I target 11.5:1 because of the supercharger and I see varying narrow band O2 mV anywhere from 900 to 1000. Part # 350-34081. Check if this fits your 2016 Hyundai Elantra. You can use the following procedure to narrow down which wire is which: Stick straight pins into the sensor's wires and measure them to ground with the engine running. Besides the TYPE of oxygen sensor, many different part numbers ARE THE SAME except for the pigtail and wire length. I collected a lot of part throttle data with the LC-1 Wideband vs. the Stock O2 Sensor AFR (I also graphed boost). Those three things are whether the mixture is Rich, Stoich or Lean. The X-Axis is time. While a narrowband sensor operates in the 600 F range, a wideband sensor needs to be heated to 1,200-1,400 F. The fast heating helps reduce emissions during cold starts and allows for improved fuel efficiency because the engine spends less time operating in open-loop mode. The control box SHOULD (I've never used a PLX) have some sort of 5V output wiring to go to your ecu. They send voltage to the ECU on a scale of 1 to 5 so that it knows exactly what is required to maintain target air/fuel ratios. A wideband oxygen sensor (commonly referred to as a wideband O2 sensor) is a sensor that measures the ratio of oxygen to fuel vapor in the exhaust exiting an engine. since it has a larger voltage range it offers a much higher . The right Y-Axis is Boost (psi). Coasting downhill is . Next find any wires that produce 0 volts. We won't get into all the details of how this . Narrowband vs. Wideband A narrowband O2 sensor only informs the computer if your engine is running rich or lean. A narrow band sensor is basicly a sensore that is able to realiable sense air to fuel ratio but on a very narrow band, IE and can only realiably tell you around stoich what the air to fuel actually is. For gas this ratio is 14.7 to 1, but this air fuel ratio is not ideal for all applications. A wideband O2 sensor is much more sophisticated and can supply the exact AFR measurement across a wide range of possible AFR values. Only a wideband o2 sensor and controller can give you accurate feedback outside of the stoichiometric 14.7:1 reading that NB sensors are designed for, and allow you to tune for best power and best economy. Simon0721 said: Unlike US, Euro models (and I belive AU models too) gen 4 came with O2 sensor, so the link pipe had the bung to install the stock sensor. I'd like to get some inputs on wide-band O2 sensors for the R1150RT. Here are a couple of videos that show a comparison between an Innovate LM2 and a narrowband sensor display. Then you'll cut the wire coming out of the D14 pin of the ECU and solder the output wire from the gauge to it. Wideband o2 vs narrowband. Wideband o2 sensor versus narrowband o2 - what's the difference? If you don't make use of the oxygen pump, a wideband sensor won't differ from a narrowband one. To summarize, a narrow band O2 sensor is only able to tell a computer (or gauge, for that matter) whether an engine is operating above or below a 14.7:1 air/fuel ratio. This also helps your ECU stay more accurate over time with smooth changes instead of the over corrections that narrowband sensors require. Wideband sensors not only are a lot faster acting in the reading, but can tell you the exact a/f ratio that the motor is currently at. If you are still not sure, you can use an oscilloscope to actually measure the analog outputs of different wideband controllers if you really want to see the difference. bnichols04. A wideband O2 sensors output is 0-5 volts whereas the standard O2 sensor is in the 0-1.2 volt range. Another difference is that A/F sensors don't produce a voltage signal that suddenly changes on either side of Lambda when the air/fuel goes rich or lean. The experimental work procedure is illustrated in Fig. GM typically uses narrow band O2 sensors. ThunderMax uses Wideband O2 Sensors to get the most from your bike. You can however, wire one of the analog 5V outputs from a wideband controller into the factory ECU using Cobb's custom features. USA There are wideband controllers (like the Innovate LC-2) that have two outputs. In a nut shell, a wide band give the ecm 3 reaponses, ok, rich, or lean, and the ecm changes according. Nah, untuk memantau atau mengukur AFR di motor injeksi, diperlukan yang namanya sensor oxygen (O2 . It's not possible to replace it with a wideband. there are some aftermarket efi systems that use them for tuning the system to the engine. PRICE: 91.49. That is all. Accurately reads the air/fuel ratio of any internal combustion from 0.68 Lambda to 1.36 Lambda (10:1 - 20:1 AFR *Gasoline). The controller costs almost as much as the sensor. The wideband controller (SM-AFR) works with gasoline, bio diesel, ethanol, methanol, E85, LPG, and CNG. In the '06 service manual, section EC, page 288 it states that the heated O2 sensor (narrowband, loacted after the cat): QUOTE. 2 x NTK Sensors. Narrowband o2 sensors, which is what the AP uses, are only built to determine 3 things. In short, not only the sensor LSU 4.9 is superior to 4.2; but also the controller with a CJ125 chip makes it an OE equivalent system. 14.7:1). A wideband o2 sensor is much more sophisticated than a narrowband sensor, and can be relied upon to be used as a tuning tool. The factory narrow band sensors work with the factory ECU. Standard narrow band type Oxygen Sensors operate between 0 and 1 volts, and are only capable of accurately measuring a stoichiometric air/fuel ratio (e.g. The biggest thing the wideband is used for is in tuning your engine. With a 0-1v output, steady state stochiometric is seen by the ECM as a rapidly and evenly alternating lean-rich cycle. So that's not an issue since the B1 sensors are close to each other and we also have a narrowband and a wideband in stock manifolds and in the stock positions. They only tell you if you are above (leaner) or below (richer) than commanded lambda (AFR). You'll need to retain the factory narrowband. Sensor Type: Narrow-Band. A wideband o2 sensor system will give you far greater tuning ability than a narrowband o2 sensor. A narrowband sensor can really only quantify between 0.99-1.01 , or like 14.6-14.8 gasoline AFR. The stock powertrain has spent enough time on FHI's dyno's to handle itself. Wide Band O2 Sensors where developed in the early '90s as vehicle manufacturers began looking to obtain air/fuel ratio information under all circumstances. All O2 sensors are narrowband sensors. 