app is available for free so that you can make sure it works with your adapter and car. You can read Trouble Codes (confirmed and pending), Freeze Frame and reset MIL with the app. You can also check readiness monitors and monitor various sensor values. And more features will be implemented in future.
The free app contains some limitations, however, that you can unlock by upgrading to the Pro version using in-app purchase. In-app purchase is convenient way to buy the app without need to re-install separate version.
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!
