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.
