GuzziDiag HowTo - A tutorial for beginners

[Vasco DG]

Have you got the cables and software? If so PM me your address, I've got to fire maps off to a couple of people this afternoon, I can easily bung the latest iteration your way.

DO NOTE THAT THERE ARE A VARIETY OF MAPS FOR THE G8 THE COMMONEST ONE IS THE ONE BUILT FOR A STOCK BIKE OR ONE WITH A SIMPLE AFTERMARKET CAN WITH A dB KILLER AND PREFERABLY A CATALYTIC CONVERTER, ALTHOUGH IT WILL WORK WITH JUST A dB KILLER. IT WILL NOT PERFORM OPTIMALLY IF YOU HAVE AN OPEN PIPE AND A ROCK STRAINER IN PLACE OF A PROPER AIR FILTER.

Mark has developed a few maps for different pipes as they all have slightly different requirements but obviously to do individual development work requires access to a machine so equipped. The 'Basic' stock/dBk/CC map will work reasonably and safely though as long as the air filter hasn't been screwed around with. FWIW there is very, very little, if anything, to be gained by changing the filter and it opens a can of worms WRT fuelling at certain points.

Should the O2 sensor be removed if it's been turned off , Don't they get carbon'd up if not in use ?

I didn't bother removing mine, and it never got chogged up. I never checked, but I suspect the heater stays operational even if lambda is switched off. When I pulled it out, it was clean as a whistle after more than 6000km.

Ok good to know, I suspected it was still powered
Vasco, if got a stock air filter system, an aftermarket pipe with a db killer fitted, no cat fitted.
I've managed to set up all cables and software, also in the process of hooking up an innovate LM2.
I'm not chasing any extra performance but maybe some gain in fuel economy when at highway speeds.
Pm'ing address cheers

Thank you guys for this write up! It has helped a guy who can rarely find all the keys on the keyboard (me) make sense of this awesome program. ;-T

Has anybody had much luck with finding v11 Sport maps? I am in my experimental phase and would like to see what's out there.

Thanks Bill

[Waterbottle]

Received the map, thanks guys. It definitely made an improvement.
Smoother throughout the rev range.  
It definitely idles better.
  And, I,ve only done 50 km on the new map, but it looks like it might be around  1/2 a litre per 100 km better on fuel( City /Hwy combined) That's another 15 Mins riding between fill ups.
It doesn't sound like much, but this one time , in band camp , I had to push a bike............
A new exhaust and more testing to follow. :bike

I don't see the exe file for the drivers. What am I not seeing?

[beetle]

Were did you download the drivers from? If from the FTDI site they will be zipped.

Download the very latest drivers:

http://www.ftdichip.com/Drivers/CDM/CDM%20v2.10.00%20WHQL%20Certified.zip

Unzip them, but do not install. Plug in the cable to a USB port and when Windoze tries to install a driver, point it at the directory where the unzipped drivers are. After the install is done, try connecting to the bike. Make sure the fly leads from the 3 pin adapter cable are connected to the battery.

[Hellgate]

Thanks Beetle! My Windows 8.1 machine was a little obtuse. On my Windows 7 machine it works much cleaner.

I also think I ordered the incorrect cable. I've got another one come for Saturday.

Thanks again!

[pauldaytona]

There also setup un exe shape available:

http://www.ftdichip.com/Drivers/CDM/CDM20830_Setup.exe
http://www.ftdichip.com/Drivers/CDM/CDM%20v2.10.00%20WHQL%20Certified.exe

Run these before you connect the cable first time. Bottom one is newest one, and windows 8(.1) gets this from windows update too if you let windows get the driver from windows update.

I ran into an issue today on a Bassa. I've had this happen before, but today I found a 'fix'.
I tried to set the idle trim. For some reason, this bike was at -94. Nothing I did would change the trim, it stayed at -94. I fired up my old VDSTS software. Same thing, stuck at -94.
I was doing was following the software instructions to set the trim. After changing the value and doing the shutdown, I was waiting 30 seconds or more before starting up GuzziDiag (or VDSTS) again. But when I tried unplugging the 15M during the shutdown to totally shut down the ECU. That worked every time. Odd.

