Accurate Air/Fuel Ratio data is critical when tuning an engine.

Running rich can cause a loss in power, while running too lean may result in serious engine damage.

The AEM Wideband O2 UEGO Gauge features large LED numerals which enable you to see when there’s even a .1 change in ratio, giving you time to shut things down before damage occurs.

The Bosch 4.2LSU sensor, which gives the controller its speed and accuracy, is laboratory calibrated at the factory and never requires free air calibration when used with an AEM Controller.
