It is designed for fitment-specific replacement or tuning of the ignition control unit on selected small powersports vehicles, with a push-button setting interface and a digital curve display.\u003c\/p\u003e\n\u003ch2\u003eUnderstanding the 9 Selectable Ignition Curves\u003c\/h2\u003e\n\u003cp\u003eIgnition timing affects when the spark fires relative to piston movement. Changing the timing curve alters how spark advance progresses across engine operating conditions, and may change throttle response, pulling characteristics and riding feel. This CDI provides settings \u003cstrong\u003e1 through 9\u003c\/strong\u003e. The MOREV curve guide describes settings near Curve 1 as favoring later-range power delivery and settings near Curve 9 as emphasizing earlier response. These are alternative ignition maps, not nine fixed horsepower levels or an assurance of increased engine output.\u003c\/p\u003e\n\u003ch2\u003eFeatures \u0026amp; Controls\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNine adjustable maps:\u003c\/strong\u003e compare nine pre-programmed ignition timing curves to find the behavior suited to your engine.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEasy push-button selection:\u003c\/strong\u003e the built-in button changes the selected curve; the digital display shows the current setting.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLast-setting memory:\u003c\/strong\u003e the module recalls the last selected curve when restarted.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEngine-running adjustment support:\u003c\/strong\u003e settings can be changed after the engine has started; make changes only in a safe, stationary situation and follow the supplied operating guide.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecific DC electrical configuration:\u003c\/strong\u003e built for matching GY6 6-pin (4+2) DC CDI circuits; not interchangeable with AC modules.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eEngine Compatibility \u0026amp; Fitment Guide\u003c\/h2\u003e\n\u003cp\u003eIntended for selected \u003cstrong\u003eGY6-family 50cc–150cc four-stroke engines\u003c\/strong\u003e with the appropriate \u003cstrong\u003e6-pin (4+2) DC CDI connector and wiring\u003c\/strong\u003e.

It is not a replacement for a visually similar GY6 AC CDI. \u003cstrong\u003eThis specific product is the DC version only.\u003c\/strong\u003e The supplied GY6 terminal-side diagram illustrates a connector position shared by different AC and DC ignition configurations. For this DC CDI, \u003cstrong\u003eterminal 6 requires battery +12V DC\u003c\/strong\u003e, not the stator AC exciter output. The reference identifies terminal 1 as pickup\/trigger signal, terminal 2 as ignition coil output, terminals 3 and 4 as grounds, and terminal 5 as kill switch\/engine stop. Connect both grounds according to the product wiring reference, and verify your vehicle's actual harness orientation and pin assignments. \u003cstrong\u003eNever connect AC and DC ignition power sources together and never supply AC exciter voltage to this DC-only module.\u003c\/strong\u003e Turn off the vehicle and disconnect the power before installation. Verify ground, pickup\/pulse signal, ignition coil connection and the harness pinout against your original CDI. Incorrect wiring may result in no-start conditions or component damage; consult a qualified mechanic if the configuration is uncertain.\u003c\/p\u003e\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003ch3\u003eDoes every GY6 engine use this CDI?\u003c\/h3\u003e\n\u003cp\u003eNo. Engine-family names cover multiple ignition wiring systems.
