Installation of the QwikData Data Logger Unit:

Important Notice: When installing data log unit avoid RF and or EMI signal interference and make sure all grounds are connected

directly to the negative side of the battery. Keep sensor wiring away from ignition wires. Try to keep all data log unit wiring as far as
possible from CD boxes and wiring. Do not mount the data log next to ignition box or ignition coils. You will want as much distance
between the data log and these devices as possible. Thermocouples and thermocouple extension must also be kept away from ignition
wires, ignition box and coils. If wires have to cross, try to have them cross at a right angle. Avoid paralleling Data log wires with any
ignition wiring (Primary or Secondary).

As the QwikData accelerometers are mounted inside the data logger unit, the unit must be mounted in a particular orientation to obtain
accurate acceleration data. The unit must be mounted approximately level and horizontal with the QwikData logo parallel to the
centerline of the car. If possible, the box should be mounted along the centerline at the center of gravity of the car. Mounting in the
cockpit in front of the shifter is often a convenient location. Mounting QwikData with the connectors facing the front of the car will
display left turns and longitudinal acceleration as positive numbers (right turns and braking are displayed as negative numbers). Don't
be overly concerned if you cannot meet these criteria as the measurement errors induced are not great and in general you should be
more concerned with relative acceleration figures, not the absolute numbers. Although not required, some sort of vibration isolation
is usually desirable to prevent noisy accelerometer readings due to vibration. Mount using high-density foam rubber under mounting
screws. Velcro tape is also a good alternative as it allows the box to be easily removed and provides some vibration dampening.

Pressure Sensors

Five pressure sensors are available in pressure ranges:

1 (-15) Vacuum Transducer
2 0-15 psi pressure sensors (Fuel pump) etc.
3 0 - 100 psi pressure sensors (Oil) etc.
4 0-500 psi pressure sensor (Trans Pressure) etc.
5 0-2500 psi pressure sensor (Brakes or Nitrous) etc.

The sensors are provided with a male 1/8 NPT fitting that is compatible with most vehicles (pipe adapters can be used if a different
thread size is needed). Note: Pressure sensors should not be mounted directly to the engine, as excessive vibration can destroy the
sensors. Mount the sensors remotely with an aluminum block, and connect to the engine with small, flexible tubing.

Temperature Sensors

The temperature sensors provided in some QwikData packages are high quality thermocouple devices. Three thermocouples are
provided to measure temperatures such as oil temperature and coolant temperature. These thermocouples are provided with 1/8 NPT
compression fittings that can easily be installed in a similarly threaded hole. To install these thermocouples, thread the compression
fitting into the hole and tighten the base of the fitting (not the compression nut) to prevent leaks. Insert the thermocouple into the hole
and then tighten the compression nut until the thermocouple is secured in place. Connect a thermocouple couple extension cable to
each thermocouple temperature sensor.

Exhaust Gas Temperature Sensors

The exhaust gas temperature (EGT) thermocouples are typically mounted in each of the exhaust header pipes close to the header
flange (usually about 3" away). The exact location is not critical but you should try to mount all the EGTs at approximately the same
location in each header for consistent measurements. The EGT thermocouples are supplied with a compression fitting similar to the
general purpose thermocouples. The compression fitting consists of four parts; a bung, an adapter, a ferrule, and a compression nut.
To install the EGT thermocouples, you need to drill a 9/16” clearance hole in the exhaust header and then weld the bung into the
header.

NOTE: The bung is threaded with a 1/8” NPT and MUST be mounted with the inside taper facing out.

Once the bung has been welded in place, thread the adapter into the bung and tighten. Place the ferrule into the adapter and loosely
thread the compression nut onto the adapter. Insert the EGT thermocouple into the compression fitting and tighten the compression
nut to secure the thermocouple. Insert the EGT thermocouple into the compression fitting until the tip is approximately in the center
of the header. Secure by tightening the compression nut.

