OFFICIAL: Closed Loop ECU mods

Its cool that its as adjustable as an RB3 module, and entirely replaces the ECU. But it doenst make it any more cost effective than a DP unit. Though for race applications its great.

Id tell him to put his money where his mouth is and produce an adjustable S2R1k ECU without an O2 sensor.

He allways delivers ,and is by far the best dealer in the world (42 year ducati dealer)
If you let him tune your bike you get a dyno before and after

My dealer (Den Biggelaar in the Netherlands) says on his site that he can rewrite any Ducati ECU from 2003 and up

Could you check on the application? Is he running a FIM chip?

It is actually more expensive than a DP ECU (~$1200 vs. ~$1400), but according to several folks the DP ECU is only a good start and you should really get a PC III on top of it which is another $350.  The Nemesis does allow you to get rid of the immobilizer and use any after market dash...

People have said so much about "yea we can do E3 bikes with the o2 sensor" etc.

its always a big fat lie to bring in people. DPECUs cannot be adjusted, you can flash them since it really is just a chip. but youd have to know what the DP ECU speaks. which is about the same levels as cracking a code.

This guy doesn't lie
Mailed him what he could do with the after 2003 ECU's
Answer : everything
He can reprogram it ,adjust it , remove the immobilizer ,adjust fuel , adjust ignition, remove rev limm
I want to say that this shop give warrenty on every thing the do

Could you provide a tel or email...I'd like to see what he help me with on a S4RS that runs too lean.

Sounds like you know this guy pretty well. Im with CDawg, please provide contact information so we can get pricing. Someone here can donate a stock ecu to have it reflashed and tried on someone else's bike.

Thanks!  No worries as my wife speaks dutch.

Cdawg let us know how that goes. I bought a power commander 3 today and will attempt to use it on my 06 S2R1K........... When I get my make the beast with two backsing bike back

This guy has found a pot of gold. I might just nip over the channel and talk to him.

I own a 2006 S2R 1K with around 10.000 KM on the clock. I had Marving headers, a 2-in-1 Shark CF can and K&N air filter with open lid installed. It was all dialed in using a PCIII. The work was done by an approved Dyno Jet center.
When they tried to disconnect the O2 sensor the engine lock warning light would come on. In order to not get fault readings, they typed in a fixed value for the O2 sensor No big deal, the sensor is just fixed on the inside of the frame on the left side, where you don't see it.
All in all it gave a gain of roughly 6 HP and 12 Nm on the rear wheel over stock (they made a run on the dyno before they started working on the bike). The bike pulled harder and ran better, especially in the low and middle rpm range.
A few things annoyed me though. When cold the bike would idle very roughly and go up and down in rpms, until the engine was warmed up, showing 50 degrees on the temp. gauge on the clocks. Also it didn't run the same way at all times. Sometimes the running would be smooth and sometimes the engine would vibrate a lot especially between 3500 and 5000 rpms. It would even change on the same ride. It would change from smooth running to harsh running after stopping, for instance at a red light – without stopping the engine that is.
In other words, I could go from loving the bike to thinking "now, what the h*** is wrong" in a matter of minutes.
I had a look at DynoJet's homepage and learned that they do not make PCIII software for the bikes that are equipped with the stepper motor for idle adjustment. Apparently the problem is, that the stock ECU and the PCIII are fighting each other, trying to control the stepper motor. At least that seems to be the general idea in most forums on the internet.
I tried to manipulate the fuelling with the push buttons on the PCIII itself, but without result.
Then I synchronized the throttle bodies and that helped a little. I also tried to pull the electrical connection to the stepper motor, but that gave an idle of just over 2000 rpms. No luck there.
Well, to make an already long story shorter, in the end I disconnected the stepper motor completely. I pulled the electrical connection and sealed the connectors with rubber caps, I had lying around in my garage. Then I pulled the two rubber hoses leading from the stepper motor to the throttle bodies. I left the hoses on the TB's and sealed each of them with a bolt and a clamp (to avoid false air from getting into the system).
I then adjusted the idle the "old way" on the two air valves on the TB's using a vacuum gauge.
Did it help then? Yes, it did. I was a little concerned if the engine would start when cold. It does. For the first minute or so, it only just idles, but then revs freely. On the road it runs smoother and seems to be livelier, throttle response and pick up is way better, and acceleration is better and stronger. Vibrations are down and all things equal, the engine seems more harmonious.
As a result, on my favorite twisty back roads, I don't need to shift up and down in gears as much as I used to – most of the time fourth gear will do the job (the gearing on the bike is standard).
The lowest temperatures, I've ridden the bike in, was 10 degrees C (50 degrees F). Under these conditions the bike started and ran fine.
I had a little concern whether the fuelling would be too lean, but it doesn't seem to be the case, and since what the stepper does is to ad air to the TB's, I don't think that will be an issue. Anyway I'm planning to have the bike on the dyno early next year just to make sure.
I have only ridden the bike for a few hundred kilometers after the change, but it seems to be consistent.

Ride safe,
Martin

Martin,
Glad it workesd out for you.  IMHO, the reason the PCIII didn't work smoothly at first is because the O2 sensor sends a variable input back to the ECU instead of a fix value.  That was the problem that RapidBike faced with its 2007 O2 emulator.  Keep us posted on the Dyno run results from next spring!  Good to know that found a work around.

[He Man]

I wonder why Monstermash and NAKID didnt run into that problem.

The 06 S2R1k is not suppose to display the check engien light with the o2 removed, only the 07.

Added to 1st page:

FatDuc O2 Manipulator - Aftermarket plug-n-play that sits between the O2 sensor and the ECU.  It has a dial that allows the user to modify the reading that the O2 sensor is sending back to the ECU.  This causes the ECU to think it is running lean thereby adding more fuel. The effect should only be felt during the closed loop part of the ECU map.  A few people have tried it and are happy with the results.  The cost is only $80.
