1. You can readjust the travel and dead zone of the throttle.2. Automatically switching the or TURBO mode.3. The /TURBO mode switching can be setting. Let the /TURBO two modes switch smoothly. It is a virtual electronic clutch.4. Throttle proportional can be set to change the throttle proportional characteristics.Throttle acceleration can be set to change the throttle response characteristics.5. The switch function can be multi-purpose configuration, It can be used for or function .. Use the plug to connecting without welding or damaging any circuit.6. This circuit is made according to Dualtron 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 Dualtron U2 scooter. The default meets the riding habits of most people. For needs, you can use this controller with touch screen module.Purpose:Note: (The screen and data cable can the controller and scooter, you can easily the function on the touch screen)Some high-power scooters can't turn off the front wheel motor, making the powerful power output difficult to handle and dangerous. This controller makes the high-power scooter much easier to control, without reducing , without limiting power, without limiting RPM, without reducing 100km acceleration time, without manually switching speed limit Settings, without manually switching mode, just like driving an electric car.Parameter:Input voltage: 9-15VInput signal analog 0-4.5Output signal analog 0-3.3Applicable: For scooters controlled by the analog voltage signal with EY3 odometer. Or you need to fy the yourselfColour:As shownMaterial:composite materialPackage Contents:1 x scooter throttle controller1 x data cable1 x screenOnly the above package content, other are not included.Note: Light reflection and different displays may cause the color of the item in the a little different from the real thing. The measurement allowed error is +/- 1-3cm.
