Joker EFI/CDI - The Most Powerful Multi-Port EFI SystemTake your high-performance or boosted V8 to the next level with ACES EFI’s Joker EFI/CDIthe most powerful Multi-Port EFI system on the market! The Joker is the only EFI system that integrates a Digital Capacitive Discharge Ignition (DCDI) system inside the ECU, delivering unmatched spark energy, precision, and control. Whether you're running high compression, forced induction, or aggressive racing setups, the Joker’s high-voltage CDI system ensures maximum power and efficiency.
What Makes Joker EFI/CDI Unique? Unlike traditional EFI systems that rely on weaker inductive ignition, Joker’s CDI system produces a hotter, more consistent spark that burns fuel more efficiently, leading to: Superior combustion in high-boost or high-compression applicationsIncreased power and throttle responseReduced misfires and improved fuel efficiency
Total Control for Performance Builds: Just like our Wild Card system, the Joker EFI/CDI works with most classic 8-cylinder engines, offering a customizable firing order in the start wizard and requiring a 7+1 timing setup for accurate ignition control.
But what sets Joker 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
Self-Learning: Stock to mild builds benefit from automatic tuning, while high-performance setups require custom tuning
Dual Wideband O2 Sensors: Ensures proper fueling across both banks for ultimate performance.
From street builds to high-boost race cars, Joker EFI/CDI is the ultimate all-in-one ignition and fuel control solution. No need for a separate CDI boxAces EFI is the only company to offer EFI and CDI in one ECU. If you’re serious about performance, The Joker is the system you need!
