This is a basic howto for the GuzziDiag suite of tools. This howto will show you how to connect, read (backup) your existing map, write (flash) a new map and perform a TPS reset. This uses the Windows versions, but Mac & Linux versions function the same.
All types of ECU use the same version of GuzziDiag
I've created a PDF version of this tutorial. Download it from my drop box here: LINKY
Click on the link for your operating system:
Linux 32 bit
Linux 64 bit
For the 5AM ECU, you will need the following Reader/Writer software from the GuzziDiag page:
Linux 32 bit:
Linux 64 bit:
For the 15M/15P/15RC ECU you will need these:
Linux 64 bit:
For the MIU G3...

Each is a standalone program that works independently of each other and does not require any extra software.
You will also need the two cables. They are available from various resellers on the net.
EDIT: Lonelec is the best source on the net. They sell a kit that inlcudes both cables and is guaranteed to work
Get it here: CLICKY
!!!! Do not use the drivers that come with the cables. Download the drivers from here:
Mac OS Drivers
1. The OBD2 KKL 16 pin to USB cable with the FTDI chip. This will come with the drivers or they too can be downloaded
2. The Fiat 3 Pin to 16 pin Adapter
To connect to the bike, connect the two 16 pin connectors on the cables together and the 3 pin cable to the diagnostic port. For example on the Griso, it's located under the seat near the back right.
Attach the clips from the 3 pin cable to the battery and plug the USB cable into a USB port on your computer.
A LED on the OBD2 cable will indicate power is connected.
When you are connected to the ECU with one of the programs, you will get a nice display on your instruments.
To read and backup your existing map, open the IAWReader. Your computer may have multiple COM ports, so select the correct one from the drop-down box. it 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.
Then, click on 'read'
A dialog box will open, and here you can select the folder where you want to save the .bin file. You can name it anything you like.
Click 'save'. You will then get:
Turn your keyswitch to 'on'. Do not start the engine. Reader will start downloading. It will take 15 minutes to backup the map.
When it has finished, it will ask you to switch off your keyswitch. Obey.
To write or flash a new map, start the Writer program. You can select your COM port here as well.
Click on the button with the 3 dots, and you will get a dialog box where you can browse to and select the .bin file you wish to flash by clicking 'Load'.
Then, click 'Write'
Same as before, it will ask you to switch your keyswitch on.
It will start the upload. Note the message in the bottom left corner 'uploading'. It takes 3 minutes. It will then change to 'programming' as it writes the file to the ECU.
It will then show a message that it was successful.
Click 'OK' and switch off your keyswitch.
You will then need to reset your TPS. Open the GuzziDiag program.
NOTE: We do not reset the TPS on the V7/V7-II with the MIU G3 ECU
More info on the MIU G3 below.
Click 'File' -> 'Preferences' to configure the software. It only needs to be done once.
The GuzziDiag settings dialog box opens. Here you can select language, COM port and bike type. Click the X to close, when done.
Next we want to connect to the ECU, so click 'File' -> 'Connect'
It will ask you to switch on your keyswitch and click 'OK'
You'll notice there are 8 drop down boxes to select various readouts. Select whatever you wish.
You can see here after uploading the map, my TPS (Throttle) is slightly out. It should read about 4.7
Let's reset it! Click on 'View' -> 'Actors'
You will see the Actors menu:
Next, click on one of the drop-down selection boxes under 'Engine Off'
Select TPS Reset
You'll get the TPS Reset OK dialog. Click OK.
For the MIU G3
In 'Measurements', check the reading for 'Throttle'. For V7 It should be 0.9 - 1.0, for V7-II 1.0 - 1.2.
If the reading is anything outside that range, then (and only then), follow these steps:
1) In the top menu, go to View -> Actors
2) In any of the drop down menus select "Throttle self-learning", then click start.
3) In the top menu, go back to View -> Measurements
4) Check the "Throttle" value. It should now be in the correct range.
To reset the Autolearning parameters (ECU fuel trims), using the drop-down selection box, select 'Reset autolearning parameters', then click 'Start'.
If you want to see some data change, you can start your engine and check out the readouts. Here I simply twisted the throttle (engine was not running).
Once you're done, click 'File' -> 'Disconnect' and you will be prompted to switch off the keyswitch. Switch off the key and click OK.
If you load a new map or do something simple to your stock map like switch of the lambda sensor, you may find you need to adjust the CO trim for a smoother idle or less smelly idle (too much fuel).
To do this with GuzzDiag, get your engine up to temperature (which is 60 deg celsius). Go for a short ride or let it idle with GuzziDiag connected so you can monitor the engine temp.
Once up to 60C, hit the kill switch. Click on 'View' -> 'CO Trim'
You will get the following dialog box. Click 'OK'
You will then be presented with the CO trim menu. Click 'Start'
You will get a dialog box that asks you to start your engine. Click 'Ok' and start 'er up.
With the engine running, click the plus '+' or 'minus '-' button to adjust the CO trim. You can go up to +128 or down to -128.
What value you use will depend on what type of map you have installed and what you are trying to achieve. If you have a map built specifically for the exhaust you have, you should only need to go +/- a small amount. If you smell unburnt fuel, try going to -5. Click 'Finish'. Let it idle for a few seconds. Better or worse? Go up or down as needed. With each change, make sure you click 'Finish'. If you have a rough or lumpy idle, try going positive first. Say, +3 or +5. Better or worse? Go up or down as needed. If you have to go more than 10 in either direction (as a rough guide), you may have the wrong map, or you have a mechanical issue you should address (TB balance or valves), or have forgotten to reset the TPS or autolearning parameters.
When you click 'Start' to make another adjustment, GuzziDiag will ask you start your engine again, but as it is already running, simply click 'OK' and go. Repeat as necessary until idle is smooth and at your required idle RPM. Always make sure you hit the 'Finish' button when you've made a change. Once done, hit the kill switch.
Try not to let the engine get too hot. You can't hurt anything by adjusting the CO trim, so if you feel you haven't quite got it right, let the engine cool off and start again. Of course, you can use a fan to assist with cooling.
