How To Load A Global File, Step By Step

Having trouble loading a global file to your Holley ECU? As Holley tech guru Tom Kise shows you in this helpful, easy-to-follow video, it's not as hard as you probably think. Tom uses a naturally aspirated 454 big-block Chevy street engine with a Holley intake and throttle body for this demonstration, but the basic principles he goes over apply to any application.

In just five minutes, Tom takes you step by step through the process. You'll choose and load a base file, and then enter your information in several key categories – engine type, fuel type, load sensing, wideband 02 sensor, startup settings, fuel system, and fuel injector configuration. These initial parameters will help the ECU establish a base tune as the software compares the existing files loaded in the ECU to the global file you're about to load. In just a few clicks, you'll be on your way!
