Wild Card Series

The Aces EFI Wild Card series represents a step forward for domestic V8 engines, distinguishing itself as the ultimate choice for builders who demand more precise fuel metering than traditional throttle body setups can provide. While the Killshot, Deuces Wild, and Royal Flush families excel as Throttle Body Injection (TBI) systems that spray fuel from a central point above the throttle blades, the Wild Card series delivers a true, Sequential Multi-Port Electronic Fuel Injection (MPFI) architecture. By routing fuel through eight individual injectors located directly within the intake ports, it guarantees perfectly balanced fuel distribution across all cylinders, translating to crisper throttle response, cleaner cold starts, and minimized temperature variance. What makes this category truly unique among Aces' offerings is its ability to marry modern port injection with classic V8 architectures. Featuring dual wideband O2 sensors for independent bank-to-bank monitoring and a customizable firing order setup in the initial startup wizard, the Wild Card grants enthusiasts total tuning autonomy and precise fuel control that TBI systems simply cannot match.

The Joker Series

The Aces EFI Joker series is the perfect solution for builders who refuse to compromise on either precise fuel delivery or raw spark intensity. While it utilizes the same sequential Multi-Port Electronic Fuel Injection (MPFI) architecture found in the Wild Card series, the Joker distinguishes itself by integrating a high-output Capacitive Discharge Ignition (CDI) system directly into its 32-bit remote-mounted ECU. With this engineering advancement, builders can enjoy elite sequential fuel and ignition control within a single, cohesive unit, completely eliminating the clutter and wiring headache of a separate CDI box. By generating an intensely hot 150mJ spark, the Joker ensures complete, efficient combustion even in the most demanding high-compression, forced-induction, or aggressive nitrous applications. When this spark energy is combined with dual wideband O2 sensors and fuel injectors firing precisely in sequence with each cylinder's intake valve, builders are granted unparalleled, granular control over their engine's power output.
