1DL1 CLUB Introduction
The DL1 CLUB was previously known as the DL1 MK3, the two products are identical,
so any reference to DL1 MK3 equally applies to DL1 CLUB and vice versa.
1.1 What is the DL1 CLUB?
The DL1 CLUB is a completely updated version of the DL1. It is a state-of-the-art
vehicle data logging and control system. Put in the simplest terms, it stores a wide range
of vehicle data for later analysis on a computer - the system does not include an in-
vehicle display, Race Technology has a number of dashboard solutions available for the
DL1.
1.2 Who is the DL1 CLUB designed for?
The DL1 CLUB is designed for autosport applications including drag racers, single
seater racing cars, rally cars or road cars - however it is also ideal for use on power
boats, go karts and motorbikes. It is also an ideal platform for use in the auto industry
for car testing of all types, from long term monitoring to competitor benchmarking.
1.3 What does the DL1 CLUB do?
The DL1 CLUB can store data from a number of sources including its built in high
accuracy GPS and accelerometers, wheel speeds, shaft speeds, engine speeds,
temperatures, pressures, lap times, sector times etc. The DL1 comes packaged with the
excellent Race Technology data analysis package for Windows. The software allows
super accurate track mapping, user defined channels, powerful graphing and allows
direct comparison of up to 10 data sets (races) simultaneously with almost unlimited
laps. The DL1 CLUB can also be used to supply data to dashboard displays and to drive
auxiliary outputs to control fans, pumps, or lights.

1.4 Why use GPS?
One of the key features of the DL1 CLUB is its built in high accuracy GPS system - this
gives the DL1 advantages over other data loggers in 2 key areas - greatly improved
track maps and far more accurate speed data.
1.4.1 Track Mapping
Conventional data loggers require a "closed circuit" to enable them to calculate the track
map; the shape of the track is estimated from a combination of the lateral acceleration
and speed. This works adequately in some situations but it becomes increasingly
inaccurate for long tracks and impossible for open circuits, motorbikes or boats. In
contrast, the GPS will produce high accuracy track maps in almost any situation.
1.4.2 Speed Measurement
While speed is probably the most important parameter that anyone wants to measure
using the data logging system, it is also the most inaccurate in a "conventional" system.
The normal way to measure speed is to simply attach a pickup to a wheel to detect how
fast it is rotating - but the rolling circumference of a tyre changes by 4% just with wear
and temperature. Even worse, the error increases significantly under race conditions
where the tyre is under load - typically the tyre slips by up to 20% under hard braking
going into a corner. Measuring speed using GPS is now common practice in high-end
systems - under typical conditions speed error is well under 1%!
1.5 DL1 CLUB Features
The DL1 CLUB is an all-new, 3rd generation, data logger system from Race
Technology. It is a complete redesign of the DL1, retaining all the best features and
improving and adding where possible. Some of the most noteworthy features include:
•Built in GPS
The new GPS unit is based on our own high accuracy GPS3 technology and
calculates position and speed 5 times every second. This is easily the fastest, most
accurate GPS system available for under $1500. The measurements from the GPS
and accelerometers are combined to calculate very high accuracy positions and
speeds at 100 times a second. Optional storage of raw GPS data for post processing
at 20Hz is also possible.
•Built in accelerometers
Built in 3-axis accelerometer with 2g full scale (optional 6g full scale).
•Built in yaw gyro for slip angle measurement (optional)
•Logging to SD cards
Works with SD and SDHC, for up to 32GB storage.

