Show original supplier description
The Aces Fuel Injection Killshot 2 Pro EFI System offers a comprehensive upgrade from carburetion to electronic fuel injection for classic engines. Designed for engines up to 650 HP (NA) or 550 HP (boosted), it utilizes a 1,000 CFM throttle body with a 4150 style flange and a 64-bit RISC-V processor. This system includes a self-learning ECU, full harness, sensors, and a choice of a handheld or Bluetooth module for interface and tuning. The Killshot 2 Pro is compatible with most stock or aftermarket ignition components and tachometers. For timing control, it requires a locked-out magnetic pickup distributor or a Hall Effect distributor. The system supports a fuel pressure range of 43-58 PSI and is E85 compatible with proper tuning. It also features advanced capabilities such as boost control readiness (requires separate controller and manual tuning), wet nitrous control, and a built-in idle air control motor. Installation considerations include the need for a fuel delivery system capable of 43-58 PSI. Depending on the chosen fuel delivery system, a return line or tank modification may be necessary. Aces Fuel offers complete Master Kits that include new ignition components and a fuel delivery system to simplify the conversion.
