MALOSSI Force Master 3 Electronic Control Unit (Manufacturer Ref: 5519335) — a module designed for discerning scooter riders who want to fine-tune fuel injection management. The Force Master 3 intercepts the signal from the original lambda sensor and transmits a "virtual lambda" to the ECU, allowing for dynamic and personalized fuel mixture management between idle and transition zones. Ideal for urban environments on modern scooters equipped with a lambda sensor.

Designed to improve throttle response and linearity, the unit also corrects disturbances in the throttle position signal to refine the identification of the actual throttle opening and engine response times.

• Fuel mixture adjustment ±14% in LOW / MID / HIGH
• 8 selectable maps
• Lambda Emulator for continuous control between idle and transition
• RPM limiter: +1000 RPM (possibility to exclude speed limiter)
• Graphical display: firmware version, system status, switch positions
• Operating range: -20°C to +80°C, voltage 7–16 V, current < 200 mA, IP65 protection

Recommended for urban scooters (e.g., Vespa GTS/Sei Giorni 300 HPE) equipped with a lambda sensor. A MALOSSI product — for finer electronic management without altering the original architecture of the injection system.
