The speed unlock chip for Yamaha Booster Easy has been designed to remove the engine lock at 25 km/h and maintain assistance up to 75 km/h (theoretical). Installation is simple and quick and is also totally invisible as the internal space of the crankcase is used to house it. The connectors are plug-ins made with advanced molding technology and click when properly inserted. Engine unlocking is activated/deactivated by pressing the lights button.

The Speed Unlocker functionality is available with an in-app purchase of €0.99. Without the purchase in the app the unlock function DOES NOT work.

The Eplus Tuning app allows you to:

- Change the engine maps (6 different maps from Eco to Race)
- Unlock the speed
- View data in real time
- Set the wheel size from 2000 mm to 3000 mm
- Activate the Code Immobilizer, which prevents the engine from being activated
- Set the speed to a value of up to 75 km/h (theoretical)
- Set the active unlocking when the bike is turned on

Compatible only with Yamaha BoosterEasy

Attention! Check that the connectors of your e-bike correspond to those in the photo!

ATTENTION! READ CAREFULLY THE ASSEMBLY INSTRUCTIONS AND THE USER MANUAL THAT CAN BE DOWNLOADED FROM THE BUTTON IN THE BAR BELOW
