Data logger installed. Pretty cool stuff. Best to get a ride in today as a cold front is moving in.

No replies to the throttle body picture? Ignore the text.

I see that the adjustments are conveniently located 

If you don't see removing the fuel tank and airbox as an inconvenience.   

[toytuff]

Nothing is convenient on this bike. Everything is packed tight.

I've had the tank off 5 or 6 times already. Doesn't take long now. 

Long ride today, still looking at the graph. I know this doesn't look right.

cant quite make the temp reading out , looks like 215 degrees C  is that correct ?

[scottly]

Oh, well that was fuel delivery for sure but we will see what the injectors are doing. I still think it's a lean condition and/or air leak. Might be an IAP sensor too.

Without a logger you would drive yourself nuts. You can see a spike in the freeware. (Yellow line) This was the IAP but it could be heat from the engine.

More than likely we will make changes to the eprom especially the fan temp switch. 195 is to high. Need to program that lower. Fuel changes on the high end of the rpm band. She red lines at 12,200 before the ecu says "enough".

Learning everyday, keeps me busy.

That spike in the air temp is very suspicious, as well as the new square wave-forms from several different sensors. My gut feeling as a bad ground.. 

[toytuff]

scottly, this has been discussed too! Many times.  I have checked the side stand switch, clutch switch and kill switch. All good.

Yes, the drop you see is where the bike stalled when leaving out the clutch. (off idle) If you keep the rpm up it doesn't stall. We are thinking fuel.

In this picture you can see where I held it around 5500 rpm in third gear. There was hesitation in the bike. You can see the green line.

We need to check the air/fuel ratio so I'm trying to find some test equipment. (mechanic friend) I might just tear it down and send the eprom off to the UK too!

It's been frustrating to say the least. On the "good" side this bike is wicked fast. 

Thanks for the reply.

Doesn't the bike have an O2 sensor??? Why isn't the logger reporting any AFR numbers? BTW, the air temp looks too high at 60C (140F)?

[toytuff]

The logger does not report that without an additional hardware. (lambda sensor)

I am going to have the AFR read at idle, 15500/2000/2500 rpm when I get a hold of a guy I know that has a lambda sensor.

There is no O2 sensor on the 2007 model. Came out in 2008.

The software is reading Fahrenheit not Celsius.

[toytuff]

At 5500 indicated in third gear we got this. Hesitation.

My friend at the local Yamaha shop lent me this to use. At least I can get some idea where I am. (first pic)

Adam had to change the firmware in the logger. Since he is in the UK and I am in Arizona we used a program called "teamviewer" He basically took control of my laptop connected to the logger and made the changes. TPS in top left, Inj reading in top right and rpm below. Pretty cool stuff.

Picture two (2) shows cold start. You can see the amount of fuel. (top right)

Picture three (3) shows warm up with the injector coming down. (top right) We are looking for 2.3 readings @ 175/185 degrees F. This was just a test on the firmware. I'll run it to operating temperature later when I can put a fan in front and the analyzer in the exhaust.

Before I change anything from the Trim Pot inside the ECU I need to see if it's rich or lean. Since gasoline is 14.7 to 1 (lambda) I need to be 1.000 on the AFR. 14.7 to 1, picture four (4) and five (5). Waiting on some small ceramic screwdrivers. You do not want to use metal! 

Example: Lambda reading of 1.012 equals 1.2% lean. Lambda reading of .988 is 1.2% rich.

Still thinking it's lean. When I remove the fuel tank (again) the first thing is a closer inspection of the throttle body vacuum lines.

the assumption you have made is that when new the bike ran fine but has now developed a fault . i am not sure that this is the case . i suspect the bike has never ran properly and the cure for this will be a bit more than just tweaking a pot . get it on a rolling road and have someone who is experienced with injection systems have a look . was there a later fuel map that you could have installed ?

[toytuff]

I have stated that this problem was from day one. Tuner? Surly you jest, not one within 250 miles that I would trust.

No later maps with the 16m ecu. Just about everybody has had to make adjustments from day one due to the crap factory mapping.

But the bike was not new, right? Mileage??
Didn't you buy it from a dealer? Surprised they are not offering support.

[simon#42]

what i meant was the bike has never run right from the day it was made .
if you knew this why buy it ?

Steve, it was a private sale in a store, not dealer. They did knock some cash off. Basically flipped the bike without riding it. I told them to ride it so as to make sure but who knows. I have spent quite a bit of money from them on the Ducati so you would hope they could be trusted. I have been in the Store many times.

Obviously the bike was not ridden much as I bought it with 252 original miles. I own it, I'll work on it.

Got it...forgot the details.   You'll get there...

[simon#42]

doubt it

[toytuff]

I think so. You just have to go in steps. Finding a gas analyzer to use was a big plus but of course it was more book reading and more time. We don't have emissions testing where I live so I could not find a dedicated lambda sensor to put in the pipe.

Like this forum I'm dealing with some pretty smart folks in another. Once I have a base then I can go further otherwise everything is a guess. It will never run right given the variables.

Once I get a firm afr reading I can start with a throttle plate adjustment, on to the fuel trim then sync the throttle bodies. About all you without burning the EPROM. That will be the last step.

Defiantly a learning curve. The hardiest part is not to get frustrated.

[toytuff]

Get your post counts somewhere else. To far advanced for you.

[scottly]

[toytuff]

Getting a little further on the Brutale. With a bathroom remodel ($$$) and a block wall/wrought iron fence project ($$$) not much time. Mostly morning coffee, me time in the early hours. 

The mid pipe is getting a bung welded in. O-2 sensor wiring routed and gauge wired to switchable power. First picture.

When removing the ECU it was apparent someone was here. Also, the EPROM is not a MV Agusta item that I am aware of. No worries as this can be burnt which is on the plate.

So, we will see where the AFR is sitting. Should be 13.2 to 13.5. May need a "trim pot" adjustment as seen in last picture. (next to the EPROM) From there the data logger and EPROM ship back to the UK for changes and updates. This AFR/ Wideband setup will also connect to the data logger and record AFR readings as well as injection timing, engine timing, RPM, coolant temp, inlet air temp and battery voltage.

To be continued.

Mercy--you need to be a computer expert to work on this new stuff nowadays, glad you got a grasp on it all.

Actually back in 2007 this was old stuff with crappy electronics and even worse mapping. They spent little time mapping the fuel and all that I have read very lean. EPA bull shid. In 2008 a completely different ecu was used. (5m)

Two different models were available in 2006. S model and R model. In 2007 the R was the only offering in the same color. Leftover for model change? Makes sense.

The retail price for the R model in 2007 was $17,995. It came with Arrow headers, mid pipe, race silencers and race EPROM in a separate package shipped with the bike.

What happened to the MVA EPROM? Not here but aftermarket installed which can be burned. (We have access to the original for changes)  Probably a shid map by a "tuner wana be" bozo.

I sent a letter to the original owner off of the title. He moved so it took a month for a reply. He had the  same issue and the so called "best in town" mechanic cleaned the injectors and fuel lines. I had to replace the fuel lines less than a year later as he did not use submersible line.

Other issues also and 13 ounces of oil overfill. Another "bozo" working on a bike. Why injectors? Really?! Even those are suspect. Heck, can't even use the correct size tool on the fuel rail? Really?! Bozo's.

With the help of some great MV forum members and some cash we are getting there.

While some of this may be frustrating, it will be very satisfying once you iron out the kinks. They're phenomenal bikes and resurrecting one to proper performance will be a great deed!

It could be worse; it could be an AMF Harley
