Big Help Needed Badly. 999 CPU HELP
 

Hi To All
I bought a secondhand system for my 999 bip back last year. Pipe, CPU And the end can and filters. Fit the end can myself and had Ducati fit the CPU and the race filters all fitted on the first service. Bike working just great. Today the bike had the second service only to be told that the CPU for the race system is now playing up. Front cyclinder gets to much fuel 8% should be 6%. So i now need a replacement CPU. I can get one under warranty but to get one i need to get a recept for a Termigoni Exhaust system kit with CPU. As because i bought it secendhand i had no recept. I have tried to get in contact with the person i got i from, as i found old e.mail. The recept needed to be from last year as Ducati fitted CPU on the 16-7-2004. so if you can help me with this one, it would realy help me out. I would only needed to show it to the dealers then you could have it back. Don't worry about the name as we will say it was bought as a presant. if anyone can help with this or give me some other advice then i will be very greatful.(beers will be paid for!) Please respone in here or U2U if you would like.

Has any adjustment been attempted or has it just been measured that the front is over fuelling?
The fuelling is adjustable via the Mathesis tester or via software and the balance between the cylinders can be adjusted via the air bleeds............
If the bike is still running, then it'd probably adjust??

I think adjustment has been attempted as they told me about the 5 or 6 deffrent settings. :( I am so p***** off. The bike is running like crap now. Open the throttle wide and it just gose nowhere. Im think of jumping from the motorway bridge.

Something sounds not quite right here , 'tis a well known fact that once a race ECU has been fitted to a bike it will only work on that particular bike , are you sure they fitted the race ECU ?

It is possible to make a bike run fine using an asymetric system (which yours sounds like it is) using the standard ECU by altering the mixture settings using the external diagnostic computer (my 749R is running exactlt this) , it sounds like your dealer has not fitted the race ECU (as the bike would notrun at all) and incorrectly set up the bike afterwards.

Have a look at the ECU yourself and check exactly what is there first , the label on the ECU says bike model and if it is a race unit or not.

It is the race CPU fitted

whoever fitted it must have done something to it to make it work then , and it sounds like it has gone wrong , good luck

So before the service your bike was running fine?

After the service it runs like a dog and now needs a new/replacement ECU?

Am I missing something here?

I do not know how true it is but i was told by a couple of dealers that the cpu from any race kit can be exchanged from bike to bike without any problems but a standard cpu cannot and is specific to the original bike that it was initially fitted to ?

You say got filters, do you mean aftermarket air Filters?

Undertank air filters are not as good as those in the standard position for throttle response and can upset the fueling on the older models, e.g. 998

the standard and race (hi flow) air filters on 749 / 999's are in the same place , as the air tube enters the airbox , the only difference is the filter material , the race filter has a more open mesh to let more air in.


in reply to iang's post , my local dealers first experience of ECU 's only working on the bike thet are originaly fitted to was when a customer who had an 03 999S mono and fitted an assymetric system and ECU to it traded the bike in for an 04 , 999S bip model , he asked for the exhaust etc to be swapped over to the new bike , the dealer did si and the bike would not start at all , they put the standard ECU back on and it started straight away.

u2u

When I bought my 57mm system dealer told me I could run bike without race ecu if I wasn't bothered about an extra 1000 revs and they made sure fueling was OK. if they coded the ecu to my bike it can only be done once so you can't sell the system with that ecu, it would need a new one. They also said it was possible to install the race ecu without coding it but I'm not certain that works

Interesting this. I was told by Ducati Glasgow that the key is coded to the clocks and that you can change ecus without any problem. They also said for regular road use the Termis (on a 749 anyway) worked best with the standard ecu rather than the race ecu.

Lastly, if you cant get a receipt, why not get a PC111 and sort the fuelling that way. On Ebay they go for about £150.

Hope you get ot sorted, but as others have mentioned I reckon its got more to do with the "service"

Even more interesting it was the mechanic at Ducati Glasgow who told me it was ecu. They did say the same abut the race ecu not always being best for road riding as its set up more for higher rev riding, I wont fit mine till i can afford a PC3 and dyno time which won't be this month as i need tyres :(

I'm sure that the fueling and CO2's can be adjusted independent of the ecu. I too have been told the std ecu works better and helps eliminate cutting out.

I've got a receipt but it's 2003 if it helps.

Thanks to all who have responed to this call for help and i would like to say that someone in Ducati has read this post and is not happy :( with me ! I thank you all for your help but please don't write any more on this posting. If you would like to U2U me then please do so.

Does anyone know where i can by a Hayabusa you don't get these problems with Suzuki Bikes Only Playing! :lol:

Well whilst they're reading this perhaps I could add that I don't like having a bike that cuts out at junctions, a bike that their official dealer can't provide a front indicator bulb for and a bike where the speedo goes into warp drive and has a mind of it's own. :devil:

So there!

Nice Very nice

Then again, maybe they shouldn't be reading this and get on with chasing real issues the concern their customers and dealers.

Had the same problem with cutting out was told "we will sort it out at the first service" That is really shoddy IMHO. No doubt I am not the only one to be caught out with a dead motor half way cross a roundabout with a truck looming.

Then there are Twinfans brakes. No doubt any number of other issues that could be being addressed by the folks at HQ instead of browsing these boards.

Or am I wrong? Do they read these boards and act upon what they read?

From their point of view it is excellent feedback about there product but you do wonder if they act upon it.

I had a similar issue with my Aprilia. Very long story. Any how in the end I resorted to ****ging Aprilia UK off big time on the two main Aprilia websites knowing they lurk. I get a call on my mobile offering me some Aprilia gloves if I'd stop. Never got the gloves either. The up shot was that at least two people didn't buy an Aprilia as a result of my posts.

So under estimamte the power of the web at your peril.

All i want is a bike i can use and not just look at. Not to much to ask for £12000

My oh my:o

How many times has that question been asked on this board previously?

Ooopps, sorry. Gotta be positive about this.

Well at least you have the Kudos

I would just like to say here that my 999S did 4k miles in a year with zero problems , ridden in all weathers and thrashed most of the time other than the first 600 miles.

The replacement 749R had done about 5k miles now in 15 months and has also had absolutely zero problems , again ridden in all weathers (most of the running in was in the rain) , starts first time every time , runs great , kicks ass and brings a smile to my face every time I look at it / get on it / start the engine / clean it.....in fact , you name it , everything about it makes me happy :D

oh , I forgot to say , maybe it's just me :saint:











or maybe it's just you :puzzled:

is your bike standard or not

For every good one there is a duff one. Point is when there is a problem all you want is action. This is where they have a lot to learn. Everything is great when it's running well.

Nope,Ive had two 999's,standard and 'S',both have been good as gold.:)

My 999S had a 54mm full system fitted inc race ECU , filters etc , ran perfectly.

My 749R has an assymetric system fitted , also high flow filters , it's running the standard ECU , runs perfectly.


:bouncy:

Hi All
Bike went in on Sat afternoon. So they could replace the race ECU with the standard one. After fitting standard one, the bike still ran like a dog. So they started looking into other things. The bike then spent the weekend in the dealers (they did loan me a ST1000 if you like they type of bike) So in the end the Ducati fitter found an air leak on the front rubber where it bolts on to the head. Rebuilt bike run with standard ECU all ok. Run then with the race ECU and every thing worked fine. Had the bike back yesterday but had no time to run it so i will be out tonight to see if every thing is working as it should be. Thanks to everyone with your responces it has made us smile when we felt low. (ttstu your one was the best)
