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.

ACES Fuel Injection. Black Jack Pro Distributor

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.

ACES Fuel Injection. Low Profile / Black Black Jack Pro Series Ignition Coils

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.

Bluetooth Module

Compatible with Android and iOS* devices and plugs into the CAN connection on the main harness.

Android is available via download here, or in the Google Play Store Fall of 2025.
