Product Description

A wideband UEGO sensor controller accurately monitors Air/Fuel ratios (AFR) during the tuning process to prevent a lean fuel mixture, which could lead to engine damage. AEM has combined its single-channel wideband UEGO controller and gauge display into one unit, uniting unsurpassed AFR accuracy and control with an easy-to-read interface. AEM’s Gauge-Type Wideband UEGO Controller features a digital LED display and sweeping LED “needle” that changes colors as AFR changes from rich to lean. The unit’s 52mm (2-1/16”) gauge housing fits in most gauge pods and can be remotely mounted virtually anywhere.

  • Ideal AFR monitoring tool for EFI and carbureted applications, and engine dynamometers
  • Does not oscillate AFR reading like narrow band sensors
  • No laptop required for monitoring!
  • Bosch sensor included
  • Accurate to 0.1 AFR
  • Reads in AFR or Lambda via a switch in back of gauge housing
  • 24 Color-coded LED display lights provide immediate reference to engine’s air/fuel ratio (AFR) or Lambda ratio
  • Integrated three-digit display reveals AFR or Lambda in real time
  • User-programmable 0-5v analog output included for use with data loggers and virtually any engine management system
  • Serial data stream included for output of AFR (RS 232)

Product Reviews

Hands down the best and cheapest wideband sensor controller on the market, Wednesday, June 24, 2009

In my opnion the AEM UEGO 30-4100 is the best and cheapest wideband sensor controller on the market. It allows for fine tunning of all fuel settings and really give the tuner amazing control over the vehicle. The Bosch sensor the 30-4100 comes with is what really makes this wideband controller incredible as it allows for precise measurement.
