Just wanted to wrap up this thread. Finally gave up and took the bike to Todd @ Guzzitech.The ecu map was way off, both in timing and fueling. After Todd reflashed the ecu , the bike now runs great. No more popping and missing,will roll through town at around 2500rpm without acting up and doesn't quit at idle. Also the mid range torque and throttle response are greatly improved. I gave it a 300 mile run out here up through the mountains,out through the desert and back home via route 66 and it ran great. The bike is now a joy to ride. Thanks to all of you who took the time to help me out with this.

how does the ECU map go off? I thought once you have the right flah, you're good to go.

The map didn't "go off" it was probably never right for my bike from the factory. Which would account for the really low miles on the bike , it probably never ran good from new and whoever bought just let it sit . Check out my reply to The Bronze , it might clear up what I meant by that.

Dave, thanks for letting us know. I have the exact same problem so I guess I need that same fix. I've been emailing Todd for a couple weeks now to get the ball rolling.

All bikes are different.No two are/run exactly the same. The 15m ecu isn't an adaptive computer like the ones in the newer cars,it doesn't learn and adjust itself.It is basically an electronic version of jets in a carb. It can only run what has been programed into it.The problem lies in the fact that unlike a carb where you can change the jets to correct poor running, with the 15m ,you can't change it without having the software and hardware needed to work on it.

So back to no two bikes being alike. I have ridden and been racing motorcycles since the early 70's. I also restore and race vintage race bikes. I have built two identical machines,side by side,with the same parts etc. One runs a 450 main jet,with a 42 pilot,and a 6df6 needle, the other bike runs a 420 main,38 pilot and a 6dj6 needle, for top performance. Both will run with the other's carb but neither will perform at its best.

Its the same with our Guzzi's, most fall into the "normal" range and the factory tuning works. However when you get one that falls on the far ends of the "normal" range,running issues crop up. Thats where the re tuning comes into play. To give you the best performance from your particular bike.My bike was on the far end of the "normal" range and so would only run right under certain conditions.

Well. interesting ride home yesterday. I pulled the cyl. head temp sensor and ziptied it away from the engine . Bike ran fine on the way home. I ran some backroads, a 5 mile blast on the freeway ,then onto some surface streets with redlights and traffic. No popping and spitting,no loss of power and it remained idleing.

So, I am going to Ohm out the sensor this morning and again before I head home tonight and note the readings. I will also do a plug check although the bike doesn't appear to be running to rich.If it stays running good, I will take it for a longer ride up into the mntn's and see what happens.

If the sensor is working correctly,would it be safe to assume that the problem lies with the fuel map in the ECU? I don't like running it with the sensor removed as it would be treating the symptom and not the cause.

[04 V11sport loses power and starts misfiring at trailing part throttle]

Dave Im outa town for a week but if you need a test ECU I can send you my 'Race' ECU if you havent found one by them.Anyone who's changed over to the Ti's and Race ECU should have a stock one,so maybe someone will chime in.Mine ran better with the stock one so I left it in.

Thanks, If I can't get her sorted, I will be up to trying that. It would definately let me know if the ECU is faulty or not.

If you go to Moto Guzzi Classics in Signal Hills I bet Mark has a spare ECU you could try.. then you'd know.. He's a great guy.

I'll give Mark a call this week and see what his take on it is.I havn,t been to MGC. I usually use Cycle Garden and get parts from MG Cycle as I generally ride vintage bikes. I am curious to see what happen's this afternoon when I ride it home with the temp sensor isolated from the engine heat. I have checked the fuel line routing and it doesn't appear to be too close to the heads and cyl's to cause a problem from heat soak.Ahh, the joys of owning exotics and the length's we go to indulge our passions!

[04 V11sport loses power and starts misfiring at trailing part throttle]

Hi Dave,Welcome.

I'll just offer moral support here as I believe your on the right track and all the suggestions are good.

Guzzitech is fueling nirvana for most,but agree the bike has to run right ,first ,before going that way.I think they are re-mapping stock ECU's now also Tom,would love to try one but holding off because off multiple projects .

PS I understand not having a Guzzi dealer near you,closest one for me is 60 miles and not a great reputation,so being self sufficient is the way to go for us Guzzi owners and you have come to the right place for help,and most,like 99.9% of us, enjoy and look forward to helping others,so dont let anyone discourage you from coming here again and again with questions.

I can definately use the moral support! This is very frustrating to say the least.As an old wrench turner ,if she had carbs and a std ignition = easy fix. But , learning the fuel injection is fun too. I just hope that the new ECU the dealer had installed before I purchased the bike is not bad, and causing this problem. We will see how she runs today with the temp sensors isolated.

[04 V11sport loses power and starts misfiring at trailing part throttle]

Thats what I am thinking, get it running decently 1st before doing wholesale changes to the ecu. I can,t believe they all run like this from the factory.At least I hope not. I have sent a message to GuzziTech to see what their take on it is,as I am sure they have seen a lot of these.

I am going to try isolating the temp sensors from the engine to see if it stays running good when it warms up. I will also ck the routing of the fuel lines as well.I am also considering the Harley sensors and tps too. I would truly like to figure out what causes this issue.

I still feel its something failing as when I bought the bike I rode it home over 85 miles and even with s stint of idling on the freeway due to an accident the bike ran fine. It wasn't until 2 days later this issue started on my way to Hwy 2 in the mountains.I will tackle it again on Monday.

