This is the AEM Electronics UEGO Wideband Controller 4.9LSU AFR Gauge. Wideband gauges are some of the most overlooked, yet imperative gauges you can have in your car. If your engine is highly modified, or if you plan on modifying your engine, then a wideband gauge is a must for your tuner, and a must for yourself to modify the overall running welfare of your engine.

The UEGO Wideband Controller 4.9LSU AFR Gauge provides extra insurance to your engine because if your AFR readings are outside of the tune or the strike zone, then it will let the driver know to stay off full-throttle conditions and investigate what is causing the changing in readings before any significant engine damage can occur.
