Speed Profiler App
The Speed Profiler Application is ideal for measuring durability and fuel economy and for tyre testing. You can set a target speed for a duration of time or distance in the Speed Profile Software on your computer. This will generate an .spp file. Once you have installed the Speed Profiler App, you can load this file onto the Performance Box Touch with an SD card. The driver will then receive both audible and visual alerts if they deviate from the target speed (or tolerance). You can download the app here, and find the instructions for how to install it here. |

Getting Started
When the unit is powered up, it will search for a speed profile file (.spp) on the inserted SD card. If only one file is present, this file will be loaded automatically. If multiple files are present, the unit will display a speed profile selection menu where you can choose the profile you want to use. The speed units used in the .spp file will be detected, and Performance Box Touch will update to match. |

Speed Profile Display
The application includes a live graph which allows the driver to see forthcoming speed changes and helps to keep their speed within tolerance. The graph scrolls from left to right, plotting GPS speed against time. The current speed is indicated by a white square which remains static, with a white trace behind displaying the speed history. |
![]() |
The X-axis (speed=0) is identified by the blue line. The target speed is identified by the red line. The speed tolerance margin is identified by white lines on either side of the target speed. The display shows the last 2.5 seconds and the next 6.5 seconds of the configured profile. |
Start/Reset
Clicking on the START button will start the speed profile file (.spp). If you selected Wait Until Moving in the Test Settings, the test will not start until the unit detects movement. Once started, you can press the RESET button to terminate the test and stop the logging (if applicable). If you reset the test before the end of it, the unit will not save a score to the _results.txt file and 'RESET' will be displayed next to the test in the SCORE field. |
Pause/Resume
When the vehicle is stationary, you can pause the test using the Pause button. | ![]() |
You can resume the test by pressing the Resume button. | ![]() |
Current Speed Chart
The current speed is indicated by a white square, with a white trace behind displaying the speed history for the last 2.5 seconds. The current speed will be always centred vertically on the screen. |
Target Speed Chart
The target speed is identified by the red line. The chart shows the target speed for the last 2.5 seconds and the next 6.5 seconds of the configured profile. |
Speed Tolerance Margin
As it is difficult to drive at precisely the expected target speed, the speed tolerance provides a margin on either side of the target speed with which the driver can keep within without affecting the test results. The speed tolerance margin is identified by white lines on either side of the target speed and can be defined in the Test Settings.

Current Speed
Displays the current speed of the vehicle using units defined in the .spp file. |
Target Speed
Displays the target speed of the vehicle using units defined in the .spp file. It will change to the next value 3 seconds before the end of an accel/decel transition. If the change is a deceleration, the value will have a red border, If the change is an acceleration, the border will be green. 'Lead-in' beeps will also sound 3 seconds before the end of a transition to draw driver attention to an approaching change in speed. You can define the beep volume in the Test Settings. |
Progress
This displays the progress of the test as a percentage. |
Nightmode
If you enable Nightmode in the Test Settings, tapping a free space on the screen will toggle between the default display profile and a Defined Profile for night-time operation. | |
The Nightmode display is indicated by a Moon Icon in the upper right-hand corner. | ![]() |
LEDs
The 4 LEDs at the top of the unit provide visual feedback in relation to the target speed: | ||
Current speed is <2 (km/h or mph) faster/slower than the target speed |
LEDs will be off |
|
Current speed is 2 – 2.5 (km/h or mph) faster/slower than the target speed |
1 LED will be green if slower |
1 LED will be red if faster |
Current speed is 2.5 – 3 (km/h or mph) faster/slower than the target speed |
2 LEDs will be green if slower |
2 LEDs will be red if faster |
Current speed is 3 – 3.5 (km/h or mph) faster/slower than the target speed |
3 LEDs will be green if slower |
3 LEDs will be red if faster |
Current speed is >3.5 (km/h or mph) faster/slower than the target speed |
4 LEDs will be green if slower |
4 LEDs will be red if faster |
Satellite Status
SD Status
The SD Card Icon displays the status of the recording media. When the unit detects an SD card with free space, the icon will be green. Pressing the icon when it is green will manually start or stop the data logging. |

End of Test
At the end of a test, you will see a results screen. If a driver had been previously selected, you will see a score associated to that driver which represents the % of test time inside the tolerance margin. You can also assign the result to another driver by selecting the New Driver button. |
Results screen |
Save the score to the '_results.txt' file on the SD card by pressing the Save button. To exit without saving, press the Cancel button.

Test Settings
This menu contains settings for Beep, Speed tolerance, Nightmode, Speed profile file (.spp) and Driver options. |

Wait Until Moving
This setting will start the test once the unit detects that the vehicle has started moving (faster than 0.8 km/h). This is only valid if the loaded speed profile file (.spp) begins with an acceleration. If you select Automatic Logging on the General Settings screen, the logging will start once movement is detected. |
Beeps
This setting controls the volume of the audible 'lead-in' beeps during accel/decel transitions. You can manually adjust the beeps between 5 volume levels, 1 is the quietest and 5 is the loudest. You can also turn the beeps off. |
Speed Tolerance
This setting controls the tolerance of the test in relation to the actual speed, compared to the speed profile detailed in the loaded speed profile file (.spp). Available range is between 1 to 10 (km/h or mph dependent on the Speed Units set in the General Settings). |
Nightmode
In this mode you can press on the Main Screen to quickly toggle between the default display profile and a profile that suits nighttime operation. You can set the nightmode screen and LED brightness profile on the General Settings screen. |
SPP Selected
This area displays the currently selected speed profile file (.spp) that was chosen during startup. To change the profile, press the New SPP button, which will open the Select Speed Profile menu. |
