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.\u003c\/em\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch2\u003eEngineered Precision. Integrated Simplicity. Real-World Durability.\u003c\/h2\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003cp\u003eIn 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.\u003c\/p\u003e\n\u003ch2\u003eBuilt from the Core Up – Smart, Strong, Stable\u003c\/h2\u003e\n\u003cp\u003eAt 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.\u003c\/p\u003e\n\u003cp\u003eFusion 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.\u003c\/p\u003e\n\u003ch2\u003eRe-Engineered for the Harshest Realities\u003c\/h2\u003e\n\u003cp\u003eMany EFI systems fail because they ignore the reality of engine bay conditions, heat, vibration, electromagnetic interference (EMI), and moisture.
