Narrowband Vs. Wideband o2 Sensors (Air Fuel Ratio Flow Meter)
Additionally, you will get units costing 1000 dollars to $ 4500 dollars per installation and in some cases more. Most are wide band units. In case you are a contractor or tuner of efficiency car engines who wants to increase efficiency of the car engines you use, then you should be computing Air-to-Fuel relative amount using a wide band meter. In case you just need a sign that you are loaded or empty to ensure you would not burn up the engine up, you can obtain a Narrow-Band band flow meter.
How the Traditional 02 sensor Works:
The o2 sensor lets the computer system notice if the vehicle engine is operating higher than or under 14.7:1 by transmitting electric current to the computer system in the range (0 and 1 volts) often changing between the two values of the voltmeter scale. Most of the traditional Narrow Band Air-to-Fuel percentage indicators are just a voltmeter or ammeter for this transmission. You can see the repetitive sweeping backward and forward of the sensor for most stagnant, light accelerator, as well as cruise speeds. To sum it up, a Narrow-Band band Oxygen sensor is just able to notify a computer system (or sensor, for instance) if a car engine is running over or under a 14.7:1 Air-to-Fuel relative amount.
How Modern Wide Band o2 sensors Work:
Honda and Volkswagen began the production of the Wide Band Oxygen sensors to give precise Air-to-Fuel percentages under these changing conditions. They achieved this by increasing the voltage spectrum whereby responses from the 02 sensor were given and setting up a linear reader that supplied a set voltage that corresponded to a particular Air-to-Fuel percentage.
Top performance car tuners found that Wide Band o2 sensors are very beneficial when precise Air-to-Fuel proportion readings are needed to increase power, dependability, as well as gas mileage on modernized cars.
Adjusting a car engine for optimum power formerly required extended trial and error exercises on a dynamometer. Employing the LM1, accurate AFR measurements enables the operator to properly alter several parameters – such as carburetor jetting, gas injections, turbo gas curves, and so on – without lengthy and costly dyno periods. The meter?s electronic transmission control solution supplies information on precisely how loaded or empty a vehicle engine is performing at any particular load. The LM1′s self-measuring circuit system also makes up for alterations in altitude, temperature, and o 2 sensor condition.
Wide Band o2 sensor features:
? 02 sensor displays Real Air-to-Fuel ratio.
? Accurate indication of ratio for the stoichiometric loaded side, which is precisely where all top performing car engines operate.
? Normally shows Air-to-Fuel relative amount to the two decimal places.
? Helpful for increasing power from racing and various performance car engines.
? Completely temperature balanced.
? Accurate indication of ratio for the stoichiometric loaded side, which is precisely where all top performing car engines operate.
? Bigger price tag.

Narrow Band o2 sensor features:
? O 2 sensor displays warning sign for rich compared to lean.
? Normally has extremely rough indication of ratio for the stoichiometric loaded side where all high performance vehicles work.
? Certain units have only two L.E.D.s for the whole rich spectrum!
? Actually only helpful for ensuring that your car engine is not working on the slim side.
? Normally not temperature balanced, hence the same Air-to-Fuel state in the generator can lead to a signal on the meter which will change based on o2 sensor temperature.
? Low priced.
