The CF mufflers I have lying around look fine. No scratches or anything but if I recall correctly one of them has a very small leak somewhere. If you want them I'll be willing to sell them for a small price.

I think I still have a pair of CF mufflers in my garage. I'll check them this evening to see if they aren't damaged. I live near Rotterdam.

I used my digital multimeter to find the faulty wire going from the ECU relay to the ECU that didn't allow the bike to start.

Thanks Scud ! I saw that and I'll make me one and try that first. Could save me a lot of work.

Yesterday evening I walked up to my bike to replace the leaking head cover gasket and found a puddle next to the frontwheel which wasn't there yesterday morning. More leakage ! I just ordered new seals....

Solved but subject to further investigation. I received a map from another dutch Guzzi rider for a 15RC ecu with the lambda probe 'switched' off. After several fruitless tries I was advices to reset my laptop before writing the updated map to the ecu and that did it ! After this the CO trim had a vlue of 0 in GuzziDiag and I had no problems changing and storing the CO trim. Thanks everyone for your help.

Must I load my bin file together with the 15RC_GuzziDiag_1100_V2.16.xdf file into TunerPro and un-set the "Lambda Control" flag ? Then save to a new bin file and write that to my ecu ?

How do I 'turn off' the lambda input ? In TunerPro I can only see the "CO-trim" and "Enable CO-trim" options.

@docc, As Gelos advised I used TunerPro to change the CO-trim setting. But instead of using the IAW15xEEPROMTool_V0.04 software with an EEP file which won't connect to my ECU, I used IAW15xReader_V0.67 and IAW15xWriter_V0.26 with BIN files which does the same.

Instead of trying GuzziDiag again I went for the Tunerpro solution but unfortunately this also did not work still leaving me with a CO level of -128. What I did: I used IAW15xReader_V0.67 to download the ECU contents into a bin file. Then I used TunerPro with my bin file in combination with the 15RC_EEPROM_V1.01.xdf file to change the CO level and saved this to a new bin file. Then I used IAW15xWriter_V0.26 to upload the new bin file to the bike. During this process no error messages were shown. I followed the instructions and only messages stating everything went fine were shown. Then I connected GuzziDiag again but this was still showing the old value of -128. I tried the whole process from beginning to end for a second time double checking the steps and my actions but the result came out the same. The TunerPro logfiles confirmed my changes. I'm also sure I uploaded the new bin file and not the original one I saved from the bike. I went back to the GuzziDiag method again and heated up the bike to almost 100 degrees celcius and tried to change the CO level with the - and + buttons again but the Finished button just won't respond. I also don't get that message any more saying I have to kill the engine with the kill switch which I did get a couple of days ago when I first tried to change to CO level. The IAW15xEEPROMTool_V0.04 software throws a can't connect message when I try to use it so instead I used the separate reader and writer sofware. Is there anything else I can try ? Thanks !

I just got back from a short ride to the gasstation and 5 minutes after I got back and read your posts I went back to the bike and checked the engine temp. After 5 minutes it was already down to 63 degrees so no luck. I'll try again tomorrow and see if I can heat the engine up to at least 75 degrees and try again emediately after I get back. With GuzziDiag I actually tried all the bikes listed and only the bikes with the 15RC ECU seemed to work with my bike.Which corresponds with the sticker on the ECU.

Hi Docc, The picture shows a 'cold' reading. When the engine is to cold for setting the CO level GuzziDiag wont allow access to the CO level adjust screen and shows a ' temp to low' message. I warmed up the engine before trying anything else.

My 2003 Le Mans is running terrible and I'm looking into setting up the bike according the different procedures found in the Technical Topics section of this forum. While connecting the GuzziDiag software and having a good look at the faded letterings on the ECU I discovered that my bike doesn't have it's original ECU fitted. I'm not sure what ECU the bike came with but it now has a IAW 15RC PF3C from a California MY03 CAT fitted while I don't have a lambda probe on my bike. While all the different GuzziDiag screens and functions seem to work I'm having trouble setting the CO trim level. After increasing the -128 (yes, -128 !) value with the + button and clicking the Finish button nothing happens. The screen doesn't change. I can only press the - or + or Finish buttons. This made me wonder if the CO level can be changed on a 15RC CAT ECU while my bike doesn't have a lambda probe. Any ideas about what I can do to change the CO level with the 15RC ECU without the lambda probe ? Can or should I fool the ECU in thinking there's a lambda probe present ? Thx ! Walter

Thanks for this magnificent post Troutman ! I'll be getting a different speedometer but your solution for the sender cable is what I was looking for !

I suspect a Ducati.

Finally went for that first ride and it was great ! There's still a lot of work to do on the bike but at least I can ride it again !

Maybe you can try the (very) cheap alternatives on AliExpress.com. Search for Moto guzzi v11

After being parked in bits outside under the carport for almost a year I finally fired up the bike this weekend. Just when I was going to go for a ride fuel started dripping on to the ground. The fuel lines were completely dried out and cracked! Also the quick-release couplings I installed two years ago were leaking from the inside ! So no ride just yet !

Thanks Frey. My bike doesn't have the pads and I thought the pads were laid in a depresed section of the tank.

Looks nice ! How did you fill and repaint the deepened area ?

Yeah, that's a girl in the background. Not to sure about the rider though !

Wow ! Very nice !

N'ice docc !

Love the scenery and those roads ! I realy live in the wrong country !

Sure Docc. Due to having no time at all and having to work outside under the carport progress is slow but if there's anything to post I'll post it in the Custom Seat thread.
