When the link opens select “Run” twice, “Next” four times and “Install” once. The program will then self install, creating the correct file hierarchy, which is C:\Program Files\BigStuff\BigComm

Note: If your GEN3 ECU has a build date before January 2008 you should update the firmware before installing this software. The build date is located on the back side of the ECU. The cost for firmware updates is $100 USD, plus S&H. Please call BigStuff3 for more information.

By the “90s, hoards of enthusiasts were jumping on the EFI bandwagon and singing the praises of driveability, gas mileage, and (sometimes) horsepower improvements. But in the realm of serious power, limitations in factory electronics capped ultimate potential. EFI didn’t like big cams, refused to rev beyond the factory air/fuel maps, and didn’t get along with injectors big enough to make real horsepower. Then in the mid”80s, computer-whiz John Meaney created a standalone engine management system that controlled fuel and spark independently from the factory computer. Dubbed Digital Fuel Injection (DFI), Meaney’s device provided almost limitless tuning potential based on a few simple parameters. The DOS based software was easy to navigate and affordable real -time fuel/spark changes. Engine combos once deemed to radical for the street could be tamed to chug comfortably on the freeway and idle smoothly without sacrificing any power. A true testament to DFI’s potential is its impact on import drag racing, where big block-level air and fuel flow was crammed into four tiny cylinders and effectively managed with just four injectors. Meaney began marketing DFI through ACCEL in 1991, later developed a new standalone system for F.A.S.T., and is now offering his latest and greatest BigStuff3 system on his own. Corporate buyouts aside, DFI helped EFI reach its true performance potential and precipitated a new market of powerful standalone controllers for racers and hot rodders to choose from
