Basic guzzidiag tutorial for V11

Recommended Posts

  First, CONNECT:

 

>  Download guzzidiag for the operating system of your computer:

>  Scroll down and download the correct FTDI Driver for a correct FTDI 232RL chipped OBDII>USB cable:

> Connect the 3-pin Diagnostic connector and power the 3-pin > OBD II adaptor with 12 volts through the red (+) and black ( - ) clips.

 

> Connect the OBD II  > USB port in your computer.

> Open the application "guzzidiag" on your computer and click on the upper left "GuzziDiag_VO.44" (or whatever version), select "preferences":

> Select your motorcycle from the drop-down menu.

 

> Important:  select the COM port. As Beetle on Wildguzzi says, "it [the COM port] is usually the last one or highest number. if it doesn't connect at first, keep trying different ports. In my example, I only have one, COM4."

 

>If the selection menu for COM port is blank, physically plug the USB connection into a different port on your computer.

 

( screen shot reference is Mac OS X/ GuzziDiag VO.44):

>  Click on "FILE" and select "CONNECT"

You will be prompted to turn on the ignition. Make sure the "Run Switch" is on and you only use the Ignition Switch (key) to turn on and off during Guzzidiag.

 

If it does not connect, try switching the ignition off and back on. The dialog box in Guzzidiag will read the ECU and its map version when connected:

Once connected, select from "View" : *measurements* and select the sensors you want to monitor. I am most concerned about CO Fuel Trim, RPM, Engine and Air Temperatures:

If your CO Fuel Trim is in the negative double digits, your V11 will never run right.

The engine will have to be to minimum operating temperature (60ºC) to set the CO Fuel Trim by clicking on "View" and selecting CO Fuel Trim (guzzidiag will prompt you while you monitor engine temperature (I like using a fan over the front):

Use the RPM to set your final idle speed and compare to your tach reading. Make note if the tachometer is not accurate, especially when establishing your idle speed.

Then there is this: I have had my Sport on the Axone, VTSTS/pro and now guzzidiag.

 

After these several years, I feel really confident contributing to Bernd Hauser for this excellent tool.

Those of you wishing to go further with reading and sharing maps (.bin files) and writing new "maps" (.bin files) to your ECU should stay in touch with this ECU BIN maps thread in Fileshare:

There are numerous useful links in MartyNZ's post there:

Hi Docc,

 

a faster and much more convenient way to set CO trim is using the EEPROM writer/loader from Beard. No need to start the engine and bring it up to heat, also avoids the need to clear the stored errors first. Program and XDF are on Beard's page.

 

Cheers

Meinolf, thanks for that!  (I believe the factory CO Fuel Trim settings, often in the negative double digits, are one major source of poor running for the V11).

 

Do you have a link for that tool?

Hi Docc,

here you go: http://www.von-der-salierburg.de/download/GuzziDiag/IAW15xEEPROMTool_V0.04.zip

 

And here's the XDF: http://www.von-der-salierburg.de/download/GuzziDiag/xdf/15M_EEPROM_V1.01.zip

So you can or cannot set the TPS using Guzzidiag? Is the ThrottleV what you want?

On a V11, you cannot set the PF3C TPS from a computer. GuzziDiag will only show you the ECU's interpretation of the TPS voltage. If the physical position of that TPS is wrong, then the ECU will have bad data. Then the ECU outputs for fuel and ignition will be sub-optimal.

The TPS is set mechanically by loosening the clamp screws and twisting the TPS to the datum position. See guru Docc's instructions on how to do this here: http://www.v11lemans.com/forums/index.php?showtopic=19610.

And you have to have the special cable to measure the voltage or does that just make it easier?

Just makes it easier. You can stick a couple of straight pins into the harness connector, but that's so gauche.

Here's another great tutorial. While it says it's for a Quota I think they are pretty similar.

A video for setting the CO.

Dave, you set it to -38??

 

John

I am thinking that video was found on YouTube (by pauldaytona) and is for instructional purposes only, not actually suggesting *where* to set the CO, just the sequence of clicks and dropdown menus. I found it a little hard to follow because part of the screen is obscured by the video titling.

 

John, I'm glad you drew attention to it as it could be misleading.