TK-4 Thermocouple Converter Installation

The TK-4 thermocouple converter unit is required to provide signal conditioning of the thermocouple signals. All eleven thermocouples
installed above are connected to a thermocouple converter. The thermocouple cables provided with the thermocouples are four feet
long. When installing the thermocouple converter unit, make sure it is within reach of all the thermocouple cables. Mount the TK-4
thermocouple converter unit using the four mounting holes in the mounting flanges. The converter unit can be mounted anywhere
within reach on the thermocouples including under the hood. If the unit is mounted under the hood, avoid locations very close to the
exhaust headers to prevent excessive temperatures. Also try to mount the converter unit vertically with the thermocouple connectors
pointing down to prevent water accumulation in the converter unit (The converter unit enclosure is splash proof except for the
thermocouple connectors). If the converter unit is mounted in a protected location such as the interior of the vehicle, then the unit can
be mounted in any orientation. Once the TK-4 thermocouple converter unit and the thermocouples are installed, connect the
thermocouples to the converter unit. The general purpose thermocouples have a male thermocouple connector attached for easy
disconnection and removal. These thermocouples are provided with a four-foot thermocouple extension cable. Connect the female
connector on the extension cable to the thermocouple and the male connector to the TK-4 Thermocouple Converter unit.

Wheel / Shaft Speed Sensors

These sensors are supplied with two rare earth magnets and a sensor pickup and can be used to measure either wheel speed or shaft
speeds. The two magnets are mounted equally spaced around the rotating object (wheel or shaft) and the pickup is mounted on a
stationary object. For proper operation, the magnets must pass within a maximum of 1/4 inch of the pickup. Because of this
restriction, it is very important to mount the pickup on something that moves very little relative to the magnets.

For example, if the magnets are mounted on the drive shaft, they should be either mounted close to the transmission end or close to
the rear end and the pickup should be mounted directly to the transmission or the rear end respectively. Similarly, if the magnets are
mounted to a wheel, the pickup must be mounted to a suspension piece that moves with the wheel. The magnets can be either
epoxied in place or taped in place with duct tape.

NOTE: As supplied by the factory, these sensors are configured to measure RPM as they are typically used to measure
input shaft and output shaft RPM. If one of these sensors is used to measure vehicle speed, the sensor must be
calibrated accordingly. The calibration of the speed sensor is unique to each installation. (Refer to the

Sensor

Calibration

section.)

Wiring Harness Installation and Connection

To provide a splash-proof system and make installation as easy as possible, QwikData uses high-grade waterproof connectors and an
external wiring harness instead of having terminals on the box. Push the wiring harness connector(s) onto the mating male plug(s) on
the QwikData box until you hear a “click”. If your package included the Advanced QwikData unit, there will be two connectors on the
QwikData box. The harness with the DB9 connector is connected to the right hand plug (as viewed from the plugs on the QwikData
unit). Refer to the pictures below.

Brochure #63-0282

To make installation as easy as possible, the wiring harness provided is completely assembled with connectors that mate to the

supplied sensors. Each sensor is connected to the QwikData unit by simply mating the appropriate connectors. (Refer to the QwikData
Reference Manual on the CD ROM for a description of the wiring harness and the sensor connections.)

Route the wiring harness as needed to make connections to the installed sensors. To connect the circular connectors on the wiring

harness to the sensors, push the mating connectors firmly together and then turn the locking ring clockwise to lock the connectors
together.

Bracket Drag and Import/Compact Drag Racing Package Sensor Connections

Connect the TK4 Thermocouple Converter box to the harness connector labeled “THERM CONV”. The TK-4 Thermocouple Converter

box is a four-channel unit, with the channels labeled A through D. The EGT Thermocouples then plug into the TK-4 Converter box. By
default, the EGT connected to channel A of the TK-4 Converter box is labeled as EGT 1 in the software and so on. You can easily change
the channel’s names using the QwikData software to match the correct cylinder numbers for your installation.

Connect the shaft speed sensor located on the drive shaft to the connector labeled “SPEED”, the connector marked “FUEL PRESS” to

the fuel pressure sensor, etc.

Advanced Drag Racing Package Sensor Connections

Connect the harness connector marked “THERM CONV 1” to the connector on the side of the TK-4 Thermocouple Converter unit #1,

the harness connector marked “THERM CONV 2” to the connector on the side of the TK-4 Thermocouple Converter unit #2, the harness
connector marked “THERM CONV 3” to the connector on the side of the TK-4 Thermocouple Converter unit #3. The TK-4 Thermocouple
Converter box is a four channel unit, with the channels labeled A through D. The EGT Thermocouples then plug into the TK-4 Converter
box. By default, the EGT connected to channel A of the #1 TK-4 Converter box is labeled as EGT 1 in the software and so on up to
channel D of the #2 TK-4 Converter box which corresponds to EGT 8. You can easily change the channel’s names using the QwikData
software to match the correct cylinder numbers for your installation. Channels A and B of TK-4 Converter box #3 are labeled as Water
Temperature and Oil Temperature but can be used to measure any temperatures you want. Connect the shaft speed sensor located
on the input shaft to the connector labeled “Speed 1”, the shaft speed sensor located on the output shaft to the connector labeled
“Speed 2”, the connector marked fuel press, to the fuel pressure sensor, etc.