•Up to 12 analogue inputs
The DL1 CLUB has 12 very high accuracy analogue inputs. All inputs have a
maximum of 25V input
•Up to 4 output drivers
Low side driver outputs are available for controlling pumps, fans, lights.
•2 RPM inputs
The DL1 CLUB has 2 RPM inputs, only one of which can be used at any one time.
One input is designed to be connected to "high level" sources, such as the ignition
coil. The other input is designed for low level signals such as a feed from the ECU.
•4 wheel/shaft speed inputs
The DL1 features 4 totally independent wheel/shaft speed inputs. These can be used
to measure the speed of all four wheels, or slip ratios across a torque converter for
example.
•Two RS232 ports
Either port can be used to receive data for logging, one port is always used for
outputting data for storage to a VIDEO4 or to a DASH display.
•CAN port
CAN port enable receiving and transmitting of messages at configurable rates up to
1Mbit/s
•Remote start/stop and add marker inputs
•Dual 5v reference outputs
Two independent 5v outputs can be used to drive up to 500mA each for sensor
outputs.
•Simple operation
A single button to start or stop logging, it's as simple as that! If the button is
inaccessible from the driver’s seat then a remote button and status indicator can be
added if required.
•Power supply requirements
The power supply to the DL1 CLUB data logger can be taken directly from the
vehicles 12v supply, or it can be powered from its own battery if required. The power
supply is smoothed and regulated within the DL1 CLUB ensuring its performance is
highly robust and stable.
•USB interface
USB connection for direct connection to a PC for configuration

•Testing
Very high reliability is ensured by calibrating, temperature testing and vibration
testing each unit on an individual basis. Autosport applications make tremendous
demands on electronic systems and we take great care to make sure our products are
up to the task. All the connections to the units are vibration proof, high strength to
ensure that connections do not fail at the critical time.

3Installing the unit
3.1 Mounting
As the DL1 CLUB contains accelerometers, it is important that the unit is mounted on a
flat, fairly level surface in the vehicle. A small amount of tilt can be compensated for in
the software; however, large tilt angles cause loss of resolution and increased noise due
to vertical vibration. For more instructions on compensating for accelerometer tilt, read
the following pag:.
http://www.race-technology.com/wiki/index.php/Technical/ZeroingAccelerometers
Just as importantly, the logger must be mounted "squarely" in the vehicle with the
button facing towards the back of the vehicle. If the unit is mounted at an angle to the
direction of travel for the vehicle, then the unit will be measuring longitudinal
accelerations when you are cornering and vice versa. Acceleration errors caused by
mounting the unit at an angle to the direction of travel cannot be compensated for, so it
is important to get it right.
In most installations the unit will be mounted using 2 strips of scotch lock tape on the
base of the unit. This is simple and secure and allows the unit to be moved quickly
between different vehicles. If a more permanent installation is required then there are
two main options available:
1. You can use either the mounting holes on the side of the unit. These are designed to
take 2.9mm self tapping screws (No. 4) with a maximum penetration depth of
6.5mm.
2. Or a set of "hook in" brackets are available that fit into the channels on the sides of
the case. They are made from brushed stainless steel, and are designed to be used
with M4 screws or similar diameter self tapping screws (#7 or #8). The mounting
diagram for these is shown below:

3.1.1 Bracket Mounting
3.2 Power
The DL1 CLUB Unit is supplied with a cigar lighter based power supply. The centre pin
connects to +12V and the outer connects to the vehicle ground. This method is
convenient if you are temporarily connecting the unit to the vehicle (typically on a road
car).
If you want to permanently wire the DL1 CLUB Unit directly into the engine wiring
loom, rather than using the cigarette lighter socket, then you must use a fused supply
with a fuse rating of no more than 1 amp. It is also highly recommended that the unit
has its own external power switch so it can be easily turned off. This is to prevent any
draining of the battery, or any damage to the unit when the engine is turned on or when
the car is being cranked over. It is recommended that you only turn the unit on once the
engine is running. It is possible that leaving the DL1 CLUB turned on during cranking
may corrupt the data in the logger.
Also please note that in all cases the GPS receiver is powered on whenever there is
power to the main unit - it does not turn on and off with the main unit, so if the DL1
CLUB is left connected to the battery it will flatten it.

