The New Improved GuzziDiag Tutorial

[elrealistico]

I've been using Mark's map for V7III with stock exhaust for a couple weeks now, and it is definite improvement over what mine (18 Special) came with. Much smother power delivery and accelerating, easier starting.
Best money I have spent on the bike so far. Buying the cables is a bit of a hassle, but worth is as well to have the right ones. But now I have a way of seeing what's going on in the engine as it's running If someone can figure out a way of resetting the wrench icon, (without bricking the ECU), the world will beat a path to their door.
I'd be interested to hear from other beetle maps users that have put Agostini slipons on their bikes and NOT deleted the SAS or evap can.

[beetle]

The service due icon (wrench or spanner, depending on your locale) is now exclusively removed by the official service software. It's all done in the dash/instruments software, and we have no access to that. Nothing to do with the ECU.

[elrealistico]

Oh right, now I see where you mentioned that before. Hmm, I will have to see if the local MG sort of dealer or former dealer can do that.

[bald.male]

Thanks for the feedback and answer. Just waiting on cables to arrive and get an afternoon to myself and gonna give this a go. I'm guessing small mods like EVAP removal won't have an impact on results with a beetle map?

No.

Just finished a two-hour ride on the Stornello with the Beetle map - awesome! The stumbling and popping are gone and the power delivery is very smooth. I'm quite impressed! I'm particularly impressed with the low speed usability of the new map, which is nice when I take my poor Stornello off road. In my opinion it was well worth the money!

There were a few stumbling blocks along the way. The first can be summarized by, "I have a Mac Airbook with Catalina OS." I never got V47 or the Reader or Writer to open. I spent about an hour and a half trying all sorts of Mac tricks from this forum and the web to no avail. Luckily, my wife took a lunch break and loaned me her Windows 10 machine and from start to finish I was done during her break. I run Parallels but have had problems with the Apple USBs in Windows and so didn't take a chance trying that route. I did not consider BootCamp.

I ordered the Lonelec cables and they took 10 days to get to Connecticut. No issues. There was a slight delay while I hunted for the diagnostic port (under the seat next to the USB accessory plug.)

The instructions were generally clear and were easy to follow. The throttle position sensor showed 1.2-1.3 which then corrected to 1.0-1.2. I was a little surprised how low the rpm dropped right after starting and thought for sure that it was going to die, but it didn't and quickly idled nicely at around 1400-1500.

I'm pleased! Now I just have to figure out how to reduce the compression damping in the forks...

On Griso.org, the map for Norge GT 8v says GPR exhaust.  What does the GPR stand for?

Do a Google search.  Not that hard!

Okay, my 2004 750 Breva just started running TERRIBLE the first time I cranked it after a 150 mile ride 5 days ago. I am not too smart but maybe I can muddle through the diagnosis with the help of your tutorial and maybe solve the long-standing slow warm-up problem the bike has when the ambient temp is below about 60-deg F. I have ordered the cables from UK.
I have a question: Why does my ECU have a sticker-over-the-sticker? It is mostly unreadable and I would peel it off but thought I would ask first if it means something just that it is there in the first place.

[Kiwi Dave]

Maybe the sticker was added by the importer.

At -60°F, your bike might not be the only thing to slow when warming up.  Do you do 150 mile rides at this temperature?

[vwdsl]

At -60°F, your bike might not be the only thing to slow when warming up.  Do you do 150 mile rides at this temperature?

No, but I ride a lot at +45°F to +60°F and in that range the bike stumbles all over itself for the first 2 miles of riding, alleviated only slightly by full application of the enrichment lever. Much throttle and clutch-slipping required just to get rolling from a stop. But at this moment, that is only a minor inconvenience compared to running on one cylinder with the other only occasionally letting out a loud pop.

Dave.
Did he mean “minus 60 degrees Fahrenheit”
Or
“Below 60 degrees Fahrenheit”
I think the latter..?

That makes much more sense.  Two countries separated by a common language!

Finally plugged my 750 Breva up to GuzziDiag after downloading it and downloading/running CDM21228_Setup to configure port. (I didn't download read and write mapping software because I just wanted to see if I could get any error reports for my sick machine.) I assume GuzziDiag found the port because it only offered one port option. It appeared to recognize what machine it was looking at but nothing else. Bottom left of window said "Disconnected".

So, what did I fail to read, or maybe misread, or have otherwise messed up?

Running latest Windows 10, BTW. This version will not give me a nice, simple way to see what ports are configured. The help for Windows 10 gives instructions how to do it but it just doesn't work in the sequence they give on my machine. (I found where others have complained about this but didn't see where anybody offered a clear resolution to the problem.) After multiple, unsuccessful attempts trying every USB port, starting and closing GuzziDiag each time, the box that shows the comm port went away. Where do I go from here?

[moto-uno]

 If there is an earlier version of Guzzidiag (v4.8) or something like that , try it . I also had similar problems with mine in Win 7 (don't know if that makes any difference)
There was also a selection of ports ( use the down arrow (pyramid) in the comm port box to scroll through them . On my Lenovo notebook it was port #7 and I believe
this came up in a comm port test ( either from the notebook when I originally hooked up the cables or from a comm port test program ) . A bit of perseverance was what
I needed . I previously bragged that it only took me 3 x to get it working . But sure improved the running on my 2018 Eldorado  .  Peter

vwdsl, may I suggest going to the first page of this topic and read Reply #3. I think your just missing something simple like starting with "Preferences".

