Installing the USB driver
1–7–1 Before installation
Installation of the USB driver is required when connecting the interface cable to your computer for the
first time. Connection to the ECU is not required when installing the driver.
* There are two installation methods.
(1)
Install from the CD.
(2)
If you cannot use the CD when you connect the interface cable for the first time, copy the driver
files from the CD onto the computer and then specify the driver files to install them.
The driver files are in the “KITUSBCDM 2.02.04 FTDI DRIVER” folder on the CD. Copy the
whole folder onto the computer.
* The appearance of screens may differ depending the type of PC in use.
1–7–2 Installation Procedure (Installing from the CD)
(1)
Connect the interface cable to the USB port of the computer.
After connecting the cable, an icon and message appear in the computer’s task bar.
(2)
Insert the CD in the CD drive. When the “Found New Hardware Wizard” screen appears and asks
“Can Windows connect to Windows Update to search for software?” select “No, not this time” and
click “Next”.
–5–
(3)
Check “Install from a list or specific location” and click “Next”.
(4)
Check “Search for the best driver in these locations” and “Search removable media (floppy, CDROM...)” and then click “Next”.
* When installing from driver files copied onto your computer, check “Include this location in the
search” and select the folder where the files are saved.
–6–
(5)
If the following screen appears, click “Continue Anyway”.
–7–
(6)
When the “Completing the Found New Hardware Wizard” screen appears, click “Finish”.
Installation of the USB driver is now complete.
After clicking “Finish”, please wait. Installation of the serial port driver will soon start.
–8–
(7)
Serial port driver installation
After the USB driver is installed, the following message appears in the task bar.
(8)
When the “Found New Hardware Wizard” screen appears, check “No, not this time” and click
“Next”.
–9–
(9)
Check “Install from a list or specific location” and click “Next”.
(10) Check “Search for the best driver in these locations” and “Search removable media (floppy, CDROM...)” and then click “Next”.
– 10 –
(11) If the following screen appears, click “Continue Anyway”.
(12) When the “Completing the Found New Hardware Wizard” screen appears, click “Finish”.
All installation is now complete.

1–7–3 How to Change the COM Port
When two or more devices using serial ports are installed on a computer, the COM ports increase.
(COM4, 5, 6...)
If you want to select an optional COM number, you can change it with the device manager.
Changing procedure
(1)
Connect the interface cable.
(2)
Right click on “My Computer” and open “Properties”.
(3)
In “Properties”, open “Hardware” and “Device Manager”.
(4)
Open “Ports (COM and LPT)”, select the desired serial port and right click to open “Properties”.
(5)
Select “Port Settings” and click “Advanced”.
– 12 –
(6)
Select the desired COM port in “COM Port Number” and click “OK”.
Close the Device Manager and reopen it. The COM number is now changed.
CAUTION:
In the above screen, some COM numbers may be marked “in use”.
These are COM numbers that have been registered once to another device.
Selecting one of them now will write over the existing setting, so you may have to reset the
original device when you next use it.
– 13 –
1–7–4 Uninstallation Procedure
(1)
Connect the interface cable.
(2)
Open “Device Manager”.
(3)
Open “Ports (COM & LPT)”.
(4)
Select the desired serial port and right click.
(5)
Click “Uninstall”.
– 14 –
(6)
Open “USB Controller”.
(7)
Select “USB KIT IF Cable” and right click.
(8)
Click “Uninstall”.
* If reinstalling the driver, you must first uninstall it.

2–1–2 Targets for setting of the YEC FI Matching System and precautions
(1)
Shifter / Cut Time
In case ignition cut time is short: Shift loss is reduced but there may cause hard gear throws.
In case ignition cut time is long: Gear throws will be easier but shift loss will increase.
CAUTION:
If ignition cut time is too short, the drive system may be damaged.
(2)
Comp. FUEL / Map 1 (3) Comp. FUEL / Map 2 (7) Comp. FUEL / All Area
It is recommended that adjustment be made while constantly checking A/F. Aim for A/F 12 to 13.
Change at one time should be changes of 2% to 5% and especially for changes on the reduction
side, (in case of becoming thinner), pay attention to the A/F value while changing.
CAUTION:
If A/F is too thin, may relate to damage of the engine.
(4)
Offset IGNITION
Adjust to the spark advancing side if too excessive, may possibly damage the engine. Sufficient
care is needed when making adjustment. In case no change is seen when spark advancing is
selected, or when at a loss to which side adjustment should made, it is recommended that
adjustment be made to the spark retarding side.
CAUTION:
Adjusting to the spark advancing side may possibly damage the engine if too extreme.
(6)
Comp. ETV / Engine Brake
CAUTION:
If open setting of the throttle is made to reduce engine braking, the engine revolution may not
drop enough at corners and over-speeding may risk causing of serious accidents. Especially, a
change in gear ratio, or the running on a course for the first time, will require paying of sufficient
attention.
(9)
Comp. RAM Correction
Use only when the A/F diverges with increased vehicle speed.

For control of engine revolution, obtain the necessary engine revolution from the following
formula and input the obtained value.

Function explanation
4–2–1 Graph editing function on MAP screen

Data editing function on graph point
Clicking on graph: Graph is selected and also the editing point of the revolution nearest to the
clicked point is selected.
Drag and drop of graph data: Edit point is selected with left button down. By moving up and down,
changed to the editing point nearest to the release point. (Direction of revolution is not changed)
4–2–2 MAP editing function on TABLE screen
Editing by key inputting is possible. When a value outside the data settable range is imputed, a warning
message dialog is displayed and a value for which data settable value is automatically set.
* When a figure key or minus key is inputted, becomes in a cell editing status and key inputting status.
Also becomes in a cell editing status by double clicking of the mouse.

Editing of axis cell
Revolution axis, throttle opening axis may both be numerically inputted or may be changed by
[Page Up]/[Page Down] keys. The input value is limited by the maximum input range or by the value
of the adjacent cell value.
CAUTION:
The Comp. FUEL / Map 1 axis and Comp. FUEL / Map 2 axis (engine rotation and throttle opening)
are common. When either one is changed, the same value is reflected on the other.
4–2–3 Selecting of plural cells, editing, copy function on the TABLE screen
When in a status with cursor at an optional cell, drag by mouse and a plural cell selecting status is seen.
* When a numerical key or minus key is inputted, becomes in a cell editing status with key inputting
status. Double clicking of the mouse releases multiple cell selection and becomes in cell editing status.
– 35 –
4–2–4 Pasting function of plural cell data on TABLE screen
Data array copied in a plural cell selecting status may be pasted by {Ctrl} + {V} key on any optional cell
other than the revolution increment and throttle opening increment axis cells. Also, plural cell data copied
from Excel, etc. may be pasted via the clip board.
* However, when plural cell data is copied on the clip board, posting cannot be made in a plural cell
selecting status.
In case pasting of data array exceeding the cell range in which pasting on the Table is attempted, the
data exceeding the pasting possible range is ignored, The pasted data is consistently rounded to a
minimum increment figure. In case of values outside the data settable range, the limit value within the
settable range is automatically set.
