The 6.4L Extreme Race Package requires an EGT reading to unlock the hottest tunes and includes a temperature probe and transmitter. The Livewire programmer kit also comes with an Ethernet-to-ODB II cable that connects it to the truck's computer and a mini USB-to-USB 2.0 cable to download custom tunes from www.sctflash.com with your home computer.
Every '08 Super Duty 6.4L comes from the factory with 350 hp and 650 lb-ft of torque, but only about 260 ponies and 490 lb-ft of twist make it to the ground. The F-250 we're building for Airaid is no ordinary Super Duty and needed a lot more power to help motivate 38-inch tires and offset the added weight of a lift kit, bumpers, a bedliner, and wheels. We chose the new SCT Livewire with the Extreme 6.4L Race Package because it provides up to 120 hp and 230 lb-ft of torque more than the stock programming, has an integrated EGT monitoring system, and can be loaded with custom SCT programs in just a few minutes with a home computer or laptop. Here's how we loaded our Livewire with the latest Ford ECU program and the 6.4L Extreme tune in less than 30 minutes after taking it out of the box.
Super-Expandable Memory
One of the SCT Livewire's unique features is the use of a built-in SD flash memory card that can easily expand the memory from a more-than-sufficient 128 MB up to 2 GB or more. Don't pop open your Livewire at home, or the warranty will be void.
The first step in downloading power involved going to the Support section of www.sctflash.com, where we selected the 6.4L Enabled Livewire. | 
Following the instructions shown on the Updater, we depressed the jog wheel on the Livewire and then connected it to the computer with the USB cable. In this mode, the red shift light will illuminate. The first time the Livewire is hooked to your PC, you'll need to use Windows to "safely install hardware" that matches the new drivers with the Livewire. | 
Next, we downloaded the latest Windows drivers (to make sure the Livewire would work with our computer), the newest firmware, and the latest tune for our 6.4L. We then downloaded the Livewire Updater program, which quickly transfers custom SCT programs into the controller. |
