Version 113: The December Release


We have had many releases since version 102, but we haven’t written about them here. Sorry about that!

Since we are now working closely with Track Attack, we are often releasing software in lock-step. This release is such an example. Version 113 is available for Alfano and Track Attack at the same time.

Changes in the Alfano Version

Off Camber Data for Alfano has seen a few changes and updates since the last version:

  • When selecting a new lap, the graph now remembers its zoom level. This makes it much easier to compare only a small section of the track across many laps.
  • Similarly, when you click on the graph to set a reference point, the zoom level stays. In the old version it always zoomed out to show the whole lap.
  • When importing AiM data with a throttle position channel, sometimes it would read the position as a number from 0 to 1, and other times it would read it as a number between 0 and 100. We now made this consistent, so that it works the same as all other throttle positions from other data loggers.
  • When you’re aligning video and data, there was a bug where at first, the video would show a black square. This is now fixed.
  • Similarly, when you’re done editing the video alignment, you would have to deselect a lap, and then select it again to make the video show up. That’s also fixed.

You can get this new version from our download page at, or simply restart your version of Off Camber Data.

Changes in Track Attack

Version 113 of the Track Attack software has all the same fixes as the Alfano version, plus a few more:

  • Track Attack now supports the CSV format from the Race Technology family of data loggers.
  • Some users noted that sometimes, iRacing sessions would come out without a GPS speed channel. This is now fixed.
  • The previous versions of the software had a problem with really long sessions, such as 12h endurance races. We’re still not perfect in these cases, but this scenario is working a lot better now.

You can get this new version from the Track Attack download page at, or simply restart your version of Track Attack. Also, remember, you can run Track Attack and Off Camber Data side by side!

Version 102 for ALFANO 6

Race Car #102We have a new version of Off Camber Data for ALFANO, and the big thing in this version is support for the ALFANO 6!

We realize we are a little late with this, but we had a lot of problems with the different Bluetooth implementations on different PCs. We tried to fix as many of these as we could, but we know there are still some problems, particularly with the Mac. That said, ALFANO 6 support already works great on most computers, and so we thought it is better to release this version now, so most of you can already reap the benefits.

If you are one of the unlucky few that have problems getting it to work, please let us know as soon as possible at

We still managed to include a few other improvements in this version:

  • There are quite a few performance improvements, especially for people with lots of sessions.
  • While synchronizing with the Track Attack server, the “sync” button in the corner now shows progress.
  • We added a new “Combo G” math channel.

You can get this new version from the ALFANO downloads page, or simply restart your old version of Off Camber Data. If you would like to contribute, feel free to comment on the blog, or send us an email at!

Version 98: Track Harder

98For Off Camber Data, this is the 98th time we release a new version, but it is only the second release with our partners from Track Attack. Predictably, we found a lot of things to fix with the new features, so we went to work and fixed as many of them as we could:

  • A lot of performance fixes. Especially on Windows, there is a problem with performance when synchronizing many sessions at once. To deal with this problem, we slowed down the speed of the upload, so that the program remains usable. That means that uploads take a long time, at least until we find a proper solution. If you have many hundreds or even thousands of sessions, we recommend you let it run for a few hours once, so that it will catch up.
    We know there are other performance problems in the program. We have some more fixes in the pipeline, but couldn’t get them ready in time for this release. Watch this space for future updates!
  • Tags now synchronize properly between different computers.
  • Synchronization can now be paused. If you are at the track and your internet connection is really slow or expensive, you can click in the bottom right and select “Pause syncing”, to turn off synchronization completely.
  • When you select a run, OCD now shows you the synchronization status of each run. That way, you can make sure that your runs are properly uploaded to the server.

We also made one change that has nothing to do with Track Attack: The ALFANO version can now parse the CSV format from the mobile app. This should help out all the people who use both the mobile app and OCD at the same time.

Finally, we are upgrading all users of the OCD Starter Edition for Unipro to the Advanced Edition, for free. If you are one of those users, you don’t have to do anything to get the new version. When you get the update, you will see lots of new features and modes. We hope you’ll like it!

As always, you can get the new version from the downloads page, or simply restart your old version of Off Camber Data. If you would like to contribute, feel free to comment on the blog, or send us an email at!