Alternatively, the DL1 CLUB can be powered from a separate battery if required - this
is often appropriate for temporary installations where a cigar lighter is not available. The
DL1 CLUB requires a minimum of 10v and draw about 100mA-200mA, so the size of
the battery should be chosen to give sufficient run time. For example a 1Ah battery
would give about 5 hours operation. Because of the current supply requirements only
rechargeable batteries should be used, you cannot use disposable batteries. If you do
require a battery pack, Race Technology keeps a wide selection in stock - call us with
your requirements.
Start the vehicle, wait a few seconds then connect the power lead to the unit. After a few
seconds, the "Power" LED will come on and when the unit is ready to log the "status"
light will flash. Wait for a few minutes to enable the GPS to obtain a good positional
lock. Once the receiver has a lock, the GPS status light on the DL1 CLUB will start
flashing.

4Quick Start Guide
This short guide is intended as a quick introduction to enable you to install the DL1
CLUB in a vehicle and log your first set of data. It is certainly not intended as a full set
up guide. There are four sections to the quick start guide: Installing the DL1 CLUB into
the vehicle, Default configuration, Logging some sample data and Looking at the data
for the first time using the software.
4.1 Installing the DL1 CLUB in the vehicle
4.1.1 Mounting the DL1 CLUB in the vehicle
The DL1 CLUB should be mounted in the vehicle on a flat horizontal surface. For
temporary installation you can just use the Dual-LockTM tape supplied, or for a more
permanent installation the mounting brackets. The DL1 CLUB must be mounted with
the buttons and lights facing either directly towards the back or the front of the car.
Avoid any extremes of temperature and vibration for both the DL1 CLUB module and
the GPS antenna. In particular, if the DL1 CLUB is exposed to vibration then the GPS
data will become inaccurate.
4.1.2 Correct Mounting of the GPS Antenna
"WARNING": To avoid any possible damage to the car paintwork, please take
care when mounting magnetic GPS antennas. In particular make sure that there is
no dust or grit under the antenna. In some cases it may be required to add
additional protection to the paintwork prior to mounting the antenna to avoid
damage.
For correct, accurate operation of the GPS receiver it is absolutely essential that the
antenna is mounted correctly. There are several important aspects to consider when
mounting the antenna:
•The antenna must have a clear view of the sky in all directions. Note that it is NOT
enough that the antenna can see vertically upwards towards the sky, it must also be
able to see all the horizons as well. The GPS system actually gets very little positional
or speed information from the satellites directly above, it gets far more information
from satellites on or near the horizon. For example if the antenna was mounted in the
bottom of a "bucket", so it could upwards but no horizons, then the GPS system would
lock and provide positional information - but the accuracy would be very poor. In
practice this all means that the antenna should be mounted on the highest point of the
vehicle.
•The antenna must be mounted on a horizontal surface. The antenna must be mounted
on a horizontal orientation facing directly up. The underside of the antenna cannot
receive GPS information, similarly don't mount the antenna on a vertical surface.
•The antenna must not be covered in tape, in particular dark coloured tapes. Many tapes
absorb the weak GPS radio signal. In general, black tapes are the worst in this respect

