Thank you again Rising Boost for quality content (AFR). Keep safe brother!!

[@RisingBoostYT]

Thanks, will do!

[@florinadrian7957]

there is only boch sensor the rest are bulsiht and even on bosh you need to find the specific tolerance of each part , after you find the tolerance of each individual part then you can make tuning , all the rest is like running bind !

[@RisingBoostYT]

true, $19 is not buying quality... or a bosch sensor. I did buy the innovate wideband and Bosch 4.9 sensor but it was over 10x the price. video on the channel.

[@litare4328]

Why do you even care about tuning, it's narrowband anyway...

[@keeganxw]

Because I’m trusting my setup on a $19 narrowband that has a decimal point at the end.

[@RisingBoostYT]

Hi Keegan, I tested it so you don't have to, but you are correct, if you refer to your "setup" I assume there is some money spent on it and it's not stock. if the setup is worth more than $200 stay far away from the narrowband.

I bought myself a project car a few weeks ago, a vw corrado with the 1.8 16V KR engine, since I have no way to check if the K jetronic injection is working right, I might get one of these sensors so I can actually check if its working as it should lol 😅

[@RisingBoostYT]

Hi bro, very cool car, you may want to get a wideband setup, they about $250 but gives you a more accurate and wider band reading of the air fuel ratio. The cheap gauge does work if you on a budget though

[@mobilebeeler]

I would like to see synched footage. Because narrowband usually only reads from 12.0-15.0 and i see that one is ranging all the way into the 10s and even 18s... I guess they could have some sort of voltage diode in the chip inside the afr narrowband gauge... Idk. Im always aem.. Dont even trust innovate. Just aem. But like i said id like to see a side by side comparison. Have u record one and a mate record the other. Hitting record at the same times. Id be interested in buying one for my non tuned daily driver as opposed to my $200 aem wideband for it. Thanks!

[@RisingBoostYT]

Hi Matt, yes to my understanding the narrowband should not work, not sure if they do "trick" the outputs, but it is possible. the gauge does read from 10.0 to 20.0 AFR "or so it says". the thing that shocked me was the the cruising AFR was about 10.7 to 10.4 on the Innovate wideband and it was the same on the narrowband. sadly I had to remove the narrowband to fit the wideband so I dont have both in the car at the same time. so syncing up is not easy. but I will try and then post a short.

[@tasos209]

Great videoe mate. How accurate is it if the working ratio is around 12.0-12.5?? Planing to use it on a bike

[@RisingBoostYT]

This sensor is less accurate the further away it gets from 14.7, at 12 it is still kinda accurate but I won't trust it for tuning, only to monitor afrs

[@tasos209]

Got it. Might be 0.2 off around there or more? What do you believe by experience?

[@RisingBoostYT]

What I noticed is once the afr goes to around 10 it will move around randomly from 8 to 10 almost like the sensor can't read that low so the numbers become random till it goes back to the readable range. Same with if it goes to rich.

[@SlickTwigDotWAVfile]

@@RisingBoostYTmakes sense, if it’s narrowband, in german it’s literally called “jump sensor” cause outside the very narrow accurate area it just jumps to rich or lean.

[@anhbillying]

Hi guy, i really want to know if it works correctly when comparing the number values ​​it gives to wideband, i don't care if it responds slower than wideband because it only 20$ and to buy a wideband sensor kit in my country is not easy...

[@RisingBoostYT]

Hi Anh, The readings are accurate when cruising in a steady state, both sensors gave me the same values when I drive 80km/ph. the narrowband is little slow and less sensitive. but the big thing I did notice is the narrow band struggle to read a very rich or very lean ratio. if I make my car run lean the narrowband shows lean but stops being accurate after 17+ air fuel ratio as it keeps giving the same readout even if I make it more lean in the tune. so not great for tuning but better than nothing and also very good to just monitor the AFR. it is accurate if your AFR is near the target 14.7 AFR. I do recommend it for the price.

[@anhbillying]

@@RisingBoostYT yes!! my aim is to keep my motorcycle running nearby to 14.7, as you say, so i can trust it to work quite correctly if installed correctly, combined with spark plug color review to give the most realistic assessment. The "Dynoracing" brand is from china & i can easy to buy it for cheap price (about 17.5$), i have used through oil temperature gauge, tachometer also from this brand & i found it to work accurately and durable for that price. The information you provided is very helpful for me, thank you very much!

[@openmilsim9183]

@@RisingBoostYT Hmm i have never had any use to Widebands showing very lean anyway. I tune until i se it closing in on lambda 1.0.. As long as you can se if its a lean or rich you can always calibrate the fuel.

