AEM Wideband UEGO controller monitors air/fuel ratios during tuning to prevent lean fuel mixtures that can lead to engine damage. This unit combines AEM's single-channel wideband UEGO controller and gauge display into one compact unit. This gauge type controller features a digital LED display and sweeping LED needle that changes colors as the AFR changes from rich to lean. The gauge fits in any 52mm (2 1/16") housing and can be mounted virtually anywhere in the cabin. Some of the key features are:

  • AFR monitoring tool for EFI and carbureted applications and engine dynometers.
  • No laptop required for monitoring
  • Includes Bosch O2 Sensor
  • Accurate to 0.1 AFR
  • Capable of reading in AFR or Lambda with a flick of a switch
  • 24 Color Coded LED display lights for immediate reference to engine's AFR or Lambda ratio
  • Integrated three-digit display shows AFR or Lambda in real time
  • Serial data stream included for output of AFR (RS 232)
  • User programmable 0-5v analog output included for use with data loggers or any engine management system
