Wideband O₂ AFR Module | Precision Tuning Data

Banks Wideband O2 AFR Module connected to an iDash data system

“Precision tuning starts with accurate data. The iDash Data Pro with the Banks Wideband O₂ AFR Module gives you both.” — Gale Banks

The Banks Wideband O₂ AFR Module is the missing link for anyone serious about precision tuning. By accurately measuring your engine’s real-time air/fuel ratio, it eliminates the guesswork that often comes with traditional O₂ sensors. 

Data done correctly:

  • Accurate monitoring: Measures real-time air/fuel ratio for precise tuning and peak engine performance.
  • Smart integration: Seamlessly connects to the iDash sensor ecosystem—view live data or record it with the iDash Data Pro.
  • Tuner’s edge: Log, analyze, and refines your setup using the Banks DataLog Viewer for pro-level calibration.
  • Confidence, not guesswork: A wideband O₂ turns “it feels right” into data-driven certainty.

Why Wideband AFR Data Matters

Air/fuel ratio is one of the most useful measurements for understanding how an engine is operating under load. Instead of relying on feel or indirect signals, a wideband AFR module provides real-time data that can be viewed through a compatible iDash system and recorded for later review.

That information helps tuners compare changes, identify trends, and make decisions based on measured engine behavior. It is especially valuable when testing different calibrations, boost levels, fuel strategies, or operating conditions.

The Banks Wideband O₂ AFR Module is designed to work within the Banks iDash sensor ecosystem. Review the Wideband O₂ installation manual before installation, and learn more about the related Banks Wideband AFR Module.
