The Sniper 2 EFI return style drop-in module with PDM and Bluetooth swaps a 4150-flange carburetor for a complete self-tuning fuel injection system, controlled from a smartphone via the Bluetooth module instead of a handheld display. The included Power Distribution Module (PDM) isolates the core EFI and ignition wiring into one location, so only a battery and switched 12-volt source are needed to power the PDM and Sniper EFI.
Key Features:
- Bluetooth module allows tuning and monitoring from an iOS or Android phone instead of a dedicated handheld display
- Optional Power Distribution Module (PDM) included, simplifying wiring — slide stripped wire ends under the positive lock connector and tighten the set screw
- Calibration wizard builds a base map and begins self-tuning from a few engine questions — no laptop required
- All-new throttle body design with redesigned throttle shaft and plate geometry for smoother throttle feel
- Onboard contactless magnetic TPS sensor for accurate throttle position readings
- Included genuine Bosch LSU 4.9 wideband oxygen sensor provides real-time fuel map learning
- Clamp-on oxygen sensor kit with stainless T-bolt clamps and a weldable O2 flange for a leak-free install
- "Hidden Harness" wiring exits from the rear of the throttle body for a clean appearance
- Next-generation mil-spec M8 positive lock connectors for CAN1/CAN2
- Main harness includes plug-and-play HyperSpark distributor support for integrated timing control
- Integrated transmission kickdown provisions for GM TH350/400, 200-4R/700R4, and Ford C4/C6
- Cast-in fuel crossover from the primary to secondary fuel rail
- Next-generation ECU with improved RF noise and interference resistance
- Sniper 2 throttle bodies are individually serialized for improved warranty and service tracking
