Monitor Performance: iDash Wideband O2 AFR Module
The new Banks Wideband O2 Air-Fuel Ratio (AFR) Module is an advanced sensor system designed to integrate into the iDash information ecosystem and accurately measure air-fuel ratio. It provides precise, real-time data, allowing for optimized engine performance, improved fuel efficiency, and reduced emissions. Data from the Wideband O2 Air/Fuel Ratio (AFR) Module can be monitored in real-time with any iDash, and when coupled with the iDash DataMonster or forthcoming iDash Data Pro, can be recorded along with other engine parameters. Data can be played back on the iDash or exported for deeper analysis using our free website datalogviewer.com or any data analysis tool.

Compatible with various fuels, including gasoline, diesel, ethanol, and methanol, the Banks Wideband O2 AFR Module is an essential tool for tuning or engine development.
The Science of Air-Fuel Ratio Monitoring
Precise air-fuel ratio tracking is critical for safe engine tuning. By measuring exact oxygen concentrations in the exhaust stream, the wideband O2 sensor provides the iDash with high-resolution data to prevent lean-out conditions, optimize combustion efficiency, and maximize safe power output.
