Killshot Fusion Top End Kits
Killshot Fusion Top End Kits
These kits include a Standalone Killshot Fusion EFI system + a Magnetic Pickup Distributor (and coil) of your choosing. The Killshot Fusion Top End Kits are perfect if you already have a high-pressure fuel system (43+ PSI) and want to run timing control.
Engineered Precision. Integrated Simplicity. Real-World Durability.
The Killshot Fusion is the next evolution in throttle body EFI systems. Building upon the success of the original Killshot, the Fusion takes everything users loved, robust hardware, accurate fuel delivery, and ease of tuning, and reimagines it with a fully integrated design that eliminates clutter, simplifies installation, and dramatically boosts reliability.
In a world where many EFI manufacturers rushed to integrate ECUs onto the throttle body and paid the price in failures, Aces EFI took a different path: more time, more engineering, and more testing. The result is Killshot Fusion, a true all-in-one TBI system that thrives where others fail.
Built from the Core Up – Smart, Strong, Stable
At the heart of the Killshot Fusion is a high-performance 32-bit automotive-grade microcontroller based on the PowerPC e200z0h core. This platform enables lightning-fast input/output processing, superior sensor management, and high-resolution fuel and spark control. Combined with Aces’ proprietary software and a proven B50 control chip, it delivers performance you can trust in any application, from street cruising to competitive racing.
Fusion also includes advanced ECC memory protection, a Memory Protection Unit (MPU), and a 4-layer PCB with a dedicated power plane. This design significantly reduces voltage fluctuations and impedance, ensuring system stability and durability, even in extreme environments.
Re-Engineered for the Harshest Realities
Many EFI systems fail because they ignore the reality of engine bay conditions, heat, vibration, electromagnetic interference (EMI), and moisture. The Killshot Fusion addresses each of these with purpose-built solutions:
- Potting-Protected ECU: The Fusion’s internal PCB is encapsulated in specialized potting material that insulates electronics from heat and shields against vibration, impact, and contamination.
- Dual Ignition MOSFET Drivers: Enhance ignition reliability by providing strong and stable spark energy under all conditions.
- Multi-Stage Filtering & Active Digital Shielding: Prevents noise interference from ignition systems and surrounding electronics, preserving signal clarity.
- EMI & Environmental Testing: The Fusion has passed extensive vibration, salt spray, and EMI validations, tests where competitor systems often fail. This isn’t just rugged, it’s refined, lab-proven durability.
Integrated Design, Maximum Simplicity
With the ECU and harness connectors integrated directly onto the throttle body, installation is faster, cleaner, and more reliable. There’s no need to mount an external ECU, route long harnesses, or deal with complex wiring. Just bolt it on, plug it in, and fire it up.
- Symmetrical Harness Layout: Connectors on both sides of the unit allow for clean cable routing no matter your engine bay configuration.
- Reduced Points of Failure: Fewer connectors and wires mean fewer potential problems down the road.
- No External ECU: Fewer boxes, fewer mounting brackets, and a dramatically cleaner engine bay appearance.
Advanced Software with Self-Learning Intelligence
Killshot Fusion’s control software doesn’t just respond to your engine, it learns it. Every second the system is running, it’s analyzing, adapting, and refining its control strategy for your unique build.
- Predictive Ignition Timing: Software anticipates and adjusts spark timing for optimal combustion under dynamic conditions to better meet timing targets.
- Accurate Injector Phasing: Improved synchronization between injectors enhances performance and fuel economy.
- Rapid Self-Learning: The ECU quickly adapts to your engine's fueling needs—no laptop required during setup.
- Anti-Interference Control: Predictive shielding algorithms mitigate signal disruptions before they occur.
Whether you’re adjusting idle quality or optimizing for boost, Fusion’s software is tuned to perform.

Why Killshot Fusion? Why Aces EFI?
While others shipped flawed designs to meet a trend, Aces EFI held the line—refining, validating, and testing until we had a product worthy of our name. The Killshot Fusion is the culmination of five years of ECU and TBI development, engineered specifically for real-world performance and long-term reliability.
From weekend warriors to serious tuners, Killshot Fusion offers the confidence of clean installation, the control of pro-level tuning, and the backbone of proven engineering.
If you’re ready for a throttle body EFI system that does more than look the part, this is it.
