im about to go boosted and i was wondering what wideband actually is im so lost and cofused
thanks
a wide band is a more accurate A/F monitor.
Typical production car O2 sensors rely on “nernst cell” technology, commonly called “Narrow Band”, “2 wire”, “4 wire” and sometimes erroneously described as “Wide Band”. This is a very cost effective method that outputs a voltage based on the oxygen content of the gas being sampled. It is accurate in the region surrounding stoichiometric operation and leaner. Unfortunately, in the rich region where high performance engines usually operate, their accuracy and repeatability is virtually non-existent.
The rich region output of a common O2 sensor is very temperature dependant, which renders it useless if an accuracy greater than 1.5:1 AFR is desired. This is immediately obvious given the fact that a single output voltage actually represents wildly different AFR’s depending on the unregulated and unmeasured sensor temperature. These sensors were designed for operating closed loop around the stoichiometric AFR (14.64 for gasoline), and for performance tuning they are useless.
The heart of the Performance Trends Wideband controller is the Bosch LSU4.2 Universal Exhaust Gas Oxygen (UEGO) sensor. This type of sensor is commonly referred to as “laboratory grade” and works on a different principle than the normal oxygen sensor you would find in your car. Its unique design makes precision AFR measurement possible over the entire operating range.
UEGO type sensors use a “current pump” within the sensor itself to determine the actual oxygen concentration within the sensing element or, lacking any O2, it determines the amount of oxygen required to regain stoichiometric operation. The output is in the form of a very small current which varies depending on the air-fuel ratio. This is completely different from a normal oxygen sensor (1, 2 and 4 wire types) which directly output a voltage. The UEGO design allows measurement of the exact air fuel ratio over the entire operating range.
Each Performance Trends UEGO sensor is individually calibrated and a resistor integral to the connector body is laser trimmed with this value. This process replaces the traditional “free air” calibration procedure when changing sensors and implements a sensor specific calibration for unparalleled accuracy.
I was going to quote you a few times, Fuego, but then I just decided I wouldn't even try it. Too much of a hassle, haha. Good info, though.
Basically, what El Fuego is trying to say is that its a much more accurate tool to measure your A/F ratio. They run at a higher price than narrowband gauges but they're integral to properly tuned and performing boost projects. I purchased an Innovate Motorsports LM-1 wideband kit (with datalogging and software) from CarCustoms. You have a few choices; the ones that I am most familiar with are Innovate Motorsports, Zeitronix, PLX Devices, and AEM UEGO.
Blown.
Zeitronix all the way

thanks alot i just look at car customs website and i will be going with the Innovate Motorsports LM-1 wideband kit also thanks again
Anytime, bro. By the way, get in touch with Karo at CarCustoms and see if he can get you a good price.
Blown.
