If you are running high amounts of boost or if you are using a fuel controller, you will want to install the AEM UEGO. The AEM UEGO monitors your cars air/fuel curve.

24 Color-coded LED display lights provide immediate reference to engines 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
NEW! Switch between AFR or Lambda readout with a twist of a switch (included face plate change is required for proper readout)
NEW! 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!
NEW! 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