1 x Haltech DTM4 to DTM4 CAN Cable (4'/1200mm) 1 x DTM-4 Power Supply Cable (6/150mm) 2 x NTK to DTM 6 Adaptors (1200mm) 2 x Stainless Steel Bungs. on a stock ECU the wideband O2 will not work IIRC. The wideband air/fuel ratio sensor combines an oxygen-sensing "Nernst" cell from the narrow band sensor with an "oxygen pump" to create a device that gives a wide range response to various air/fuel ratios. SM-AFR - Wideband Air/Fuel Sensor Module. Read More. You have a RICH AFR (<14.7) Lean could mean 14.8 or 19. The challenge with a narrowband sensor is that it is only truly accurate at 14.7:1 AFR (the stoichiometric air/fuel ratio for gasoline). In a normal car this is considered ideal conditions for clean . No difference in better or worse. Includes: 1 x Dual Channel Haltech WB2 Controller. yes, you will find the wide band o2 sensors used mostly in the dyno testing arena. A narrow band O2 sensor can only correctly measure the stoichometric air fuel ratio. The Nernst cell senses exhaust gas oxygen in the same as a conventional narrow band O 2 sensor. In short, a wideband oxygen sensor will give you a measurement of your Air/Fuel Ratio from about 10:1 up to about 20:1 AFR allowing you to target exactly the AFR you're after at all times. It includes two analog outputs (wideband 0-5V, and narrowband 0-1V) for interfacing with 3rd . The oxygen sensor, or 02 sensor, measures the amount of oxygen in your vehicle's exhaust gases. Thread in ' Technical Questions ' started by oscar, Feb 15, 2014 . Aug 2, 2016. the voltage response to a given O2 level would have to be the same as th stock one. 1. They don't tell you what the actual AFR is. Download : Download high-res image (153KB) Download : Download full-size image; Fig. Wideband oxygen sensors, commonly referred to as air-fuel ratio sensors, tell the ECU how rich or lean the engine is running in comparison with stoichiometric ratio. The measured ratio is expressed as parts of oxygen to fuel. Accuracy vs. Wideband gauge used in. Narrowband oxygen sensors inform the ECU whether the engine is running lean or rich with reference to the stoichiometric air/fuel ratio (14.7/1). "Even if switching characteristics of the [wideband] air fuel ratio (A/F) sensor 1 are shifted, the air-fuel ratio is controlled to stoichiometic, by the signal from the [narrowband] heated oxygen sensor 2." Granted its a little more complicated then this but. You can order these from a VW or Audi dealer. SKU # 924808. The advantage of wideband is the capability to . The benefit of using a narrow channel is the lower noise bandwidth and hence better sensitivity and range. A wideband O2 sensor has an output from 0-5V, a big part of the whole "wideband" thing. A wideband sensor measures how rich or. 17 graphs in this directory that clearly illustrate how inaccurate the stock O2 sensor is. This however, is new to me: "The best way to determine your own switch point is to datalog the wideband kit while running closed loop off a stock narrowband sensor and then simply take an average of the raw wideband voltage (available in the datalog as a Raw value) while the narrowband sensor is cycling normally." Both sensors have their place in tuning an engine, narrowband sensors are designed to be used in conjunction with a catalytic converter. As I understand it, under cruise conditions, constant TPS and roughly constant RPM, the Motronic 2.4 goes into Closed Loop operation, cycling between slightly rich and slightly lean with the engine running with an average AFR (air fuel ratio) of 14.7 to 1 as set by the narrow band O2 sensor and Motronic. A conventional O2 sensor will produce either a rich reading (0.8 volts) or a lean reading (0.2 volts) when the fuel mixture changes. As we mentioned earlier, O 2 sensors use free oxygen as the basis for a calculation of an AFR. Stoich is I beleive 14.7 to 1 meaning for every 1 part fuel you have 14.7 air. A common definition (ETSI) of narrowband is when 25 kHz or less is used for the radio channel. Wideband vs Narrowband o2 sensor. A wideband oxygen sensor is very accurate when at operating temperature and has a 0-5 volt output range, which the gauge will convert to a value ranging from 10.0:1-19.0:1. What is an 02 Sensor what does it do? The wideband will actually measure specific AFR which is need for tuning. only problem with using the output to make changes is that there will be only one wideband install on an engine. Narrow band vs Wideband o2 sensor comparison is explained. The bigger part of the wideband thing is the actual range of AFR's that a wideband is accurate over. That's why it's called a narrow band, because it has a narrow window of what it can do. This gives you the ability to datalog the wideband from the Accessport. Wideband ECU Solder (60/40) & soldering iron New o2 harness Wideband o2 sensor wire & wire cutters heat shrink tubing 15ohm 25 watt resistor and ECU pin picks and various other tools such as a 7/8 wrench for the o2 sensors First you will need your new o2 harness. Bosch Reverse Engineer Oxygen Sensors Biasanya untuk dapat tenaga maksimal, AFR disetel 12,8 - 13,0 : 1. So trying to tune for 12.5:1 by trying to get your narrow band O2s to 1V is not going to work. What I'd like to do is install a wideband into the stock front 02 sensor location and have it simulate a narrowband 02 signal to the ECM and send a wideband signal to my gauge. That narrowband sensor can again only tell you 'you are leaner than 14.7:1 but I don't know by how much'. On a boosted car, you could be dangerously lean, while the narrowband is showing you youre rich. Operating temperature, wire connections, out put differences and construction of both the sensors is discussed with the help of animation. the first one had the number 016 and .
