Product Info
Overview
The Future of Throttle Body EFI is Here
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.

Customer Reviews
The Killshot Fusion was very easy to install. The slimmer throttle body design allows for a wide range of air cleaner configurations, making it versatile for different setups.
Once installed and the wiring was tucked away, it blended seamlessly into the engine bay—maintaining a classic look while delivering the reliability and tunability Aces EFI is known for.
On a stock engine, I had to make little to no adjustments. I simply bolted it on, ran the Start Wizard, and was on the road the next day.
This unit was super easy to install and fired right up. I only needed minimal adjustments to the IAC and a little tuning to get it to idle and run smoothly. Although the vehicle has suspension issues that need to be addressed, it ran great before I had to park it. Even after sitting for a week or two at a time, it still fires right up without a problem. Very satisfied so far!
We have been testing the new ACES KS Fusion for a few months now and have been impressed with its ease of installation, product packaging, and out-of-the-box success. The KS Fusion uses a 4150-style flange, side-mounted integrated ECU, and a simplified harness to make any carb guy say “this is too easy.” The system came with the older 5” screen and mount, harnesses, wideband O2, and CTS sensor. Installation took about 15 minutes to complete from removal of the Aces KS2 to installation of the KS Fusion and wizard setup. The wizard tune fired up using the ACES Gambler distributor, I let it get to operating temperature, adjusted the IAC, and went on a short drive to evaluate the system functionality. I am really impressed with the ease of use, less wires, and plug and play approach. ACES EFI is truly for the people and passionate about EFI technology, 5 out 5 stars from Justin at Proto-Tech LLC. 5/5
Super easy installation, everything just bolted on and plugged in with the exception of the battery + and -. With my setup, I was able to set the timing and it fired up with very little adjustments. My setup is pretty mild but I had more time messing with the Killshot 1 settings than I spent doing the entire Fusion install beginning to end. The integrated ecu is a nice touch and makes the under hood appearance much cleaner. Time will tell how it holds up, but so far so good! I will be removing this from my 1984 Cutlass and transferring it over to my wife's 1985 F150 for more testing from a non-car person's standpoint here later this year.
We like the smaller size of the unit, it has a good look to it.
The installation is simpler without the external ECU.
We haven't had any runtime on the unit yet due to an electrical issue, and a transmission swap with the car, but that is coming soon, and I will provide that feedback soon. 5/5
