Polini Lambda Emulator- Yamaha Aerox 50cc 4-Stroke


Add to Basket

Polini lambda sensor emulator for Yamaha Aerox 50cc 4-stroke scooters produced 2018 onward.

Lambda sensors tell the ECU what air/fuel ratio the bike is running at, this allows the ECU to adjust accordingly for economy. Polini have bypassed this system with their emulator, the emulator tells the ECU it's own predetermined "AFR" allowing the bike to achieve improved performance. Included are instructions to bypass the speed limiter and modify the air box.

To further exploit the emulator Polini recommend fitting HI-SPEED variator 241.746.
