Overview
The Aces Deuces Wild 2 isn’t just an upgrade, it’s a statement.
Built for the driver who refuses to settle, this 2-barrel throttle body EFI system replaces your carb or outdated EFI with modern precision and raw power. Using a 2300-style flange and a recessed base, it drops right onto single or dual-plane manifolds. With support for up to 350 HP naturally aspirated and 300 HP under boost, the Deuces Wild 2 is made to feed whatever you’re building: street bruiser, boosted weekend warrior, or nitrous-hungry drag car.
An integrated 3-bar TMAP sensor supports up to 27 psi of boost for turbo and supercharged applications, while two 100 lb/hr injectors comfortably feed up to 350 HP. It’s already compatible with blow-through, draw-through, and nitrous setups right out of the box. And when our boost control software update lands in Fall 2025, the hardware inside is already ready to run with PWM boost solenoid control for true precision under pressure.
Power Meets Simplicity
At Aces, we build EFI systems that make serious power simple.
The Deuces Wild 2 is a DIY-friendly system designed for enthusiasts of all skill levels. Wire it in, answer a few setup questions, fire it up, and the self-learning ECU takes over by fine-tuning your fuel maps automatically. For most street builds, that’s all it takes. For the tuners who want total control, our free laptop software unlocks full manual tuning access, which is ideal for mild to aggressive builds running high-lift cams, forced induction, or nitrous.
Once your engine reaches operating temperature, the system goes closed-loop and starts learning in real time. After a few drives, your tune dials itself in, and when you’re happy with it, you can disable learning and lock it down. That’s confidence you can feel at every throttle blip.
Ignition Compatibility
Whether you’re running an HEI, canister coil, or aftermarket system like MSD or Holley, the Deuces Wild 2 plays nice. It can also digitally control timing with a Hall-effect or mechanically locked magnetic distributor and works seamlessly with CD ignition boxes.
If you’re looking to go all-in, Aces offers complete Hall-effect and magnetic distributors, ignition coils, and fuel systems designed to work together for maximum reliability and spark control.

System Integration
The Deuces Wild 2 connects with Dakota Digital clusters using the Aces BIM-01-2-ACES module. It outputs a clean tach signal for factory and classic gauges and supports systems not relying on CAN data.
If moving from an EFI system that uses CAN to drive gauges, review connections for compatibility.
All Aces ECUs use 32-bit automotive-grade processors—same-class hardware used by OEMs.
The system runs at 43–60 PSI and supports return or returnless configurations depending on pump type.
Easy Weekend Install
For most applications, the Deuces Wild 2 installs in a weekend. Bolt it on, wire it up, answer setup prompts, and let it learn. Simple, modern EFI performance without the headaches.
No compromises. No headaches. Just results.

Most common questions
Quick answers to our most common queries for this product.
The Deuces Wild 2 Fuel Kits are designed to work with any classic 4, 6, or 8 cylinder engine that is under 350 hp, uses a 2300 style flange, and has a fuel system rated for EFI (43 PSI).
The self learn will work for most stock-mild builds, while some mild and more advanced builds may require manual tuning.
The Deuces Wild 2 Fuel Kits are designed to work with most stock or aftermarket ignition components. It will work with most tachometers and is compatible with Dakota Digital dashes using their Aces BIM Module (BIM-01-2-ACES).
Self-tuning is a common term used among aftermarket EFI companies, but we prefer the term "self-learning" as that is more accurate, even for our competitors who advertise "self-tuning."
Our systems are designed to self-learn the fuel MAPs and work best for stock-mild builds. Some mild builds and anything beyond that would require manual tuning, of which the system is fully capable. Additional features like nitrous and boost are also considered beyond stock and require manual adjustments to enable and configure these kinds of features.
Yes! You can make many changes using the Bluetooth or handheld interface, and we also offer a free PC app for more advanced tuning.
The Killshot Fusion can work with standard stock or aftermarket ignition components, but if you want to run timing control, it will need either a magnetic pickup distributor that has been locked out or a Hall Effect distributor. You will also need to make sure that your fuel delivery system can support 43-58 PSI. Whether or not you need a return line will depend on your fuel delivery system and if the regulator is inside or outside the tank. Whether or not you need to replace your tank will depend on which fuel delivery system you choose. We offer complete Master Kits for each EFI system that come with new ignition components and a fuel delivery system. You can visit the Killshot Fusion Master Kits page here.
Yes to both! The Deuces Wild 2 Fuel Kits are compatible with both blow-through, draw-through, and nitrous applications and is also compatible with E85 Fuels. The Deuces Wild's MAP sensor can be scaled for up to 26 lbs of boost and can be set to retard timing.
Note that for boost, the system is compatible, but cannot currently control boost. The system has the hardware for boost control, which is coming via a free software update by Spring of 2026, but for now, you will need to use a separate controller for things such as wastegate control or solenoid activation. Use of these features will require manual tuning.
