Killshot 2 Pro EFI System

The Ace's Killshot 2 Pro EFI System offers a significant upgrade from carburetors to modern throttle body injection for classic engines. It is engineered for universal fitment on 4, 6, or 8-cylinder engines producing up to 650 HP naturally aspirated or 550 HP with forced induction. The system utilizes a 4150-style flange and requires a fuel system capable of delivering 43-58 PSI. This comprehensive system includes a throttle body with four 100 lb/hr fuel injectors, an ECU, a full harness, sensors, and a handheld or Bluetooth module for calibration and monitoring. It supports advanced features such as ignition timing control, datalogging, fan control, and EGT sensing. The throttle body itself has a 1,000 CFM rating and a low-profile design for improved air cleaner fitment. The Killshot 2 Pro EFI System is designed for self-learning capabilities, making it ideal for stock to mild engine builds. However, more aggressive builds or the use of features like boost control and E85 fuel will require manual tuning. The system is boost compatible up to 26 lbs and E85 compatible with proper fuel tuning. For timing control, a locked-out distributor or Hall Effect distributor is necessary.
