Product Info
Overview
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!

How do I set up and program my system?
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.

Bluetooth Module
Compatible with Android and iOS devices and plugs into the CAN connection on the main harness.

5" Handheld (3rd Gen)
- Capacitive touch screen
- 64-bit processor
- 1280x720 resolution
- Cable connection via main harness

8" Handheld (1st Gen)
- Capacitive touch screen
- 64-bit processor
- 1280x800 resolution
- Wifi chip for software updates via the internet
- Cable connection via main harness
Most common questions
Quick answers to our most common queries for this product.
The The Joker 2 Sequential EFI/CDI Standalone System are designed to work with most stock or aftermarket ignition components. They will work with most tachometers and are compatible with Dakota Digital dashes using their Aces BIM Module (BIM-EFI-1).
Self-tuning is a common term used among aftermarket EFI companies, but we prefer the term "self-learning" as that is more accurate, even for our competitors who advertise "self-tuning."
Our systems are designed to self-learn the fuel MAPs and work best for stock-mild builds. Some mild builds and anything beyond that would require manual tuning, of which the system is fully capable. Additional features like nitrous and boost are also considered beyond stock and require manual adjustments to enable and configure these kinds of features.
Yes! You can make many changes using the Bluetooth or handheld interface, and we also offer a free PC app for more advanced tuning.
Yes to both! The The Joker 2 Sequential EFI/CDI Standalone System are compatible with both blow-through, draw-through, and nitrous applications and are also compatible with E85 Fuels. The The Joker 2 Sequential EFI/CDI Standalone System' MAP sensor can be scaled for up to 26 lbs of boost and can be set to retard timing.
Note that for boost, the system is compatible, but cannot control the boost. You will need to use a separate controller for things such as wastegate control or solenoid activation. Use of these features will require manual tuning.
