What is a wideband gauge?
Feb 18, 2020 · What is wideband tuning? 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.
Can a wideband O2 sensor be used as a tuning tool?
Using a wideband in on road conditions will enable more accurate fuel tuning. This does not replace dyno tuning, but augments it. Hondata has had extensive tuning time with two wideband lambda meters, the PLX and the FJO. Most wideband meters - (the ones that are of any use in tuning here) have a 0-5 volt output proportional to air fuel ratio.

What is the goal of the wideband?
Aug 15, 2018 · 1. Go for a drive to get the engine good and hot. Don't just go around the block -- go for a 15+ minute cruise around town. 2. When you get back home, hook up vacuum gauge and leave transmission in neutral. 3. Turn all screws out like 1 full turn for a baseline. 4.
Do I need wideband to tune?
If you plan to head to the rollers to get it setup, and want a more hands-off install, then no need for a wideband at all. The dyno operator will use their own wideband during mapping, will optimise the fuelling and ignition, and, everything being equal, it should never change once tuned.Aug 23, 2018
What is a wideband used for?
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. The measured ratio is expressed as parts of oxygen to fuel.
What is the benefit of using a wideband sensor?
A wideband sensor can detect oxygen content in the exhaust that's way below or way above the ideal air/fuel ratio of 14.7:1. More control of new lean-burning engines that emit ultra-low emissions is necessary today.
Can you tune a car without a wideband?
Contrary to popular opinion, you can tune without a wideband. An NB O2 sensor can determine whether or not you're hitting the stoichiometric ratio (14.7). Knowing that, you only have to do basic math to determine how much fuel you need to hit a target ratio. Autotune will do this for you.Sep 22, 2011

Do I need a wideband controller?
without a controller, the wideband sensor is not very useful. The controller also performs other important functions such as heating the sensor, so it gets to it's operational temperature much quicker (compared to waiting for it to heat up due to exhaust gas alone).
Where do I mount my wideband sensor?

