The WB-O2 NANO w/o Harness is a wideband oxygen sensor interface designed for serious tuners and engine builders who demand precision fuel mapping and real-time air-fuel ratio monitoring. Built by FuelTech USA, this compact sensor module integrates seamlessly into modern engine management systems and aftermarket ECU platforms. Whether you're tuning a turbocharged street build, naturally aspirated performance engine, or full race application, this wideband interface provides the critical feedback needed to optimize combustion efficiency and prevent costly lean-condition damage.
The WB-O2 NANO operates as a standalone wideband oxygen sensor controller, translating raw sensor voltage into a clean, calibrated output signal that your ECU or standalone engine management system can read and act upon. Its compact footprint—measuring just 4.7 x 2.3 x 6.8 inches—allows flexible packaging in tight engine bays without sacrificing durability or sensor accuracy. The harness-free design (w/o Harness) gives installers complete flexibility in routing and termination, accommodating custom wiring schemes and OEM-integration scenarios.
FuelTech's proven signal conditioning ensures stable, noise-free air-fuel ratio data across idle, cruise, and wide-open-throttle conditions. This interface is ideal for tuners working with FuelTech EFI systems, Link ECU, Haltech, or other modern engine management platforms that accept 0–5V analog wideband input. Installation pairs the WB-O2 NANO with Bosch LSU or equivalent wideband sensors for optimal performance.
