Power Distribution Module (PDM)
Discover the next evolution in performance and reliability with the Aces Fuel Injection Power Distribution Module (PDM) —your ultimate solution for seamless power management in high-performance EFI systems. The PDM uses IGBT transistors in the place of solid state or electro-mechanical relays which helps to filter bad transient voltage, ultimately providing greater protection for your electronics which are connected to the PDM.
Our PDM is engineered to integrate effortlessly with Aces Fuel Injection Systems, providing robust, efficient power distribution for essential components such as:
- Ignition Systems
- Fuel Pumps
- Cooling Fans
- Auxiliary Accessories
Key Features
- Comprehensive Power Management: Supports ignition, fuel pumps, fans, and more.
- Simplified Wiring: Clearly marked terminals for ease of installation.
- Enhanced Safety: Fuse-protected circuits for optimal performance and reliability.
- Flexibility: Tailored control for auxiliary devices with relay support.
Pressure Sensor Kit
Aces EFI pressure sensor kits utilize top-quality parts for use with EFI systems. Kits include plastic/steel sensors with 1/8" -27 NPT threads and include a -6 AN fuel pressure take-off adapter fitting and 2 sets of 45 push lock hose ends.
Pressure sensors are great for logging oil pressure, fuel pressure, or boost pressure. Display the pressure reading on any Aces Handheld or Dash screen and on your data log files!
Computing Power
A robust ECU that utilizes our OEM standard 32-bit architecture. This allows the system to manage input/output signals, voltage, and RPM faster and more consistently than our competitors.
Plug 'n' Play
Not a tuning wiz? You don't need to be since we provide a wizard for you. Our self-learning* functionality means you only have to answer a few basic questions in the startup wizard and then the ECU takes care of the rest. After about 30-60 mins of idling and drive time, the system will build it's own tune so you don't have to. Click here to learn more about our handhelds and dashes and see all of their features.
*Self-learn works best for stock-mild applications. For more aggressive applications and even some stock-mild applications, we offer free tuning software on our website.
"It Takes Two"
The Wild Card EFI system utilizes two WBO2 sensors to read each bank of your V8 engine. Dual wide-band sensors allow precise calibration of each cylinder bank, optimizing performance and allowing more thorough tuning of your engine without any compromises.

Description
Wild Card Sequential Multi-Port EFI System
Take your classic V8 engine into the modern era with Aces EFI' s Wild Card Sequential Multi-Port EFI System—a fully customizable, true sequential injection system designed for most classic 8-cylinder engines. Unlike traditional TBI setups or competitor systems that use bank-to-bank injection, Wild Card delivers precise fuel metering at each cylinder for superior throttle response, better fuel distribution, and increased power across the RPM range.
Total Customization for Your Build
Whether you' re running a Small Block, SBF, or even a Mopar (coming soon!), Wild Card' s customizable firing order setup in the start wizard ensures compatibility with a wide range of classic 8-cylinder engines. This system requires a 7+1 timing setup, ensuring accurate ignition control.
More Than Just EFI – A System Built for Performance
Wild Card is available in three configurations to match your build and power goals:
- Standalone System – Includes ECU, wiring harness, handheld controller, and basic sensors to get you running.
- Top-End Kits – Adds an aluminum intake manifold (black or raw finish), Gambler Series distributor, ignition coil, injectors, throttle body, and fuel rails for a complete fuel and ignition upgrade.
- Master Kits – Includes everything from the Top-End Kit plus a fuel delivery system of your choice for a full EFI conversion.
MP-EFI vs. TBI: Why Multi-Port is Superior
Throttle Body Injection (TBI) may be easy, but it can't compete with the precision of Multi-Port EFI (MP-EFI). TBI sprays fuel above the throttle blades, leading to uneven fuel distribution and weaker throttle response. In contrast, Wild Card' s true sequential MP-EFI meters fuel cylinder-by-cylinder, optimizing fuel economy, power, and drivability.
Built for Your Needs – Stock to High Performance
Power Levels: Available in 500 HP and 800 HP configurations.
Self-Learning: Stock to mild builds benefit from self-learning, while more aggressive setups can be manually tuned with our full tuning suite.
Injector Options: Choose between EV1 or EV6 style injector harnesses for compatibility with your fuel system.
Throttle Body Choices:
- 4-bbl throttle body includes a 1 BAR MAP sensor (for naturally aspirated applications).
- Single-blade throttle bodies come with a 2.6 BAR MAP sensor (for boosted applications).
Dual Wideband O2 Sensors: Ensures proper fueling across both banks for ultimate performance and efficiency.
Manifold Fitment: Designed for OEM block and head configurations (may not fit all aftermarket heads).
From daily drivers to track beasts, the Aces EFI Wild Card is the modern solution for your classic V8, offering unmatched precision, tunability, and performance. Upgrade to a smarter fuel injection system today and experience the difference of true sequential Multi-Port EFI!
Features:
- 32-bit software (OEM standard) that manages input/output signals, voltage, and RPM faster and more consistently than competitors.
- 5" full-color touchscreen handheld with built-in GPS speedometer.
- Integrated coil driver for ignition timing control (when using Aces' coil and distributor).
- Simple calibration wizard for initial setup - no laptop tuning required.
- Self-learning fuel table.

Marine Applications?
Is it marine or coast guard approved/certified? No. None of our products are.
Do we recommend it? No, since water and engines don't generally mix and warrantying items in these conditions becomes tricky. These are also modified applications that are not 100% what the systems were designed for.
Will it work? Yes, with some modifications for the WBO2 sensor.
Is it E85 compatible?
Yes, you just would need to change some settings first in order for it to work.
Please note that damages to the system caused by the use of E85 or other racing fuels are not covered by our warranty policy. This is because E85 is known to corrode certain types of material over time and our systems were not designed for long-term E85 use.
Will it work with aftermarket or stock gauges?
The system is not generally setup to work with stock gauges which is why we provide the handheld to display all the readings. Aftermarket tachometers will work with the system, and we are working to provide support for other popular aftermarket gauges soon!
What is your warranty policy?
All products have a limited one year warranty against any defects or quality of workmanship from date of purchase.
Our warranty is extended to the original consumer only. This limited warranty is not assignable or otherwise transferable. Customers must provide proof of purchase for warranty claims.
Aces' warranty does not apply to products, which have been:
- Modified or altered from factory condition.
- Subjected to adverse conditions, such as misuse, neglect, accident, improper installation or adjustment, dirt or other contaminants, water, or corrosion.
- Installed in other applications not recommended by Aces Fuel Injection.
What is your refund and return policy?
Aces Fuel Injection is happy to accept returns on orders returned to us inside our policy as long as they are new and unused. In general, items must be returned within 30 days for a full refund or within 60 days for a 10% restocking fee.
For our full Refund & Return Policy, that has all of the fine print, you can access it here.
What kind of tech support do you offer?
Aces offers general support on product setup, installation, troubleshooting, and basic diagnostic help.
While most stock-mild applications do not require tuning, some applications (usually more aggressive cams or boosted applications) may require additonal tuning beyond what the self-learn is capable of. Aces does not offer custom tuning though we can recommend Authorized Aces Tuners who typically charge a fee for their services. Read more about our support services and what to expect here.
