There is one O2 sensor per bank, true individual cylinder tuning is not possible unless the tuner created an individual bung on each exhaust pipe (impractical), even then it would need to be a wide band o2 sensor giving a wider fuel air ratio, typical 5 to 20. For expense and mandates to detect a misfire the manufacture just monitors the the bank... or 2 pipes into 1 then the narrow band o2. Then the manufacture monitors post catalyst function via the 3rd narrow band o2 sensor. One can tune/chang individual cylinder(injector pulse width) though they will not be aware of the effects because they don't have a way to test individual exhaust pipes. What tuners state they are tuning individual cylinders and pacifically how are they testing outcomes?

Hey Joe,

Yes, us tuners add a wideband sensor per cylinder. That is the proper way of tuning the bike and also from the factory all Ducatis are tuned that way. Misfire detections is also done per per cylinder and not per bank on all Ducati models and has nothing to do with our tuning or the O2 sensors. Up to current legislation (Euro5.1) there is no need for an O2 sensor downstream of the catalyst. This will be coming up in Euro5.2 in a year or two.

Don't take this the wrong way please but your most of your statements in your post above are incorrect and misleading.

Cheers,

Daniel

But thanks anyway
 
The “Ducati” motorcycle/ powersport tuners should have a wideband O2 sensor setup with a small pump on it to draw the exhaust gases into it for measurement/tuning purposes. The setups I’ve seen use the normal heat-resistant rubber/hybrid hose with a long (~2ft) soft-metal (copper) tube added so the tuner can feed the metal tube into the muffler far enough to reach the collector such that they can measure and tune the individual cylinders, even IF the exhaust doesn’t provide a tap/bung for each cylinder.

There are some adjustments needed to the exhaust gas flow timing delay due to the measurement point distance from the cylinder. The result should place the rpm closely matched to the actual AFR/Lambda reading at the exhaust valve.

Anyway, yes each cylinder is/can be tuned separately on a tuner’s dyno. You can’t get this accurate tune with any of the auto-tune devices.

Your responses indicate you're not familiar with euro 5.2 proposal. I'm bowing out of this thread and you can misled people with your pseudo intellectual writings.
Thanks for trying.

LOL BMW owners are an odd lot for sure. You know BMW is an acronym for Bitch Moan Whine. The BMW car people are the same.

From what I’ve gleaned from his forum interchanges and YouTube videos, Daniel doesn’t mislead anyone unless they just don’t understand the topic. In that case they think everyone is misleading. Enjoy your new Ducati.
 
My 2023 v4r will not red line in 6Th gear. it will not go past 15,500. Anyone else seeing this on the new V4R?
 
So, after much deliberation, I bowed down to the cooperate machine that is VAG’s and it’s T&C’s and bought the approved Akrapovic system and associated map, purely in an attempt to keep the warranty valid !

Good choice! But I believe these bikes can give much more with a good tune. That's how it feels mine at least
 
Saw this as an exhaust option.........🤣🤣🤣🤣🤣🤣