Version 95: Attack of the Tracks

Lightning McQueen #95As far as releases go, this is probably the biggest one we’ve ever done. This is the first version that integrates the Track Attack cloud directly into the OCD software. With this feature, you can synchronize your data between all your computers, or compare with other drivers in your team. You can send data to your engine builder or driving coach, even if they are not at the track themselves. And of course, you never have to worry about losing the data when your laptop gets stolen or your hard drive dies. As soon as you log back into your account, it’s all there again.

When you first start the program, you will see a big “Track Attack” button in the top right corner of your screen:

When you press it, it will walk you through the process of creating and setting up your account at Track Attack, and you will have an option to import all your existing data into the Track Attack cloud. Don’t worry! If you are using the Unipro or ALFANO version of OCD now, all your data is set up to be “secret” by default. If you want to change this, and give someone else access to your data, you can right-click on the run, click “Share”, and configure who gets to see what in a dialog that looks like this:

Track Attack Share Dialog

In this example, I shared my best session from last September with my team, and with Matt. This session will show up automatically in their copies of Off Camber Data. In the other direction, if they share something with me, it shows up in my copy of Off Camber Data.

We had to make a lot of choices about how exactly to do this integration. Since this is the first release with built-in Track Attack, we know that we will probably re-visit a few of those choices. So if you have any feedback about this feature at all, don’t hesitate to write us back at

This is a big change already, but we managed to add some other improvements to the mix as well:

  • We now have a Polish translation! A new translation is always a lot of work and a remarkable achievement, and I want to give a big thanks to Grzegorz Kręt for getting this done.
  • Importing files is now much faster than before. We addressed some performance issues last time, but we kept going, and found even more improvements.
  • The track map can finally be rotated. Often you want to see the track map in a particular way, or you just want to optimize the space that is there. Now you can!
  • Track Management now has an option to only show tracks that you have runs for. That should reduce some clutter when you have a lot of tracks.
  • We simplified lap selection. It’s much easier to close a run, and there are fewer buttons taking up space.

As always, you can get the new version from the downloads page, or simply restart your old version of Off Camber Data. If you would like to contribute, feel free to comment on the blog, or send us an email at!

On a personal note, I want to thank both the Off Camber Data and the Track Attack teams for getting this done. They have been working on this for almost a year, often long hours and late nights, and it is very exciting to see all that work finally coming to fruition. I can’t wait to see the uses people will find for it!

Version 89: Christmas Edition

Number 89Before the end of the new year, we wanted to get in one more release with all the little goodies and fixes we have built in between the big project. Most of it is little fixes that you will only notice if you’ve run into that specific problem before, but we do have some new features as well:

  • All new language: Portuguese! Big thanks to Francisco Mano for providing us with this translation!
  • Updated language: Swedish! Niclas Andersson always does a great job keeping up to date with the Swedish translation of OCD, and he has done it again. Thank you!
  • When you hover with the mouse over a run header, it now shows you a quick overview for the run.

Run Properties Hover

When you hover the mouse over the run header, it gives you a quick overview over the run.

  • Similarly, you can now change a run’s properties without opening it first. Just right-click in the list of all runs, and select “Properties”.
  • When you click on the graph, OCD will draw an extra cursor, one that doesn’t move with the mouse. You can use this extra cursor as a fixed point of comparison. To help out with this use case, it resets the zero point of the “Time lost” graph as well. Try it and let us know what you think!
  • Some sensors are not as accurate as we suggest in OCD. We made sure that OCD won’t pretend that your temperature sensor can tell the a difference of 0.01 degrees.
  • We put in various performance improvements. In particular, we improved the UniGo file import, the loading times for some of the bigger menus, and deleting many runs at once.
  • We made it a little easier to select a country. We have over 100 countries in the list, so now you can select them just by typing them in, instead of finding them in a list.
  • Users of the ALFANO version can now read the .drk and .xrk files that come from Race Studio 2. This is an experimental feature. We might have to change it or remove it, but give it a test and let us know if it works for you.
  • Users of the Unipro version can now sort the tracks in the track download menu. That seems like a small change, but it makes a big difference when you want to see all the synchronized tracks in one place.

