Malossi Lambda Sensor Emulator – Manufacturer Ref: 5519172B
Designed for modern machines equipped with a lambda sensor, this Malossi emulator replicates the signal expected by the original ECU to avoid errors related to injection management. Installed as a replacement or in parallel to the sensor, it allows the original unit to continue functioning without triggering faults, while providing the opportunity to adjust the fuel mixture according to track or testing needs.
The Lambda Sensor Emulator is aimed at riders and tuners who wish to control the closed loop of their engine management during modifications to intake, exhaust, or mapping. Its use is common in urban, roadster, and off-road/cross contexts where injection regulation may be hindered by modifications not accounted for by the original ECU.
Examples of applications: YAMAHA T-MAX 560 TECH MAX (2025), FANTIC XE 125 (2024), BETA RR 125 4T ENDURO LC (2021). For safe installation, have the assembly done by a professional or carefully follow the manufacturer's instructions.