Not sure if the power cycle was clearing something or what was going on, but if you have trouble setting the idle trim, pull the plug on the ECU after it has powered off.

[Hellgate]

Paul, when I try the links you provided I get this message, "This Operation Requires Elevation." 

I have the 2.10.00 driver installed. I can't get the pc to talk to the ECU. Uninstall, reinstall, reboot, etc., etc.

I printed the FTDI users manual too, no luck.

I give up.

[beetle]

Paul, when I try the links you provided I get this message, "This Operation Requires Elevation." 

That just means you require administrator rights to complete the install.

I have the 2.10.00 driver installed. I can't get the pc to talk to the ECU. Uninstall, reinstall, reboot, etc., etc.

If you have v2.10.00 drivers installed, you already have the latest drivers. They are the same drivers in Paul's link.

I give up.

Don't do that!

First up, try the test tool to see if you actually have a connection: CLICKY

If that fails and the drivers are installed, then it can be either a bad cable or something in Windoze (firewall, virus software) stopping the connection.

[pauldaytona]

Pete,
the cables you have do have the 232rl chip?
The led on the adapter is on when connected to the bike?
What Bike?
If you go in device manager, and goto the com ports, when the usb is connected to the computer, what do you see as driver at the highest com port number? That should be the ftdi

 just like this, this is win 8.1

[pauldaytona]

Wayne,

Setting Co, is working only if there are no errors, and tps value is in range. When tps is to low, it won't work too. I suppose you have that right so that wouldn't be the case. These are conditions the 15m software defines, not guzzidag, as you see that vdst won't do it too.

I'm thinking that there was an error in memory that I didn't notice. By pulling the plug on the ECU, I was clearing the memory.

I know you don't think the 150mv setting is important, but is that what Paul is saying?

and tps value is in range

Certainly no offense intended...

[Hellgate]

Thank you.

This is with my 2013 Stelvio.

I've turned off my firewall and antivirus, verified the driver via device manager.

I'll open up the cables to verify the chip.

Stay tuned...

[Vasco DG]

Peter, it really is worth persevering. While I haven't actually experienced a Rexxer mapped Stelvio the G8 I rode that had a 'Stock' Rexxer map was blubbery-rich all over. Whether this is normal and the result of the tuning process or an aberration I can't say.

[canuguzzi]

What a thread. Learned so much right here. Thanks so much! ;-T

[Hellgate]

Here's the chips from the two cables I have.

I am now really question what I received from Amazon as both layouts are completely different and none of the chips are 232rl. At least I recognize the Ti logo on one of them...

Thoughts gentlemen?

The good thing is, with Prime, I got them for $9.00 each in two days.

[Hellgate]

No kidding!  :D

[Hellgate]

I went ahead and ordered this cable set from the UK that is specifically for GuzziDiag. Pete had posted this on the AF1 site a couple of weeks ago, however I'd already ordered the cables from Amazon.

No. I was at 3.6 degrees as required. (3.58 actually if I recall.) It was the clearing of memory that enabled the throttle trim.
And yes, going through the 150mv setting is goofy IMHO. You never see anyone with a CARC bike doing that.

[beetle]

Hellgate, that cable is no good. But you obviously figured that out. :D

You did right ordering from Lonelec. I've updated the first post in this thread with a link to their kit.

[pauldaytona]

first cable has a chiphead 340 chip on it. They might mwork if you connect pin 4 and 5 on the big black connector. But needs the 340 driver too then, if windows didn't find that self.

Amazon cables are mostly wrong. 

[Jukebox]

Hi Hellgate
I ordered the cables Mark (Beetle) posted and all good.

[Hellgate]

Thanks again everyone!

I was just telling the things I know that make that you can't set CO. 
A carc (excluded the bellagio) has a linear tps that you can't adjust mechanically. Only with reset tps from diagnostics, that marks the throttle closed as starting point.

[Birch71]

With all the stuff out there on the 8v Griso, has anyone done work on the 2v?

I still have the stock can, but might go Arrow or the GuzziTech underside can.
