Kits Maestros Killshot Fusion

Estos kits incluyen un sistema EFI Killshot Fusion autónomo + un distribuidor de captación magnética (y bobina) de su elección + un sistema de suministro de combustible de su elección. Los Kits Maestros Killshot Fusion incluyen todo lo que necesita para pasar de un carburador a un EFI.

Precisión de Ingeniería. Simplicidad Integrada. Durabilidad en el Mundo Real.

El Killshot Fusion es la próxima evolución en sistemas EFI de cuerpo de aceleración. Basándose en el éxito del Killshot original, el Fusion toma todo lo que los usuarios amaban (hardware robusto, suministro preciso de combustible y facilidad de ajuste) y lo reinventa con un diseño completamente integrado que elimina el desorden, simplifica la instalación y aumenta drásticamente la confiabilidad.

En un mundo donde muchos fabricantes de EFI se apresuraron a integrar ECU en el cuerpo del acelerador y pagaron el precio de las fallas, Aces EFI tomó un camino diferente: más tiempo, más ingeniería y más pruebas. El resultado es Killshot Fusion, un verdadero sistema TBI todo en uno que prospera donde otros fallan.

Construido desde la Base: Inteligente, Fuerte, Estable

En el corazón del Killshot Fusion se encuentra un microcontrolador de alto rendimiento de 32 bits para automóviles basado en el núcleo PowerPC e200z0h. Esta plataforma permite un procesamiento de entrada/salida ultrarrápido, una gestión superior de los sensores y un control de combustible y chispa de alta resolución. Combinado con el software propietario de Aces y un chip de control B50 probado, ofrece un rendimiento en el que puede confiar en cualquier aplicación, desde el crucero urbano hasta las carreras de competición.

Fusion también incluye protección avanzada de memoria ECC, una Unidad de Protección de Memoria (MPU) y una PCB de 4 capas con un plano de energía dedicado. Este diseño reduce significativamente las fluctuaciones de voltaje y la impedancia, lo que garantiza la estabilidad y durabilidad del sistema, incluso en entornos extremos.

Rediseñado para las Realidades Más Duras

Muchos sistemas EFI fallan porque ignoran la realidad de las condiciones del compartimento del motor: calor, vibración, interferencia electromagnética (EMI) y humedad. El Killshot Fusion aborda cada uno de estos con soluciones diseñadas específicamente:

  • ECU protegida con encapsulado: La PCB interna del Fusion está encapsulada en un material de encapsulado especializado que aísla los componentes electrónicos del calor y protege contra la vibración, el impacto y la contaminación.
  • Controladores MOSFET de encendido dual: Mejoran la fiabilidad del encendido al proporcionar una energía de chispa fuerte y estable en todas las condiciones.
  • Filtrado multietapa y blindaje digital activo: Evita la interferencia de ruido de los sistemas de encendido y la electrónica circundante, preservando la claridad de la señal.
  • Pruebas de EMI y ambientales: El Fusion ha pasado extensas validaciones de vibración, niebla salina y EMI, pruebas en las que los sistemas de la competencia a menudo fallan. Esto no es solo robusto, es una durabilidad refinada y probada en laboratorio.

Diseño Integrado, Máxima Simplicidad

Con la ECU y los conectores del mazo de cables integrados directamente en el cuerpo del acelerador, la instalación es más rápida, limpia y fiable. No es necesario montar una ECU externa, tender mazos de cables largos ni lidiar con un cableado complejo. Simplemente atorníllelo, enchúfelo y enciéndalo.

  • Diseño de arnés simétrico: Los conectores a ambos lados de la unidad permiten un enrutamiento de cables limpio, independientemente de la configuración del compartimiento del motor.
  • Puntos de falla reducidos: Menos conectores y cables significan menos problemas potenciales en el futuro.
  • Sin ECU externa: Menos cajas, menos soportes de montaje y una apariencia del compartimiento del motor dramáticamente más limpia.

Software Avanzado con Inteligencia de Autoaprendizaje

El software de control de Killshot Fusion no solo responde a su motor, sino que lo aprende. Cada segundo que el sistema está funcionando, analiza, adapta y refina su estrategia de control para su configuración única.

