If you have a bike built in the last 15 years or so then you probably have a fuel injected machine. Which often begs the question - do I need a fuel injection controller ? And that isn't exactly a yes or no question. Its a nuanced answer that depends on certain factors of modification and what state of tune you desire. No matter what the FI controller you choose it as only as good as its O2 sensor, we break that down for you to give you the base knowledge o get you started on your way to a decision.

Thank you Patrick, until now, I didn’t really understand the full functionality of narrow, to wide ban👍👍
Your knowledge and videos are 🔥🔥🔥🔥
During this description a key piece of information was left out.
Why do they use narrow band sensors if they're not as good at determining the error in the exhaust mixture.
The answer is that narrow band sensors are faster at producing a result.
But the viewers would prefer at least some reason why there's two distinct types.
Perfectly informative video, thank you!
Thank you that explains it.. Would putting wide band sensors void the warranty..
Narrow band, don't sniff. As they get hotter they produce a voltage, that tells the ECU that the bike is running rich or lean. ECU then switches between a lean and rich map.
NICE VID EVEN THOUGH I PUT SHOT SHOT V&H PIPES I DEBAFFLED THOSE SUCKERS AND IT FEELS FINE BUT AFTER A COUPLE OF MONTHS MY ENGINE LIGHT CAME ON. AND IT READS THE CODE FOR THE O2 SENSORS . SO MY QUESTIONS ARE IS THE WIDE BAND O2 SENSOR SHOULD FIX IT? AND WUT BRAND DO THE J&P GUYS RECOMEND FOR A 2019 SPORTSTER 48?🤔
Why don’t OEMs just use wideband sensors to begin with?
Its an expense issue.
Great info. I just installed V H short shots, V02 intake and Fuelpak ( all from J & P ) on my daughters 14 Lowrider and wondering if I needed to change o2 sensors.
Definitely would help
Most likely not unless you’ve done major modifications (past stage 2). The FP3 isn’t set up to read wide band sensors without an additional piggyback V&H module anyway.
Thanks Patrick. If you want to use your stock headers is it common practice to simply re-tap the stock 12mm bung for the 18mm wideband sensors? I ask because I've heard that a new bung should be welded and the stock one plugged, but re-tapping should be far easier and cheaper (and it looks like that what the HD 'M18 Oxygen Sensor Installation Tool' is for?)
So I'm running stock head pipes with full boar slip ons and a monster sucker intake, will the autotune feature on the FP3 be able to handle tunning the bike with the stock narrow band sensors?
So I was going to fix my 02 sensor but now I’m like wtf there is more to this
Ok, so you say the narrow band sensors can only read if it high or low of its operational zone..so when it does, is that high or too low signal interpreted by the ecm to make adjustments?
What options do I have to add 18mm wide-band O2 sensors to my 2023 Road Glide? I already have the headers with 18mm bungs.
I just wanted to know how to unplug it so I wouldn’t twist the wires up when I removed it from the pipes.
This video didn’t answer my question
I have an old evo and I'm going to be installing a 113" Ultima El Bruto matched with a CV44 carburetor and I want my tune to be perfect. This seems like a great option but how do I check the main circuit?
the Evo uses a VOES not the O2 , The 02 is on 2012 and up its in the Exhaust pipe .
@@JCcanU I'm going to tune with the "bandwidth" method and get it perfect
@@kennethwise7108 Unless your on a Dino have it tuned it will never be perfect . I changed plugs 2000 miles ago I have not pulled them to look . Looking at your plug is the best way to tune a EVO .
@JCcanU I'm liking this new method I've learned about and I'm going to try it.
Running a Slim with a stage 3 and big shots. V & H do not produce a canned map for this so am looking at the autotune function...I'm also thinking wideband would give the ability to extract more all round performance from this set up...Interested in any thoughts you may have....Thank you
I think a wide band system would definitely help your bike run at its best. I have found that the fp3 struggles at stage 2 and higher. I ended up switching to a Power Vision and couldn't be happier.
