Off Camber Data Overview

This is the most common way of using Off Camber Data. We’re comparing two laps from one session, which are shown on the left. We’re comparing the speed of two laps from these runs, with a delta graph below that shows where time was gained and lost. A track map helps us orient ourselves, and the video in the top right corner shows what was happening at a specific moment. This is especially helpful with young drivers!

A simplified configuration of OCD

You can disable various parts of the UI so you can concentrate on the graphs alone. The slip graph in this screenshot is a calculated channel that shows either clutch slippage, a lock-up, or too much power. To analyze this in detail, you can select a range and zoom in.

Channel Management

This dialog configures your channels. The most useful thing here is renaming them.

OCD's Histogram View

The histogram view works for any channel, but it is most useful to see how much time you’re spending in which RPM range. You can use this information to optimize your gearing. To get the most meaningful results, you can create a histogram only for the times when the driver is accelerating.

Driver Management

In Driver Management, you can get some information for each driver in your team. You can also give them a unique flag or icon to identify them quickly in the UI, or just because it’s fun.

White background in graphs and maps

For printing, or maybe just because you prefer it, you can turn the background white. You can also turn on grid lines, if that’s your style.

Split Time Window

This is the Split Time Analysis view. It shows all laps from each run, and calculates best rolling and best theoretical lap. It also calculates the range for your non-hidden laps, so that you can quickly pinpoint where you are inconsistent.

Min/max table for selected channels

This table shows minimal and maximal channel values for the selected runs. It’s most useful for the mechanic, who wants to see top speed, top RPM, and top temperatures, but you can also use it to analyze minimum corner speed, average speed around a lap, and more.

OCD's import window

This is the import window while importing a new run from the lap timer. You can correct the values from the lap timer, add notes and tags, or align a video with the data.

OCD's video alignment window

In this dialog, you can align a video with the data, in case they don’t start at exactly the same time.

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!