13
Race Technology Ltd. VAT reg. 715 9671 09
After 12, King Street, Eastwood, Nottingham, NG16 3DA, UK
Tel: [phone] Fax: [phone]
Email: [e-mail]
as they contain high amounts of carbon - however, to be safe, avoid using any tape at
all.
•The antenna must not be subjected to high levels of vibration. Although the antenna is
physically robust to vibration, it can and does affect GPS reception, so isolate it as
much as possible.
•The antenna must be physically remote from sources of electrical noise. The GPS
radio signal is very weak and can easily be blocked out by radio interference, so to get
a good signal the antenna must be as far away from radio interference as possible. By
far the strongest source of radio interference is a gasoline engine's ignition system, so
keep the antenna away from all aspects of it including the engine management system,
coil, leads, distributor etc.
•Avoid trapping, pinching or kinking the antenna cable. The lead from the GPS antenna
to the receiver is a special very high frequency cable and it is not normally practical to
repair it - so if you do trap, pinch or cut it then the antenna will have to be replaced
and this isn't covered by the warranty. Do not try to feed the antenna cable through a
closure gap that is too small or compress it with a door seal or window seal.
•If at all possible, mount the antenna on a metal platform. The GPS radio signal is
amplified if the antenna is mounted on a metal plate (termed a ground plane), and the
bigger this plate is the better it will be for GPS reception. This is not essential for
correct operation, but it is desirable.
•Allow time for the GPS system to lock on before sampling data. The GPS receiver
typically takes one to two minutes to lock on to all the available satellites. The time to
lock onto satellites varies significantly with conditions but is minimised when the
vehicle is stationary.
4.1.3 Recommended mounting positions for the GPS antenna
•If the vehicle has a roof, this is the ideal place to mount the antenna.
•Alternatively, the best mounting position on a car may be the roll over bar or the top of
the windscreen frame.
•On a motorbike, mounting is a little more difficult, but the best compromise is on a flat
area of the tail unit, behind the rider.
•Poor mounting positions on a car include behind the front or rear windscreens.
Note: If you fail to adhere to the guidelines above, the GPS will still probably perform
"adequately" "most" of the time, however when conditions are more challenging (with
tree cover or bad weather etc) the positional accuracy will be significantly reduced.
4.1.4 Connecting the GPS module (if used)
Place the GPS antenna on the roof of the car, and screw the antenna connector onto the
gold connector on the back of the DL1 CLUB.

4.1.5 Connecting the power cable
If there is a cigarette lighter socket available on the vehicle, then the power lead
provided can be used as a simple convenient way to supply power to the DL1 CLUB. If
not, connect the DL1 CLUB to a fused power source, which is available when the
ignition is turned on. Connecting to a permanent power source will cause the DL1
CLUB to drain the battery continuously. Please do not connect anything to your car
unless you are confident in what you are doing!
4.2 Default Configuration
The DL1 CLUB can be configured by direct connection to a PC through the USB port
or by loading the configuration file on to the SD card which is put in to the unit. The
unit has a default configuration from the factory. This configuration has the following
settings for the analogue channels:
1. Spare input
2. Fuel level
3. Boost pressure
4. Air temperature
5. Oil pressure
6. Oil temp
7. Water temp
8. Start / stop control
•If the output driver option is enabled, the port 12 is used as the status output.
•Frequency inputs are set to map to wheel speeds 1-4, the high level RPM input is
enabled.
•All channels are transmitted on the serial port and all channels are logged to the SD
card.
•Automatic starting and stopping of logging are disabled.
If you need to change any of these configuration, start up the DL1 CLUB configuration
software.
Full instruction on how to configure the unit can be found in the online help which is
installed with the Analysis software package.
NOTE: The default configuration will need to be changed if the unit is used with an
ECU interface, failure to change this will result in no readings for any of the channels
listed above.

4.3 Logging data using the DL1 CLUB
4.3.1 Powering up the DL1 CLUB
Start the vehicle, wait a few seconds the "Power" LED will come on. Wait for a few
moments while the GPS receiver acquires a good positional lock. Once the GPS has a
lock, the GPS LED on the front of the DL1 CLUB will light up.
4.3.2 Insert an SD card
Take an SD or SDHC card and format it in the PC – the card must be formatted as
“FAT32” formatting it as “NTFS” or any other file system will cause unexpected
behaviour. When formatting is complete, remove the card and place it in the DL1 CLUB
slot. Once it is inserted wait a few seconds and the status light should start flashing
indicating that the DL1 CLUB is ready to start logging data. If the status light does not
start flashing, power down the DL1 CLUB and repeat the above steps. If the status light
does not flash on / off in equal measure then it could be one of the following problems:
1. SD Card detection error - one quick flash and off period
2. FAT file system initialize error – two quick flash and off period
3. SD card write error – three quick flash and off period
4. SD card read error – four quick flash and off period
4.3.3 Sampling data
To sample some data, simply press the "Start/stop logging” button on the front of the
DL1 CLUB. After a short pause, the "Logging" LED will illuminate, indicating that data
is being stored on the memory card. Drive the vehicle around for a while (slowly, safely
and in a responsible manner). To stop sampling press the "Start/stop logging" button
again. When you have stopped sampling data you can turn off power to the DL1 CLUB
unit. Never remove the card from the DL1 CLUB whilst it is logging data. This can
corrupt the card and the data will be lost.