  • Sincronización de encendido predictiva: El software anticipa y ajusta la sincronización de chispa para una combustión óptima en condiciones dinámicas para cumplir mejor con los objetivos de sincronización.
  • Fase precisa del inyector: La sincronización mejorada entre los inyectores mejora el rendimiento y la economía de combustible.
  • Autoaprendizaje rápido: La ECU se adapta rápidamente a las necesidades de combustible de su motor, sin necesidad de una computadora portátil durante la configuración.
  • Control antiinterferencias: Los algoritmos de blindaje predictivo mitigan las interrupciones de la señal antes de que ocurran.

Ya sea que esté ajustando la calidad de la marcha en vacío u optimizando para el aumento de presión, el software de Fusion está diseñado para funcionar.

Hardware de Rendimiento: Cargado y Listo

  • (4) Inyectores de 100 lb/h: admite hasta 650 caballos de fuerza
  • Controlador de bobina integrado: para control de encendido directo
  • Retardo de paso: control de tiempo incorporado para aplicaciones de óxido nitroso

  • Sensores incorporados: MAP, TPS, IAT y O2 de banda ancha 4.9 incluidos
  • Control de ventilador dual: optimiza la estrategia de enfriamiento
  • Pantalla táctil a color de 5 pulgadas: incluye velocímetro GPS, monitoreo y asistente de configuración intuitivo
  • Software de ajuste avanzado: ajuste gratuito basado en computadora portátil con tablas de nivel profesional y datos en vivo
  • Totalmente compatible: funciona con accesorios CAN de Aces, paneles digitales y controladores de transmisión

¿Por qué Killshot Fusion? ¿Por qué Aces EFI?

Mientras otros enviaban diseños defectuosos para seguir una tendencia, Aces EFI se mantuvo firme, refinando, validando y probando hasta que tuvimos un producto digno de nuestro nombre. El Killshot Fusion es la culminación de cinco años de desarrollo de ECU y TBI, diseñado específicamente para un rendimiento en el mundo real y una fiabilidad a largo plazo.

Desde guerreros de fin de semana hasta sintonizadores serios, Killshot Fusion ofrece la confianza de una instalación limpia, el control de una sintonización de nivel profesional y el respaldo de una ingeniería probada.

Si está listo para un sistema EFI de cuerpo de aceleración que hace más que parecerlo, este es el suyo.

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?

My Aces Story: BUYER BE WARE

I purchased an Aces killshot fusion and tight tank pump module one month ago. $840. Installed per the instructions. Turned key on and it blew the fuel pump fuse. After testing with voltage meter, it turns out the fuel tank module was grounded on the positive post. Using rubber washers, I isolated the post and fixed the short to ground. Reinstalled the pump module. I noticed that even with key off, the fuel pump light was lit on the side of the throttle body. The fuel pump wire read 12.7v with key off and with key on it dropped to 2.5v on prime cycle then back to 12.7v. Talked to tech support and determined that grounded pump module shorted the fuel pump circuit on the ECM.

Sent it back for a warranty claim but change to a refund. Was refunded $566 out of my $840. So a $274 dollar lesson learned from me.

I DO NOT recommend these systems. Maybe I had bad luck but either way, I felt like people needed to hear this before they buy.

Easy install!

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.

10 out of 10!

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.

Really nice system

Hit the switch the first time and it fires right up. The old carb was junk and had to pump and prime about ten times to start but not anymore, it's a really great product. I've probably put 100 miles or so on it and it does really good!

R
Ruben

I think the carburetor will be fine. Customer service is not. I have called 3 to 4 times. And been on the phone on hold for over a hour and no answer. I think Customer services needs to be on point! Im a business owner my self and if i didnt answer the phone or put them on hold for over a hour i would be out of business! All im

saying is do better. I have have had questions and cant anyone to answer them.

The aces efi killshot is built amazing but trying to trouble shoot or get any customer service is joke this company is ridiculous for having an AI agent that can’t help you with anything and you can’t get a hold of a real person.

8" Handheld + Bluetooth Module / SB LA 273-360 / Tight Fit In-Tank Pump Module

I had been Reviewing Aces for a project and had determined that I liked what I was seeing. The Black Friday deals tipped me over the edge. I work in the driveway with no building so I have an installed it yet. However, I can say the packaging is substantial and the products in each box is very high quality. The 8-in screen is a spectacular although it may be a little too tall to fit my application. I wish the dimensions ran wider and narrower.

I bought one system worked great till the fuel pump stayed on all the time. Lack of tech support is why I gave 2 star. I had to order a second kill shot to get the customer out the door. System works great I just have an extra non working unit now and they haven’t responded to an emails or calls since nov 19th. Tech support takes an hour or more to even talk with someone. Then they ask is the 12v keyed.
