"OFFICIAL" for you guys are just suppositions...and doesn't help at all. I'm seek and tired about "from what I understand", "I heard that", "a friend told me"....if you did something and it's working, then bring it...

this was my opinion when you started this thread.
I'm wondering why you quit learning, because for you was a learning process...

3 weeks after plugging the O2 sensor back into my Arrows full system, the bike was running so lean my exhaust pipes near the manifold were turning red from the heat. So I caved and bought a DP ECU, removed the Lambda sensor, reset the TPS via a VDST, set the trim at +2 and the bike ran so much better. The plugs were nice and evenly colored all-around. Just to see how far I could go, I set the trim at +4, and it now seems too rich. Plug not as nicely colored, and occasional popping on decel. Apart from my current effort to find the perfect trim, the bike runs and accelerates so much better

I had a similar experience and results as "twistylover". The bike runs much better with the DP ECU. Not perfect thought. Below 5k RPM could be better. I had the TPS set and the dealer guessed at some settings. Can the DP ECU be effectively tuned? and if so by whom? Dealer or 3rd party tuner.

If I have understood correctly they changed the ECU in the monster -05. So in models -05+ it became more difficult to adjust the ECU without investing a lot of money. So if you were going to buy a 800/1000 monster for a project bike, it would be best to buy model -04 or older. Correct? Do you know if there are any differencies in 2000-2004 if you think about ECU tuning (or other things to consider)?

The DP ECU is a whole lot better than stock, and I'm referring to acceleration and responsiveness at the top end.

But I still can't rid the bike of the occasional pop on decel. It isn't half as bad as the stock ECU for sure, but its still there. Maybe it's a leak somewhere but can't seem to find any.

I reset the TPS, synched the throttle bodies, and tried trim settings of -2, 0, +2, and +4. No access to dyno so I had to judge by feel and the plug color. +4 was way too rich but the bike would climb up to 230kph in no time at all. But it would pop on decel (occasionally) and plugs were dark brown. After that, and without resetting TPS or touching the throttle body synch, I tried trim settings of -2 to +2. AT 0, definitely an improvement in the decel pop, then tried -2 hoping it would disappear. Idling went to hell so I reset TPS and re-synched the TBs. Better. But had to bring trim up to 0 to improve the idling as it seemed raspy and seemed to struggle. I also tried changing the K&N air filter back to a clean OEM filter after the -2 trim experiment, and that made me decide to reset the synch of the TBs as the readings on the Carbtune dropped significantly. Somehow after playing around with the bypass valves, I got both readings back up to around 18 (from 12 thereabouts)

So while I'm happy with the DP ECU and the increased responsiveness of the engine with it, and not having the engine warning light on anymore...I'm a bit disappointed that my popping issues have not been completely erased. Am now considering getting a TPO Beast or Beast-R to see if increased air intake will fix the problem. If this doesn't work, well...will cross the bridge when I get there.

Have been following this thead and am still waiting anxiously for some kind of aftermarket fix for S2R1000 running too lean (other than $$$ for DP ECU - if this is the fix then it should at least be available to us as a stand alone chip at cost!!!). Any more news on some of the projects talked about on the first posting of this thread??

Just an update of sorts from the guys at Power Commander, an email exchange:

Me: Hi, looking for a Power Commander for a Ducati 2007 S2R1000. Bike is stock and running too lean. I would like to fix this issue! Also will want to add aftermarket exhaust and better air filter at later date. Which Power Commander do I need? If not available yet, when?? Thank you for taking the time to read this. All the best, Snap McIan

Power Commander: We have not looked at this bike yet for development and do not have an estimated date of when we will at this time. Thanks for the inquiry.

I just installed PCIII into my 695 and disconnected O2 sensor. The bike is just fine, but disconnecting the O2 sensor puts the EOBD light on, so I need to buy an O2 eliminator to correct that problem. Without disconnecting the O2 sensor Power Commander doesn't work in the lower rpm area. That is just the area I like to have more torque. I had before a Dobeck's Tfi an it works fine in a stock bike, but not with new mufflers and airfilter. Redracingparts is at the moment the only place (?) where you can buy a PCIII for 695. Unfortunally they didn't had an O2 sensor eliminator with their package.

PC III USB for closed loop S4 Rs is released. If anyone has this installed please comment.

I have on 07 S2R1K and full Sparks exhaust (no cat) and want to go with DP ECU. Can someone PM me the part number of the DP ECU THAT they used for their 07 S2R1K?

Thanks
