EXVL Error Code

[oldndumb]

On a related note. Methods of disabling/removing the exhaust control valve still leave the butterfly and shaft blocking a portion of the pipe. And the story that the valve spring will position the butterfly open/parallel to the gas flow is not accurate. The valve spring positions it approximately 10 degrees from full open. And the size of the shaft, which I did not bother to measure, is approximately 5/7 Mm, adding to the blockage.

Not to say that any of this is significant to the casual rider, but those seeking bragging rights might consider removing the shaft and butterfly in addition to the motor and cables.

Which is precisely why Raux is suggesting this:

And 696 midpipe

[oldndumb]

Bear with me as this is my first Ducati. It is a 2012 M1100 EVO.

Will the 696 pipe fit all applications, or should it be recommended with model application specifics, or is an assumption implied?

[Raux]

The 696 midpipe will fit the 796 and 1100 pre evo
i haven't heard anyone putting non evo exhaust setup on an evo
but likely could be done

or just disconnect the motor cable and leave the electrical harness connected.  No more errors.

Well, this didn't work! Now I get an error code immediately upon starting the bike.

Here is my concern, SOMETHING is telling the ECU that SOMETHING is wrong, or the ECU thinks that something is wrong. There are only two pieces to the puzzle right? The ECU and the motor. If the problem is the motor itself then I can replace it with a DUC.EE and be on my way, however if the problem is the ECU itself then I have a larger problem, right?

I may have access to a different motor, I am going to see if I can get my hands on it and try replacing my motor with the other motor. If the problem goes away I'll simply buy a DEC.EE and be done. But if I replace the motor and STILL have the error code then do I consider that my ECU is having a problem?

Unsurprising. I was surprised to hear that it would work (although I dont doubt those who report FHE that it did work for them - I just dont understand how).

1) You could have a defective servo motor (possible but unlikely IMO).
2) You could have a defective ECU (possible but even more unlikely IMO).
C) The flapper gate itself could be slightly sticky and fail to return "home" in the expected timeframe (possible, likely? Maybe) .
4) The operating cables which transmit the Servo motor drive to the exhaust flapper gate could be out of adjustment....  (most likely IMO).

Swapping out the servo motor for diagnostic purposes would be a minor PITA (and may still be inconclusive if the operating cables are out of adjustment ).

I have a DUC.EE for '09 M1100s sitting on a shelf in my garage.  You're welcome to borrow it for testing purposes, but its not for sale... I'd like it back.  Only issue is postage.... I'm in Australia... so take a week or ten days to get to you....  Anyway, if it's any help the offer is there.  Lemme know.

^^truth^^  The 696 midpipe only solves 1 of the 2 problems with the new gen midpipe (excluding evo) - I've dissected and examined the innards of the 796, 696, and evo exhaust.  The evo exhaust design is much improved from the earlier design in terms of transitions/flow. I'll just copy and paste a post I made on the other forum in regards to the this topic...

The flapper does indeed default to the "open" position but the flapper is thick and does not quite sit parallel to the exhaust gas stream in this default position...hence impeding flow even when "open". I would estimate the flapper reduces the exhaust channel area by 25% even in this "open" position. In addition...the internals of the midpipe are just horrid in general: jagged pipe transitions, poor welds, and merges that jut out into the exhaust flow causing excessive turbulence and poor flow. Our midpipe is a major bottleneck and installing just slipons does little to remedy this. The craftsmanship of our midpipe would be embarrassing on any bike, let along our exotic Italian steeds.

The top arrow is the worst part, kind of hard to see in the pic but that is the point that splits out into two after the flapper - there is lip that juts out a good .25" on both sides on 180 degrees of both joints. Terrible.

Bottom arrow is the entry point from the vert cylinder - looks like a blind Italian with Parkinsons put these midpipes together...

I agree... internal pipe joins on both M696 and M1100 (no FHE with 796 or EVO) midpipes is awful. 

But awful without internal flapper gate (M696), has got to be less awful than awful with internal flapper gate (M1100?M796), no?

[Mhanis]

Ung, I appreciate your offer, that is very generous, thank you. At this point I don't think it necessary to go through all of that. The DUC.EE isn't THAT expensive so if it looks like that will help I'll just get one.

But, check this out: My last post was upon arriving at work yesterday. I started and stopped the bike a few times before posting and the same thing happened every time, the error code popped up immediately. When I left after work yesterday, no error code. I stopped to meet a buddy and started the bike again, no error code.

Rain today and tomorrow so no riding but I'll start it again and see what happens this afternoon.

I hate this kind of electronic problem shit with a passion.

Correct^^.  The ideal solution however is a proper full system - I haven't looked at the internals of the full termi or arrow systems but I assume they MUST be better than the stock internals.

I would take this as an opportunity to just reflash the ECU and optimize the fueling on the bike, you can deactivate the exhaust valve and O2 sensors at the same time killing two birds with one stone.  If your going to spend $150 on a Duc.EE you might as well spend another $100 and get a better running bike, maybe another 1-2hp, and you get to eliminate the bulky exhaust valve motor from the bike all together.  Win-win.

[Mhanis]

Storm,

That is also an option but I have always kicked around the idea of velocity stacks or something of that sort and I do not know exactly WHAT I want to do yet.

It is hard to do SOMETHING when I don't know exactly WHERE I am going in the long run.

Does that make sense?

Just a quick update:

After getting error codes on the first day after simply disconnecting the cable I have not had one pop up since.

Mark

[Mhanis]

For some strange reason after not showing the error code for a couple of weeks after disconnecting the cable I started the get the error codes again!

I talked to a buddy who had a motor sitting around after switching a full exhaust; I installed his motor (without the cable attached) and no error codes for about 2 weeks. It seems that the error code may be coming from my valve motor. I am going to keep it on a few more weeks, if the error code stays off then Ill get a .ee and be done with it.


Mark

[Mhanis]

Someone smarter than me needs to help me out here; after NOT getting error codes for a couple of months they are back!!

My current configuration is this: I still have my buddies valve motor attached to the bike but the CABLE attaching the motor to the valve is NOT connected. Here is the kicker; the error light is coming on when I am at highway speeds doing between 70 & 80 MPH. Shouldn't the damn thing be doing NOTHING at that point? I am going to try attaching the cable this week sometime but I don't see how that could possibly make a difference.

I emailed Motowheels a week or so ago about a duc.EE and have heard nothing back from them.

 

I have an extended warranty on the bike but if I bring it in what would the dealership do? I would think they would suggest trying another motor but I have already done that!

Mark

[ungeheuer]

Mhanis.... be logical.

You were getting EXVL error codes.

You swapped out your servo motor for another servo motor from your buddy.  

You're still getting EXVL codes.

It's NOT the servo motor.

If you take it to your dealer, they are gonna tell you that you are getting the EXVL code because you have the bloody drive cables disconnected.  They will fix it by reconnecting AND correctly adjusting said cables.

Others have said that they were able to disconnect the servo drive cables and got no error code (for how long did they trial this?). I really don't understand how that is possible (which is not me calling BS on their claims, I just dont see how its possible).  

Meanwhile here's you running your bike with the flapper gate servo motor and its drive cables in a state of failure (you have it disconnected!!) and you're wondering why you're getting EXVL error codes  

Just buy the bloody Duc.EE and resolve the issue.

Motowheels?   Mark at MotoCreations maybe?  Although I think maybe his cat died, he seems pretty slow at getting back to people lately.  Or Jeff at Monsterparts was stocking them for a while too....
