Internal ECU
No room on the firewall? No problem. The Fusion's internal ECU makes for a much cleaner look under the hood. Read about our durability testing and R&D behind it here.
Minimal Wires
Designed for simplicity, the wire harness has only a few wires to connect:
- Main power
- Ground
- Key on power wire
- Fuel pump wire
- Distributor wire
Better Ingredients. Better Performance.
Industrial-grade components? Never heard of her. Only automotive-grade components here. Aces only uses OEM-level components, which means better reliability and capbility.
Disco under the hood.
We spent the last 5 years making sure our onboard ECU would hold up under the same conditions that plagued other companies. What better way to celebrate than with a mini rave?
If the shoe (throttle body) fits.
The Killshot Fusion uses the common 4150 style flange found on many classic engine manifolds, making it very versatile when it comes to compatibility. As long as the TBI unit fits, is within the appropriate HP range, and your engine uses a classic distributor, it's a match made in heaven...or the garage.
Master Kit Feature
(Fuel) Pump Up the Jam
Each Master Kit will come with a fuel system of your choosing. You can scroll down to read more about the available options below.
255 In-line Fuel System
A frame-mounted in-line pump with all of the necessary fittings and hose.
Command Center 2
A surge tank system that allows you to keep your mechanical pump in place. A better option for classic trucks or other vehicles where the tank is hard to access.
Tight-fit In Tank Pump Module
An in-tank fuel pump module available with or without PTFE hose.
Requires a return line to the tank.
Tank Conversion Fuel Pump Module
An in-tank fuel pump module with an internal regulator. Ideal for fuel cells.
Does not require a return line to the tank.
Master Kit Feature
Distributors for Days
Each Master Kit will also come with a Distributor of your choosing and an ignition coil to allow you to run timing control.
Magnetic Pickup Distributor
With over 15 options to choose from, our line of Black Jack Pro Magnetic Pickup Distributors lets you run your EFI with mechanical advance or lock it out to allow the ECU to control timing.
Ignition Coil
The high-output magnet in the Black Jack Pro Ignition Coil creates 50,000 volts, or about 70% more spark energy over most stock-style applications, giving you a significantly hotter and larger spark for more complete combustion. This helps create more horsepower and torque, providing smooth acceleration throughout the entire RPM band.
How do I set up and program my system?
Interface Options
Our EFI systems are self-learning for most stock-to-mild engine builds. You’ll use one of the included interface modules (depending on the option selected at purchase) to complete the initial setup and make adjustments on the fly. The startup wizard will prompt you with 6–12 setup questions, after which the self-learn feature takes over.
Additional fine-tuning may be required later, depending on your specific build.

Most common questions
Quick answers to our most common queries for this product.
The Kits maestros de fusión Killshot are designed to work with any classic 4, 6, or 8 cylinder engine that is under 650 hp, uses a 4150 style flange, and has a fuel system rated for EFI (43 PSI).
The self learn will work for most stock-mild builds, while some mild and more advanced builds may require manual tuning.
The Kits maestros de fusión Killshot are designed to work with most stock or aftermarket ignition components. They will work with most tachometers and are compatible with Dakota Digital dashes using their Aces BIM Module (BIM-EFI-1).
Self-tuning is a common term used among aftermarket EFI companies, but we prefer the term "self-learning" as that is more accurate, even for our competitors who advertise "self-tuning."
Our systems are designed to self-learn the fuel MAPs and work best for stock-mild builds. Some mild builds and anything beyond that would require manual tuning, of which the system is fully capable. Additional features like nitrous and boost are also considered beyond stock and require manual adjustments to enable and configure these kinds of features.
Yes! You can make many changes using the Bluetooth or handheld interface, and we also offer a free PC app for more advanced tuning.
The Kits maestros de fusión Killshot can work with standard stock or aftermarket ignition components, but if you want to run timing control, it will need either a magnetic pickup distributor that has been locked out or a Hall Effect distributor. You will also need to make sure that your fuel delivery system can support 43-58 PSI. Whether or not you need a return line will depend on your fuel delivery system and if the regulator is inside or outside the tank. Whether or not you need to replace your tank will depend on which fuel delivery system you choose. We offer complete Master Kits for each EFI system that come with new ignition components and a fuel delivery system. You can visit the Killshot Fusion Master Kits page here.
Yes to both! The Kits maestros de fusión Killshot are compatible with both blow-through, draw-through, and nitrous applications and are also compatible with E85 Fuels. The Kits maestros de fusión Killshot' MAP sensor can be scaled for up to 26 lbs of boost and can be set to retard timing.
Note that for boost, the system is compatible, but cannot control the boost. You will need to use a separate controller for things such as wastegate control or solenoid activation. Use of these features will require manual tuning.
