DAYTONA TWIN TEC LLC WEGO 3 Air Fuel Ratio Sensor 112005

Tuning your engine without real-time AFR data is like flying blind. The DAYTONA TWIN TEC WEGO 3 gives you precise, accurate air-fuel ratio monitoring—both on the road and on the dyno—so you can dial in your fuel map with confidence and catch lean conditions before they damage your engine. Built-in data logging captures over two hours of AFR, RPM, and sensor information, letting you analyze combustion efficiency and make informed tuning decisions.

Whether you're running a motorcycle, small-displacement engine, or race vehicle without a factory wideband setup, this complete system delivers professional-grade diagnostics in a compact, waterproof package made right here in the U.S.A.
