NANO PRO

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.