To remove a connector once it is installed, insert a small flat blade screwdriver under the locking clip. Lift the clip while pulling on the
connector (never pull on the wires).

Connection To Battery Power

Power is connected to the QwikData box using the red and black wires on the wiring harness. Connect the red wire to a switched 12V
source (e.g. output of ignition switch) and the black wire to a good ground. The recommended grounding point for most installations
is the ground bolt located on the back of the right side cylinder head. The black wire in the wiring harness is supplied with a terminal
to fit this grounding bolt. Do not connect the red wire directly to the battery, as this will put an unnecessary current draw on your
battery (approximately 250 ma) when the ignition switch is off. QwikData does not need continual battery to preserve data and
configuration settings.

Note: A good system ground is very important for proper operation of the QwikData system. Whenever possible, connect the ground
as described above. It is also very important to have a good ground strap between the engine and the chassis.

Engine RPM Connection

Two un-terminated wires are provided on the main harness for RPM input. Most electronic ignition systems provide a tach output and
these wires should be connected directly to this output. The purple wire should be connected to the tach signal (+) and the black wire
should be connected to a good ground or (-) signal terminal if provided by the ignition system.

WARNING!!!: THIS INPUT SHOULD NOT BE CONNECTED DIRECTLY TO THE IGNITION COIL.

NOTE: The RPM input is calibrated for a typical 8 cylinder application in the default setup but this may require
calibration depending on the installation, (see Reference manual on the QwikData CD ROM for details).

Data Logging On/Off Switch

With the QwikData system, data logging can be started and stopped either automatically based on sensor values or manually with a
switch (default configuration). If manual-logging control is desired, a single pole on/off toggle switch must be installed in the vehicle
and connected to the two logging control wires (yellow and black) labeled “LOG ON/OFF” in the main wiring harness. One wire should
be connected to each terminal on the toggle switch. Data logging will start when the toggle switch is turned on (connecting the black
and yellow wires together) and stop when the switch is turned off. If automatic data logging is used, these wires are not needed.

SOFTWARE INSTALLATION

The PC software utilizes a standard Windows installation program. As a precaution, you should shut down any other applications that
may be currently running before starting the QwikData installation. Insert the QwikData CD into your CD-ROM drive.

To run the QwikData analysis software, you must install the software on a PC with the following minimum requirements:

When the “Installation Type” screen is displayed, click on the QwikData package that you are using and click on the “Next” button to

proceed.

Follow the on-screen instructions to complete the software installation.

NOTE: The setup program must always be utilized if installing the software on a different machine. Simply copying the ".exe" program

over will not work.

FIRST TIME POWER-UP

Connect QwikData to one of your PC's spare serial ports using the gray serial cable with the 9 pin "D" type computer connector (Note:

This is not waterproof, so keep this stowed in a dry place during operation). If your computer only has a 25-pin connector, then you
must purchase a 9 to 25 pin adapter (available anywhere computer products are sold). The QwikData Analysis software automatically
searches all the available COM ports on your PC to find the QwikData unit. The first time you connect the QwikData unit to your PC,
this search process may take some time. Once communications with the QwikData unit is established, the software remembers the
COM port. The next time you start the program, it will check this COM port first and unless you connect the QwikData unit to a different
COM port, communications will be established quickly.

NOTE: If you are using the QwikData Analysis software to analyze previously logged data that has been stored on you

PC hard drive (historical data) and the QwikData unit is not connected to your PC, simply click on the QwikData logo
with the left mouse button to bypass the auto-search function. The program will start-up shortly thereafter.

If you get the flashing red message "Not Connected" then the PC program could not communicate with the QwikData unit. Ensure

that the QwikData unit is receiving 12 volts and that the QwikData unit is connected to an available COM port on your computer. Then
either re-start the program or select “Re-initialize Comm” from the “Tools” menu.

Now select the “Download Setup” option from the “Setup Menu” and click “OK”

If the QwikData unit has any data stored in its memory, this data will be erased and the warning message “Downloading will erase all
saved data. Continue?” will be displayed.

Click on the “OK” button to proceed and the downloading progress bar will appear.

Once the download is complete, the setup information is permanently stored in the QwikData unit and you do not have to download
the setup information again unless you change the setup.

