4-pin CC-CDI ignition with adjustable DIP switches, compatible with universal high-performance ignition modules for motorcycles/ATVs/scooters with 50-125 cc displacement.

【Universal 4-Pin DC CDI for Small Engines】 This product is a 4-pin DC CDI ignition (capacitor ignition) for various small vehicles with engine displacements of 50cc, 70cc, 90cc, 110cc, and 125cc. It uses direct current (DC ignition, powered by a stable DC battery) and features an integrated, adjustable DIP switch. It is compatible with motorcycles, scooters, ATVs, and go-karts with 4-pin DC ignition systems, making it a versatile choice for repairs, replacements, or performance upgrades. Features include a 4-pin DC interface and an adjustable DIP switch. Interface type: Standard 4-pin interface, specifically designed for DC ignition systems (battery operation after connecting the power cable to the ignition switch). Advantages of DC Ignition: Compared to a CA-CDI, DC ignition delivers a more stable and intense spark at low RPMs, improving cold-start performance and low-end responsiveness. DIP Switch Adjustment: The integrated DIP switches allow you to switch between different preset ignition curves in various combinations to suit different riding styles and fuel types, or to remove the stock rev limiter. Common Modes: Economy Mode, Performance Mode, High-Rev Mode, etc. (See the user manual for details). 【Performance Optimization and Wide Compatibility】 Performance Enhancement: Offers more precise ignition timing and higher ignition energy, contributing to improved responsiveness, better acceleration, and a higher maximum engine RPM. High Adaptability: The DIP switch function allows you to adjust the performance to your actual needs, achieving an optimal balance between power and responsiveness. High Versatility: Compatible with most small single-cylinder engines with a 4-pin DC-CDI. 【Easy Installation (Important Points: Check System Type and Wiring)】 Two important checks are required for installation: System Type Check: Ensure your vehicle has a DC ignition system (the CDI is powered by the battery). Wiring Check: Carefully compare the 4-pin wiring described in the product manual (usually: Power +/Ground/Trigger/High Voltage Output) with your vehicle's original CDI wiring to ensure compatibility. Main Compatibility Range: Engine Displacement: 50cc, 70cc, 90cc, 110cc, 125cc. Vehicle Types: Scooters, Mopeds, ATVs, ATVs, Karts, etc. with a 4-pin DC CDI.
