4- Sending a calibration file to the VFI module.
a- From the File menu of ProTune II, select "Send all data to ECM…" or click on the motorcycle icon in the upper-left corner of the screen.
b- A window will open showing a list of calibration folders for the different S&S ECMs. From the list of folders select the folder for “USB Port
Magneti Marelli® Style ECM” to view the list of calibrations available for this ECM.
c- Select the calibration for the vehicle the VFI module is installed.
i. Calibrations are named based on the calibration part number, year group of bike, chassis, type of ECM, engine, displacement,
compression ratio, cam, exhaust system, and other notes such as if it is setup for closed loop. Calibration notes can also be viewed
in the “description” box located on the left side of the calibration selection window.
ii. Locate a calibration that is correct for your year group with the closest displacement and camshaft to what you are running.
iii. If the calibration selected is noted as closed loop, and the vehicle does not have the S&S Closed Loop Sensor kit installed, the closed
loop control will need to be disabled per step 5.
d- Once a calibration is selected click Open to start the calibration download process. Do not switch off power to the ECM during this time.
e- After the calibration has loaded a message will appear advising you to cycle power on the ECM (VFI module) for at least 15 seconds.
Select OK on the message and turn the key off on the motorcycle for at least 15 seconds.
5- Closed Loop Control Settings.
a- If the calibration installed was noted closed loop and the vehicle does not have the closed loop kit installed the closed loop control will
need to be deactivated. Failure to deactivate closed loop control on a motorcycle without a Closed Loop Oxygen Sensor kit will result
in a trouble code being set and the check engine light illuminated.
b- To deactivate closed loop control, with ProTune II connected to the ECM select “Closed-Loop Control Settings” from the view menu.
c- A new window will open asking to select an ECM or file to edit.
d- By default the ECM: 55-5120A will be selected. Hit OK to continue.
e- In the new window that opens select "No Closed-Loop or Adaptive" from the drop down menu and hit Save.
6- Viewing Calibration Comment Field.
a- The comment field for each calibration contains the calibration part number and notes on the application and software code for the
calibration. To view the comment field select “Comment Field…” from the View menu in ProTune II.
b- A new window will open to select the source for the comment field. When connected to a powered ECM the ECM will be shown first on
the list by default. Select OK to view the comment field of the calibration in the ECM.
c- A new window will open showing the notes for the calibration starting with the part number of the calibration. Additional notes can be
added if desired and saved to the calibration by hitting OK on the comment field window.
The VFI module calibration is now complete. The VFI module uses an aluminum plug cover with an O-ring to protect the module’s USB port from the
elements. Install the O-ring and port cover on the module using the two screws provided.
For additional calibrations, troubleshooting, and tuning information see the VFI S&S USB Magneti Marelli® Style VFI Module and ProTune II Software
installation instructions provided with the module.
