Custom-Tunable EFI to Fill the Gap Between EZ-EFI & XFI 2.0
Designed for muscle car, late model street and sportsman drag racing engines, along with boosted and individual runner throttle body applications, the FAST™ XFI Sportsman™ Engine Control System is a bank-to-bank, fully software-tunable EFI setup. It requires a laptop for tuning and uses proven FAST™ C-Com® software, which comes packaged along with the necessary USB connectivity cable. The system offers both load-indexed Speed Density or Alpha-N fuel strategies; most users will use Speed Density but the Alpha-N option is specifically added to serve Sportsman drag racers looking for absolute consistency.
