MTS1200 Advice: fatducs or O2 optimizers

[loc4me]

Getting a new exhaust soon. Will be going with the LeoVince midpipe. Given the feedback reports from those who have already done this the fueling will be a bit lean. I have been reading the thread on the new O2 optimizers from dynojet but I am still a little unsure of the benefits of picking them over the fatducs. They appear to both increase the AFR in the closed loop section of the ECU which will be needed once a free flow exhaust is added.

I'd like to get some feedback on which one would be a better choice and/or the advantages of each solution. If I ever decide to add a powercomander I could see the O2 optimizers having more value as they would work directly with the PC, however this is not on my purchase list at this time.

O2 optimizers appear to be adjustable as well.

To the Fatducs credit there are a lot of people on this forum using them with out much complaint and that statistic gets a lot more weight in my book.

Thoughts?

i haven't used the optimizers, but the fatducs are working very well with my Arrow full system. the only gripe i have is sometimes i get a very slight hesitation when slowly opening the throttle at 3200-3400 rpm. it really only happens occasionally when the bike is cold, and almost never after the bike is warmed up.

the most elegant solution i'm waiting for is a reprogrammed ecu.........no lambda sensors, no PCV box, no extra wires running all over, no fatducs, no duc.ee exhaust valve servo eliminator. until then, i'm OK with the way the bike is now.

think i'll be calling this Mr. Lofgren guy soon

I'm taking basically the same route as thelumox. I think he got the first set of fatducs when they came out, I probably got the second. I got them based on excellent results with a fatduc on my 1100 multi. I plugged them up, and my stock 1200 has been running fine since, although I may ultimately consider the ecu reflash as well. To my mind the reflash is the best solution, but I'm in no real hurry.

If in the future you're thinking about going with a PCV as a piggyback and getting a full tune, staying with a PC product would be more ideal. However, if you're going to say this is it, I want the best rideability with what I have then just get the fatducs and be done with it.

I have the full Termi and it's associated ECU.
The fatducs cured almost all of my low end fueling problems.

I Im not sure what fatducs are never heard of them here in Au,if it exhaust you are talking about we have Q.D which is half the price, bang in a rexer map best out come i and others have had theres many running around over here with this set uo, no strapping a extra brain im told dosnt work in real time, a qoute from Arther guru ,knocks out the somthing senser and disables the flapper valve all this against the full termii system a bloody good deal if you ask me and the Q.D pipes bring music to my ears

Interesting side note. I had my bike at the dealer for some warranty fixes and 600mi service. I've had lots of problems with the fueling below 3500rpm. Asked my dealer if there were any updates when I picked it up. He said there were not. I have no idea what he DID do but the fueling issues and stumbling is almost completely gone. Super happy. Only have a couple miles on it though. I'll report more later.

Fatducs are O2 Manipulators. They "are an economical solution to alter the closed loop air-fuel ratio on many Ducati Motorcyles. O2 Manipulators are “plug and play” requiring NO cutting or splicing of wires and installs inline at the factory oxygen sensor connection. O2 Manipulators work by altering the oxygen sensor output voltage. This slight reduction in voltage forces the ECU to add additional fuel."

I have installed the Optimizers without the power commander. The drivablity was dramaticaly improved. It is dead simple to install and worked very well. I have since added the PCV and so far the optimizer is working well with that too. Just my opinion, but I'm sure you get the same results with either Optimizers or Fat Ducs....Their really both doing the same thing. The ideal fix is custom tuning of the ECU, if that option is available to you.

100% Agree. I chatted with Doug Lofgren about re-flashing the ECU and I'm really tempted to drive the 1800 from AZ to MN and get the bike tuned by him. He knows his stuff and is a pleasure to talk with.

I think I may hold off on any exhaust updates until I can get the bike properly tuned. My dealer was able to get rid of almost all of the surging/stumbling/hesitation below 3500rpm. I have yet to ask him exactly what he did but whatever it was, he did a good job. Doug said if the mechanics paid attention in training that Ducati shows them how to read the adaptive fuel values from the ECU for each cylinder and how to equalize the AFR (for each cylinder) by syncing the throttle bodies and such. I guess my dealer paid attention in class.

I'm really happy with how it's running now, just wish I could get rid of the cat, which looks like a boat anchor. You know it's bad when your wife asks you what that ugly thing is hanging down underneath my bike. :roll eyes:
