Wideband Controllers & Sensors

Wideband/Air-Fuel sensors perform the same function as a regular O2 sensor, but they precisely measure the amount oxygen in the exhaust rather than just switching between rich (too much fuel, not enough oxygen) and lean (too much oxygen, not enough fuel). A wideband controller and sensor is highly recommend when tuning any engine.
