Our affordable DataMite III USB can record what your car is doing out on the track.  This is our 3rd generation of DataMite data logger, and it has several advanced features vehicle data logging.  With its surface mount technology, we’ve been able to pack lots of power into a very small package.  It’s only 4.2 x 5.6 x 1.7 inches (mounting flanges and hardware make the “footprint” larger) and weights less than 1 lb.  It’s main features include:  

  • DataMite III USB with 3 RPM channels and 12 analog channels.

  • 3 axis accelerometer

  • USB communications cable for setting up and troubleshooting

  • 1 Gig (1000 meg) or optional 2 Gig SD memory card, provides hours of recording time and incredibly fast uploading to your computer for analysis.

  • Lighted Start/Stop logging switch

  • GPS enabled for optional DT3-GPS allowing for GPS track mapping and lap timing.

  • 50 or 100 Hz sampling rate

 The GPS feature is truly powerful, providing very accurate track maps, letting you compare the line taken on different laps.  


Here's a typical Graph screen with various Analysis features.

The DataMite software has features to make it easy for beginners, like the ability to automatically break up the data into laps (even without a beacon). This makes it easy for you to make comparisons of different laps, to see what makes you fast and slow.

The DataMite software has sophisticated features not found in software costing much more, like:

  • Graphing features of time aligning, zooming, cursor (to pin-point points on the graph), analyze (find the max, min, average and time or distance between 2 cursors), graphing vs RPM, time or distance, and much.

  • Log Book for recording all the other information of the run, weather conditions, suspension settings, engine settings, and much more.

  • Ability to link to our Suspension Analyzer program so you can actually watch the suspension move based on shock and steering travel indicators.

  • History log for tracking and sorting recent runs in chronological order.

  • Search features for finding past tests based on key words or settings of certain specs.

  • Ability to build custom reports.

  • Reading our electronic weather station.

Some features are only available in Pro version.

The software comes in either Basic or Pro versions, and has several features, including:

Basic Version:

  • Capability to configure and calibrate the software for most any combination of sensors.

  • Capability to tailor the program to work with most any type of vehicle.

  • User friendly, Windows interface, compatible with 95, 98, Me, XP, 2000 and NT.

  • Can print results using most any Windows compatible printer, many times in color.

  • Save nearly unlimited number of tests for recall, comparison and analysis in the future.

  • Allows several reporting and graphing options for analysis, either vs RPM or vs time in seconds.

  • Real time display of selected channels.

Added Features for Pro Version:

  • You get a complete detailed log book of all those other things required for a complete record of the run, like weather, suspension settings, engine settings (including a jet selector for weather changes), corner and cross weights, tire/shock/spring settings, user definable records, and much more.

  • Customize printed reports and especially graphs. You can include comments for each engine graphed.

  • User definable lap time summary reports.

  • Track mapping/friction circle analysis available on graph screen to give further insight to your analysis.  You can even play back a lap for continuous, "real time" analysis.

  • Write ASCII files for importing data into other computer programs.

  • Filter (find) past tests based on certain criteria, like 60 ft time, certain Track name, etc.

  • Overlay graphs for more than 2 runs (up to 6 runs).

  • Time align graphs (shift one graph left or right over another graph) vs time for better comparisons.

  • "History Log", keeps a running log of tests you have recently started new, run, graphed or reported.

  • "Analyze" button for graphs, let you use to cursor lines to "analyze" (average, max and min) what’s between the 2 cursors.

  • Send Shock Travel, steering, track mapping and more data to our "Full Vehicle" version of Suspension Analyzer for suspension animation and analysis.

  • Make Comparison Reports (side-by-side columns of numbers) for 2 or more tests.

  • Make Engine RPM Histogram graphs or overlay graphs.

  • Manually set the graph scales and save these scale settings for easy recall for various types of graphs.

  • More gauges and bar graphs on the Current Readings screen, which is very useful for debugging and initial system setup.

  • Lap Segment determination and editting and Lap Segment Time Analysis.

  • Lap Summary analysis with Correlation determination via reports and graphs.

New DataMite 4/DataMite Analyzer v4.1 Features:

The DataMite 4 has 2 digital output channels, which the DataMite Analyzer v4.1 software lets you take advantage of.  

  • Turn on or off various devices via relays at certain conditions, like a fan when a temperature goes above a certain limit.
  • Shift light at a particular RPM
  • Engine rev limiter
  • Engine over speed cutoff
  • Low oil pressure engine cutoff
  • And most any other logic you can imagine

This screen shows how you can set up a digital output channel