Good luck,
Tom

vwdsl -- I have found a specific sequence is required to achieve successful connection.  I'm using WinXP (I bought a used computer already configured for GD) and the Lonelec adapter (don't use anything else).  Starting from Ignition Off and GD not started, the sequence is:

1 -- connect the Lonelec 3-pin to the diagnostic 3-pin
2 -- connect the Lonelec Black and Red clips to battery power (I use a separate battery)
3 -- connect the Lonelec USB plug to the computer (you should hear the familiar jingle)
4 -- verify the Lonelec COM number in Windows Device Manager (often COM4)
5 -- start GD
6 -- verify GD shows your ECU model in the bottom left box
7 -- select/re-select the COM number in Preferences
8 -- now click Connect and wait for the Ignition prompt
9 -- turn ignition On, wait 15 seconds, and press Ok

After a few seconds, GD should fill in the bottom left box with configuration information about your ECU.

I recommend as a first step reading and saving a report.  It's very useful to have a printout before clicking on the other stuff GD offers.

In my experience, if Step 9 still shows Disconnected in the GD status line, I have to start all over from the beginning with Ignition Off and GD not running.  Sometimes I'm successful on the first try and sometimes on the third try.  Sometimes I have to swap USB ports.  But I've always been successful.

Interpreting P codes is takes care and thought.  I've seen people saying a specific P code meant you have to replace the HEGO but if you read the service manual closely it wasn't the HEGO itself but rather the wiring for which there was a step-by-step fault isolation process.  Read the manual closely.

Best wishes with your Breva.

     I'm not sure what you're referring to with "CDM21228", if that is the driver software for the chip in the cable disregard my post, if not read on,lol 

     You need a driver for the chip in the Lonelec cable, iirc the appropriate guzzidiag reader driver is needed to drive the chip and make the connection to read the ECU.

     When gd shows no connection, verify all your connections and that the indicator light on the cable is on, showing that it's ready to make a good connection.

     Everyone's experience is different with guzzidiag, but my ports always seemed to select themselves as I worked through the menus and fields, I've had other connection challenges, but the ports have been easy.

     Good luck

The driver you need is on the Diag website I believe or used to be.  My W7 I had to go through device manager in to some properties and I could see where I was plugged in to. Worth researching AND I'm analog but I can still read.

[vwdsl]

Thanks for all the input. It hasn't helped that both times I have tried to mess with this I have been under the gun to move on to something else within an hour after I started. When I get back from my travels next week, I will devote at least a half-day to "becoming one" with GuzziDiag. It prompted me to set the preferences when I first opened it but I indeed need to start at the beginning again.

We (wife) had Little issue tonight when hooking the computer  to my 02 California Stone. At first it refused to connect. After a little research on the issue being on PC windows 10 system we found we needed to turn off “Firewall and virus shields before it would connect. After they were turned off it connected to guzzidiag and all else went well.

I had a heck of a time with my wifes Win 10 laptop!  I ended up digging up one of my old win7 ones. My new win 1o one I got works great though. I think its a matter of if your computer likes it.

I spent much of my working life using computers to access industrial logic, PLCs and such, I hate using Guzzidiag.
I'm using V0.47 on an older Mac Laptop, it crashes with a regularity that makes me think there''s no way I would attempt downloading a map.
The laptop would rather throw itself on the ground than sit on my bike
I find the user interface not very friendly.
Reading alarms shouldn't give me a cryptic message e.g.
P0336 No Signal
P0150 Invalid Signal
P0130 to low (not even spelt correctly)
P1607 Invalid signal
What the hell does that mean, surely in this day and age the computer can interpret these shorthand messages into plain English, that's what computers do best.
One should not have to consult a manual to interpret the alarm codes, at least Guzzidiag should have a lookup file with all the cryptic codes explained
Don't get me wrong, I think the guys have done a great service by writing Guzzidiag, it just doesn't work for me in my situation.

Rant over, ducking for cover.

[Tom H]

Kiwi you'd better be ducking for cover

If you can find software to hook up to a Guzzi ECU that is better, especially for the price, go for it and let us know!!

GD does of it what is asked. Connects to the ECU and allows you to make adjustments or just read the vitals of the bike.

Yes it can be a bit fickle connecting to the bike. It seems some Win versions don't like GD. I guess I was lucky. A laptop and a cheap tablet both worked fine. Though you do have to guess which port it wants to use.

I just want to thank the writers of this program!!

Tom

[Ncdan]

Oh yea, one other thing we had to learn the hard way snd by chance. Hooking GD up to my 2002 Stone w found not get it to connect to GD. While wife was trying every thing she could think of with the laptop aspect of the process I was fiddling with the bike. I figured I’d go ahead and put it in neutral due to having to start the bike up later in the process and low and behold, instant connection!!!
The tranny must be in neutral for what ever reason. We did I’d over again to make sure that’s what made the difference and it was!

Dump that Apple crap and get a real computer ..... <now I'm ducking>

I also thank the Guzzidiag team, a great resource!

I don't have any allegiance to a Mac. they do some things well.
Are you telling me the "PC" explains the alarms better?

That should be explained if it's the case, I know it's free software but I would be willing to contribute if some of the issues could be addressed.
My biggest beef is computers do so well at documenting and it's not utilized, ok, it might be hard to display the alarms in plain English as part of Guzzidiag but a Word file is something almost anyone could create, it doesn't even have to be part of the software package.
Anyone have a word file for the V7 alarm messages.
One of my problems is I cannot from where the bike is parked go on-line to find the manual so it's jot down the alarms then go and look the codes up.

[Yo Man]

I have two Mac laptops-versions 10.13.6 and 10.14.6. I'm also computer challenged in the extreme. Any ideas on which version of Guzzidiag would work with either of these two laptops? If it matters, the bike in question is an '09 Stelvio. I have managed to use version 4.7 using a borrowed PC but can't get it to work on my Mac. Thanks.

[Dirk_S]

Email Mark--he'll provide you a Dropbox link to download version 4.6 which works with Mac OSX Catalina.
