The Joker™ EFI

ACES Fuel Injection provides next-level performance for your Small-Block Chevy V8 engine with it’s the Joker™ Sequential Multi-Port Injection EFI Kit with integrated CDI ignition. This kit features an aluminum intake manifold (available in two finishes, black and raw aluminum), throttle body, the fuel rails, 36 lb./hr. fuel injectors (8), and all the necessary sensors to get your SBC up and running. ACES Fuel Injection designed a fully Sequential Multiport Fuel Injection to provide the best fuel distribution for your traditional SBC engine. Sequential Multi-Point Fuel Injection meters fuel more precisely than TBI-style systems, giving you more precise control over air-fuel ratio, better cold start, and improved fuel distribution through the entire rpm band. This results in improved fuel economy, increased power, and enhances throttle response at any RPM!

The Joker^™ ECU is built on ACES’ 32-bit Power Architecture®. This technology allows the ECU to manage input and output signals and voltage (fuel injectors, ignitions coils, sensors and triggers), as well as RPM signal faster and more consistently than any other EFI system available. The Joker™ EFI kit includes a CNC-machined cast aluminum throttle body, high-quality cast aluminum, single-plane SBC intake manifold, fuel rails, 36 lb/hr fuel injectors, sealed connectors, Bosch 4.9 wideband O2 Sensors, and OE-quality sensors. Combined, this gives you the most advanced multi-port EFI system available.

ACES EFI’s The Joker™ EFI kit include a 5" LCD high-resolution, full-color, touchscreen handheld controller. The ACES EFI tuning software includes multiple base calibrations to choose from either naturally aspirated or boosted applications. The calibration wizard allows you to answer a few simple questions about your specific combination, giving you the perfect start-up tune. Once the system is up and running, the Self-Tuning functionality monitors data and makes real-time changes to the calibration taking all the guesswork out of the tuning process. The more you drive, the better the tune! If you have a higher-horsepower combination or require more advance tuning features, ACES EFI tuning software provides an easy-to-use software suite that allows full access for advanced users (laptop required).

Whether you are building a budget beater or a boosted racing car, ACES EFI’s The Joker™ EFI kit has the technology and advanced features to you need, in an easy-to-install, easy-to-tune package so you can take your ride to the next level!
