2. Presentation
FuelTech Nano PRO is a tool used for monitoring and datalogging of air to fuel ratios on combustion engines. The
device is able to read and share with the ECU the following oxygen sensors: BOSCH LSU 4.2 / BOSCH LSU 4.9 /
BOSCH 5.2 and NTK wide-band sensor.
Besides it’s multiple types of O2 sensors compatibility, the Nano PRO is also a dashboard, allowing the con guration
of up to 5 screens to display information sent by the ECU (FTCAN 2.0), or work as button to activate various ECU
functions.
Monitor the engine’s air/fuel mixture and explore the complementary features, displaying complementary info or
saving inputs by activating buttons thought it’s screen.
The new Nano PRO is fully compatible with the WB-O2 NANO harness, sharing same connector and pinout.
When stand-alone, the display will only show the air/fuel mix information.
Bosch sensors are self-calibrating, while NTK sensors require an air free calibration, see the manual for information
about the procedure.
IMPORTANT
After the Bosch LSU sensor is installed make sure you select the correct sensor. This will
prevent sensor damage and reading errors.
There are differences between AFR (air fuel ratio) from the Bosch LSU Sensor 4.2 and 4.9, so it’s necessary to
correctly con gure the Bosch LSU Sensor type.

6. Wide Band O2 Sensor
Better known as the oxygen sensor, it is responsible for reading
the exhaust air/fuel ratio. This sensor is essential for engine
 ne tuning.

6.3 BOSCH LSU 5.2 O2 Sensor
The O2 sensor Bosch LSU 5.2.
6.4 NTK O2 Sensor
This O2 sensor is used in engine laboratories, due to its extreme
accuracy and speed in reading in different AFRs.
This O2 sensor requires an free-air calibration.
Free-air calibration
The NTK O2 sensor needs an open air calibration, so after
con guring in the software it is necessary to connect the sensor
to the Nano PRO and carry out the calibration.
To perform this procedure,  rst connect the O2 sensor to the
Nano PRO and leave it out of the exhaust. Turn the ignition on,
and let the NTK O2 sensor heat up for 5 minutes, then access
the sensor setup menu, select NTK, and click on the “calibrate”
button.
The calibration process is executed 5 times to guarantee the
expected result, after the test a message with the result will
appear on the screen. If an error message is displayed, it is
necessary to repeat the calibration procedure.
IMPORTANT
Bosch LSU oxygen sensors are not designed to
run on fuel that contains lead, and their lifespan
is drastically reduced to around 50 to 500 hours.
Part Number Bosch (Brazil): 0 258 017 025
Part Number Bosch (Brazil): 1 928 404 719
Part Number FuelTech: 5005100011
6.1 BOSCH LSU 4.2 O2 Sensor
Bosch LSU 4.2 sensor has an encased heating element and it is
used to measure the air fuel ratio, which determines the lambda
value in the remaining exhaust gas. Its signal indications vary
from 5.14AFR Gas (0,35λ)lambda (rich mixture) to open air
lambda (in nite).
The connector includes a calibration resistor (factory calibrated),
which defines the characteristics of the sensor and it is
necessary for its operation. It is with this resistor that the WB-
O2 Nano automatically calibrates the sensor.
NOTE
Running the engine with the sensor installed to the
exhaust and not connected to the Nano PRO (or
other conditioner) may damage the sensor.

NANO PRO
11
6.5 O2 Sensor Installation
The sensor must be inserted in the exhaust system with its tip exposed to the exhaust gas ow. It must stay in an
angle between 10 to 80 degrees to horizontal position, that is, with its end downward, in such a way that steam
droplets cannot be accumulated between the body of the sensor and its ceramic part, which could cause damage
when the sensor is used. The sensor must not be placed vertically, as it becomes subject to excessive heat.
It is recommended that the sensor is installed at least one (1) meter away from the exhaust manifold to avoid
excessive heat, and at least one (1) meter away from the exhaust external output to avoid incorrect readings caused
by oxygen in the air outside the exhaust system.
Notice that such recommendations are not obligatory, as vehicles with a smaller exhaust system will need to have
the sensor placed closer to the engine.
The sensor must stay away from the cylinder head and from areas where one cylinder might affect the exhaust air
more than the others must. Avoid placing the sensor close to the exhaust manifold joints, as some allow the inow
of air, resulting in incorrect readings.
7. CAN Communication
The Nano PRO has CAN communication, which allows the module to send and read information from the Power FT
ECU’s that are also connected in the network. Included on the Nano harness are two 4-way CAN connectors that
plug and play with other Nano PRO units as well as the Power FT ECU’s.
When connected to the CAN port, the Nano PRO can read what the fuel and the measurement unit (lambda or AFR)
that the ECU is set, adjusting itself to these settings, disabling the analog output and sending the AFR value to ECU
in the range of 2.94 to 149.9 AFR Gas.
In the CAN network, during the O2 sensor heating period, the value displayed in the Power FT ECU’s will be equal
to 0 (zero) and the back of lambda gauge will turn yellow.
In case of any error during work, in addition to the warning on Nano PRO display, the error will be sent via CAN to
the Power FT ECU’s and recorded in “Status Events” log.
To connect the Nano PRO via CAN to Power FT ECU’s simply plug the 4-way cable to the ECU CAN port.

8.2 Display con guration
In this menu you can choose the screen lighting in day and night
modes. These values are independent of the ECU, that is, the
day and night values can be different between ECU and Nano
PRO Switching between modes can be activated by a button
on the Nano PRO screen or come directly from the ECU via the
FTCAN 2.0 network.
After lighting setup, the display calibration screen will appear.
It is recommended that it be done on the  rst installation and
whenever you notice dif culty in touching the screen.
8.3 Heating setup
O2 sensor heating is essential for starting the lambda sensor
reading. On the Nano PRO there are 3 heating modes:
Normal: Standard heating currently used by the WB-O2 Nano.
This is the recommended mode for FuelTech ensuring a longer
O2 sensor life.
It is possible to choose one of the three parameters to start
the heating in automatic mode (whenever it is turned on), by
temperature or RPM.
Data gauge
Select which data will be displayed in each dash. It is possible
to con gure up to 3 parts of information per screen with different

If necessary, also con gure the minimum and maximum values
for each con gured information. These alerts are displayed on
the Nano PRO screen and are independent of the ECU, and
may be different values from those con gured in each module.
IMPORTANT
Buttons to work correctly, it is necessary to
con gure the inputs in the ECU map in the
FTManager software.
Fast heating, uses a high current to shorten the heating time. By
using this option the O2 sensor life will be drastically reduced.
It is possible to choose one of the three parameters to start
the heating in automatic mode (whenever it is turned on), by
temperature or RPM.

When there is an output reading error, the analog output locks
at 0.00V. Thus, it is possible to know if there is any problem
or error in the equipment. To congure this output on external
equipment, it is necessary to supply the rst and last values of
the table above.

12. Nano PRO Codes
12.1 Informative Codes
When turning Nano PRO power on, the following information will be displayed:
Product name
Measurement unit (Lambda, AFR gasoline, AFR alcohol or AFR Methanol)
Analog output scale (as seen on chapter 6)
Cylinder identi cation (when connected via CAN with Power FT ECU’s): tells which cylinder the conditioner is reading,
when used for individual cylinder adjustment.
Then the word HEATING indicates the O2 sensor heating for operation.
After heated, the word HI appears when AFR above 146.9 AFR Gas (64.1 AFR Alcohol) is read.
12.2 Error Codes
VCC = 12V Power / GND = Ground
