Polini ECM for Vespa and Liberty 50 Euro 5
Designed and upgraded as a result of Polini Racing Department feedback and development work, after many tests this Polini ECM upgrade allows a choice between 3 different maps, giving the rider custom performance options.
The Polini electronic ECM controls the engine and includes the connected sensors, the actuators, fuel injection, ignition and the engine auxiliary components. Allowing vehicle performance increases using latest generation microprocessors in synergy with model specific hardware, it is a fully reversible, easy install, plug & play ECM - just disconnect the original and connect this Polini replacement.
The easy-to-use maps selector is pre-loaded with 3 maps: Map 1 (Original Map) is specified to switch the vehicle to its original configuration, with factory engine, without any increase in engine rpm. This function is not applicable when oversized cylinder and valve springs are installed. Additions include optional Polini Hi-Speed variator with 5.8 g rollers and Polini muffler.
Map 2 is designed increase of the engine to 10,000 rpm, keeping the engine fully original. It is not mandatory to install the supplied valve springs, but Polini does recommend it. Additions with Map 2 also include optional Polini Hi-Speed variator with 5.8gr rollers and Polini muffler.
Map 3 allows the vehicle to reach a maximum speed of 70-75 km/h. With the additional installation of the Polini 49 mm diameter cylinder kit the engine capacity is increased to around 80 cc (140.0236). This needs to be combined with the Polini extended gear ratios (202.1429). It is also recommended to pair it with the Polini variator (241.737) and the Polini muffler (190.0079) and to replace all the original valves with those included in the package – essential for optimal results. It is 100% Made in Italy.
