Description
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!

8 Injectors
Sequential EFI System
True sequential EFI with individual cylinder trim which offers more precise control compared to batch-fire/bank-to-bank systems.
Computing Power
A robust ECU that utilizes our OEM standard 32-bit architecture. This allows the system to manage input/output signals, voltage, and RPM faster and more consistently than our competitors.
Plug 'n' Play
Not a tuning wiz? You don't need to be since we provide a wizard for you. Our self-learning* functionality means you only have to answer a few basic questions in the startup wizard and then the ECU takes care of the rest. After about 30-60 mins of idling and drive time, the system will build it's own tune so you don't have to. Click here to learn more about our handhelds and dashes and see all of their features.
*Self-learn works best for stock-mild applications. For more aggressive applications and even some stock-mild applications, we offer free tuning software on our website.
It takes two.
The Joker EFI/CDI system utilizes two WBO2 sensors to read each bank of your V8 engine. Dual wide-band sensors allow precise calibration of each cylinder bank, optimizing performance and allowing more thorough tuning of your engine without any compromises.

Marine Applications?
Is it marine or coast guard approved/certified? No. None of our products are.
Do we recommend it? No, since water and engines don't generally mix and warrantying items in these conditions becomes tricky. These are also modified applications that are not 100% what the systems were designed for.
Will it work? Yes, with some modifications for the WBO2 sensor.
Is it E85 compatible?
Yes, you just would need to change some settings first in order for it to work.
Please note that damages to the system caused by the use of E85 or other racing fuels are not covered by our warranty policy. This is because E85 is known to corrode certain types of material over time and our systems were not designed for long-term E85 use.
Will it work with aftermarket or stock gauges?
The system is not generally setup to work with stock gauges which is why we provide the handheld to display all the readings. Aftermarket tachometers will work with the system, and we are working to provide support for other popular aftermarket gauges soon!
Are the leads all pre-terminated?
Except for a few loose wires, almost all wire leads are pre-terminated.
What style of injectors are compatible?
The Jackpot uses EV6 pico style injector plugs, but you can always use an adaptor if you have different injectors.
What kind of tech support do you offer?
Aces offers general support on product setup, installation, troubleshooting, and basic diagnostic help.
While most stock-mild applications do not require tuning, some applications (usually more aggressive cams or boosted applications) may require additonal tuning beyond what the self-learn is capable of. Aces does not offer custom tuning though we can recommend Authorized Aces Tuners who may charge a fee for their services. Read more about our support services and what to expect here.
