It can happen and has been reported many times on the forum. If it's too bad then get it serviced or control the throttle more, less blipping. Mine did it sometimes but only when down shifting from second to first. The termis will fix that problem too. I haven't had it cut out on me since installing the full termis. I know the cost but if you can find a good deal, jump on it! Totally different bike.

 

...The termis will fix that problem too.

That is a little misleading. It isn't the termi that helps the issue, it's the DP ecu that comes with it that does the trick. Same results can be achieved with PCV, Bazzaz, Rexxer, etc at a fraction of the price.

I can confirm that a drycell battery will also help the issue. You get stronger spark at the low RPM's and it helps balance the lean-ness.

Root cause is definitely that the bike is lean and the only proper solution is fixing the fuel map.

 

JHP, thanks for the reply. I suspected as much. More money to Mr and Mrs Ducati.

Cheers...

 

With the Termi ECU you can tune the whole rev range. However, with the stock ECU the PCV can't get tune the bottom end (below 5000 r.p.m. I think) - you have to install the Dynojet O2 optimizers as well. All up, with labour, cost me around £900 (UK). That's 40% of the cost of the Termis right there.

 

Bazzaz allows full range tuning. It's actually one of the reasons for my decision to go this route.

 

Gentlemen, all replies appreciated! Will be getting the pipes and ecu, as I want more noise as well. So will go the system. It's funny (not haha) how a bike that has been designed for low down torque and power could be so restricted in the low RPM. This bike is dying for more fuel and a free flowing exhaust.

 

unfortunately, it's not ducati's fault, it's the emissions requirements that are causing the issues. below 5k the system is governed by the O2 sensors that intentionally lean the bike for low emissions. The full termi system and ECU disables these (i think) making it run as it was intended.
my bayliss replica has a 70mm full system and the std system is in a box, O2 sensors still attached to the std pipe work and has no issues at all. I'll be disabling my sensors as soon as i can which should make the ECU run on a default setting that runs richer.

well i asked around and the closed loop portion of the map is activated below 4500rpm and below 15% throttle openings which is most low speed and cruising speed riding, the ecu closed loop runs it at 14.7:1 AF and i've been told the d/p ecu for the full system is the same as the 02 sensors have to be reinstalled although i'm not sure about that as i only have a slip on.

paul

 

this is the first i have heard that the DP is closed loop. i guess it can remain closed loop as long as you can get in and edit the target AFR from 14.7.

______

also here are some common stoichiometric mixtures
* Unleaded 93 octane: 14.64
* E5 93 octane: 14.35
* E10 93 octane: 14.08
* E15 93 octane: 13.79

as you can see, the bikes are set for an un-blended fuel. those of us that are forced to use e15 are running λ=1.05 (λ = AFR/AFRstoich) which is lean.

it also explains the excessive decel popping and the cherry red headers when it idles. these machines just weren't designed with ethanol in mind and we are forced to pay out the nose to get them to run properly.

and, you can get PCV to edit the closed loop. you have to purchase their o2 optimizer for that functionality.

 

Mine did this when it was new and did it every once in awhile changing from 2nd to 1st, I have CW exhaust fitted from new and it hasn't done it for the last 1000ks and I've done 3000ks now. Probably do it tomorrow now.

 

found these guys who sell the fatduc type manipulators, they do them for our diavel too. says they don't suit the d/p ecu that bypass the o2 sensors but i'm not sure if any do on the diavel

Leanness solved. Actually might be a little fat. Not a perfect solution but cost effective and I'm happy that it no longer lean surges at steady throttle.

Eventually I'll be going to one of these with the self mapper:

I have nothing to complain about. I have only a slip-on and it has always run great. I also get very good mileage. Sorry to hear that so many think their bike needs to be improved. I guess I'm one of the few on the forum that bought an out of the box great performing machine.

