The Deuces Wild 2 is a 2-bbl throttle body EFI system for compact classic engines. Whether your classic car has a two-barrel intake flange, or you just want the advantages in lower-end torque and efficiency that a dual-barrel system offers, the Deuces Wild 2 has you covered. Utilizing 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.
Ignition Compatibility
Whether you’re running an HEI, canister coil, or aftermarket system, 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 seamlessly with Dakota Digital clusters using the Aces BIM-01-2-ACES module (sold separately). It outputs a clean tach signal for both factory and classic-style gauges and supports systems that don’t rely on CAN data.
If you’re moving from a stock or aftermarket EFI that uses CAN to drive your gauges, you may need to review those connections for compatibility.
Core Features
- Powered Up: Compatible with 350 naturally aspirated horsepower, and 300 hp when boosted.
- Remote-Mounted ECU: Unlike systems that bury electronics inside the throttle body, the Deuces Wild 2 keeps its ECU separate. This remote-mounted design protects it from heat and vibration, ensuring long-term reliability and easy serviceability.
- 4.9 WBO2 Sensor: Faster, more accurate readings with the latest planar sensing technology.
- Low-Profile Design: Works with more air cleaner setups (including drop-base filters) while fitting easily under most factory and aftermarket air cleaners.
- Self-Learning and Full Tuning: The Deuces Wild 2 ECU lets you get as involved as you want to be. Let the setup wizard learn from you as you drive, or manually tune for high-intensity applications. The choice is yours.
- Compatible with all Aces handhelds, dashboards, and modules
- Boost Compatible: Ready for boost and nitrous right out of the box. With upcoming software updates, you’ll gain access to full boost control for the perfect setup.
- Wired with the Aces Power Distribution Module by default: No more fragile relays.
Easy Weekend Install
For most applications, we built the Deuces Wild 2 to install in a weekend. No crew, no laptop wizardry. Bolt it on, wire it up, answer a few setup questions, and let it learn. From the first startup to full throttle, it’s designed to be as straightforward as EFI gets.
When you’re ready to leave the carb behind, the Deuces Wild 2 gives you everything you love about old-school performance with all the brains of modern EFI. Power, simplicity, and versatility: that’s the kind of combination you can only get by betting on Aces.

How do I set up and program my system?
Interface Options
Our EFI systems are self-learning for most stock-to-mild engine builds. You’ll use one of the included interface modules (depending on the option selected at purchase) to complete the initial setup and make adjustments on the fly. The startup wizard will prompt you with 6–12 setup questions, after which the self-learn feature takes over.
Additional fine-tuning may be required later, depending on your specific build.

Most common questions
Quick answers to our most common queries for this product.
The Deuces Wild 2 (2-bbl) EFI 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 (2-bbl) EFI are designed to work with most stock or aftermarket ignition components. They will work with most tachometers and are compatible with Dakota Digital dashes using their Aces BIM Module (BIM-EFI-1).
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 Deuces Wild 2 (2-bbl) EFI 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 Deuces Wild 2 Master Kits page here.
Yes to both! The Deuces Wild 2 (2-bbl) EFI are compatible with both blow-through, draw-through, and nitrous applications and are also compatible with E85 Fuels. The Deuces Wild 2 (2-bbl) EFI' 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.
Put this on a 22r for a quick replacement of a carb that needed rebuilt. Took a little bit of tuning . Recommend using advanced tuning software to get best results but . It runs at any angle .Dynoed 56hp wheel stock and after 76hp wheel. With a 1.00 weather correction factor at 8k ft. Runs good once tuned in . Pulling hiway passes much better. Tuning was actually not bad once I got thru the learning curve.
Put a efi throttle cable on and changed end of throttle linkage to mrgasket throttle linkage end. Worked good. Took a little porting of stock intake as seen below. Ran a walburo 450 pump 3/8 line and fuel filter. Aeromotive regulator and some an fittings. I drilled the stock manifold and tapped it to m18 1.5 pitch tap. Reads o2 perfectly
Purchased an ACES system because of a friend. He said their customer service was great and the product was simple to install. We had it installed in about 8-10 hours removing old systems and installing new. The handheld computer software was out of date so we ran the startup wizard through a PC Laptop. Next day we still had issues with the handheld, called customer service and the rep walked me through a couple of steps and the handheld worked perfect after that. We installed it on a Ford F100. Plenty of room for the original air box, but the mounting bolts were 1/4” too short easy trip to hardware store. So far we have approximately 200 miles on the system and it has worked well. Took a trip up the mountain and gained 3,000 feet and the truck didn’t miss a beat unlike when we had the carb in the truck. Only downside right now is a radio interference at WOT, static now plays loudly through the speakers. Gotta work through that as it wasn’t there before. Thank you Aces Team.
So far, everything has been great, the system is working great, and the pickup is running 10x better.
Great quick delivery.
Was a neat packaging, small dent on the box but everything seems fine so far.
very easy installation and my stock air filter assembly for my early Bronco fits perfect ,the only real draw back is that the carb studs supplied are way to short. the only bad part is my hand held's touch screen doesnt work and its a Saturday so ill have to wait till monday for help . the manuel should have a trouble shooting section
Installed on my 1985 Toyota Pickup 4x4 with a Built 22r, had a Weber 38DGAS. Thing is meant for much larger engine but with some tinkering and the absolutely Great customer service I managed to get this gorgeous TBI to work. It's never idled so smooth.
second aces install and i like this better than their four bbl just because it's not overkill on the air flow. runs like a charm but i wish they had an upgrade option for the 7 inch screen but its not out yet. Love their tech support though
