OBD2 software for Symbian, MeeGo gets fuel economy

Fuel economy sensor in action

It’s been a while since the last update of our Symbian and MeeGo OBD-II software versions. Yet we haven’t forgotten you. Quite the opposite, last week we rolled out a new version for these platforms including fuel economy sensor. The version for Nokia N9 was approved last week already. Today we got informed by Nokia that the Symbian update was approved and is ready for download from the Nokia Store. Some of you may have tried the new versions already. We have got some feedback and thanks for keeping it in par with the Android version.

What’s new in 1.6?

The most interesting feature here is the fuel economy. Fuel economy is not reported by majority of cars. Instead, it has to be calculated using other sensor values. For cars using gasoline, we use air flow rate from mass air flow sensor or intake manifold absolute pressure and intake air temperature plus other needed sensor values. For diesel engines, the fuel economy calculation is based on calculated engine load and air flow rate from mass flow sensor.

There are few new settings related to the fuel consumption calculation that you might want to check:

  • Fuel correction factor: general 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%. Change this only if you know what you are doing.
  • Engine displacement: This is the volume of the engine in liters. Change this to reflect your car!

Update for Symbian finally here

Get software update for Symbian

It’s finally here! A software update for Symbian devices is here to be downloaded.

First of all, we are extremely sorry for the long delay with the update. Nokia had some massive issues with the approval process and therefore the update was delayed due to reasons that had nothing to do with us. Nokia had given our applications unique identifiers (UIDs) that they had given to some else too. As the name suggests, the UIDs should be unique but in this case they were not. For this reason you need to completely re-install the application.

  • First, uninstall the current version from you phone.
  • Secondly, open the store client and install OBD Auto Doctor again.

If you don’t uninstall the old version, you will have two instances on your phone. Due to the UID issue, a regular update won’t work. The same procedure works for both the Lite and the Pro version. You can safely uninstall the paid Pro version and install it again from the Nokia Store. You don’t need to pay for it again. Also if you have previously tried to install OBD Auto Doctor and the installation has failed so any reason, please try again with this updated version. The UID issue is the most likely reason for this installation failure. We are terribly sorry about the manual re-installation process that you need to do. If you have any difficulties with the re-installation, please don’t hesitate to contact us.

This update includes the same improvements as the version for N9. In addition it also contains some important user interface fixes for Nokia Belle users.



OBD oscilloscope and new Symbian devices

We are glad to announce that the OBD Auto Doctor for Mobile is now available for new range of devices. The OBDII app is available for all recent Nokia Symbian (Symbian^3, Symbian Anna and Nokia Belle) phones in addition to the Nokia N9.

At the same time, version 1.3 of the software was released. The improved version includes some new features. The main new features are:

  • Visual view to the sensor values. The sensor graph view is kind of oscilloscope providing a visual view to a sensor value. The graph is superior to numeric info when you are interested in following the changes of a sensor value. The graph shows a 30 second window to value history.

  • Ability to send diagnostic information, including Confirmed Trouble Codes, Pending Trouble Codes, and Freeze Frame Trouble Code and parameter snapshots via e-mail or SMS. This improves the usability and 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.

  • Now you are able to choose the used protocol for OBD-II manually. The existing fully automatic selection works for most vehicles but for some cars the manual selection provides better results. If you are not having any troubles with the automatic protocol detection, you should continue to use it. On the other hand, if you are not able to connect to your car, you might want to try the manual selection.

The mobile software is available from Nokia Store.



OBD diagnostic software for Symbian available

It’s finally here! After waiting for three weeks for approval to Nokia Store the OBD2 software for Nokia Belle is finally available for download and purchase. At the moment the approved Nokia Belle phones are Nokia 500, Nokia 603, Nokia 700, Nokia 701, Nokia C6, Nokia C7, Nokia N8, Nokia Oro, Nokia X7 and Nokia E7. Unfortunately Nokia has some compatibility issues with Nokia Anna and the app store so Nokia Anna owners still have to wait for the software. We are truly sorry about this as we would also like to get the app published for Anna.

Please note that we can’t reply to you if you only leave comment on Nokia Store reviews. If you need help or want response to your message, just contact us.

Feel free to post any improvement ideas to the comments!



Coming up next: OBD software for Symbian

We have got several requests for supporting Nokia Symbian phones since the release of the mobile version for N9. Your voice has been heard. Now it is official, OBD Auto Doctor for Mobile is coming up next for Symbian phones. Symbian Anna, Belle and later phones will be supported. It means phones such as Nokia C6, C7, E7, N8 and several others.

We just need to polish and test the app little more and them submit it for Nokia quality assurance. The plan is to release the diagnostic software to Nokia Store during December. The features and outlook will be identical to N9 version with one exception. The Symbian version does not have the option to use WiFi for connectivity. However, Bluetooth is available and I think almost every wireless OBD scantool adapter in the market is Bluetooth based.

Hang in there all Symbian owners. No more than few weeks until you can start diagnosing your vehicles!
