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 119: The boring release


Not all releases bring exciting new features, but it’s often the boring ones that have just the fix you need. Version 119 is one of those.

For ALFANO users, the most important change is the new channel mappings for the extension box. If you are still missing some channels, please let us know! We also fixed a smaller issue to do with driver and track names getting read out wrong.

We also improved the behavior of the program in cases where the GPS signal is poor. We cannot make a precise signal from a distorted one, but we can handle the situation much better, and that’s what we did.

Finally, there are a number of fixes for the Track Attack edition of Off Camber Data:

  • We found and fixed several problems with the VBO file format. This should affect users of Harry’s Lap Timer and Porsche Track Precision.
  • We also added support for the RaceChrono lap timer software.
  • Users of the latest version of CMS Lap Timer now get better support.
  • For the sim racers, Assetto Corsa import now imports gear and acceleration channels correctly.
  • Finally, some users of the RaceCapture system reported problems when they were stationary in the pits for a long time. Those problems have now been fixed.

You can get this new version from our download page at, at, or simply restart your version of Off Camber Data. If you have a suggestion, feedback, or just want to say hello, drop us a line at, or find us on Facebook at
