Change of basic data
Use of the kit harness makes it possible for basic data to be selected for
SB (Super Bike) specification and ST (Stock Sports) specification.
For switching, use the white 2-pin connector located on the main switch connector
for the kit wire harness. The SB specification is available, when the connector with
a black lead is connected. When it is removed, the ST specification becomes
available.
A.
Setting Fuel Injection
Changes that may be made to fuel injection
CAUTION :
It is recommended that an A/F measuring instrument should be used
for this setting when checking the A/F figures on the instrument.
At high revolutions in particular, too lean a mixture may damage the engine.
The range of adjustment shown on the meter is ±25%.
As a guideline, a “1%” change effects a change of 0.1 in the A/F.

RANGE OF ADJUSTMENT OF THE VOLUME OF INJECTION F1 TO F9
F0: Transfer to the adjustment mode is shown in the display area at the bottom RHS
of the meter.
F1: This mode helps to stabilize idle running.
Too rich an A/F may foul the spark plug.
Too lean an A/F may cause unstable idle running and the engine may come to a
stop.
F2: The engine speed range of 3000 rpm or higher can be changed at a throttle
opening of 25% or less.
A change in F2 produces an effect on “feel” experienced during engine brake
activation and at the start of throttle opening.
Make a change of 2 to 5% at a time, while checking any change.
The rough A/F target is 12 to 14.
F3: Range of 25 to 90% throttle opening.
This range affects the feel, which is experienced as a result of the initial to half
throttle opening.
Jump-out at the start and hesitation at half-throttle opening may be solved by a
leaner A/F.
Make a change of 2 to 5% at a time, while checking any resulting changes.
F4: Adjusts the volume of fuel injected at any engine speed at a throttle opening of
90% or more. This mode constitutes the basic F5 to F9 data.
F5 to F9: Adjust the volume injected at individual engine speeds, at a throttle opening
of 90% or more, but note that the adjusted values in these modes are based on
the value adjusted in F4.
Example
Let F5 be “+3” after letting F4 be “+3”. The volume of fuel injected in the F5
range will be represented by “+6”.
Let F8 be “–6” after letting F4 be “+2”. The volume of fuel injected in the F8 range
will be represented by “–4”.

B.
Ignition Timing Correction
CAUTION :
This function corrects the gaps for the optimum ignition timing according to the
difference of the characteristics of the fuel used.
Ignition timing must not be set at too early a (plus side) timing since it may
cause problems. If no difference is felt as a result of correction, the ignition
timing should be set on the slower side.

FA-FC: IGNITION TIMING ADJUSTMENT RANGE
FA: Adjusts the ignition timing at a throttle opening of 25% or less and at an engine
speed of 3000 rpm or more, with a tolerance of ±15°.
FB: Adjusts the ignition timing at a throttle opening of 25% or more and 90% or less
and at an engine speed of 3000 rpm or more with a tolerance of ±10°.
FC: Adjusts the ignition timing at a throttle opening of 90% or more and at an engine
speed of 3000 rpm or more.
This range is apt to cause problems, according to engine tuning. In particular,
if the setting is on the + side, change degrees one by one while checking the
result.
C.
Adjustment of the RAM-Pressure Fuel Volume Correction
FD: This ECU is designed to correct the fuel injection volume in response to engine
speed.
Generally this requires no change.
This adjustment is made when a change occurs in the shape of the intake
compared with standard, or when the intake duct is removed to avoid its being
subjected to RAM pressure.
The adjustment is made with a tolerance of ±10 steps; +10 provides
approximately two (2) x as much corrected volume and –10 provides
a zero (0) corrected volume with no change due to engine speed.

Transfer to F0 mode
Keeping both the “SELECT” and “RESET” buttons pressed simultaneously, turn
on the main switch.
“F0 ” appears in the display area at the bottom RHS of the meter.
Transfer to the ECU applicable mode
Keeping both the SELECT and RESET buttons pressed simultaneously. “F1”
appears in the display.
Selecting and confirming the applicable mode
When the SELECT or RESET buttons are simultaneously pressed, the display
shows the next application or reverts to the previous mode.
Keeping them pressed down allows the display to go step by step to the next
mode or to revert to the previous mode.
F1⇔F2⇔F3⇔F4⇔F5⇔F6⇔F7⇔F8⇔F9⇔FA⇔FB⇔FC⇔FD⇔FE⇔F1
When the mode you want to change appears, simultaneously press the SELECT
and RESET buttons in order to conform the desired mode.
Changing and confirming the applicable value
When confirmation is made, “FX_YY” appears in the display.
YY indicates the applicable value and “ 0” the standard value.
For fuel volume correction, % is shown and for ignition timing correction, the
timing angle is shown.
To change the “YY” value, press the SELECT or RESET buttons and change the
numerical value.
To confirm the changed value and to transfer to another mode, simultaneously
press the SELECT and RESET buttons.
The value “YY” disappears from the display area in preparation for the
adjustment mode to be switched.
Finishing the adjustment mode
Turn off the main switch, and the adjustment mode will end.
Initialization of Value Changed
FE: Keeping the SELECT and RESET buttons simultaneously pressed, the transition
to this mode brings about initialisation.
“FE_YY” is shown in the meter screen. The numerical value “YY” represents the
value of each of the 13 modes from F1 to FD, but since it does not indicate which
mode has been changed, it is necessary to transfer to the adjustment mode in
order to check.
If “ 0” is displayed, it indicates an absence of changes and no initialisation is
needed. Turn off the main switch to end

Initialization
(Bring all settings to “0”.)
Press the “RESET” or “SELECT” button with “FE_YY” displayed. “FE_88” will appear.
While checking this display, simultaneously keep both the “RESET” and “SELECT”
buttons pressed.
“FE_ 0” will be displayed and this completes initialisation. Turn off the main switch to
end.
• While each applicable value is being changed, the value immediately preceding is
memorised in the ECU, even with the main switch off.
• The set values changed are retained, even after the battery has been removed.

CAUTION :
• The spring is longer overall than standard, because of its specification.
For setting up, use the collar supplied instead of standard.
• The pre-load is set to provide 0 mm with the fork assembly fully extended and
with the adjuster projecting 19 mm. When the front forks are free from load
other than their own weight, the apparent pre-load is approximately 7 mm,
because the rebound spring keeps the fork from rebounding fully.
• The spring rate is identified by the number of lines on its end.
