While the coil is actually just an energy storage device that supplies the ignition spark to the spark plug, the CDI module is a more complex component that controls the engine speed at which the spark should occur. It can therefore have an effect on engine behavior and performance.\u003c\/p\u003e\n\n\u003ch3\u003eOPEN CDI\u003c\/h3\u003e\n\n\u003cp\u003eMany riders equip their 50cc geared mopeds and scooters with open, i.e. derestricted CDIs. In most cases, the original CDI throttles the maximum achievable engine speed, which significantly reduces performance and top speed.\u003cbr\u003e\nTo remove this rev limiter and thus \u003cstrong\u003eincrease maximum speed\u003c\/strong\u003e, you can install a CDI without a rev limiter instead of the original CDI.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eBeware!\u003c\/strong\u003e When using an open CDI, the carburetor must be readjusted, so it is best to order new \u003ca href=\"https:\/\/www.scooter-attack.com\/en\/carburetor-and-intake\/jets\/?jet_position=main\"\u003ejets\u003c\/a\u003e as well.\u003c\/p\u003e\n\n\u003ch3\u003ePROGRAMMABLE CDI\u003c\/h3\u003e\n\n\u003cp\u003eProgrammable CDI control units are available for tuned racing engines on 50cc scooters and moorcycles as well as for motocross bikes. These CDIs are \u003cstrong\u003edesigned for more experienced tuners\u003c\/strong\u003e who want to optimize the settings of their two-wheeler as much as possible.\u003cbr\u003e\nWith a programmable CDI, the ignition timing is dynamic so that the spark always jumps at the optimum time at both high and low engine speeds.