As always, you can get the new version from the downloads page, or simply restart your old version of Off Camber Data. If you would like to contribute, feel free to comment on the blog, or send us an email at!

Version 84: Tracking

84In this release, we focused our attention on the track database. The most important change is that it has gotten much larger, but we’ll keep going until we have at least 90% of all kart tracks in the world covered. Since the track database lives on the internet, you actually don’t need to install a new version of OCD to get the new tracks. Just click the cloud symbol in Track Management, and it will show you all new tracks available. However, with more tracks come more management, so we added a bunch of tools to handle the increased number of tracks:

  • Tracks can now be filtered by country. When downloading tracks from the database, you can choose which countries you drive in, and just download all of those. Of course, you can still select individual tracks, or just download everything, but this is the easiest way to keep organized.
  • Once you get to over 100 tracks, the old OCD would get a little slow when working with the tracks. This version does not do that anymore.
  • Since tracks now have countries, they have flags! This makes Track Management look a little better, and it makes it easier to tell the tracks apart.
  • We made it more obvious that there is a track database. Many people missed it before, so now we show a reminder when you have three tracks or fewer.

Screenshot of various improvements to the track database

We also have some other improvements, in case you’re not as excited about tracks as we are:

  • We re-did almost all of the French translations.
  • We had a rendering bug where track maps in New Zealand would look inverted and awful. This is now fixed.
  • If you’re using the ALFANO trial version, your trial now doesn’t start expiring until the first time you import a session. So don’t worry about experimenting with it in the off-season. You can use OCD totally free until you import the first session, and then 30 more days.
  • Videos are now shown in whatever configuration maximizes the space.
  • Some people with unusual network settings experienced some crashes on the Mac. This is now fixed!

Track Attack LogoAnd then there is one more thing: For a few months now we have been hard at work with our friends at Track Attack to take data analytics to the next level. If you are already using the OCD software, the big new thing is that your data and your video is stored in the cloud, and available on all your computers at the same time. You can easily share data with a friend, a coach, or an engine tuner, even when they are not at the track with you! We’re aiming to bring this to Unipro and ALFANO users early next year, in time for the new season.

To make that happen, we need your help: We have started a crowd funding campaign at Indiegogo. We have various levels of participation, from $5 and up, and they come with various rewards, such as hats, shirts, your picture on a new race car build, and more. If you’d rather have team gear that says “Off Camber Data” instead of “Track Attack”, let us know, and we’ll make it happen!

Version 82: Foundations

82We would like to announce a new major feature with every release of OCD, but sometimes we have to dig back into the code and lay some groundwork for the future. Version 82 is one of those releases. An enormous number of changes have gone into this release, but very few of them are directly visible. Here are a few:

  • OCD now supports GoPro’s “chaptered” videos. When the GoPro records a video that’s larger than 4GB, it splits it into several video files. OCD now stitches them together seamlessly.
  • Speaking of video, when you hit play on the videos, they used to keep playing even when you go off and do something else in a menu or a dialog. It now stops the video when you stop paying attention to it.
  • Finally, when you import a bunch of runs at the same time, OCD asks you what to do with duplicates. It did this before, but the options were confusing. Now, there is a button for the most obvious choice: Import all new runs, and ignore the duplicates.

As always, you can get the new version from the downloads page, or simply restart your old version of Off Camber Data. If you would like to contribute, feel free to comment on the blog, or send us an email at!

Version 78

78You haven’t heard from us in a while, but we’ve been hard at work supporting existing features, making little tweaks all over the place, and adding some new stuff. Here are some highlights:

  • Parsing the AiM CSV format: OCD can now read the CSV format that Race Studio 2 exports. Simply export as CSV, and import the file in OCD! [Please Note: This feature is available only in our Alfano version of OCD.]
  • When importing duplicate runs, OCD is now more clear in its behavior. When you import the same run twice, OCD will tell you during the import. When you’re importing a lot of runs at the same time, OCD will stop the import to let you know there are duplicates. You can then choose to discard them, or import them anyways.
  • When aligning a video with the data, we now make sure you can always see which part of the data is currently playing. It’s a small change, but it should help a lot!
  • We made some improvements to the way that OCD handles data from a steering wheel sensor.
  • Finally, we made some changes to how the delta graph works, for improved accuracy even when the GPS is a little wonky.

