Polini - ECM map options with valve springs
Polini has updated its ECM ( Engine Control Module ) for Vespa , Liberty 50 and ZIP four-stroke Euro 5 - " the replacement of the control unit is essential for any type of set-up ," the company says . Designed and tuned as a result of testing , trials and development by the Polini racing department , the upgrade of the control unit allows the choice between three different mappings , " giving riders the opportunity to personalise their vehicle even more . " The addition of the valve springs inside the package allows the limiter to reach up to 10,000 engine rpm with a convincing and noticeable result in speed and an increase in performance that guarantees a more dynamic and fluid drive ". " The basic Map level 1 is the simplest assembly step , because you just remove the original control unit and connect the ' plug and play ' easy-install Polini ECM . By replacing this part only , it allows an increase in the rpm limiter with the engine going from 7,500 to 8,100 ". With this mapping , the odometer goes from 45 km / h to 50 / 53 km / h and Polini advise use of its variator (# 241.737 ) and muffler (# 190.0079 ) - but it is possible to use the factory Piaggio engine . The next level Map 2 is a dealer install that takes the performance up a level . First of all , it is necessary to change the original engine valve springs with the Polini ones included in the control unit package - these allow the engine limiter to be taken up to 10,000 rpm without valve problems . Polini also advises the use of its variator , muffler and its improved filter box coupling (# 223.0131 ), but it will work with the original engine . This set-up takes the speed from 45 km / h to 56 / 60 km / h . To replace the springs , it is necessary to disassemble the engine , but Polini says that the move directly up to Map level 3 - specific for Vespa and Liberty 50 - can be achieved for relatively little extra cost in relation to the improved performance . Polini says that this is the step to achieve maximum performance . The basis of this step is the 49 mm diameter cylinder kit , which brings the engine to about 80 cc (# 140.0223 ) - with the company ' s long gears (# 202.1424 ) mandatory for an optimal result . " Even with this mapping , it is advisable to combine the variator (# 241.737 ), the muffler (# 190.0079 ) and the improved filter box coupling (# 223.0131 ). Specific for the Euro 5 four-stroke ZIP , Map 4 also takes the maximum speed to 70 / 75 km / h . If the work has already been done to upgrade to Map 2 then , again , the additional cost for maximum , The basis of this step is the 49 mm diameter cylinder kit , which brings the engine to about 80 cc (# 140.0223 ) with the long gears (# 202.1429 ). It is also recommended to use the variator (# 241.737 ) and muffler (# 190.0079 ) with this mapping .