Do I need 2 wideband to tune?
It doesn't matter. Think about it, you only have 1 map for both banks. You do have 02s for each bank that adjust both sides, but that is a multiplier based off of one table. Dual widebands would only really matter if you were emulating the narrowbands and keeping them there permanently.Mar 9, 2016
Do you need an O2 sensor to tune?
re: Is it possible to perform Tuning without an O2 sensor? Yes it is necessary for tuning. You don't necessarily need to weld on a bung for it if you don't plan to run a wideband o2 gauge all the time, or enable closed loop. Your tuner can just clamp a sensor in the end of the up pipe for tuning purposes.Jul 24, 2018
Do you need a wideband to tune STI?
Registered. No, The front O2 sensor is wideband.Dec 27, 2010
What is a wideband gauge?
A Wideband allows you to read the exhaust gasses post-combustion. Once you know how much oxygen is remaining in the exhaust, from that you can deduce the A/F of the engine. HOWEVER, the gauge can (WILL) read wrong if you have exhaust leaks before the O2 sensor.
What does "lean" mean on a wideband?
The last very common problem is an ignition problem (ignition miss), which will also show on the wideband as “lean”, as all that O2 goes into the exhaust system. It is critical that you understand that the wideband reads OXYGEN, not fuel! An engine will run pretty easily, even in poor tune.
How many carburetors are in a carburetor?
Really your carburetor is 2 carburetors. 1 for idle and low throttle settings, operating through the idle mixture screw and progression holes. The other is the main circuit, operating through the aux venturi, emulsion tube, main jet and air jet. For now, let’s focus on the idle jet.
What happens if throttle plates are too open?
If the throttle plates are too open (vac at idle) setting idle mixture is difficult, since the engine is also getting fuel from the progression holes, and the idle mixture screw effect can be insignificant. If the plates are not open enough you can get a hesitation off-idle.
What is the A/F ratio?
A/F is the ratio of air to fuel, air/fuel, by mass. Different types of fuel have different ratios that they burn (oxidize) at. Chemically, gasoline works best at 14.7:1 (14.7 parts air to 1 part fuel). Note that this is a CHEMICAL optimization.
Why does my O2 gauge read wrong?
With a leak present, the exhaust will suck in air, and give the O2 sensor a false lean reading. The gauge will also read wrong if you have a mechanical issue with the engine. Examples are a vacuum leak allowing unmetered air into the engine, running lean.
Is gasoline vaporized in an engine?
First, we have to go into the theory of combustion in the engine, and how important good fuel vaporization is. The engine will, in fact, run if you pour gasoline down the air cleaner throat, but this is not good vaporization. Fuel Injection gets the fuel into a nice mist, but note this is still not well vaporized.
Why use wideband gauge?
Using a wideband gauge to keep track of your engine’s air/fuel ratio comes with a range of benefits, including: Wideband gauges are ideal for diagnostic purposes. Wideband gauges are ideal for engine calibration purposes. Using a wideband gauge allows for more accurate.
Why install wideband gauges in cars?
Installing a wideband gauge in your car brings a range of benefits – they help you keep an eye on the oxygen sensors, improve fuel economy, and reduce emissions. Overall, these highly accurate sensors are a boon to anyone who wants to tune a vehicle.
What is an innovate wideband gauge?
Featuring patented DirectDigital technology, the handy device can display a vehicle’s air to fuel ratio with precision and speed. The gauge can also calibrate your car’s O2 sensor, for maximum accuracy.
What is the output voltage of a wideband gauge?
Many can be connected to existing ECUs, EMS, and data loggers, thanks to an extra output port. Outputs from a wideband gauge usually range from 0-4 volts.
What is the difference between AEM and X-Digital?
Its striking modern faceplate, and seven segment centre display make it easy to read on the go, while X-Digital technology allows the device to measure a wide array of outputs that other sensors can’t. For ease of use, its display is actually 87% larger than other options on the market, allowing drivers and navigators to glean an accurate reading as quickly as possible.
What is a wideband O2 sensor?
A wideband o2 sensoris much more sophisticated than a narrowband sensor, and can be relied upon to be used as a tuning tool. 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.
What is the Lambdais scale?
Lambdais scale that relates the air to fuel ratio of ANY fuel. 1.0 is stoic for every fuel. (the chemically perfect ratio of air to fuel for a complete burn). However, stoic is different for every fuel. Some fuels may need 14.7 lbs of air some may need 6 lbs of air for a complete burn.
What is the perfect ratio for good combustion of every fuel?
The perfect ratio for good combustion of every fuel is called stoic. A stoic value will always give the motor a good clean burn while taking gas mileage into account as well. Rich refers to conditions in the air fuel value were there is more fuel present than is ideal to the air content.
What causes a combustion to occur rapidly and burn very hot?
Rich conditions will cause the burn to use more fuel, but can also offer more power at the same time. Lean refers to conditions in the air fuel value were there is more air than fuel. This causes the combustion to occur rapidly and burn very hot.
Why is it important to have lots of air in a combustion process?
Having lots of air but no fuel will cause the combustion to burn very rapidly and hot , while having lots of fuel, but no air will cause the mixture to burn very cool and slowly.
Is Lambda 1.0 a good fuel ratio?
Lambda 1.0 is always the perfect ratio for the fuel in use. Some tuners argue that it is better to read air to fuel ratio’s in lambda since it will be accurate with any fuel. To be fair though, most aftermarket gauges will read lambda and convert that number to an a/f ratio for gasoline.
Why is 13.0 good?
Ok the reasoning for the 13.0 is because it is a safe afr to opperate at all RPMs with. With that being said yes you will be logging points as high up as you can rev. The thing to keep in mind is that the 13.0 is only temporary, when you get to step 10 and above (changing the tables back to stock) the computer will be commanding stoich. 13.0 is only temporary while dialing in the VE table, because it is a good safe value. Also timing does effect fueling to some extent (ie...not enough timing will result in richer exhaust gases) and therefore it would not be advisable to mess with timing as it could throw off you results.
Is 13.0 temporary?
The thing to keep in mind is that the 13.0 is only temporary, when you get to step 10 and above (changing the tables back to stock) the computer will be commanding stoich. 13.0 is only temporary while dialing in the VE table, because it is a good safe value.
Can you pass the readiness test with a MAF unplugged?
Yes you will not pass the readiness test with the MAF unplugged. I am trying to figure out a work around for it. I let you guys know when I do.
Can you change the MAF back?
As far as the timing goes...it really depends on if you are going to stay mafless or not. If you do intend on staying mafless then, no you will not change it back. When in mafless/sd mode the computer falls back on the low octane table as it primary refernce for spark. However if you do intend on adding the MAF back, then it is really just a personal preference. Some people like to leave them the same to assure optimal timing during all conditions. Other like to add in a safety factor by reducing the low octane table by a few degrees. Usually 4 seems to be the norm. If it were my car and I were putting the MAF back on I would go ahead and reduce the low octane table by a blanket of -4. However I don't think that I'll ever plug it back in until it's time for emissions testing, which upon completion I'll just take it back out.
