3.2 Basic Computer Operation
Once the software is installed, a Holley EFI icon should appear on the main computer screen. When you
double-click on this icon, the software should start. There is a USB communications cable that needs to
be hooked up to the ECU (it connects directly into the ECU USB port) for you to program and view data
in the ECU. This cable needs to be plugged into any USB port on the laptop computer.
3.3 Software Operation and Navigation
The Holley HP and Dominator EFI software offers many unique features that set it apart from other
products. Some of these features are designed for experienced tuners and shops that tune many
applications and desire to create a database of base calibrations.
3.3.1 Basic Operation
File Structure Overview – One of the main differences of this EFI system is that the “Calibration” or
“Map” is not a typical single file, but is actually stored within a standard Windows “Folder”. This folder
is called a Global Folder. The term Global Folder (abbreviated GF) will be used throughout this manual.
It is synonymous with the typical terms such as “Map”, “Base Map” and others. This folder contains
multiple files that make up the “Base Calibration”. These individual files are called Individual
Configuration Files (abbreviated ICF).
GLOBAL FOLDER (GF) – The “base calibration” or “map”. This is a standard Windows “folder”.
INDIVIDUAL CONFIGURATION FILES (ICF) – Individual files contained with the Global Folder that make
up the “base calibration”.
This method offers a lot of advantages. When a new base calibration is created, it allows the user to
select from a library of individual files for each portion, to create a base calibration that is unique and
specific to that application. When a new calibration is completed, a file can be “disassembled” and
imported back into the library.
