Just installed a wildcard 2 on my 1933 ford pickup street rod. Have not driven yet but is running. Very excited to have this on here. I think it really going to wake this Sbc 355 up!

The Aces Wild Card 2 is a fully customizable, true Sequential Multi-Port EFI (MPEFI) system engineered for classic 8-cylinder engines. Unlike traditional TBI setups or aftermarket systems that use bank-to-bank injection, the Wild Card 2 delivers precise fuel metering to each cylinder, giving you superior throttle response, balanced fuel distribution, and more power across the RPM range.
Total Customization for Your Build
Every classic V8 is unique, and the Wild Card 2 is designed to adapt to yours. Its customizable firing order setup in the startup wizard ensures compatibility with a wide range of classic 8-cylinder engines. This system requires a 7+1 Hall-effect distributor, providing accurate crank and cam signal synchronization for true sequential injection and precise ignition control.
Ignition Compatibility
The Wild Card 2 is built around precise ignition control and requires a 7+1 Hall-effect distributor for sequential timing (available in Top End & Master Kits).
If you want a fully matched system, Aces offers Hall-effect distributors, ignition coils, and fuel systems designed to work together for maximum spark control and reliability.
Core Features
- Self-learning and full tuning capability
- Expanded 31 x 31 tuning tables
- Power Levels: Available in pre-built 500 HP and 800 HP kits, but in reality, the system’s capability is only limited by your supporting hardware (injectors, throttle body, and fuel system). The ECU itself is compatible with injectors up to 500 lb/hr, and scalable for boost up to 315 kPa, giving you headroom for serious horsepower builds. Truly, a system for the people.
- Self-Learning: Stock-most mild street builds benefit from the self-learning ECU; more aggressive setups can be manually tuned using our free laptop software.
- Injector Options: Choose between EV1 or EV6 injector harnesses to match your fuel injectors. (Top End & Master Kits come with EV1 by default)
- Throttle Body Choices: When buying a Top End or Master Kit:
- 4-barrel throttle body with 1.0 BAR MAP Sensor
- Single-blade throttle with 2.7 BAR MAP Sensor
- Dual Wideband O₂ Sensors: Maintain balanced fueling across both banks (both of which are 31x31) for ultimate precision and safety.
- Manifold Fitment: (in Top End & Master Kits) Designed for OEM-style block and head configurations (fitment may vary with some aftermarket heads).
It’s already compatible with blow-through, draw-through, and nitrous setups right out of the box. And when our PWM boost control update lands soon, the hardware is already ready to go for true boost precision.
When you’re ready to leave outdated fuel systems behind, the Wild Card 2 gives you everything you love about old-school performance with the intelligence of modern EFI. Power, reliability, 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.
Bluetooth Module
Compatible with Android and iOS devices and plugs into the CAN connection on the main harness.
5" Handheld (3rd Gen)
- Capacitive touch screen
- 64-bit processor
- 1280x720 resolution
- Cable connection via main harness
8" Handheld (1st Gen)
- Capacitive touch screen
- 64-bit processor
- 1280x800 resolution
- Wifi chip for software updates via the internet
- Cable connection via main harness
Most common questions
Quick answers to our most common queries for this product.
The Wild Card 2 EFI (Standalone) 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.
Yes to both! The Wild Card 2 EFI (Standalone) are compatible with both blow-through, draw-through, and nitrous applications and are also compatible with E85 Fuels. The Wild Card 2 EFI (Standalone) ' 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 control the boost. 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.
This product has no reviews of its own. The merchant grouped it with related products, so the reviews shown are from across that group.

Worst customer service imaginable. Throttle position sensor and a few other small parts were missing from my kit. No big deal, just make it right and send the parts you forgot…nope! Been a month now and they still won’t ship me the missing parts from my order. Every email response says the exact same thing like it’s scripted. Been told it’s being “escalated to the proper team” 6 times between emails and phone calls. I’ve never received a single bit of communication back without initiating it first. I’ve given up, I purchased a throttle position sensor and the other parts so I can hopefully use this $2,000 paperweight. This could end up being the best EFI system ever and I still won’t buy another based on the service alone. Sad, I had high hopes for Aces before this.

I installed the wildcard on my blueprint 5.0l 302 sbf. I followed the instructions exactly for the install and wiring. Went through the setup procedure on the handheld and my 1972 Bronco came to life. I then did a remote tune with one of their recommended tuners (Bryant Stilwell) and I have about 500 miles on it with no issues! I would definitely install another on a future build.

Items are great, shipping is a little slow but overall great value.

Nice complete system, looks great.

SBC Top End Kit with (Silver) SBC Manifold / 500 / 5" Handheld
It's still on the shelf, I have to pull my big motor out, then install my smaller one when we pull it from my buddy's car. After installing and dyno testing, I'll get back to you. If you have any interest in observing the tuning on the dyno at Westech Performance, let me know, We do a lot of videos there at the former home of Engine Masters. Anything new you want to get seen?
Maybe put something together for all of us to benefit??

Awesom sale. Very well packaged nice quality this is my second aces product.

255 In-line Fuel Pump System w/40' PTFE Hose / Black Manifold for SBC (non-vortec) / 5" Handheld
Well I received the wrong injectors and no hardware for the manifold so after waiting for the kit to show up now waiting for the right parts before can even start installing. I understand things happen but it took 3 calls (3 different people), 2 days to get a 50/50 feeling that everything is on the way. The last person was very helpful and assured me everything would be sent out so just waiting. Otherwise I'm super excited to get it installed and see how it performs. Installation manual is lacking a lot of key details, and Ace's videos also skip a lot of key details with the exception of the distributor, which is helpful but left in the dark about so many other things. Since there's so many questions unanswered I've called in only to get customer service person with no tech knowledge or even a basic understanding about the product that I bought so they give out generic info that doesn't make sense in the real world so I'm left with spending hours researching on my own how to install your product.

Everything fit well kit was very self explanatory and package was delivered without damage! Thank you
