applications that may be running. For Windows Vista,
you must disable the User Account Control (UAC)
during installation. If you are not familiar with the UAC,
please refer to the Vista UAC Tech Note on our
website's Tech FAQ for details.

Use the Windows Explorer or the Run command

from the Windows Start Menu to launch setup.exe in the
PC_Link_Nitrous folder on the CDROM or the setup.exe
file downloaded from our website. InstallShield will install
the software in an appropriate folder under Program
Files.

Repeat the installation process for Nitrous Log.

Use the Windows Explorer or the Run command from
the Windows Start Menu to launch setup.exe in the
Nitrous_Log folder on the CDROM or the setup.exe file
downloaded from our website. InstallShield will install the
software in an appropriate folder under Program Files.

Once InstallShield has completed the

installation, PC Link Nitrous and Nitrous Log will
appear on the Windows Start Menu. You can then
launch them just as you would any other Windows
program.

The programs require the Monospace 821 BT

fixed pitch printer font in order to properly align
columns when printing. The Monospace 821 BT font is
included in the distribution media and automatically
copied to your Windows Fonts folder during
installation. A backup copy is also placed in the
program folder. If you accidentally delete this font, use
the Install New Font command from the Fonts folder
File menu. The filename associated with Monospace
821 BT is monos.ttf.

PC LINK NITROUS SOFTWARE

Before the nitrous controller is armed, you can

download or upload data with PC Link Nitrous.

After PC Link Nitrous is launched, the main

screen appears blank. When launched for the first
time, the program uses COM1 as the default port. In
most cases, you will have configured the nitrous
controller USB interface to use a different COM port,
such as COM5. Use the Port Setup command on the
Communications menu to select the correct COM port.
The program will remember the new port setup.

You have two options for obtaining data for

editing. You can open a previously saved setup file by
using the Open File command on the File menu or you
can download data from an attached nitrous controller
unit by using the Download Data From EEPROM
command on the Communications menu. Note that
nitrous controller setup files use a .dat extension. You
should create a separate folder to store these files. A

sample setup file (Sample.dat) is included in the
program folder.

Once you have nitrous controller data, you can

edit various parameters, general setup options, and
controller scale factors. You can print the displayed
nitrous controller setup data by using the Print
Parameters command from the File menu. When you
open a file or download data from a unit, the data is
stored in a buffer memory. Once you have completed
all your edits, you can save the data in buffer memory
to a file or upload it back to the unit by using the
appropriate command from the File or Communications
menu.

CONTROLLER SCALE FACTORS

Controller scale factors shown in Figure 7 are

generally established during initial setup (see page 15)
and with the exception of the data logging interval will
probably remain unchanged for a particular vehicle.
Scale factors that you can set include:

RPM Pulses/Rev – RPM pulses per revolution

(PPR). Some general guidelines follow, based on the
type of signal connected to the controller RPM input:

Tach signal. This includes aftermarket CD
type ignitions with a tach output. In most cases
PPR= N/2 where N is the number of cylinders.
For example a 4 cylinder engine would require
PPR=2 and a V8 engine would require PPR=4

Distributor type ignition with connection to
Coil- terminal. Same as for a tach signal. Use
PPR= N/2 where N is the number of cylinders.

Wasted spark coil pack (distributorless
system) with connection to Coil- terminal. Use
PPR=1.

Coil on plug (no wasted spark) with
connection to Coil- terminal or logic level drive
signal from the ECM. Use PPR=0.5

RPM Debounce – RPM signal filtering in

milliseconds (msec). Use the default value of 0.50
msec for most applications. Ford 4.6L modular V8
engines will require a value of 3.5 msec.

VSS Frequency – sets the correct scaling for

vehicle speed based on the signal frequency at 60
MPH. Values vary widely between different vehicle
applications. Unless you have a scopemeter to
measure the actual signal frequency, some trial and
error using the Nitrous Log software to display the
vehicle speed will be required to establish the correct
setting. If you are not using the VSS input, you can
ignore this parameter.
