Fuel Kits:

Royal Flush EFI Fuel Kits are perfect for those upgrading from a carburetor or stock fuel injection and who already have EFI-compatible ignition components. Each EFI Fuel Kit comes with a standalone EFI system and a complete fuel delivery system. 

Standalone Overview:

Aces EFI’s Royal Flush EFI/CDI is the most powerful TBI system on the market! Integrating our EFI control module and CDI ignition system inside one ECU, this is a revolutionary upgrade and huge leap forward in the world of aftermarket EFI products. By using CDI, you are able to create a much hotter spark in order to burn fuel more efficiently and ensure maximum power, especially in boosted and performance applications.

The Royal Flush EFI/CDI system 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, wideband O2 sensor, ECU, and a 5” touchscreen handheld programmer for easy tuning and monitoring of engine data. 

The system fits any 4150-flange 4-barrel intake manifold and is designed for easy installation and tuning. Installation is straightforward and easy, and the system includes everything you need to get on the road or track quickly. 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 EFI kit 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!

Beyond expectations

Just did a fresh build on my 78 chevy and wanted to upgrade from my last efi system. Super easy install and the wizard was quick work. It ran super smooth at idle and I went from 10mpg to 12ish. I like the timing control feature as well. Keep up the good work yall.
