Performance mode is used to measure the acceleration and braking performance of your vehicle. Press the MODE button to scroll to the Performance Mode screen. This mode is divided into six screens, each of which displays different performance data. Navigate between these screens by using the▲▼buttons. Each screen will automatically display the results as they happen, e.g. if you drive from 0 Mph to 60 Mph then the 0-60 section will show the time taken.
Below is a list of the available Performance Mode display screens.
This Acceleration Screen displays a live velocity in the left half and in the right it shows the times of the following preset test ranges. 0 to 60, 0-100 and 0-100-0.
It also shows the maximum speed.

- Install PerformanceBox / DriftBox into your vehicle as described in the ‘Quick Start Guide’ section of this manual.
- Press the MENU button to select the Performance Mode.
- Now use the ▲▼ buttons to scroll to the ACCEL screen. This screen shows 0-60 in the top right hand corner:
- The left hand side of the screen shows your live velocity unless you are in an area of poor satellite reception in which case it flashes an image of a satellite.
- Now perform your 0-60 acceleration run. As your vehicle goes over 60 mph the time will instantly show in the 0-60 section of the window.
- If you come to a stop you will see that this time remains on view. The Vmax section will also show the highest speed you attained during this particular run.
- You can now instantly start another 0-60 acceleration, as you pull away the screen will reset and show your new values as you cross 60 mph.
- After doing a number of runs you can view your best 0-60 time by scrolling to the BEST screen.
- If you have your SD card inserted then your run data will be stored.
Please note, to record a results file, you must accelerate over at least 30 Km/H.
You can configure the minimum and maximum speeds of two of the acceleration ranges, the 0-100-0 range, the deceleration ranges, and one of the distance ranges, to give an array of useful tests.
If you wish to change the speed range over which performance is measured, press the MENU button from any of the performance mode screens and select the range you wish to change from the ‘Performance Menu’ and press OK.
- Highlight ‘ACCEL RANGE 1’ and press OK
- The following screen will appear with the start speed of ACCEL RANGE 1 highlighted:
- Whilst the START speed is highlighted use the ▲▼ buttons to change the speed.
- Press OK and repeat this procedure for the END speed:
The PerformanceBox / DriftBox normally takes the start of a performance run at the point at which the vehicle moves, but at drag strips the vehicle starts 1 foot behind the timing start line. You can make the PerformanceBox / DriftBox start all timing runs from 1 foot by enabling this feature.
- Press the MENU button to enter the Performance Menu.
- Highlight the 1 FOOT ROLLOUT option and press OK.
If an SD card has been inserted and the ‘Write Results File’ option has been enabled, the PerformanceBox / DriftBox will create two results files on the card. The first file, ‘RESULTXX.TXT’ gives the results for every performance test which has been completed, each time appending the data onto the end of the file. The second file, ‘BESTXX.TXT’, displays only the best results achieved for each type of test, overwriting previous results when required. If the unit is power-cycled, two new files will be created with an incremented file name and all data will be written to the new files instead.
Results text files are only created on the SD card if the ‘Write Results File’ option has been chosen from the Performance Mode Menu:
Note: No results will be written to the files if the speed does not exceed 50km/h during the tests.
The Speed Buzzer can be used in such tests as 0-100-0, as an audible warning when a certain speed has been reached. This means that during such testing the driver will not need to watch the display and can listen for the buzzer instead.
To change the speed at which the buzzer will sound, enter the MENU from any mode, scroll to Setup and click OK. The speed buzzer is one of the options in the Setup menu. Pressing either the ▲▼ alters the speed setting.
The speed buzzer will only sound once when the set speed is reached. It will not continue to activate every time the vehicle passes through the set speed, on acceleration or deceleration. In order to arm the speed buzzer once more the vehicle must either come to a complete halt for five seconds, or PerformanceBox / DriftBox must be power-cycled.