4.4 Analysing data from the DL1 CLUB
Please note that the analysis software supplied with the DL1 CLUB is very powerful
and flexible and in most cases there are several ways that the same information can be
accessed or generated. This guide is intended to be a very brief introduction to the
software to enable you to get up and running as quickly as possible. When you require
more information, or find a problem carrying out any of the following procedures,
please refer to the on line help system that comes supplied with the DL1 CLUB.
4.4.1 Installing the SD card reader
If required, install the SD card reader according to the manufacturer’s instructions. On
many laptop computers the card reader is already built in and the external reader is not
required.
4.4.2 Installing the software on the PC
Before you can analyse the data from the DL1 CLUB you must install the software from
the supplied CD onto your PC. When you insert the CD-ROM, the installation program
should start automatically. Follow the onscreen instructions to install the software.
4.4.3 Loading the data into the software
To load the data from the SD card, remove the card from the slot in the front of the DL1
CLUB (after stopping logging) and place it in the card reader connected to your PC. The
data files on the SD card will appear in Windows Explorer as “.run” files separated into
directories named with the date on which they were recorded. Your test data file can
either be opened by "double clicking" on a “.run” file, or alternatively you can start the
software and go to "File” -> “Open". The data will now download – once it has done so,
click “yes” when you are asked if you want to process the data.
4.4.4 Display the track map and a graph of speed for the entire run
To view a map of the current data that is loaded select the “Results” -> “Track map”
menu, use the zoom button to navigate around the map. To display a simple graph of
speed for the entire run, select the “Results” -> “Graph” menu, and under the “Setup”
tab select “GPS Speed [mph]” as the first variable. Then click back on the “Graph” tab
to view the data.
4.4.5 Display your acceleration and braking times.
To display a full table of the acceleration times go to the “Results” -> “Performance
Calculations” menu and then select the “Timings” tab. A table of acceleration times
extracted from the data will be generated automatically.
4.4.6 Displaying lap and sector times
The first stage of the process is to add a “lap marker” to the track map. This is done in
the “track map” window by selecting the “add track marker” tool from the top right
hand corner of the track map window and adding a marker across a section of the track.

Next, go to the “Window” -> “Show Lap/Sector times” menu and you will be presented
with a list of lap times in a spreadsheet style table. You can add and name sectors
manually on the track map, but for this example we will add the markers automatically.
To do this go to the “Data” -> “Laps and Sectors” menu, select the “Sector setup” tab
and then click the “Automatically add sectors now” button. After a short pause, the
sectors will be shown in the table. Close the “Lap and Sector options” dialog box. If you
look at the track map you will see that a number of track markers and named sectors
have been added, also if you check the “Lap and Sector Times” table, you will see that
sector times are now displayed alongside the lap times.
4.4.7 Automatically generating a graph comparing speeds on two laps
You can automatically generate a graph showing the speeds for 2 laps most easily from
the “Lap and Sector times” table. Simply select the lap times of interest on the “Lap and
Sector times” table, as they are selected the cells will turn red. After selecting the laps of
interest, click the “graph” button at the top left hand side of the table. You will be
prompted for the type of graph you wish to generate, select “Speed versus Distance” and
click “Ok”. After a short pause a graph will appear with speed information for the laps
selected.