Especially for users participating in the ALFANO beta version, we have a few more changes:

  • When you download from the device, you can now choose exactly which runs to download, and which ones to leave on the device.
  • We improved compatibility and reliability of the ALFANO importer. To our knowledge, all configurations of the PROIIIEVO should now work. If you find one that does not, please let us know at!

Version 71: Smooth Operator

71It’s not a big release, but it has a major new feature that a lot of you have been asking for: Custom smoothing.

We have always applied smoothing to some channels, but now you can choose for each channel how much smoothing you would like. You can set the smoothing factor in Channel Management, but there is an easier, faster way: In the graph, right-click on the channel you’d like to smooth, and choose “Properties”. OCD will show you window like the one below:

A smoothing window on top of the graphs

Simply drag the slider left and right. OCD will show the effect immediately. The filter that’s applied is a simple moving-average filter with no delay. We’re planning on adding a low-pass filter in a later release.

Smoothing is great, but it is not everything in this version. Here are some other highlights:

  • Column widths in the current values window are now saved across restarts. It’s a small thing, but I know that for many this makes the Current Values window twice as useful.
  • When you import a single new run, OCD now automatically opens the fastest three laps for you.
  • We put some work into the code that automatically hides in-laps and out-laps. We know it is still not perfect, and it will sometimes get tripped up by truncated laps, but it should be a little better than it used to be.
  • For people using the UniGo 8005, we added a new math channel that takes advantage of the barometer in it. The channel is called “Relative Air Density“, and it is designed to help with tuning the carburetor. As a rule, the denser the air, the richer the air/fuel mixture has to be.
  • OCD can now use AVI files in addition to MP4 files. If you have a video format that you would like us to support, please let us know!

As always, you can get the new version from the downloads page, or simply restart your old version of Off Camber Data. If you would like to contribute, and especially if you have some thoughts on additions to the X/Y plots, feel free to just comment on the blog, or send us an email at!

Version 66: XY

Ford GT #66We have another version ready, full of goodies and improvements. The most visible new feature is certainly the new plot type: X/Y plots. They are a bit basic in their current form, a herald of things to come, but they are already quite useful. Scroll down to see an example configuration!

There is a ton of other stuff in this release as well, so here is an abridged list:

  • The channel selection menu for the graphs now stays open until you dismiss it.
  • You can now navigate the graphs with the keyboard. The mouse moves the cursor like normal, but you can now also move the cursor by pressing ← or →, and you can zoom in or out with ↑ and ↓.
  • We made a major performance improvement of the graph, especially on Windows.
  • We added a special math channel for Speedway users, calculating wheel slip in a different way that works on a Speedway bike.
  • The “Current Values” window (usually at the top right) was using long channel names, wasting a lot of space. Now it uses short channel names.
  • In version 62, we added the possibility to flip the delta graph, but there was a bug that made all lap colors the same when you do that. This is now fixed.
  • We now limit the number of simultaneously open laps to 30. 30 is enough squiggly lines to get confused anyways.
  • The “Add Runs” dialog is now bigger by default, and saves its size between restarts.

Speed vs. Acceleration on the XY Plot

Comparing Speed with Acceleration on the XY graph gives you a simple way of checking whether a change to the engine settings had the desired effect.

We also made some changes specific to certain lap timers:

  • For the UniGo:
    • The steering wheel sensor on the UniBox now calibrates itself automatically.
    • Barometric pressure now imports correctly from the UniGo 8005.
  • For the ALFANO:
    • The steering wheel and pedal sensors on ALFANO now import under the correct channel names. Also, the units for the lambda sensor are now correct.
    • OCD can now import ALF files from VisualData2 or the ALFANO Android app.
    • The track map now shows up correctly no matter the hemisphere you drive in.

As always, you can get the new version from the downloads page, or simply restart your old version of Off Camber Data. If you would like to contribute, and especially if you have some thoughts on additions to the X/Y plots, feel free to just comment on the blog, or send us an email at!
