Narrowband vs Wideband AFR Gauge

You need to buy an AFR gauge but there are so many options. Can you get away with a cheaper narrowband AFR or spend all the money on a wideband AFR? Which is better? Which will give better results? Are they different? I'll explain the difference so you don't waste your money!

All the reasons you mentioned for getting a narrowband are exactly why I got one. My car is mostly stock, it's 20+ years old now and I just want it running at Stoich. It is prone to developing issues like vacuum leaks so I use the data to help me troubleshoot issues, plus it looks cool! Definitely better than having to look at the live data with a cheap OBDII. I just want a normal driving car, not a racecar. Great explanation!

, same with me. I

Overall good video but confusing at a few spots. @ 2:15 did you mean narrow band? @ 3:45 did you mean wide band? @7:30 12:1 narrow band out of range. Did you mean less than 10:1? It looked as though 12:1 was within the range on the narrow band graph.

[@stuckinmygarage6220]

Exactly: The time you spend, the frustration of not getting tuned right, the wasted fuel, more. Wideband. You learn more while you drive and test your pedal action, the car response, the changes in altitude/weather. To me, it's like a toy that enhances your driving/tuning experience. Not better than beer, of course. :-)

[@MuscleCarSolutions]

It’s a tool that for sure has made everyone better at tuning on the carburetor side and has given such amazing leaps forward for EFI. Beers to you!

[@nova467spanker]

@@MuscleCarSolutions Not sure if you noticed at the 2:13 mark but you mixed up the voltage measurement for the 2 sensors. You said the Wideband has a measurement of 0-1v but you should have said the Narrowband has that. Good info though.

[@671mach]

I bought one of those led edelbrock afr meters back in the early 90s which are narrow band. If I remember correctly, it was over $200 back then. Definitely wasn’t $50. I always found it to be kind of helpful but only if you were in the ballpark to start with. Maybe they were costly because there was not much to choose from back then?

[@Darkjedi99]

For the narrow band, Couldn’t you just monitor the voltage on the 02 sensor if 0.5 is stoich maybe even add a resistor to tune the voltage if needed?

[@Backfire10]

Just a correction. at 2:17. Wide band reads from 1-5 volts. Not 0-1, Just FYI. You may have ment to say Narrow band.

[@mattack6779]

I was really hoping this guy would mention carbureted applications and if there is any reason to buy wideband if only trying to make sure your not lean all of the time.

[@MuscleCarSolutions]

The whole point of an AFR is to monitor operation and evaluate changes made. This is simply a discussion on the differences in the two types of sensors. As a tuning tool, I assumed it was understood it’s extremely valuable and I recommend using one of you can afford one. Simplifies and speeds up the process and gets better results.

[@project_ej2]

Great video sir! I recently purchased a narrow band gauge by mistake, and I'll be honest I've heard of wideband gauges a million times but never a narrow band. And I knew the face of the gauge was a little different, but didn't think anything of it. It wasn't until I tried to hook it up, did I notice something wasn't right.

[@MuscleCarSolutions]

Well at least it was probably really cheap!

[@neruelk]

Wow thanks a lot for this video! I'm looking for a sensor with a gauge to put in my '65 Volvo, just to monitor if the carburettors need adjustment. Now its clear I can just take the narrowband!

[@MuscleCarSolutions]

Narrowband will give you less info.

[@neruelk]

@@MuscleCarSolutions Exactly! I only need to know if it runs stoich or not, i'm not interested in the exact value!

[@Justdigit2]

Yes I am that narrow band guy.... Classic standard T-bird. Thanks

[@MuscleCarSolutions]

Narrowband O2s do work, they just don’t provide much information that’s helpful with tuning. What are you using yours for?

[@Justdigit2]

@@MuscleCarSolutions Just to be assure my carburator is tuned right. And for the extra milage... 1964 Thunderbird 390FE with 1406 Edelbrock carb

[@MuscleCarSolutions]

Mileage driving is really what the narrowband is best at. If you can keep it in that prime target area, you’re doing about as best you can!

[@autumnjeserich2689]

I hope its not too late to ask this question, but I'm working on a truck that has factory efi with narrowbands. the engine had a big failure so it was rebuilt with performance in mind, its still NA but it has a longer stroke, much higher compression, better intake, bigger cam, ect. On my factory ecu I have an operating system that would allow me to wire in a wideband to replace the narrwoband which I plan to do eventually. But as I'm getting ready to fire up this engine for the first time can I get away with a narrowband until I have the funds for widebands with a conservative tune? I can't run a factory tune because the engine is radically different like not even the same displacement. Not gonna lie rebuilding an engine which needed all new internals and springing for a forged bottom end has bled me dry otherwise I'd just go get a pair of sensors

[@fon868]

Thank you sir this video very helpful

[@juancamaney3562]

Great awesome video👍. I have a question. Can a wideband sensor work on a regular ECM from the factory or do I need a stand alone computer ? 🤔

[@ironhead320]

If you don't know if it's a wideband or narrow can you test it at the signal wire to find out if it's wide or narrow sensors

[@chriscoralAloha]

That Panchos white queso must be good stuff.

