Features: 1. You can readjust the travel and dead zone of the throttle. 2. Automatically switching the ECO or TURBO mode. 3. The ECO/TURBO mode switching point can be setting. Let the ECO/TURBO two modes switch smoothly. It is a virtual electronic clutch. 4. Throttle proportional curve can be set to change the throttle proportional characteristics.Throttle acceleration curve can be set to change the throttle response characteristics. 5. The ECO switch function can be multi-purpose configuration, It can be used for curve selection or function selection.. Use the plug to connecting without welding or damaging any circuit. 6. This circuit is made according to U2 cable, and the odometer is EY3. This circuit only samples the analog handle signal and outputs the adjusted analog signal. Theoretically, all electric scooters can be modified. 7. The default parameter of this controller is optimized for U2 scooter. The default program meets the riding habits of most people. For special needs, you can use this controller with our touch screen module. Name:scooter throttle controller+screen Kit Input voltage: 9-15V Input signal analog 0-4.5 Output signal analog 0-3.3 Applicable: For scooters controlled by the analog voltage signal with EY3 odometer. Or you need to modify yourself Purpose: Note: (The screen and data cable can program the controller and scooter, you can easily program the function on the touch screen) Color: As Shown Material: Plastic + PCB board Package Contents: 1 x scooter throttle controller 1 x data cable 1 x screen Only the above package content, other products are not included.
