02 - VBOX LapTimer - GPS
Obtaining the best GPS quality
Placement of the GPS antenna is crucial to the quality of the data recorded by VBOX LapTimer. Any metal close to a
GPS antenna can disturb the signal in an unpredictable way due to interference from reflections of weak GPS signals.
For the best results, use the antenna in the centre of a metal roof away from any roof bars or radio antennas. Do not
mount the antenna close to the edge of the roof as reflections from the ground may interfere with the signals. Avoid the
edges as reflections from the A-pillars will cause problems.
Mount the antenna as high up as possible and keep above any roll bars. Pieces of metal close to and above an antenna
will badly disrupt the GPS signal.
https://racelogic.support/02VBOX_Motorsport/VBOX_LapTimer/VBOX_LapTimer_-_User_Manual/
8
Page 9
If the vehicle being used does not have a metal roof, then place the GPS antenna on a flat piece of metal at least 10cm
in diameter. If this is not possible, copper or aluminium foil can be used to create a shaped ground plane underneath the
antenna. For example, on a fibreglass roof, mount the antenna on top of the roof, and place some adhesive backed
metal foil underneath, on the inside of the roof.
Acquiring Satellite Lock
Tall buildings or trees can block GPS signals, causing a reduction in the number and quality of satellites being tracked,
leading to inaccurate position measurements and a noisy velocity signal.
GPS works best in open areas/ Avoid tree lined roads
GPS Coldstart
If VBOX LapTimer is struggling to acquire satellite lock, a GPS coldstart may be required. This may be necessary when
the unit hasn’t been used for a number of days or has dramatically moved location since its last use. To perform a cold-
start, select MENU > GPS OPTIONS > COLDSTART.
Note: The GPS Options menu cannot be accessed when the LapTimer is being used in OLED mode. In this instance,
the coldstart must be done on the connected unit.

Page 14
05 - VBOX LapTimer - Predictive Lap Timing
For this mode to work, a start/finish line is required. Make sure that a track layout is selected through the main menu, or
set a start line manually.
• Until the start line is crossed, the screen will show
‘Waiting for start line’ and the distance from current
location to this point.
• When the line is first crossed and during the first
lap, VBOX LapTimer will create a reference lap.
• The second crossover of the start line will allow
VBOX LapTimer to start predicting.
• The reference lap will be replaced with any
subsequent quicker lap time.
• To fix this comparison lap time at any point, press
the square button.
• Fixing a reference lap prevents any faster lap time
from replacing it.
• Power cycling the unit, clearing laptiming data or resetting the start/finish will remove the fixed
reference lap. If you wish to retain a fixed reference
lap, please ensure the lap is saved to the SD card.
This can then be loaded to the unit if required.
https://racelogic.support/02VBOX_Motorsport/VBOX_LapTimer/VBOX_LapTimer_-_User_Manual/

Page 15
• Pressing and holding the square button for 4
seconds when in this mode will clear the stored
reference lap.
Delta-V LEDs
The two front panel LEDs are used in predictive lap timing mode. They indicate if the current vehicle speed is faster or
slower than the speed was at the same position in the reference file.
The LEDs will show RED if the current speed is slower than the reference, or GREEN if the current speed is faster.
The value defined within the ‘Delta-V range’ setting dictates the min and max speed values to full brightness.
The left LED represents 0-100% of the positive or negative range and will illuminate first.
The right LED represents 50-100% of the positive or negative range and illuminates second.
Combo G LEDs
While the screen still displays the Delta-T for each lap, the user has an optional mode which takes over the function of
the LEDs in the predictive lap-timing screen.
If the Combo G is greater than a selected minimum threshold (50 % LED minimum %, 0.5 g default), the LEDs will light
up various colours dependent on the maximum g threshold selected (1.0 g default).
• The LEDs will show RED where the Combo G has reached the LED minimum % selected (i.e. 50% by default).
• Above this minimum Combo G selected, the LEDs will show a colour gradient between RED and GREEN, giving a
changing YELLOW/ORANGE colour, dependent on the live Combo G.
• The LEDs will show GREEN where the Combo G is equal to or greater than the maximum g threshold selected.

Default settings example:
Save reference lap
This feature allows the user to save a reference lap for future use, insert an SD card into VBOX LapTimer and use the
menu options shown below. Note that the vehicle must be stationary to make this transfer.
Once this is selected, the following messages show saving has been successful. This will be stored on the SD card as
LAP.REF in the ‘Data’ folder.
Load reference lap
To load a reference lap file stored from a previous session, put the desired file onto an SD card and load the card into
VBOX LapTimer. The file can have any name, however it must be saved in the Data folder and only one .REF file should
be present. Select the menu options as shown above – but select LOAD REF LAP instead of SAVE. Note that the
vehicle must be stationary to make this transfer. Reference laps will be reset when either a new start/finish is set, or if
the ‘reset lap timing data’ option is selected from the lap timing menu within main menu.
Live timing
The main predictive screen shows a continuously updated bar graph with the +/ - to previous. When a lap is completed,
it will give a final lap time and total time difference to reference lap. If a faster time is achieved than the reference, a
negative time will be shown.
https://racelogic.support/02VBOX_Motorsport/VBOX_LapTimer/VBOX_LapTimer_-_User_Manual/

associated with poor GPS reception.
Pressing the square key with this option highlighted will cycle through the following modes:
GPS+GLONASS - LapTimer will use the standard GPS satellites as well as the Russian GPS GLONASS
satellites.
GPS+SBAS - LapTimer will use a Sateliite Based Augmentation System, e.g. WAAS or EGNOS, to improve GPS
data.
GPS+BeiDou - LapTimer will use the standard GPS satellites as well as the Chinese BeiDou Navigation System.
The default setting is GPS+GLONASS.
Leap seconds
The number of leap seconds here sets the current offset between GPS and UTC time. This is set by official bodies to
compensate for the slowing of the rotation of the earth. A new leap second is usually introduced every 4 to 7 years. The
last leap second was added in December 2016. The current offset is 18 seconds - click here for more details.