[04 V11sport loses power and starts misfiring at trailing part throttle]

Thanks for all the input guys. I'm not giving up yet. Does any one have the part no's for the harley parts that interchange? If the my ecu fixes the problem it would be worth it as the bike is damn nice and when its running right its a blast to ride.

I will try the TPS trick.

Theres one for sale close to home and Ive always wanted a Lemans I. How close is this mechanically to a lemans?

Sp isn't a Lemans but is a great ride. I agree with the fairing working great. The bike is really comfortable. I rode over 2000 miles in Utah on mine plus the ride from Socal and back again. The SP has quickly become my daily rider and the 1st choice to wheel out of the garage.

Unhook the air temp sensor and hook up your leads to it. Then put a heat gun about 3' away from it and you should see the ohm reading drop severely. I did this with mine and watched it go from something 1.3 to .3, or 1300 to 300.(I cant remember the readings but it was working really well). I relocated my air temp sensor under the seat by the ECU where its a lot cooler. The bike runs better with the air temp sensor isolated from engine temps.

 

I think the stock map is lean and when you mix in hot temps the sensors lean it out further and cause problems.

I agree that the stock fuel map is lean. Most of the bikes are, from them trying to get them through our lovely EPA. Then you add in hot days and the problem compounds itself.Not to mention Ca's crappy oxygenated gas. If it comes down to that, does anyone know a reputable shop out here in Southern Ca. That could dyno tune the bike and map it correctly ?

[04 V11sport loses power and starts misfiring at trailing part throttle]

Again this morning. Starts up and runs perfect. "At least as perfect as I expect" Air temp out is around 20 C or around 70 F. Get to work let the bike sit for a bit and rechecked the Ohms on the Intake air Temp sensor and it reads 1954 Ohms. and acording to the charts I have it should be reading around 3700 Ohms. So I am thinking the IAT sensor is faulty. Or am I missing something obvious. I really want to get her running like she does in the morning all the time.

Still working on it. But some new observations. Been riding it to work everyday and checking things. The bike runs excellent in the early morning going to work.5a.m. Idles nice, runs excellent. On the way home in the afternoon as it gets hot it starts acting up again. Yesterday out here was about 100 degrees and pretty humid and she acted up again. Seems to be temp related. This bike has the in tank fuel pump not the external so it shouldn't be getting hot. I ohmed out the Intake air temp sensor and accoerding to the charts @38 Celsius or around 98 degrees it should have been reading around 1600 Ohms and instead was @ 1224 Ohms. Does this seem to be too far out of range for the sensor?

As for the gas I run either Chevron premium or Union 76 and have run about 3 tanks through the bike so far.

[04 V11sport loses power and starts misfiring at trailing part throttle]

Ok . a little more clarification. The bike has about 8,220 miles on it,completely stock, no mods. Barely run in. I did check the battery connections,ground wires,reseated all the relays and fuses. I have not messed with the in tank fuel pump and havn't found where the fuel filter is yet. I havn't had it back to the shop where I purchased it from as they won't be open until Tues to talk to them and they are an 1 1/2 hrs away. When the bike is misfiring and popping it appears to be running extremly lean,and it is only on partial throttle/trailing throttle and when trying to idle it along as at a redlight or stop sign. Once moving it doesn't quit but is sluggish and unresponsive but runs ok. As soon as you close the throttle it goes back to surging and misfiring with the attendent popping through the airbox. I was wondering if either the cyl head temp sensor could be bad or perhaps the Intake air temp sensor.As it seem to be self healing I am thinking of perhaps a damaged wire harness or broken wire as the connections all seem to be tight and clean.

[04 V11sport loses power and starts misfiring at trailing part throttle]

Hi All, new here and new to these "modern Guzzi's" so be kind. I just gave in and purchased a low milage 04 Sport from a reputable shop out here. I mainly run vintage bikes." SP 1000" . So Bike runs great on the test ride and runs great on the 80 mile ride home. I give it a good once over and take it for a ride on Sat. morn. Bike runs sweet has a little cough when pulling out from a stop but nothing major or unexpected on a big twin. about 20 miles in the bike feels like its losing power /not pulling as hard and upon entering a very tight off camber corner,on trailing throttle the engine suddenly starts popping through the intake/miss firing badly. Almost went on my head. twisting the throttle open and the bike smooths out but still not running right. Now it won't idle and when trying to run at partial throttle the engine continues to pop through the intake/run rough etc.So after carefully making my way back towards home "at a greatly reduced pace" the bike suddenly starts running right again like nothing had happened.

So after going over this forum and reading the common trouble spots. I give the bike a thorough going over. Check for airleaks,check the tank venting, check the valves, the sync on the throttle bodies,cleaned-checked connectors.You get the picture. I take it for a short run and all seems fine. So head out for a run and on the way home on the freeway you can feel it lose power and it starts popping/backfiring again.On the off ramp agin won't idle and requires judicious use of throttle to pull out from a stop. It wont quit but it dang sure doesn't wanna run.

So I am stumped/confused and regretting falling for the lovely red Italian lady. I am hoping someone here might see what I have missed/overlooked etc. I am hoping for some guidance and wisdom from those of you more familier with these fuel injected bikes. Sorry for the long post.
