To further optimize carburation and performance in transients, the use of the O2 controller is recommended. In the latest generation of motorcycles, the controller, thanks to the lambda sensor, is able to correct the amount of fuel that must be injected for carburetion to be constant, even in the Closed Loop area. The O2 controller allows the carburetion to be totally controlled to achieve an optimal air/fuel ratio. The Malossi Lambda emulator is a device that can simulate the lambda sensor signals that the vehicle's original ECU expects to receive. In this way, the original lambda sensor is used to obtain optimal carburetion, without the original ECU detecting faults or errors