Sensor Calibration

If you are using the sensors provide in the QwikData package, then the default setup file already has all the calibration information for
the sensors. The only exception is if you want to use the drive shaft speed sensor to measure the vehicle speed (the default setup file
calibrates this sensor in RPM). The calibration of this sensor for vehicle speed will be unique for every vehicle.

To calibrate this sensor for vehicle speed, select “Digital Channels” from the “Setup” menu to display the Digital Channel Setup Screen.

Digital Sensor Calibration

QwikData configuration is performed in the “Setup” menu:

NOTE: After making any setup changes, the new setup must be downloaded to the QwikData unit using the “Download
Setup” option in the “Setup” menu before the changes are effective.

Digital Channel Setup

This menu selection allows you to select whether or not each of the digital channels is to be enabled for viewing or logging, and to
enter in descriptive and calibration information for each channel. For each channel that you intend to use, click the “Channel” Box to
enable that channel. Until the channel is enabled, no additional information can be entered for that channel.

Name: Enter a descriptive name for each channel (will appear on graph) e.g. RPM.Choosing Channels

Choosing Channels

While QwikData offers tremendous flexibility by allowing you to configure each channel individually, the standard QwikData packages
are provided pre-configured and you will not need to modify the channel selections unless you are adding optional sensors to the
standard package.

Analog Inputs

Analog Inputs can measure signals in the 0-10 volt range. Voltages above 10V (24 Absolute maximum) will be displayed as 10V.
Channel 16 , will read voltages up to 20V via a 2: I Voltage Divider. Factory settings configure your unit with Channels 9 and 10 to
reading the internal accelerometers, Channel 16 is configured to read battery voltage. If you do not want to take these readings and
require the extra channels, see the jumper page #43.

Digital lnputs

These are inputs that can measure a digital (on/off) signal. As well as strictly reading if a signal is on or off (such as monitoring a brake
light switch), QwikData can measure the frequency of a signal (Tach. output or wheel speed sensor), the on or off period (fuel injector
pulse), or count the number of times a signal goes from on to off (or off to on).

There are 3 types of Digital Inputs. You must correctly identify your inputs before proceeding!!!

Logic signal

Channels 1 and 6 are configured to measure signals that switch between a high (12 or 5 volts) and low (ground) voltage by themselves.
This may be a tach. signal, a signal generated from another electronic device (1TL or CMOS level), an injector input etc.

WARNING!!!
Do not connect any digital input directly to an ignition coil as the electrical noise may cause improper operation of
QwikData or damage the unit (Use MSD tachometer adapter #8132 to connect to the negative side of a coil).

Grounding Type Switch

Channels 2,3, and 5 are configured with a pull-up resistor so that a grounding type switch can be read, e.g. when using one of our
wheel speed sensors the normal reading is 12 V due to the pull-up resistor, then the signal goes to ground level when the switch passes
by the magnet.

Low to high signal

Channel Four (4), is configured with a pull-down resistor in the basic
QwikData unit to allow it to read signals with either the presence or absence
of 12V. e.g. when monitoring an ignition switch the signal is either a 12V
signal or an open circuit (not ground) when the switch is off. Digital Input
Channels can be changed to be any of the 3 types listed above by changing
internal jumper settings. See the

“QwikData Jumper Configuration”

on

page 43.

Proceed with caution when changing the digital channel
Jumper settings.

Type: Select Input type from pull-down menu.

Pure Digital Select when you simply want to .determine status of a two state input (e.g. Brake light on/off).

Duty High Used mostly for computer cars, E.g. to measure the percentage of time an input (e.g. injectors) is high.

Duty Low Used mostly for computer cars, E.g. to measure the percentage of time an input (e.g. injectors) is low.

On Time Used mostly for computer cars, E.g. to measure the absolute time (in milliseconds) an input (e.g. injectors) is

high.

Off Time Used mostly for computer cars, E.g. to measure the absolute time (in milliseconds) an input (e.g. injectors) is

low.

Frequency Rise Used to measure the frequency of an input (e.g. Tach, signal, wheel speed sensor) by measuring the rising edge

of a signal. The units for frequency are Hz x 100.

Frequency Fall Used to measure the frequency of an input (e.g. Tach. signal, wheel speed sensor) by measuring the falling edge

of a signal. The numbers generated by using this setting are usually the same as those measured by selecting
“Frequency Rise”, but this setting may be preferable with certain types of signals (e.g. those with lots of
electrical noise). The units for frequency are Hz x 100.

Counter Rise Used to count the number of transitions from low to high of a variable. This is an alternate setting for inputs

such as “lap beacons”.
