0-60, 0-100, 40-0, 60,0, 0-100-0, 60-80... What are we hinting at here? Many motoring enthusiasts will probably recognize these numbers as common testing benchmarks for all sorts of vehicles during acceleration and braking tests, usually on a flat straight line.
Something as simple as a 0-60 (MPH) sprint can be calculated on many GPS-based devices today, but the same method can be applied to testing a wide range of data within DigSpice's Driving Analysis Software. With the DigSpice II GPS Logger and the Driving Analysis Software, you will be able to extract all sorts of data, such as sprints (ex. 0-60), braking (60-0), slalom, top speed, and more.
While many lap timers or applications will require you to use certain modes to record your acceleration times, this same data can be extracted from the Driving Analysis Software at any time during playback, without having to worry about using predetermined routes, stopwatches, settings, etc.
How does this work? Simply record you data as you would with any run with the DigSpice II GPS Data-Logger. You will save your raw data as you normally would, but take note of which session you wanted to extract your acceleration data from if you have a mix of lap times and acceleration tests mixed within your data.
Basic steps:
1) Make sure to place the DigSpiceII GPS receiver in clear view of the sky. Best results when placed in the upper front windshield (unobstructed), or affixed to the outside on the top of the vehicle using the included enclosed outdoor case or gaffer's tape (or similar) as shown:

It is highly recommended to set the GPS receiver to 10Hz within the Driving Analysis Software to ensure accurate data recording within 100 ms. Also recommended to set recording trigger speed to the minimum to record all movements
2) When first extracting your GPS raw data from the DigSpice II unit, manually set your regions in which you wish to record your acceleration or braking times. Since we have recorded data in a straight line, we have set up Start/Finish sections as shown below (similarly, this can also be done using standard circuit control line data using just sectors instead with a start/finish line).

For raw data sets containing multiple overlapping or indistinguishable lines, it will help to check the box labeled "Show stop position" to help identify where runs start and stop.
2) In the next screen you will see your data presented in both mapped location and as a graph/chart above. Since we are looking to examine acceleration times, we want to jump to the first section of the data right on the graph where we can see the vehicle accelerating from a stop. Since we are determining 0-60MPH times, we want to set the first sector right where the GPS logger registers movement at the beginning of the run. Set the second sector where you wish to record the elapsed time (in this case, at 60MPH). Once a set of sectors has been placed, times will automatically be displayed on the same color line at the bottom of the screen (as outlined).

Again, besides target speed, sectors can also be set based on your own preference, such as how long it took reach 1/4 mile, how far a vehicle traveled in a set time limit, or what was the maximum speed in the given time/distance.
3) For multiple sets of data, you can set up additional sector points to compare consecutive runs, or a different test entirely (in this case the data shows 3 back to back 0-60 sprints on the same straight).

And that's it! We hope you find this how-to useful. DigSpice Driving Analysis software allows a quick and easy way to compare set of data and to save those sections for easy access for later use.
