Each of the nine selectable maps changes the timing progression under different operating conditions, which can influence low-speed pickup, throttle response and higher-range power delivery. According to the MOREV curve reference, settings near \u003cstrong\u003eCurve 1\u003c\/strong\u003e tend to emphasize later-range delivery, while settings near \u003cstrong\u003eCurve 9\u003c\/strong\u003e emphasize earlier response. These are different ignition timing profiles, not fixed speed settings or guaranteed horsepower increases. The best curve depends on the engine build, ignition components, fuel quality and riding conditions.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCurve settings run from 1 through 9; there is no setting 0.\u003c\/strong\u003e The unit remembers the previously chosen curve after shutdown. Although the curve can be changed after starting the engine, make adjustments only when the vehicle is safely stationary.\u003c\/p\u003e\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003eDesigned for \u003cstrong\u003eselect 50cc, 70cc, 90cc, 110cc and 125cc four-stroke horizontal-engine\u003c\/strong\u003e ATV, pit bike, dirt bike and go-kart applications using a compatible 5-pin AC CDI.

Pinouts may differ between vehicles that appear to use the same connector; compare the wiring arrangement, original unit and dimensions before installation. Incorrect connections may prevent starting or damage ignition components. If uncertain, ask a qualified technician to verify compatibility. Results depend on engine condition and the complete ignition setup.\u003c\/p\u003e\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003ch3\u003eWill this work with a 5-pin DC CDI?\u003c\/h3\u003e\u003cp\u003eNo. This model is designed for a compatible \u003cstrong\u003e5-pin AC CDI\u003c\/strong\u003e ignition circuit, not a DC system. Match the original CDI and harness wiring before purchase.\u003c\/p\u003e\n\u003ch3\u003eCan I use this on any 125cc dirt bike?\u003c\/h3\u003e\u003cp\u003eNo. Displacement alone does not determine CDI compatibility. Check the engine family, AC power supply, connector style and pinout.\u003c\/p\u003e\n\u003ch3\u003eWhat is the difference between curves 1 and 9?\u003c\/h3\u003e\u003cp\u003eThe available ignition timing profiles differ in how spark timing advances through engine operation. Consult the supplied MOREV curve guide for the exact map shapes; select the curve based on how your engine responds.\u003c\/p\u003e\n\u003ch3\u003eDoes the CDI save my selected curve?\u003c\/h3\u003e\u003cp\u003eYes. It retains the last selected ignition curve when the engine is switched off.\u003c\/p\u003e\n\u003ch3\u003eDoes this CDI offer the same speed-limit modes as the MOREV DIP CDI?\u003c\/h3\u003e\u003cp\u003eNo. This 9-curve model adjusts ignition timing maps and is a different product from the DIP-switch speed-limit series.\u003c\/p\u003e\n\u003ch2\u003eShipping\u003c\/h2\u003e\n\u003cp\u003eOrders ship from \u003cstrong\u003eGuangzhou, China\u003c\/strong\u003e.
