This is a six-in-one gauge-type UEGO controller.

AEM’s Gauge-Type Wideband UEGO Controller features an LED readout 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.

No laptop required for monitoring!

Key features of the AEM Gauge-Type UEGO Controller:

* 24 Color-coded LED display lights provide immediate reference to engine’s air/fuel ratio (AFR) or Lambda (11.0:1 to 17.0:1)

* Integrated three-digit display reveals AFR or Lambda in real time (10.0:1 to 18.5:1)

* User-selectable 0-5v analog output included for use with data loggers and most programmable engine management systems

* Switch between AFR or Lambda readout with a twist of a switch (included face plate change is required for proper readout)

* Included black and silver bezels, black and white AFR gauge faces and black Lambda gauge face allow you to personalize the look of your gauge!

* Quick-Connect system eases installation by allowing users to mount the gauge and sensor wiring separately

* Ideal AFR monitoring tool for carbureted applications and engine dynamometers

* Does not oscillate AFR like narrow band sensors

* Serial data stream included for output of AFR (RS 232)

* Accurate to 0.1 AFR

* Bosch UEGO sensor included
