As a base map before dyno time (due to the 750cc)?

As per former Ducati Svc Mngr[guy in Italy],he told me I can go to 750 with my ECU since my mapping is better and the "street" map will work perfectly with the 750cc conversion, I just want the extra oomph of the DP map for the way it creates the torque and keeps it "flatter" for a few more rpm

Sadly I can only send ECU and engine not the whole bike, we have NO dyno here

So maybe a data logger or on board AFR meter?

I tried the Fat Duc on my 2007 S2R 1000 that has a Full Arrow exhaust system, and while it did improve things, I wasn't satisfied. It still pops too much for my liking on deceleration.  I sent my ECU to Motowheels for a Rexxer re-flash.  I had them disable the O2 sensor and load a custom map for the arrow system. 

When the temps improve I will be testing the re-flashed ECU/map.  I also bought a Power Commander III and installed that as well with the Zero map loaded for the time being.  I figure... If the re-flashed map still needs tweaking, I will take it in for a dyno run and custom mapping.  At least with the re-flash, it should solve the dilemma with  the closed loop, and then I can use the PCIII to fine tune.

Fingers crossed.

Sounds like a good plan. Let us know how it goes.

The temps hit 70 this weekend and I finally got a chance to test out the Rexxer remapped ECU on my S2R 1000 with full Arrow system.  After 3 hours of riding I have to say that I am very happy with the results.  There is no more popping on deceleration with the throttle closed, no stalling at stop lights, and no noticeable flat spots. 

I do still have some popping on deceleration when I do not completely close the throttle (around 5% throttle).  Also, I didn't have the throttle position sensor reset yet.  For those of you with more knowledge about the Power Commander... Can I use it's throttle position sensor reset to override the ECU's now that I have the Rexxer reflash with disabled O2 sensor?  I'm currently running a zero map in the PCIII as I wanted to see how the reflash map ran before considering a dyno run and custom map.

Sorry for not replying. I think you should post this question in the Tech or mods sections. I don't know if the PC tps reset will successfully over ride the ecu but others here should.

Hey LD
I have come to the view that a Rexxer flash is a good start but that getting the PCV dyno tuned is the next step. I would shop around for a good high performance intake kit to go with your full system and get the dyno tune for peak performance. Like many others, I feel the intake mods have a great effect on the AFR so I would not do them without a dyno tune.

Rereading this to refresh my memory. May have an M1100Evo soon and need to revisit this type of ECU tuning.
Excellent info. [thumbsup]

1100 Evo. Track tuning only of course.
PCV with dyno map, Smartmoto O2 eliminators.

O2 Optimisers appear no longer available, but Eliminators are plentiful, so what gives? As Ungeheuer put it, sweet little lies Vs big fat ones. Could it be that Eliminators are clearly and overtly track use only as per the mfrs caveat while Optimisers interfere with the function of an oem component?
For example Dynojet no longer supply Optimisers but provide Eliminators for various models.

That aside, the Smartmoto Eliminators have operated in a controlled test for over an hour without being rejected. Maybe the run needs to exceed 60 miles/100 kms for the ECU to ping the O2 sensors for diag operation? We do know that unplugging a sensor throws a code immediately, so I'm hopeful and we'll see how this goes.
Track time is expensive.

I think he might be doing a lot of travelling and very busy.

Sorry for long post & to rehash an old thread but I am having an issue for the last 5 months and I am slowly losing my mind and its all just to have a quick shifter....

Now I know its not a Monster however I do own a monster along with a few other Ducati's but reading this thread I have see a lot of issue that I believe is connected.

Bike: 2012 Hyper 1100 EVO SP

Fitted with a wasp kit, DPECU, PCV and all was good, bit hard to start and would die unless it was warmed up, but it was good,

Wanted to upgrade to the new 950SP was told I was crazy and the 1100 EVOSP is the best?  But I wanted a Q/S

So fitted Rapid Bike & RB Q/S with CNC rear sets, all was good, infact it was amazing for about 3-4 rides, then ECL came on over and over and was the Vert Cyl o2 sensor?
Spoke to RB they said its strange so turn off the auto adjust and go again, same problem?

Next took off o2 sensors and put Smart Moto 02 sensor Eliminator plugs, bike ran like shit, needed another tune to fix it, bike ran good, like before but not great.

Now ECL comes on again with Vert & Horz Cylinder ECL and Immobiliser Codes??


RB are saying its a Bike Fault and if I swap back to PC5 it will be the same? Im at a loss, does anyone have any help, advice or guidance they can impart?
