The ECM with Polini Valve Springs for Aprilia SXR 50 4T E5 has been studied and developed by Polini racing department after numerous tests and trials. The upgrade of the Polini control unit allows the choice between three different maps, offering the possibility of further personalizing your vehicle. The addition of the valve springs inside the package allows the limiter to reach up to 10.000 rpm, with a concrete result in speed and an increase in performance ensuring a more dynamic and fluid ride. Depending on the assembly steps of the scooter, it is important to match the specific mapdeveloped by Polini. MAP 1 This is the simplest assembly step, as it is sufficient to remove the original control unit and connect the Polini ECM, as it is plug & play and easy to mount. Its replacement allows an increase in the rpm limiter with the engine going from 7.500 to 8.600. With this map it is recommended to combine the Polini variator (VP241737), maintaining the original Piaggio engine with original valve springs. Thanks to map 1 the odometer goes from 45 km/h to 50/53 km/h. .MAP 2 With the second map we get to the heart of customization, and it takes your vehicle to a higher level. It is essential to rely on a professional as you work directly on the engine. It is important to know that it is necessary to change the original engine valve springs with the Polini ones (already included in the control unit package), which allow the engine limiter to be brought to 10.000 rpm without causing problems to the valves. With this map it is recommended to combine the Polini variator (VP241737), which can also be mounted on the original engine. Thanks to the second step we go from 45 km/h to 54/55 km/h.Please note - To replace the springs it is necessary to disassemble the engine: with a small additional step in terms of costs it is possible to change directly to Map 3, obtaining a more performing final result. .MAP 3 With the third step you achieve the maximum performance, at the basis of this step there is the 49 mm diameter cylinder kit which brings the engine to approximately 80 cc(VP400237) with the Polini long gears (VP021430) mandatory for an optimal result with this map it is recommended to combine the Polini variator (VP241737).
