Show original supplier description
The Aces Fuel Injection Wild Card™ Sequential Multi-Port Injection EFI Kit offers advanced performance for your domestic V8 engine, delivering precise fuel metering for better air-fuel ratio control, improved cold starts, and enhanced throttle response across the entire RPM range. This translates to increased power and better fuel economy compared to traditional TBI systems. The kit features a 32-bit Power Architecture® self-learn ECU, an 8-injector setup capable of supporting up to 850 horsepower with 65 lb/hr injectors, and comes with a 5-inch handheld tuner with GPS speedometer. It includes a 255 L/PH inline external fuel pump, billet aluminum fuel filters, billet fuel pressure regulators, an oil gauge, and 20 feet of EFI-grade fuel hose. Optional intake manifolds are available in black or raw aluminum finishes. For more advanced tuning, laptop software is also available. The system utilizes dual Bosch LSU 4.9 wideband O2 sensors for precise fuel calibration of each cylinder bank and includes a Gambler series billet Cam Sync distributor for truly sequential injection and ignition control. The ECU itself supports injectors up to 500 lb/hr and is scalable for boost up to 315 kPa. The Wild Card 2 system seamlessly integrates with Dakota Digital clusters via the separately sold Aces BIM-01-2-ACES module. It outputs a tach signal for various gauge types and supports systems not relying on CAN data. However, if upgrading from an EFI system that uses CAN for gauge communication, compatibility should be reviewed before installation. The ECUs use automotive-grade 32-bit processors, ensuring fast and consistent signal management.
