The DataMite III or DataMite 4 USB Loggers are used by several tractor pullers. The USB DataMite has features for the recording vehicle speed and distance traveled using a GPS sensor. Then a special Run Type called "Auto Cross (non lap)" where the Road Race/Circle Track DataMite software does not expect repetitive laps. A straight line run like a tractor pull is a "non lap" run where the beginning and end of a "lap" are not at the same point.
The DataMite III has 3 RPM channels, the DataMite 4 has 4. Here's 4 RPMs recorded (engine, driveshaft, and left and right rear tires) and graphed vs distance traveled determined by the GPS sensor. The pink cursor lets you pin-point readings on the graph, as shown on the right side labels.
Using the GPS sensor to determine vehicle speed, here's a graph of wheel/tire slip and clutch slip graphed vs time, and then graphed vs distance.