 

have you ever compared a stock ducati to a properly tuned one? to the average rider, my bike may seem to run just fine. I can just remember back to my s1k prior to and after getting it tuned. I didn't know any better before they tuned it...but afterwards! afterwards, it was a completely different machine. soooooo much smoother down low, noticeable power increase, almost complete loss of the decel pop. I can't wait to get mine tuned up properly and awaken the beast.

 

Same here. Bone stock and runs fine. (Exhaust pops are normal)

 

exhaust pops can be a symptom of lean running........

that said, the factory has designed these things so you can't touch them, you can't even trim them according to the dealer, just reset WTF?? i guess they have their reasons but i'd much prefer to be able to fine tune the running, mines pretty good, no pops on the over run or surging but it's definitely still lean.

My AMG slip on kit still uses the valve and the closed loop function so i'd hazard a guess and say the termi slip on does too.
now, who's got a full system? does it have the o2 sensors plumbed in and plugged in??

 

Well I think it's pretty clear, time to rid my bike of the standard exhaust and ECU and fit the full termi system. I haven't confirmed yet whether the d/p ECU is closed loop below 4500 rpm, or whether it still uses the O2 sensors. However I would be VERY surprised if that was the case, because why bother calling it a performance system. The manipulators and Bazzaz options are fine, but I want this thing to run the way it was designed to run. Don't want more power or anything like that, just not going to put up with it running lean anymore.

 

use of o2 sensors = closed loop. i think you are after changing the target AFR in the loop. i'd be interested in knowing that also.

 

The full Termi does not have the exhaust valve.

 

what about the o2 sensors?

 

gone.

 

I also confirmed that the full termi does not have O2 sensors!

 

Wrong assumption, the full Termignoni kit comes with thread to put back O2 sensor.
In fact only for the front header as the first part of the rear one stays in place (not part of the kit, same part as stock configuration).
So……………….. the rear O2 sensor is fitted onto the rear header

I did the installation myself on my bike and for sure, both sensors are plugged but I can't tell if they are ignored by the ECU.
Could try to unplug one of them to see if a fault is reported when turning engine on, but only no default would mean they are useless.

 

I thought the o2 sensors were still used but not positive.

 

not on the full system.

 

My instructions show the sensors are retained.
Have not installed yet, waiting to have them ceramic coated first.

 

Thanks for that guys, it's always nice when people who don't actually have first hand knowledge pollute a thread with assumptions, why post if you don't really know????

so eagle4, you installed the system and it said to plug the O2 sensors back in? i would say they are used if that's the case, i have a 1098R with the 70mm full system and there is no facility to run the sensors, you even get block offs in the kit for the bare plugs!
If you can't tell it falls into and out of the closed loop mode while you ride it that's a good sign that A, the tune is very good and suits your engine, and B, whether the closed loop function is used or not it doesn't really matter cause it runs well!

paul.

 

Sorry Paul, mine doesn't have 'em, guess I'm special.

 

well that's odd, eagle 4 's pic clearly shows the o2 port in the front header, and just for giggles i went to my dealer today and on the wall is a full system assembled and it has the o2 ports as well. the mechanic says when he fits them he refits them and plugs them in but couldn't say whether the d/p ecu bypassed them or not.
wonder if there was a change from the 11 cat to the 12 catalogue?
i'm more confused than i was before now, and although mine runs ok with the slip on and ecu i'd like to be able to turn the closed loop part off!

 

although mine runs ok with the slip on and ecu i'd like to be able to turn the closed loop part off!

thats where the tuneboy comes in, the euro spec full systems must be different to the u.s. models. So you can use the lc wideband and 02 sensors with the euro full system

 

Quick question for anyone. Ive got the same problem, I cant even idle in first while riding in traffic without the beast lurching awkwardly and the pop is very noticeable after releasing the throttle. Could I use the O2 Manipulator from Shift-Tech with stock pipes?

 

It's sort of a hack solution in my opinion, but it will "work"
