Aces' Killshot EFI system is one of the most advanced throttle body injection (TBI) systems on the market. The Killshot utilizes four 100 lb/hr fuel injectors, giving the system the capability of supporting up to 650 horsepower. The system includes the throttle body (with integrated fuel injectors, TPS sensor, MAP sensor, IAT sensor, and stepper motors), wiring harness, WBO2 sensor, ECU, and a 5” touchscreen handheld programmer for easy tuning and monitoring of engine data.
The Killshot system fits most 4150-flange 4-barrel intake manifolds and is designed for easy installation and tuning. For stock to mild applications, the calibration wizard and self-learning features mean advanced tuning knowledge or experience is not required. But for more aggressive or performance oriented applications, Aces offers a full tuning software suite and USB data cable for advanced manual tuning.
Aces designed its throttle body systems with the ECU separate from the throttle body. This alleviates any issues with possible damage to the ECU from unwanted engine heat or vibration. This is a common problem with other “all-in-one” style systems on the market.
Whether you are building a budget beater or a boosted racing car, Aces EFI’s Killshot system has the technology and advanced features you need, in an easy-to-install, easy-to-tune package so you can take your ride to the next level!
For timing control, the Killshot requires a magnetic pickup or hall effects distributor and separate ignition coil. We recommend our Black Jack Pro series distributor and ignition coil for a plug & play experience.
