BIM Expansion Holley Sniper 2 EFI Interface

The Dakota Digital BIM Expansion Holley Sniper 2 EFI Interface is a dedicated gauge interface module designed to bridge modern fuel injection systems with analog instrumentation. This compact expansion unit monitors critical engine parameters—tachometer signal, coolant temperature, air/fuel ratio, and manifold absolute pressure—directly from Holley Sniper 2 EFI controllers, translating digital data into precise analog readouts for traditional gauge clusters.

The BIM-01-2-HSN2 interface module weighs just 0.49 lbs and measures 5.45 x 2.35 x 5.75 inches, allowing flexible mounting in engine bays with tight packaging constraints. Its plastic construction keeps weight minimal without sacrificing durability. The black finish integrates seamlessly with modern engine bay aesthetics. Four dedicated sensor channels—one each for tach, temperature, AFR, and MAP—provide real-time diagnostic capability, eliminating the need for aftermarket digital displays when operating legacy instrumentation. This enables technicians and builders to maintain factory or period-correct gauge presentations while leveraging contemporary fuel injection management.

The Holley Sniper 2 EFI interface is essential for custom builds, engine swaps, and restorations where OEM or vintage gauges are retained but EFI control is required. Street rodders, classic car enthusiasts, and engine builders commonly deploy this type of interface to preserve original dash configurations while gaining the fuel economy, cold-start reliability, and tuning precision of modern fuel injection. Technicians appreciate its straightforward installation and direct Holley Sniper 2 compatibility, eliminating complex wiring logic or secondary adapter layers.