[@BPattB]

Hope you enjoyed SEMA! I think I could really use a wide band AFR on the Mustang. Cold starts are stinky and more smokey then my neighbors like lol. The car runs strong once warmed up with the new avs2. Maybe now that I'm a little older I'm more cautious, but the idea of running lean and not knowing eats at the back of my mind..So I'm purchasing an AME X series from Summit because without one I will literally drive myself insane. Just a heads up I'm sure I'll have about 3 or 40 questions. Any help you can offer as always is really appreciated. Between you and the gys at C&C Auto Works I've got so much help. I appreciate you guys a bunch.

[@MuscleCarSolutions]

Thanks! AFR is an amazing tuning tool. I wish more would take advantage of it rather than thinking that “seat of the pants” tuning is effective. You leave a lot of power/economy/drivability on the table with that old antiquated method. It will make your tuning time much quicker, but there’s still lots of driving between changes to verify it’s what works across all situations. You’ll enjoy it. Get busy!

[@junitomaster6689]

can i "tune" a turbo ke jetronic with the narrowband? i just wanna keep it in stoich range?? it is tuned by an allen screw

[@wtf0101]

Narrow band(o2 sensor) measures oxygen, wide band (af sensor)measures gasses

Thanks for the upload

[@auggiedog5]

Good job Now I understand !!

[@warrenpeas]

so, when tuning a motorcycle with a carb and no efi is the narrowband adequate?

[@davidrowland2354]

Can I add one if my truck doesn't have a ecu computer

[@william5787]

Hi Sir, 2019 5.0 Mustang. Would you recommend a Duel set up & where is the best place to install the 02 Sensors? Supercharged & Headers installed on the vehicle. Or do you keep the original factory 02 Sensors & also add the Bosch 02 Sensors as well. My explanation is because I'm from Australia 🇦🇺 if my terminology is different. Kind Regards, William.

[@MuscleCarSolutions]

The factory computer will only monitor however many channels it has in the system. If there’s only one, it will monitor one and you can’t add a second. If you want to monitor it on your own or are switching to a aftermarket stand alone system, then two is always a better choice to monitor both banks.

[@mikesmr2341]

I know this is an old video. But I’m going to ask I have an 85 Mr2 with the 4age NA. All run off the stock computer. Since all I am trying to do is know lean or rich from the gauge is it wise to just use the narrow band? It is an Autocross car but no power adder or stand alone fuel management. Just for fun. Thanks for any advise.

[@beefcakemonsta]

Wideband is a better choice, it gives more data between the signal voltage. Widebands are best to none when it comes to monitoring your afr (that's why all tuners use this). But if your really in a budget and just want to have a reference point to where your afr is, a narrow band with a wider breakdown on its signal voltage would be better. I think dynoracing has one wherein they broke down the signal voltage of 0 - 1 into decimal incriments to get a sort of precise reading on your afr during the rpm range.

[@jorgecapello2628]

is it possible that after replaced a narrowband by a wideband sensor, I keep getting a P0032 code (2009 corolla)? thanks

[@christiancole7156]

Thank you

[@jeromezepeda8878]

Narrowban sensors now can provide numbers that you can see

[@MuscleCarSolutions]

Narrowband sensors read rich or lean but will not tell you how far off the engine is from stoich. A wideband sensor will give you those numbers.

Great video Thank you

[@MuscleCarSolutions]

Thank you

[@332ARA]

So would you say that a narrow band gives you the same information as reading plugs?

[@MuscleCarSolutions]

No. Properly read plugs can give much more detail than the limited feedback from a narrowband O2.

[@jaysondelossantos5078]

Can we use same gauge and just switch the narrow band sensor to wide band sensor?

[@MuscleCarSolutions]

No. The gauge isn’t calibrated to that range.

[@jaysondelossantos5078]

@@MuscleCarSolutions I see, that's make sense.

[@scottbartlett4853]

In (my) narrowband application there are four sensors, two pre-cat and two post-cat. Is this the same with wideband applications? I am doing an engine swap with an aftermarket ECU. Do I need four WB sensors? Or do I block off my post-cat bungs?

Really depends on what your device is asking for. I don’t have a clue what system you’re using or is it something factory?

So im still new at getting a wideband, just received my narrow band afr today and I was just getting it cause my other pod was empty. I do have a street manifold that looks like the skunk2 ultra series but not really on planning on doing anything major on it just basically i/h/e and might get a chip ecu in the future. Should I still get a wideband or just stick with the narrow since I'm not planning on doing anything big yet basically how the economy is going on now with the gas prices 😄.

[@MuscleCarSolutions]

It’s just limited info you’ll receive but if you’re hypermiling and just watching economy it’s probably going to give you everything you’ll need.
