Killshot 2 Pro EFI System

The Aces Fuel Injection Killshot 2 Pro EFI System is a comprehensive throttle body injection (TBI) upgrade for classic 4, 6, or 8-cylinder engines. Designed for optimal airflow and power delivery, it features a 1,000 CFM, 4150-style flange throttle body constructed from cast aluminum and available in black, polished, or gold finishes. This system supports naturally aspirated engines up to 650 HP and boosted applications up to 550 HP, with boost compatibility up to 26 lbs. This kit includes the Killshot 2 Pro ECU, throttle body, your choice of a handheld or Bluetooth module, a full wiring harness, sensors (including MAP, fuel pressure, and coolant temperature), and accessories like a Power Distribution Module (PDM). It offers advanced features such as self-learning capabilities, datalogging, ignition timing control, EGT support, fan control, and progressive linkage. The system is also E85 compatible, though it requires proper fuel tuning out of the box. For optimal performance and ignition control, a magnetic pickup distributor that has been locked out or a Hall Effect distributor is recommended. The system requires a fuel system capable of maintaining 43-58 PSI. While the system can handle boost, it does not control it directly, requiring a separate controller for wastegate or solenoid activation. Use of boost and E85 features necessitates manual tuning. The system is compatible with most stock or aftermarket ignition components, and can interface with Dakota Digital dashes via an optional BIM module.
