Racepak and AEM Join For Dyno-Shaft

AEM Electronics has partnered with Racepak to make a V-net friendly Dyno-Shaft application that will allow Racepak users to measure their vehicle’s horsepower on the fly

Want to know what is going on exactly with your car via video while checking your datalogs?  Did you get out of the groove, spin the tires slightly, get on the wheelie bars, etc? Well now you can know with Racepak’s DataLink Software! Want brag with your friends or need tuning advice?  Racepak will soon have an option that allows you to upload your video log directly to Facebook.

This system allows the use of a remote or onboard camera to capture video and incorporate it right alongside your other recorded data. The high speed video provides images beyond those visible to the human eye, and as already led to some exciting and unexpected discoveries.

Simply import your solid state video cards with Racepak’s software and sync the 0 time of the video’s start point with the start point of your log and the DataLink does the rest.  Watch the videos as a small window as you look at the expanded datalogs, or switch to video view and overlay a wide variety of graphical data, including a Racepak dash!

DataLink Technical Information:

Graphs: With the DataLink graphs you can quickly see what your car is doing. Clicking on a channel button allows you to illuminate the graph line for that respective function, and you can illuminate as many functions at once as you desire. The different colors of each graph line help you identify each function at a glance. Graphs can be expanded or compressed, or you can zoom in for a full screen view on any area of interest.

Numeric Values: When moving the vertical cursor bar across the graph the numeric values of each monitored function, at the cursor’s position, will be displayed alongside its channel button. These values are present whether the channel’s graph line is displayed or not.

Timeline: DataLink relates all functions to a timeline. This permits you to pinpoint exactly when an event took place. Each program version lets you establish a ‘zero’ or ‘start’ point for the timeline. For example, this zero point might be opening of the throttle, the first revolution of the driveshaft, or some other identifiable event. The graph screen contains a small window that displays the time, to the 1/1000th of a second, from the zero point to the cursor location. Simply place the cursor on any event you see, and you’ll instantly know when it occurred.

Overlay Files: All DataLink programs, except File Viewer, have the ability to overlay the graphs from multiple files. This gives you the ability to quickly compare any recording against another. Diagnosing the results of tuning changes or driving techniques becomes instantly obvious.
