Step 6: Using the QFI DASHBOARD software to connect the PC laptop to the Qfi ECU
As mentioned above, the DASHBOARD software works with WINDOWS XP, WINDOWS VISTA, WINDOWS
7, or WINDOWS 8 operating systems, but not with an Apple laptop.
Perhaps 90-95% of the tuning of the ECU will be done by the Qfi HANDHELD. The data entered into the
ECU with the HANDHELD can be adjusted using the HANDHELD, and will not require the use of the
DASHBOARD program on the laptop.

Insert supplied DVD into laptop’s CD/DVD player

The software will start automatically.

If it does not -- go to My Computer (WINDOWS 7 or 8), double click the CD/DVD Drive icon
o The installation window should pop up on the screen, and the installation procedure will
continue
Open the DASHBOARD software program on the laptop
Once the installation of the DASHBOARD program is complete, you can begin to use the laptop with the
Qfi system. The home screen for the DASHBOARD program is designed to look like a digital dashboard.
It provides a real-time look at the engine’s operation -- important information about the behavior of the
fuel injection system and the environmental data influencing its performance.

Connect the laptop to the Qfi throttle body wiring harness with supplied USB/male 2.5 mm audio-
type jack cable into the female 2.5 mm audio jack-type connector used with the HANDHELD
controller.

Turn the ignition key to “ON” (DO NOT start the vehicle)

Open the QFI DASHBOARD program
o With the key ON and the engine NOT running, you can adjust settings
o From the SETUP TAB, select the MAIN SETUP from the Drop-Down menu
 This will show all of the settings you have seen and made on the HANDHELD device.
 A unique feature is the ability to HOVER the mouse icon over the topic description, or the
cell description, and see additional information about the definition and function

Start the engine
o With the engine RUNNING, you can observe the engine’s parameters in real time by selecting
the VIEW TAB at the top of the page, and select ECU Real-Time
o You will see some numbers remaining constant, others will change
o These numbers will change as engine rpm increase/decrease, as engine loads vary, etc.
Adjusting the profile to the vehicle
The most common use of the DASHBOARD program will be in the case of a CUSTOM GRIND CAM.
Because the cam specs may be significantly different than stock, performance or race type cam
options in the Cam Type window on the HANDHELD.
