Introduction
With the gradually increasing trend of electronic fuel injection engines, the EZECU® series – Rich
Fi ECU (Engine Control Unit) developed by IC Leader Technology Corporation is announced dedicated
for SUZUKI DCP (Discharge Pump) compliant fuel injection systems to provide a fuel tuning 3D table
with 59×10 cells and up to 250 fuel-tuning levels for each cell. Unlike other piggyback products that
generate a faked signal (MAP, TPS, or MAF sensor) to cheat the factory ECU, Rich Fi ECU drives the
DCP directly according to a base fuel injection width by the factory ECU. Furthermore, Rich Fi ECU
can detect various crankshaft flywheel types automatically by our built-in intelligent algorithm.

TPS Voltage Calibration
The voltage values of TPS for each bike/scooter should be calibrated before operating correctly
because the 0% and 100% throttle may be mapped to different voltages for different TPS models. For
example, some TPS outputs 0V through 3.1V corresponding to 0% through 100%, while some TPS
outputs 0.7V through 4.1V corresponding to 0% through 100%. Consequently, the application software
provides semi-auto detection and manual input for the TPS calibration values.
As shown in Figure 3-5, there are two “Copy” buttons and two fields for inputting the voltage
values corresponding to 0% and 100% throttle, wherein two “Copy” buttons are responsible for the
semi-auto input function and two fields are responsible for the manual input function.

Connect Rich Fi ECU and your bike/scooter;
Connect the USB cable between Rich Fi ECU and your computer;
Execute the application software;
Turn one the bike/scooter power but do not start the engine and confirm the blue power LED
on Rich Fi ECU is lighted;
Press the upper “Copy” button to copy TPS voltage of 0% throttle;
Rotate the bike/scooter’s throttle to 100% and hold, press the lower “Copy” button to copy TPS
voltage of 100% throttle; and
Release the bike/scooter’s throttle.
Since the TPS is made of resistor, the voltage output may vary according to different working
temperatures. Consequently, we suggest to increase the fully-closed TPS voltage by 0.1V and to
decrease the fully-opened TPS voltage by 0.1V.
In this manner, the TPS mapping range for your bike/scooter can be detected. Both TPS setting

values can be saved into the fuel map file. If user wants to update the fuel map again, the TPS
calibration process can be skipped by reloading the saved TPS setting values.
Finally, user may use a precise voltage meter to measure TPS voltage values corresponding to 0%
and 100% throttle and then fill the measured voltage values into the TPS calibration fields.

Real-Time Engine Status
As shown in Figure 3-6, real-time engine status includes a RPM gauge, a TPS % gauge, an ECU
fuel injection time, a Rich Fi ECU fuel injection time, an ECU injection mode, and a crankshaft
flywheel type.
Figure 3-6
Real-Time Engine Status
The ECU injection mode shows the number of fuel injection times within the 4-stroke cycles. This
is set by user while uploading the fuel tuning map. For SUZUKI Address without O2 sensor, the
crankshaft flywheel type shows “1” to indicate that there is only one tooth on the flywheel. For SUZUKI
Address/Music with O2 sensor and Tekken / V125S, the crankshaft flywheel type shows “12-2” to
indicate that there are 12 teeth on the flywheel with 2 missing teeth.

3. Application Software
Rich Fi ECU provides a fuel tuning map with 500 RPM through 15,000 RPM by programmable
10-level TPS resolutions with 1% step (the default TPS levels are 0%, 5%, 10%, 20%, 30%, 40%, 50%,
60%, 80%, and 100%). The 500 RPM through 15,000 RPM can be set by selecting the RPM resolution
as one of 250 RPM, 500 RPM and 1,000 RPM. Fuel tuning maps with 500 RPM and 1,000 RPM
resolutions are shown in Figure 3-8 and Figure 3-9, respectively.

Figure 3-9
Fuel Tuning Map with 1,000 RPM Resolution
In general, the 1,000 RPM resolution is recommended as a startup basis. The fuel tuning map with
1,000 RPM resolution is formed as a 15 by 10 table. Since there are fewer cells, it is easier for roughly
tuning the fuel map. The application software will average and interpolate the fuel tuning map values
into each cell of the 250 RPM fuel tuning map. User does not need to worry about losing control
precision due to selecting the 1,000 RPM resolution.
18
EZECU® – Rich Fi ECU User’s Manual
3. Application Software
If user wants to increase resolution for tuning the fuel map, the 500 RPM resolution can be selected.
The fuel tuning map with 500 RPM resolution is formed as a 30 by 10 table. Since there are double cells
as compared to the 1,000 RPM resolution, user may tune the fuel injection amount in a more detailed
order. The application software will average and interpolate the fuel map values into each cell of the 250
RPM fuel tuning map. User does not need to worry about losing control precision due to selecting the
500 RPM resolution.
The maximum resolution is to set as the 250 RPM resolution. The fuel tuning map with 250 RPM
resolution is formed as one 59 by 10 table. Since there are almost double cells as compared to the 500
RPM resolution, user may tune the fuel injection amount in a most detailed order.
When editing the fuel tuning map, user may mark an area to perform addition/subtraction/clear all
by pressing corresponding buttons below the fuel tuning map. The addition/subtraction button will
add/subtract each cell inside the marked area by the value of the addition/subtraction value field. The
clear all button will reset each cell of the fuel tuning map to 0.
The fuel injection time is calculated as follows:
Fuel Injection TimeRich Fi ECU = ( Fuel Injection TimeFactory ECU − DCP Turn On Time) × (100% ±
X%
)+
2 .5
DCP Turn On Time
, wherein the X% is the 32-bit bilinear interpolated percentage value by the Rich Fi ECU with the range
of 0.00% ≤ X ≤ +250.00%.
The initial values of the fuel tuning map are all 0s. That is, the fuel injection time of Rich Fi ECU is
the same as the factory ECU. If user has an enlarged cylinder from 125CC to 164CC, the enlarged
percentage is ((164−125)÷125)×100% ≈ 30%. If the fuel injector remains the same, the fuel tuning map
may be all filled by 30% as a tuning basis. Use a wideband oxygen sensor data logger (contact us if
required) and an optional dyno machine to fine-tune the engine and modify the cells in the fuel tuning
map. Ride the bike/scooter with the data logger as the final feedback for tuning. You may get your best
performance for your engine.

3.6
Setting for ECU Fuel Injection Mode
Rich Fi ECU has built-in an intelligent algorithm to detect the crankshaft flywheel type
automatically. Usually, most crankshaft flywheel types can be detected correctly. However, if one
factory announces a new bike/scooter model with a whole new flywheel that Rich Fi ECU can not
recognize, Rich Fi ECU will simply use the factory ECU’s fuel injection signal to calculate RPM.
Consequently, users must tell Rich Fi ECU which injection mode is adopted by the factory ECU. In
general, most fuel injection bikes/scooters adopt the single-injection within 4-stroke cycle mode, i.e.,
fuel is injected once every two engine revolutions (one 4-stroke cycle). Few bikes/scooters adopt the
double-injection within 4-stroke cycle mode (one injection per engine revolution). User can set the ECU
fuel injection mode as shown in Figure 3-10.
Figure 3-10 Setting for ECU Fuel Injection Mode
If the setting is wrong, Rich Fi ECU will read wrong engine revolution. If user cannot make sure
what is adopted by his/her bike’s/scooter’s ECU, just upload the fuel map with the default “1X Injection
/ 4T” and start the engine to see whether the idle RPM reading is correct or not. If the idle RPM reading
is wrong (usually you may see either half or double RPM reading), you just choose another option and
upload the fuel map again.
