M696 tuning issue. 02 error... Need help/advice

[Veloce-Fino]

Finally got ECU back from desmoworks with the reflash. Installed it today and bike ran perfectly fine. All the other issues I had experienced were eliminated. Thank god

Great News! I bet you were tearing your hair out during this whole ordeal.

I'm still curious why the ECU could not adjust the closed loop to solve the lean issue.

I had mine reflashed and 02's deleted by Anthony also. Let me know if when you unplug and remove the 02's you pull a code. I have not removed mine yet because, well I'm lazy.

Im not an expert on the ECU but aren't there pre-set parameters for the ECU in closed loop as far as the A/F ratio and it won't adjust? I think the ECU was getting a funky signal from the o2 sensors once they reached 300 degrees(when they turn on) and the ECU was throwing a code and trying to fix the problem some how.... Who knows. It could have been something as simple as a crossed wire, damaged o2 sensor, or maybe even the different mid-pipe I had for my exhaust... It's beyond me..

I took off the o2 sensors and ran the bike for awhile... No codes. I bought two oil drain bolts for 2 bucks each. They are the same size as the o2 sensors. We put those in the space where the o2 sensors were and they worked very well in plugging the existing holes.

So, tuner has the bike over the weekend and hopefully I will have it back in running shape by next week!

ups, got it late, but it only makes sense that installing pod filters will make the mixture way lean, the o2 sensors will go way out of it's pre-programmed parameters or comfort zone (because is way lean) and the ecu will think that the 02 sensor is faulty due to the milivolts output from the sensor beeing out of range.
glad your bike runs fine now!

So how come mine worked fine?

@Ung:

Aren't you running stock mid-pipe and slip ons?  It is entirely possible we had the O2 sensors wired backwards- we were never able to get a straight answer on what "O" and "V" represent to make sure which one was which.  If that were the case, it WOULD be causing the condition described whereby the ECU was adding fuel but it wasn't changing reading properly at λ so it was adding even more OR the reverse, it was attempting to lean the mixture coming out of closed loop and since λ wasn't detecting the change was attempting to lean even more and creating a VERY lean condition.

Either way, the combination of a λ CEL and the fact that removing O2 from the ECU fixed the symptom, it had to have been something with those- since we based how we had them hooked up on the PC instructions I'm not entirely sure we didn't have them mixed up.

Could the difference be as simple as the closed loop and stock maps on 1100 ecu are richened up for the added displacement and other features of that engine VS the 696.  I still haven't heard anybody chime in who has actually done the mods Brian has and what their results are so we have nothing to compare it to...

Also, Ung, didn't you have a DP ECU before doing the install of everything? That would certainly have a richer base tune.

It could be a whole array of things causing the error. But, got a call from tuner and he said it's running good and it's all dialed up ready to go, so whatever the issue was, it was fixed with the ecu reflash. Can't wait to ride! It's been way too long

Do you have any dyno results?

Do you have any dyno results?

+1 interested to see if the exhaust we have combined with the intake makes around stock #'s

Remember, the HP/TQ #'s Ducati states are probably mildly exaggerated. Maybe 1-5 HP/ft-pd

No results yet. Just spoke to tuner briefly. He has a lot of experience tuning(30 years) but mainly on harleys. We will see this week what the numbers are.

Same number of cylinders, should be fine.

I did have DP ECU correct.  But M1100 DP ECU's retain the stock closed loop and O2s still aim @ 14.7:1 AFR, neither richer nor leaner than with the stock ECU.  Same on M696. 

Since there's uncertainty about whether the Lambda connectors (and therefore maybe the Dynojet Optimizers) were correctly orientated (coulda been bass-ackwards), I'm putting my money on that.  Anyway, doesnt matter now since the reflash deleted this issue  .

Ever get those dyno results?
