AEB 549N Joker – programmable spark advance variator for 3-4-5-6-8 cylinder engines with coil ignition
Product Description:
Overview and function
The AEB 549N Joker is an electronic spark advance variator that operates directly on the negative coil terminal of certain electronic ignition systems. Designed for 3 to 8 cylinder engines, it automatically adjusts the ignition timing to improve engine performance, reduce fuel consumption, and minimize the risk of backfiring.
Technical Specifications
• Power supply voltage: 10 – 14 V DC
• Adjustable advance curves: 6° – 9° – 12° – 15°
• Advance disable at idle: via microswitch
• Advance disable on deceleration: via microswitch
• Compatible with: 3 – 8 cylinder engines with coil and distributor
• Certification: E10R-03
Benefits
• Enhances engine efficiency and response
• Lowers fuel consumption and emissions
• Prevents backfire on LPG and petrol systems
• Selectable advance curves for different engine types
• Compact and durable for professional installations
Installation and use
Mount vertically in a dry location away from heat. Connect the harness to the negative coil terminal. Choose the desired advance curve (6°, 9°, 12°, 15°) and configure the microswitch settings to disable advance at idle or during deceleration. Check system function after installation.
Application
Ideal for vehicles running on LPG, CNG, or petrol, and for installers or tuners needing a reliable timing advance processor for modern ignition systems.
