Lap Timing
Displaying your Lap times as you drive around a circuit is simple with PerformanceBox. You can
display your last and best Lap times and Lap count, and also display split times for up to six
specified split points around the lap. The split files can be saved and reused should you attend the
same circuit again, guaranteeing consistent data. You will be able to catalogue and review your
performance over any given period of time.
Through the PerformanceBox website and forum you are able to download circuit overlays from
around the world, compare lap times, and share lap overlay data with other users.
Speed Display
PerformanceBox has a display screen mode that shows a large digital speed value and compass.
In open conditions, PerformanceBox has a velocity accuracy of 0.1km/h, which is useful for
checking the accuracy of your vehicle’s speedometer.
In this mode there are also Odometer and Height display screens.

Power Calculations
PerformanceBox can help you to measure the power developed by your car’s engine, either at the
wheels or flywheel. Having set the vehicle weight, results are calculated from the measurements
taken by the fast GPS engine to give you useful guidelines to the car’s brake horsepower or
kilowatt output. Because these calculations are made from the GPS data rather than
accelerometers, your results are likely to be more consistent and accurate.
Data Logger
For drivers keen to improve their lap times and get valuable feedback on technique,
PerformanceBox includes a sophisticated, fully functioning data logging package. If used with a
64mb SD card, PerformanceBox can log up to 50 hours of continuous data, which can be analysed
in great detail in the available software.
This software allows graphical analysis of acceleration, braking, cornering and lap times, and if the
PerformanceBox is used in conjunction with a Micro Input Module, data from the vehicle itself
(such as RPM and throttle angle) is recorded alongside the GPS parameters.
You can overlay up to four files, and you get an accurate track map to compare your driving line
between different laps. The software also features a graph measure tool, allowing for precise
analysis of performance figures. Data-logging capabilities are further enhanced by automatically
generated text data on the SD card.

Satellite Reception
PerformanceBox calculates all of its logged data from the information it receives from GPS
satellites and relies on being able to get a good lock to produce this data. So it is imperative that
PerformanceBox (or optional external antenna) is placed in the best possible position for a clear
view of the sky.
If you are using an external antenna, ensure that it is connected before you power up
PerformanceBox.
The location that you drive in can also affect data quality, if you drive in a very built up area or an
area with overhanging trees then the signal quality can degrade. If the satellite reception does drop
out in use, you will see either of the following symbols:
1.
2.
3.
Searching for satellites at power up
Whilst the PerformanceBox is acquiring satellites it will flash the image of a satellite, the location of
the flashing image depends on the screen you are in.

Performance Mode
The 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.

results for every performance test made using the PerformanceBox, 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:

Speed Buzzer
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 must be power-cycled.
Event Marking
Pressing the OK button when in any of the Performance Mode screens will create an event mark in
the logged file (see ‘Event Marking’ in the software section.)

Racelogic Ltd Lap Timing Mode
02/05/2014 Page 18
Laptiming Mode
PerformanceBox can be used to measure lap times by storing the position of a virtual gate and
using this to trigger the start and end of a lap. Further locations can be added to represent split and
dedicated finish lines.
Start/Finish Line: Defines the point at which one lap ends and another starts. It also
defines the start of a test that ends in a different location, such as a sprint or slalom stage.
Split Line: Defines a point on the track or stage at which intermediate time and speed
measurements are displayed.
Finish Line: Used only in point-to-point tests (such as sprint or slalom tests), to mark a
finish point that is in a different location to the start point.
Measuring Lap times
There are two ways of measuring lap times as you drive round a circuit: by setting the start/finish
and split points through the PerformanceBox menu screens, or by using the ‘Simple Lap Timing’
option. The latter is useful if the user is in a situation where several button presses are difficult to
achieve, such as during a qualifying run.
Simple Lap Timing
This method of lap timing requires just one button push to set up a start/finish line. With the
PerformanceBox in Lap Timing mode, press either the up or down arrow key as you drive over the
desired start/finish point. The screen will then display the following message:
The screen will then count down to 0 and revert to the normal lap timing screen:
If an arrow button has been pressed in error this count down allows you to abort the setting of the
start finish line, whereupon the lap times will be calculated according to any previous start/finish
points that may have been set.
As soon as the start / finish line is crossed again, lap timing will begin. The lap time will be
displayed at the end of the second lap along with the current best time in the top right and the lap
count in the top left of the screen.

Racelogic Ltd Lap Timing Mode
02/05/2014 Page 19
Lap Count
A count of the number of completed Laps is displayed in the top left corner of the Lap timing
screen.
To reset the Lap count and the Best Lap time, press the RESET button.
Lap Timing Including Split Points
This method allows for the setting of a start/finish line, up to six split points, and a separate finish
line if the course being driven is of a sprint or hill-climb type. Due to the fact that it requires several
button pushes it is best employed in a non-race session.
Firstly set the start/finish line and splits or load a previously saved set from the SD card
(see Setting Start/finish and Split Lines below).
If you want to save your lap times to a file, insert an SD card.
Drive around the circuit, your times will automatically appear on the PerformanceBox
display:
Big Speed @ Split display
There is a choice of what is displayed in the main area of the Lap timing screen, either your
Lap/Split time, as shown above, or the Vehicle speed as it crosses a split point or start/finish line;
with the current lap in the upper left and the split time in the upper right of the window:
If Split points are placed at the exit of corners then this mode displays the corner exit speed, which
is a very easy way to help you improve your speed out of a particular corner. To display the exit
speed at the last split instead of the time press the MENU button and change the ‘BIG SPEED @
SPLIT’ option.

Split to Split time
There are two different ways of measuring split times. The default is from the start of the lap to the
split, the other method is from one split to another. To change between these options, tick or un-
tick the option ‘SPLIT TO SPLIT TIME’ in the LAPTIMING MENU.
Split Widths
When setting a start / finish or split line, PerformanceBox will set the width of the line at a default
value of 25m (12.5m either side of the point at which the OK button was pressed.) However this
can be changed by selecting the Split Widths function and altering the value using the ▲▼ buttons.
This feature is useful if PerformanceBox is being used on a track where separate sections pass
closely by each other, and eliminates the possibility of going through a split line in the wrong
direction.
Clearing your Best Lap time
Press and hold the RESET button for 1.5s.
One Shot Mode
By default, PerformanceBox starts the lap time from a start / finish line. If you want to start the lap
time from the moment you start moving, then you need to select ‘One Shot Mode’. To set this
mode:
Press the MENU button to enter the LAP TIMING menu.
Highlight ‘ONE SHOT MODE’ and press OK to activate.
Bring the car to a halt at the start point (previously set using either set start/finish method.)
After two seconds the following screen will appear:
