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.
|Acceleration 2 screen shows the 30-50 and 50-70 times. However these two test ranges are user adjustable through the setup menu. Peak lateral g (cornering force) is also shown along with an average velocity value.|
|The next screen shows the times required to reach various speeds from rest. The target speeds are every 10 km/h or mph (depending on the units selected), up to a speed of 100 km/h / mph.|
|This screen continues the readings of the previous screen, listing the speeds from 110 to 200 km/h / mph.|
This screen shows the best results of the two test ranges from each of the acceleration screens.
|This screen shows the time and distance of two user adjustable deceleration ranges. These test ranges can be configured in the setup menu.|
|This screen shows the same information as the previous Deceleration screen, but for a different user-defined speed range.|
|This screen shows the time and end velocity of two user-configurable distances, i.e. 0-100m. If the units are changed to feet then the two test ranges default to 60’ and 330’, but can be changed to the desired distance. Start Speed is also configurable.|
|This screen shows the time and end velocity of two user-configurable distances, i.e. 0-400m. If the units are changed to feet then the two test ranges default to 660’ and 1320’, but can be changed to the desired distance. Start Speed is also configurable.|
|This screen shows the current acceleration and peak acceleration achieved by VBOXMini. A level bar at the bottom of the screen also shows this information in graphical form. The MAX value is cleared by pressing the RESET button.|
|This screen shows the current deceleration and peak deceleration achieved by VBOXMini. A level bar at the bottom of the screen also shows this information in graphical form. The MAX value is cleared by pressing the RESET button.|
|This screen shows the current lateral acceleration and peak lateral acceleration achieved by the VBOXMini. A level bar at the bottom of the screen also shows this information in graphical form. The MAX value is cleared by pressing the RESET button.|
Measuring the 0-60 time of your vehicle
- Install the VBOXMini into your vehicle as described here.
- 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.
Editing a Performance mode Test Range
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
|WRITE RESULTS FILE|
|ACCEL RANGE 1|
|ACCEL RANGE 2|
|0 - 100 - 0 RANGE|
Example: Editing ACCEL RANGE 1
- 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:
1 Foot Rollout
The VBOXMini 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 VBOXMini start all timing runs from 1 foot by enabling this feature.
Enabling 1 Foot Rollout correction
- Press the MENU button to enter the Performance Menu.
- Highlight the 1 FOOT ROLLOUT option and press OK.
Results and Best Files
If an SD card has been inserted and the ‘Write Results File’ option has been enabled, the VBOXMini 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:
|✓ WRITE RESULTS FILE|
|ACCEL RANGE 1|
|ACCEL RANGE 2|
|0 - 100 - 0 RANGE|
Note: No results will be written to the files if the speed does not exceed 50 km/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 the VBOXMini must be power-cycled.
