Malossi Force Master 3 Electronic Controller - Vespa GTS 300 - from 2019 - 5519335

Since our beloved scooters now have injection engines with an ECU that controls the fuel/oxygen ratio, you are limited in tuning the engine to ensure it delivers the performance you fully deserve.

Fortunately, the top experts at Malossi have a solution for this. By connecting the lambda sensor in the exhaust to this module, instead of the ECU, and then having this module provide a "corrected" lambda sensor signal to the ECU, the fuel mixture ratio can still be optimized.

You never went so fast!
