Killshot 2 Pro EFI System

The ACES Fuel Injection Killshot 2 Pro EFI System represents an upgrade from traditional carburetors to electronic fuel injection. This TBI system is engineered for classic 4, 6, or 8-cylinder engines producing up to 650 horsepower naturally aspirated or 550 horsepower with boost. It features a 1,000 CFM throttle body with a 5-1/8" air cleaner diameter and a 4150 style flange, ensuring broad compatibility with common air cleaners and intake manifolds. The Killshot 2 Pro boasts advanced features for improved engine management, including self-learning fuel mapping, integrated TPS, MAP, and IAT sensors, and support for advanced tuning software. It is compatible with various ignition components, including MAG, Hall-Effect, and CDI distributors, and can be set to retard timing for boost or nitrous applications. The system also includes a built-in fuel pressure sensor, progressive linkage, and supports fuel level input and EGT monitoring. For enhanced drivability and performance, it offers fan control and ported vacuum. To transition from carburetion to EFI, the Killshot 2 Pro requires a fuel system capable of supporting 43-58 PSI. If ignition timing control is desired, a locked-out distributor or a Hall Effect distributor is necessary. ACES offers complete Master Kits that include new ignition components and a fuel delivery system for a comprehensive conversion. The system supports firmware updates and features a CAN-BUS for expanded connectivity.
