1. Presentation
FuelTech NanoPRO is a tool used for monitoring and datalog 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 NanoPRO 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.
FuelTech NanoPRO allows communicating with the FT300, FT350 and FT400 through the FTCAN 1.0 protocol, transforming
the NanoPRO into an auxiliary dashboard.
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 NanoPRO 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.
The NanoPRO provides the functionality to read original vehicle parameters through the OBD-II diagnostic port in original
vehicles. It is essential to note that this tool is only compatible with the ISO15765-CAN protocol and does not support other
protocols.
To use the NanoPRO with OBD-II, you will need to have the special harness, which includes the OBD connector and a wire
that must be connected to the vehicle’s ignition-switched power source.
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.

5. 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.

The Bosch LSU 4.9 O2 sensor works the same as the 4.2
5.3 Bosch LSU 5.2 O2 sensor
The O2 sensor Bosch LSU 5.2.
5.4 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 NanoPRO
and carry out the calibration.
To perform this procedure, rst connect the O2 sensor to the
NanoPRO 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
5.1 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
denes 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 NanoPRO (or other
conditioner) may damage the sensor.

11
5.5 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.
5.6 O2 sensor for use in Diesel powered vehicles
The NanoPRO allows readings of various fuels including engines fed with oil Diesel as fuel, in this case the recommended
O2 sensor are Bosch LSU 4.2 and 4.9.
For use in Diesel, it is necessary to take some precautions so as not to reduce the useful life of the probe, they are:
• AFR Diesel values between 11.60 and 15.95 are the maximum power for oil Diesel.
• It’s recommended to use AFR Diesel values upper than 18.85 where the exhaust gas temperature is lower.
• Black smoke is an indication of an extremely rich mixture and this particulate will drastically reduce the useful life of the
O2 sensor.

6. OBD-II harness installation
To use the NanoPRO as an OBD-II display, it is necessary to obtain the specic harness for this purpose.

The other pins of the OBD-II port are not used by the NanoPRO.
IMPORTANT
NanoPRO is ONLY compatible with the ISO15765-CAN protocol.

13
7. CAN communication
7.1 FTCAN 2.0
The NanoPRO has CAN communication, which allows the module to send and read information from the PowerFT 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 NanoPRO units as well as the PowerFT ECU’s.
When connected to the CAN port, the NanoPRO 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 PowerFT 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 NanoPRO display, the error will be sent via CAN to the PowerFT
ECU’s and recorded in “Status Events” log.
To connect the NanoPRO via CAN to PowerFT ECU’s simply plug the 4-way cable to the ECU CAN port.

7.2 FTCAN 1.0
FuelTech NanoPRO also features FTCAN 1.0 communication, which allows you to receive information from the old line ECUs
such as FT250, FT300, FT350 and FT400.
To connect the NanoPRO to FT ECU from the old line, it is necessary to use the same communication port as the USB CAN
cable, that is, to use the NanoPRO, it is necessary to disconnect the USB CAN cable from the ECU.
The Lambda sensor reading will still be done by the analog output, being necessary to make the electrical connection of the
ECU with the NanoPRO through pin 5 (yellow/red wire).
The channels sent by the ECU to NanoPRO are as follows: RPM, map, engine temp, air temp, battery, fuel pressure, oil
pressure, tps, point, inj duty A and inj duty B.
IMPORTANT
When using the NanoPRO with an FT250 or FT300 you need to disable the Datalog function.

8.3 Heating setup
O2 sensor heating is essential for starting the lambda sensor reading.
On the NanoPRO 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 start the 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

Free-air calibration - NTK sensor
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 NanoPRO
and carry out the calibration.
To perform this procedure, rst connect the O2 sensor to the
NanoPRO 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.
Possible errors after calibration - NTK sensor
Current highest 4.3 -> faulty sensor
Current below 3.2 -> sensor is not Free-air

time, as well as the hardware, software and serial number of the
NanoPRO. It is also possible to reset the O2 sensor usage time by
clicking on the “Reset” button.
87.8 Settings
In this menu, the CAN communication mode is configured.
FTCAN 1.0: For old line ECUs (FT250, FT300, FT350 and FT400) this
conguration allows you to receive information from the following ECU
channels: RPM, map, engine temp, air temp, battery, fuel pressure,
oil pressure, tps, time , inj duty A and inj duty B.
To display this information, it is necessary to congure the gauges in
section “7.1 Panel conguration” on page 13.
It is also possible to congure a shift alert for FuelTech NanoPRO,
this alert is independent of the ECU.
IMPORTANT
When using the NanoPRO with an FT250 or
FT300 the datalog function is automatically
disabled.
To disable the internal Datalogger follow the steps in the image below.
1 - Click the down button until you locate the internal Datalogger
menu.
2 - Click the button to the right.
3 - Click the down button until the “Internal Log disabled”
information appears.
FTCAN 2.0: This protocol allows communicating with the PowerFT
line modules (FT450, FT500, FT550 and FT600), with this
conguration it is possible to congure buttons to ECU functions on/
off, read EGT sensors,the RPM shift light and Alerts synchronized
with the ECU.
ECU Alerts: These warnings are activated when the condition
congured in the ECU is reached, and will remain active until the
user touches the screen. They will reappear after 10 seconds if the
condition congured in the ECU still persists.

OBD-II: This protocol allows to read the parameters of original cars
through the OBD-II connector with CAN protocol. For the correct
display of the parameters in the NanoPRO it is necessary to congure
the measurement units such as temperature, pressure, speed, and
consumption.
After this conguration is necessary to congure the screens with
the parameters to be displayed, for this see the item "8.1 Panel
Conguration".

Conguration to use NanoPRO out of the CAN network
NanoPRO allows the selection of the display unit and O2 sensor reading scale, but, these settings are read from the PowerFT
ECU’s during its initialization. In case it is removed from the CAN network, NanoPRO goes back to factory conguration.
9.1 Datalogger channels
There are 3 log channels for each O2 sensor tted to the vehicle, which record information about the O2 sensor heating.
With these channels it is possible to have a complete diagnosis, letting you know if the sensor is installed in the correct
position, for example.
Sensor heater PWM: Records the percentage of duty cycle applied to the O2 sensor heater
Sensor temperature: Records the internal temperature of the sensor
Sensor resistance: Records the internal resistance in Ohms of the sensor
