s2r 1k with full system

[turbowagon]

Hi
I have a 07 s2r with stock air box/ECU and the bike runs perfectly without any surging issue.
I am thinking about installing a full Remus exhaust and am wondering what issue I might have if I didn't get it tuned right away.

If I am getting the backfire or running lean issue after the installation, I am thinking about the following two options.
1.   Get the DP cams (I think it also came with DP ecu) and have ducati dealer tune the bike
2.   Have a race bike shop dyno tune with PCIII

Please let me know what you think and if you have any experience on this. Thanks!

Your more than likely go very lean. If your going to do a full system, a PCIII is the way to go. Disregard the website for down loadable maps. Best bet is a dyno run with exhaust analyzers to dial it in properly. Figure 275$ for the PCIII and another 300$ for a good shop to do the work.

If you want to really tune the S2R1K, the best starting point is to get a DP ECU. This will eliminate the closed-loop operation of the bike and give you a clean baseline for further tuning with a PC3.

When you go to a full system (even without airbox mods) you are probably going to hit up against the lean condition you describe. You can run a FatDuc to help out in the closed-loop, but there is a chance that you will have a lean open-loop which can only be addressed with a DP ECU with possibly a PC3 on top of that. This will be doubly true if you start opening up the airbox (pods or cut lid).

You will have a tough time finding a shop that can do the PC3 on the S2R1K without a DP ECU. Even if they are able to, they can't really tune the low-end due to the closed loop anyway.

MonsterMash (sponsor) will reflash stock ECUs to DP spec if you want to go that route.

Be sure to read the Closed-Loop sticky in Accessories and Mods for more info on all of this.

I'll weigh in on the side of cheapness.  I am running a full Arrow system with a FatDuc.  I had to richen up a bit (from 1:00 to 2:30) after the install, but the bike runs great.

I am not looking to squeeze the last HP out of the set up - primarily wanted the sound & look of the CF cans and any performance gain was a secondary plus.

$80 bucks and can adjust as the weather changes here in NE.

+1 on the closed loop thread.

Experiences with both this bike and adding pipes seem to vary quite a bit. I have a 2006 S2R 1000 that seemed to run fine with the standard ECU, and it still ran fine with the stock ECU even after I added Termi slip-ons and a spark mid-pipe. It didn't backfire on the overrun or anything like so many others have reported, and I probably would have been happy with it forever that way. However, when I finally got around to adding the DP ECU that came with the slip-ons and putting the open airbox lid on it really seemed to run nicer all around...it's hard to explain, I don't think there was a whole lot more power or anything, it just seemed way smoother a happier in the mid-range. So I'm sort of on the fence. I think you might be OK just adding the pipes, but for a guaranteed good experience it's hard to beat those DP/Termi kits.

Oh, and I don't think the PCIII's will work with the stock ECU (but I could be wrong about that).

Thanks for the info, I appreciate it and definitely will go read up the Closed-Loop sticky.
I still prefer the look of dual side of high mount of Remus instead of termi but I am putting off the mod until I install the long belly pan that I ordered to decide which system to go.

There is a really good thread about the ECU mods.

But basically... the PC III works with the stock or DP ecu. it adjusts the mixtures after the ECU.

the DP ecu should give you more revs and it smooths the torque curve when you make changes like getting rid of the udder which cleans up the exhaust flow.
if you get just exhausts the PC III will give you smoother curve but you'll get more power when you get the exhausts, PC III AND hi flow intake filter

Raux, hate to contradict you on this, but due to the Closed-Loop operation of the S2R1K, it is just not possible to get full tuning with the stock ECU. You can put it on, but you end up just zeroing out the map for the closed loop portion. This is different that the S2R 800 as the 800 does not have closed-loop.

+1 on this engine being different bike to bike. My bike is great with a FatDuc and midpipes (no udder), but ran like shit with cored cans. There are people who can run this setup without the FatDuc just fine, mine wasn't one of them.

GL!

it also adjust the back end of the look if i've read correctly. it intercepts the O2 sensor signal and tricks the computer into thinking it's set the way it sent it out.

They did have one like that but CARB found out about it.

the new autotune is the same feature. creates a map using the O2 sensors.
