Description Open CDI Polini for Vespa Primavera / Sprint iGet Euro 5CDI unit Polini for Vespa Primavera / Sprint 50cc 3V 4T iGet (`20-) Euro5 / PIAGGIO Liberty 50cc 3V 4T iGet (`20-) Euro5. Also serves as a replacement CDI for the P171.0009derestriction kit.What are the benefits of an open CDI?Original 50cc engines are heavily restricted ex works, an open CDI can be used to remedy this. The ECU / ECM control unit regulates the amount of fuel delivered by the injection module via pre-programmed parameters and optimizes the ignition timing. In addition, the rev limiter only kicks in from 10,000 rpm. Optimized ignition and injection curves ensure a clearly noticeable increase in performance.CDI mappingsMapping 1 : Can be installed plug & play - RPM limiter from 8,100 rpmMapping: 2 +3: Use with supplied valve springs - RPM limiter from 10,000 rpmTo ensure optimum operation of the CDI, we recommend installing a sports CVT and an open intake hose, or ordering the complete derestriction kit P171.0009.

Notes and Safety CDI and coilThe CDI (for Capacitor Discharger Ignition) and the ignition coil are an essential part of the ignition. 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.Open CDIMany 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. To remove this rev limiter and thus increase maxim
