Royal Flush 2 EFI/CDI Master Kits (Black)

The Royal Flush 2 is a 4-bbl throttle body EFI system with integrated CDI for classic engines. Aces is the only EFI manufacturer to produce integrated Capacitive Discharge Ignition (CDI) setups: no costly additional purchases Whether you're running high compression, forced induction, or aggressive racing setups, the Royal Flush 2’s high-voltage CDI system ensures maximum power and efficiency. Why CDI? Unlike traditional EFI systems that rely on weaker inductive ignition, Royal Flush 2’s CDI system produces a hotter, more consistent spark that burns fuel more efficiently, leading to: Superior combustion in high-boost or high-compression applications Increased power and throttle response Reduced misfires and improved fuel efficiency Total Control for Performance Builds Just like our Killshot system, the Royal Flush 2 EFI/CDI works with most classic engines with a 4150 intake flange. But what sets Royal Flush 2 apart is its built-in CDI technology and racing-grade features: Integrated Digital CDI – Produces 150mJ spark energy output for maximum ignition performance Massive Voltage Output – Primary voltage: 450-530V / Secondary voltage: 50,000V 2-Stage Rev Limiter – Set a max RPM limit for engine protection, plus launch control for optimal starts Burnout Mode – Holds RPM at a set limit for consistent, controlled burnouts Core Features Self-learning and full tuning capability Expanded 31 x 31 tuning tables Integrated digital CDI with 150mj spark energy output 2-stage Rev limiter setting for max RPM, launch control, and burn out 32-bit software (OEM standard) that manages input/output signals, voltage, and RPM faster and more consistently than competitors Easy setup and monitoring with your choice of bluetooth module or HD handheld Integrated coil driver for ignition timing control (when using Aces’ coil and distributor) Simple calibration wizard for initial setup- no laptop tuning required. Dual fan control Step retard for nitrous control Boost compatibility right out of the box, with boost control coming soon Free laptop software available for pro applications Compatible with all Aces’ handhelds, dashes, and modules Dual 4.9 WBO2 sensors From street builds to high-boost race cars, Royal Flush 2 EFI/CDI is the ultimate all-in-one ignition and fuel control solution.
