FuelTech NANO PRO O2 Conditioners Owner’s Manual
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 confi 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 confi gure the Bosch LSU Sensor type.

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 fi ne tuning.
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
Bosch LSU 4.2 Wideband 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 (infi 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 WBO2 Nano automatically calibrates the sensor.
Part Number Bosch (Brazil): 0 258 007 057 or 0 258 007 351
VW: 021-906-262-B
BOSCH LSU 4.9
The Bosch LSU 4.9 O2 sensor works the same as the 4.2
Part Number Bosch (Brazil): 0 258 017 025
BOSCH LSU 5.2
The O2 sensor Bosch LSU 5.2.
Part Number Bosch (Brazil): 1 928 404 719
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.
NTK
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.
Part Number FuelTech: 5005100011
Free-air calibration
The NTK O2 sensor needs an open air calibration, so after confi guring in the software it is necessary to connect the sensor to the Nano PRO and carry out the calibration.
To perform this procedure, fi 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.
O2 Sensor Installation
The sensor must be inserted in the exhaust system with its tip exposed to the exhaust gas flow. 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 inflow of air, resulting in incorrect readings.
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.
Configuration through the Nano PRO Interface
It is possible to confi gure the FuelTech Nano PRO entirely from the screen. Below are a few example screens.

Confi gure here the screen that will be the main dash, presented on startup of the Nano PRO. You can choose the total number of Dashboards, for that, click on one of the 3 free spaces.
Wideband Meter
There are two possibilities for viewing the O2 sensor value.
Ideal range bar: In this option, the O2 sensor value will be shown on the
display and just below a bar with the ideal range of air/fuel mixture.
NOTE
To display a bigger O2 value on the display, do not confi gure the ideal range
values.
Value only: in this option the O2 sensor value will be very similar to
the WB-O2 Nano. Only the O2 sensor value will be displayed.
In this case, it is possible to confi gure the color of the value shown on the
display.
Available colors: White, Blue, Green, Yellow, red and Orange.
Select which will be the Nano PRO’s main dash screen. It’s possible to confi gure any of five screens as the main screen.
Data gauge
Select which data will be displayed in each dash. It is possible to confi gure up to 3 parts of information per screen with different sizes and positions.
If necessary, also confi gure the minimum and maximum values for each confi
gured information. These alerts are displayed on the Nano PRO screen and are
independent of the ECU, and may be different values from those confi gured in
each module.
Button
Select which buttons will be triggered in each dash. It is possible to confi
gure up to 2 buttons per screen.
After each confi guration it is necessary to go to the last screen and click
on the save button.
IMPORTANT
Buttons to work correctly, it is necessary to confi gure the inputs in the ECU
map in the FTManager software.
NOTE
When the screen remains idling with no input from the user for longer than 10
seconds, the action is canceled and the interface returns to the main screen.
Display configuration
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 fi rst installation and whenever you
notice difficulty in touching the screen.
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.
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 startthe heating in
automatic mode (whenever it is turned on), by temperature or RPM.
Limited: Limits heating current to 2, 2.5, and 3 Amps
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.
O2 sensor configuration
Select the model of the O2 sensor installed in the car. On the next screen
confi gure the installation position.
The next step is to defi ne the unit, fuel type and also the working scale
(analog output
Procedure for replacing the Lambda O2-sensor
Perform the procedures described below to change the probe:
a – Disconnect the old O2 sensor and remove it.
b – Change the confi guration for the new O2 sensor on the Nano PRO.
c – Turn off the module.
d – Connect the new O2 sensor.
