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!

Mobile version 1.5: Diamex DX70 and clone scantool adapters

OBD Auto Doctor has been updated once again to bring you new goodies. This is rather small update but it contains some important features that many of you have been requesting. The update is ready for download at Nokia Store!

New in version 1.5:

  • Support for Diamex DX70 Bluetooth adapter
  • Improved support for clone scantool interfaces. This includes better support for high end clone adapters as well as improved support for cheap clone interfaces.
  • New OBD2 parameters (see full list of supported OBD parameters)
  • Screen backlight settings
  • Some visual improvements

The new version got already some nice feedback: “…fast, intuitive ui, and reliable, love it” by deviantdariot. Try out the software yourself and tell us what you think!



Software update: Fullscreen OBD scope plus OBDKey support

The newest version of our OBDII software for mobile has been available for N9 several weeks now. Unfortunately Symbian owners need to still wait. Today, the app has been waiting for approval in Nokia Store QA for one month. We decided to publish this post even though the Symbian version is not available yet. Nokia has some serious issues and can’t even give an estimate when it will approve the update. We will make a new post as soon as the new version is available for Symbian^3, Symbian Anna and Nokia Belle devices too. We are terribly sorry about the delay.


Fullscreen OBD scope


The version 1.4 of the software includes improvements and features such as:

  • Oscilloscope improvements; now the OBD scope is automatically scaled to proper scale. Previously the scale was fixed and showed the whole scale of the possible parameter values. Another neat feature is the fullscreen scope. To open the fullscreen view, just click the graph of in the Sensor Graph view and the view will become fullscreen.

  • This version includes initial support for OBDKey scantool adapter. The very early OBDKey 1.1 and 1.2 versions might still not work. We are resolving the issue with the OBDKey manufacturer. However, the currently available OBDKey 1.4 works without any issues. OBDKey is now one of the officially supported adapters for the mobile version.

  • We also added a feature to help resolving possible connectivity issues that some of you might have. A troubleshoot log is available under Information – Troubleshoot Information. By default the log is turned off to save resources. If you are having issues connecting to your car, just turn the troubleshoot log on from the settings and send the log file to us from the Troubleshoot Information view.

The next version of the software is already cooking. It will contain tools for monitoring fuel economy among other improvements. Feedback is always very welcome, leave yours on the comments.



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 Auto Doctor for Mobile updates

The anticipated Live Sensor Data feature has arrived for OBD Auto Doctor for Mobile in version 1.2. Every sensor supported by a car can be selected and monitored in this Sensor Data view. The update frequency depends on the amount of active sensors. The more sensors you select, the slower the update rate becomes. To make the updates more frequent, select only the sensor you really want to monitor at the moment. The sensor readings are available in both metric and imperial units.

Dragstrip


Another new and exiting feature is dragstrip timing. With this feature, you can measure the performance of your vehicle. A new and innovative way to start the measurement is auto-sensing. In auto-sensing, the app polls vehicle speed sensor and trigs on movement. The timing can also be started by traditional timing lights. Four red lights will light with fixed period. Then, after some random time, the lights will go off. That is the moment when measurement is started and you should hit the pedal. You should only use the drag strip feature on a close racetrack.

The Sensor Data and Dragstrip features are fully working only in the Pro version. We have also got queries whether the new upcoming features will be free for existing customers. Yes, all future releases will be free as long as you have purchased the app once.



OBD Auto Doctor Pro for Mobile now in Nokia Store!

OBD Auto Doctor Pro for Mobile

I’m glad to announce that the Pro version of the OBD Auto Doctor diagnostic software is now available for purchase from Nokia Store.

The work to improve the software and add more features is on-going. One reviewer pointed out that the app does not support live data yet. Well, I can tell you that the next version will have the feature (see the live sensor data screenshot). The next version will also have an option to choose imperial units instead of metric units, and more…