[@jasonkeefer1716]

A narrowband gauge is just a gimmick. It will oscillate back and forth expressing the waveform of a normally functioning sensor (between .1 and .9 volts, with .45 being stoichiometric). It does this because the catalyst can’t efficiently clear at stoichiometry, Nox being cleared the best under rich and lean conditions, CO at lean, hydrocarbons at stoich which is also the best fuel economy but the worst for Nox. Its is absolutely useless for tuning and pretty much useless for obtaining an accurate AFR. Wideband air/fuel sensors however, can give you precise readings and is really the only way to go.

[@RisingBoostYT]

Thanks for sharing our knowledge

[@webleck1138]

Hey brother nice video.. got a question.. i have the same gauge and i want to use it on a motorcycle.. does it work or not? Also I didn’t understand where you connected the green cable

[@RisingBoostYT]

Hi bro, the Guage does work, however it works best around 14.7 AFR, if it goes too lean or very rich the gauge not be accurate. Green wire goes to the signal from the sensor. Make sure all negative wires goes directly to battery negative

[@michaelstarr5861]

What does work to tune in my carbureted small block Chevy or get it close?

[@RisingBoostYT]

Hi, for a carb setup yes, i think it will be helpful, its good if you get the AFR close, its just not accurate if its far off from 14.7

[@dexter7s847]

i got oil gauge，water temp and voltage gauge they have 3 wires all is battery 12 v 。can i put them to one fuse tape？for the power

[@RisingBoostYT]

Hi, yes you can. Make sure the source wire is not too thin, earth the gauges well, a good test will be to connect your voltage gauge at the battery directly, then at the "in car" location, make sure there is not a big voltage drop between the reading at the battery and the reading inside the car.

You can use your Lamda also in the same wire . Why you instal another one Lamda

[@RisingBoostYT]

Hi, if the stock sensor is the same 0-1v sensor it should work with the gauge, not sure if you can have the wire go to the ecu and gauge at the same time as the smallest voltage drop will affect the readout. my car is a JDM/RSA spec so it did not come with a 02 sensor from factory.

hello sir can you tell me the aem work better or other cheap afr gauge can working ok also because think buy and dont know what the best buy for safe and correct show thank you

AEM is much better, the cheap gauge use a narrow band sensor so its only accurate near 14.7. The AEM is always accurate and trust worthy, don't rist your setup with a cheap gauge, its only good for getting a indication of afrs

[@josephhall6489]

I bought that cheap guage and when i start car i get a reading of 14.1 then once i start driveing it flashes 10.0 all the time❓❓

[@RisingBoostYT]

Hi Joseph, flashing at 10 normally means an error, sensor is too cold to read (must have heater wires connected) or AFR is out of readable range (to rich or lean) or the sensor is not connected (wiring) also the sensor should not share wires with anything else, any resistance in the wiring will cause incorrect readout or the error. connect via relay directly to battery both positive and negative.

[@tasos209]

​@@RisingBoostYT thank you. Make sense now. Definitely used a relay. Now seems to calculate AF correctly

[@ekremarslan3270]

Good day brother, I bought an AFR watch like yours, but we couldn't get it to work properly. There is no brain in my vehicle, so it is not injection-powered. Can you help me?

[@RisingBoostYT]

Hi, it should still work fine, mine is not connected to any ECU, the signal wire from the sensor go directly to the sensor wire on the gauge. also very important is good wiring to the sensor and gauge. use a relay to trigger power to both sensor and gauge, don't just tap into a random wire for 12v or ground. Grounds must be perfect as any voltage drop will affect gauge reading. do not ground to the fuse box pins or share a ground wire with anything else.

[@ekremarslan3270]

@@RisingBoostYT Thank you for your information, we used to try it somehow, but this time, it shows AFR at low speed, it does not show when I press the gas, if I go slow, it shows fine, depending on the gas response, but if I go fast, it remains constant at 20, why does it do this?

[@RisingBoostYT]

@ekremarslan3270 it could be maxed out lean, the narrow band sensors dont read accurate if it is far away from 14.7 so its to far away from that. Perhaps your setup running lean? Did you connect the sensor heater wires?

[@ekremarslan3270]

@@RisingBoostYT I installed it right at the bottom of the manifold, but I know it should be 1 meter after the manifold, maybe that's why it's not reading? All cables are connected but it still stays at 20 at high speed.

Hi Zeus, I do not know for sure, however I do not think so. this gauge uses the narrowband 0v to 1v to give the output, a wideband uses 1v to 5v. I would say No it will not work.

Hi Devonta, on the sensor, the 2 white wires go to 1 positive and 1 negative. The grey is an earth, so yes, it can go to the negative on the battery. Black go to the sensor signal on the guage. You must however put a relay on the white positive wire or the sensor heater will stay on forever and drain the battery.
