Upon our professional electronic engineers' carefully designing,a new type of CDI has come out.The starting speed is faster than the original design.The ignition angle is precise at the medium and hign speed,which improves the engine's power and saves more fuel.This kind of CDI applies to the improved racing motorcycle and high-speed pursuer. Using digital circuit ignition MCU, accurate control, ignition timing accurate to 0.1 °, spark strong energy, easy to start, accelerating speed, smooth, satisfied at different speeds for drivers of engine power demand. Ignition shell, and plug the car ignition.
