What is a wideband UEGO Sensor?
UEGO is an acronym for Universal Exhaust Gas Oxygen sensor. It is the most accurate, fastest responding type of Air/Fuel Ratio (AFR) sensor available on the market today. UEGO sensors should not be confused with common “switch” type O2 sensors equipped in OEM vehicles that are designed to work within the parameters of a factory engine management calibration.
Why do I need a wideband UEGO AFR sensor controller?
If you are going to modify your engine in any way, knowing the Air/Fuel Ratio (AFR) is critical to achieve the best performance, and to prevent leaning out and potentially destroying the motor.
I saw an O2 gauge online for $80, isn't this the same thing?
NO! The vast majority of O2 sensors are of a simple "switch" type. These sensors can only indicate whether your engine is running rich or lean, but not what your actual AFR reading is. For tuning purposes, these types are sensors are useless.
I have an aftermarket fuel injection computer. Can I use the AEM UEGO Controller Module or Gauge-Type UEGO Controller with it?
Yes. It has a 0-5v output so you can simply hook up the UEGO module to the O2 sensor input wire of your fuel injection computer.
I have a four-cylinder car. Which AEM wideband UEGO Controller should I use?
You can use our single-channel controller module or single-channel Gauge-Type controller module. If you elect to use the controller module and wish to view your AFR in real time, you will need to purchase an AEM UEGO digital display gauge, or monitor AFR from your laptop if you have a stand-alone engine management system that has this capability.
I have a V6, V8, V10 or V12 car. Which AEM wideband UEGO Controller should I use?
You can use our dual-channel controller module or two single-channel Gauge-Type controllers if you want to monitor both cylinder banks. We supply AEM digital display gauges if you want to view your AFR in real time and elect to use our dual-channel wideband controller.
Do I still need to run my factory exhaust gas sensor if I have an AEM wideband UEGO controller?
Maybe. If your vehicles Engine Management System uses the O2 sensor for fuel control and you cannot recalibrate it for this different sensor signal, then you will need to retain the factory sensor. If you are running a factory ECU then you will need to continue to send it the factory narrow-band signal or it will throw a Check Engine Light (CEL). Additionally, on emission controlled vehicles in California you MUST retain the unmolested stock emission system for emissions legality.
Will my nitrous oxide system damage the wideband UEGO sensor?
Nitrous Oxide itself is not in any way harmful to a UEGO sensor. However, running excessively rich will shorten the sensors expected life and many nitrous systems run in this condition “out of the box” and can shorten the sensor’s lifespan.