I just bought FLFBS 22, the O2 sensors are attached to the end of the mufflers.
I want to change the mufflers to get a better sound, is it OK to change it at home or do I need to do it at the dealership? Also, do I need to change the full exhaust system or I can change only the mufflers? What if I took the sensors out are the gonna effect the engine performance?
If I install wide band sensors on my fully stock 2019 Heritage 114 will my stock system correct itself for the differences between lean and rich running?
Sadly, no. Wideband sensors operate between 0 and 5 volts, where as nearrow band sensors can only go up to 1 volt. this means that even if you manage to hook up a wideband, it could just fry your input on the ecu. On top of that, the computer wouldn't know what to do with these voltages. between its full range of 0 and 1 volts, a wideband sensor reads in the ballpark of 14 to 15 AFR, while 0-1 volts on a wideband's 5 volt range is usually around 10.5 to 12 AFR.
I had my CB650R tuned and the tuner disabled the stock narrowband O2 sensor. Is this normal procedure? If I ride up to altitude, will my bike run super rich because of it?
Great info !
I got stage 2 in my 03 Harley. That being said there are no 02 sensors in my exhaust is it possible to add them and is it necessary?
I have the Dyno Jet power vision. Can I just get wide band O2 sensors ? 2019 Road Glide Ultra
I'm guessing it's basically the same with a car? Yeah. I'm going to say yes.
Where can i get wode band o2 sensors for 2018 iron. I have a 1250 big bore and dynojet power vision.
What is open loop and closeloop?
And how it functions?

I have a 08 buell XB12 and when I purchased the bike it appeared to be running lean. Even the old Harley mechanic I had change the oil (wanted him to be familiar with the bike in case I ever needed something above my head) felt like it was running lean. Cracking a bit, kinda starving. I switched to a barometric sensor and open loop and it ran A LOT better. However, I have fouled two brand new plugs in less than 100 miles. It didn’t do that before. Did I make a mistake? Should I purchase a wide band sensor abs go back to closes loop? Still learning and exploring options but any advice.
What modifications are done to the bike?
@@jpcycles when i got the bike, just the stock exhaust/intake mechanism was removed and a “race” ECM installed. From what I’ve learned, moving to any aftermarket muffler requires this because only the Buell stock muffler and Buell race muffler has this mechanism installed. I added the barometric sensor and tune from a site called revision Moto because I felt like it was running very lean. There seemed to be several people against the barometric move and several people who loved it. I tried it and I think it’s better, maybe, than what it was. I simply want the bike in the best tuning shape possible. I don’t need any more horsepower than that monster 1200 will give me.
So if you have a harley with O2 sensors and pipes without O2 sensor ports do you HAVE to add ports to the pipes or is it possible to run those pipes? Have a FP3 as well.
You can run them without the O2 sensors, you will get an engine code. The reality is that stock narrow band o2 sensors don't do a whole lot. th-cam.com/video/Z64DH1cxGFA/w-d-xo.html
@@jpcycles awesome, thank you SO much for the information, it is GREATLY appreciated!
Hi. What's a closed loop system ?
th-cam.com/video/5wro4Wj2gk8/w-d-xo.html
I have slip on Vance and Hines pipes. Bike isn't running the best. Can I change from narrow to wide without a tune?
You need a tuner that can read the wide. Harley only reads the narrow.
These videos are awesome! HOWEVER, a couple of hours earlier I went into the website to gather some more info and Mr Mark was a total asshole! I just wanted some confirmations and a lil info about what my codes were and how to go about it and he said "I cannot fix your bike via live chat. You suppose to track the problem down. Any other questions?" Then he ended the chat instantly before I could even say anything.
What were you trying to ask? Not fixing your bike over live chat is a fair response.
So I installed a stage 2 in my 2021 lowrider s and harley says that they can dyno it with the wide band sensors, which they will install and then when done they reinstall the narrow bands....? That doesn't sound right. They say that they make the adjustments in the ecm that's why it can run on the narrow band sensors. I have a pretty aggressive cam so, I'm confused
