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.
This exclusive remedy shall not be deemed to have failed of its essential purpose so long as FUELTECH is willing and able to repair or replace defective goods.
AFR Ethanol (1.89 - 89.9) • Dimensions: 2.64” x 1.83” x 1.48” (in) 1.48 in 4.1 Package contents • Nano PRO module • Instructions manual • 4 screws for fixation IMPORTANT Installation MUST use the screws that come with the product. Out of specification screws...
5. Nano PRO Electrical Installation The Nano PRO has a 12-way connector with 3 wire groups. One of them has the connector for the O2 sensor, the second makes the CAN communication with Power FT ECU’s and the third is responsible for power and analog output.
5.1 Adapter harnesses The harness of the Nano PRO is the same as the WB-O2 NANO and is prepared for connection with a BOSCH LSU 4.2 sensor. To use other conditioners, it is necessary to purchase the specific harnesses for each one of them. It is also possible to buy just the connector kits to replace the LSU 4.2 plug with another one.
5.2 Replacement of Bosch LSU sensor connector 4.2 for 5.2 This procedure is necessary if you want to use a Bosch LSU 5.2 sensor in a Bosch LSU 4.2 Sensor harness. Refer to table below for sensor pinout: Connector Nano PRO Connector Bosch LSU Connector Bosch LSU Function wire sensor 4.2 (Pin)
5.3 Replacement of Bosch LSU sensor connector 4.2 for NTK This procedure is necessary if you want to use a NTK sensor in a Bosch LSU 4.2 Sensor harness. Refer to table below for sensor pinout: Connector Nano PRO Connector Bosch LSU Function wire sensor Connector NTK Sensor 4.2 (Pin)
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”...
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.
NANO PRO 8. Confi guration 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. O2 sensor with a data Single O2 sensor gauge Single O2 sensor gauge Three data fi...
PRO Switching between modes can be activated by a button If necessary, also confi gure the minimum and maximum values on the Nano PRO screen or come directly from the ECU via the for each confi gured information. These alerts are displayed on FTCAN 2.0 network.

This menu shows the O2 sensor usage time and the average heating time, as well as the hardware, software and serial number of the Nano PRO. It is also possible to reset the O2 sensor usage time by clicking on the “Reset” button.
To confi gure the Nano PRO through the FTManager software, follow the steps described below: a - Open the map in FTManager Software b - Access the “Tools” menu and then click on “External Modules” and locate “Nano PRO and open the confi guration screen.
Nano PRO allows the selection of the display unit and O2 sensor reading scale, but, these settings are read from the Power FT ECU’s during its initialization. In case it is removed from the CAN network, Nano PRO goes back to factory confi guration.
- Open the “Tools” tab and click on the button “CAN Updater” (2); e - A screen for updating the Nano PRO Software will open. On the left (3) of the screen will appear all the equipment available on the CAN network. Select which Nano PRO will be updated.
