Product Info

The Joker 2 is a multiport EFI system with integrated CDI for classic, 8-cylinder 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 Joker 2’s high-voltage CDI system ensures maximum power and efficiency.

Why CDI?

Unlike traditional EFI systems that rely on weaker inductive ignition, Joker 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 Wild Card system, the Joker 2 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

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, Joker 2 EFI/CDI is the ultimate all-in-one ignition and fuel control solution. No need for a separate CDI box—Aces EFI is the only company to offer EFI and CDI in one ECU. If you’re serious about performance, The Joker 2 is the system you need!

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 minutes of idling and drive time, the system will build its own tune so you don't have to.

*Self-learning 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.

Interface Options

Our EFI systems are self-learning for most stock-to-mild engine builds. You’ll use one of the included interface modules (depending on the option selected at purchase) to complete the initial setup and make adjustments on the fly. The startup wizard will prompt you with 6–12 setup questions, after which the self-learn feature takes over.

Additional fine-tuning may be required later, depending on your specific build.
