Product Details

The Sniper EFI 550-850 is a self-tuning electronic fuel injection system designed as a bolt-on replacement for 2300 flange carburetors. This complete EFI conversion features an integrated ECU mounted directly to the throttle body, eliminating extra mounting requirements and reducing RF interference.

Key Features:

  • Self-tuning ECU with intuitive setup calibration wizard for automatic base tune creation
  • Dual 100 lb./hr. fuel injectors provide ample fuel delivery for performance applications
  • 3.5-inch LCD touchscreen handheld controller for real-time data logging, tuning, and gauge displays with SD card support
  • Bosch LSU 4.9 wideband O2 sensor enables real-time fuel map learning with included stainless steel flange and T-bolt clamps (no welding required)
  • Internal fuel pressure regulator preset to 58.5 PSI eliminates need for external regulator plumbing
  • Compatible with many common 5 1/8-inch OEM and aftermarket air cleaner assemblies
  • Equipped with transmission kickdown provisions for C4/C6 Ford, TH350, TH400, and 700R4 transmissions
  • Simplified installation requires only four wiring connections: battery positive, battery negative, switched ignition, and RPM signal

Certified to ISO 8846, SAE J1171, and United States Coast Guard requirements for ignition protection and fire resistance, making it suitable for marine applications. The black finish provides a clean, professional appearance in any engine bay.
