1. The product power is set to 8 at the factory, which basically corresponds to most split superchargers on the market. If the customer uses an integrated supercharger, please set it to 12.
2. P13 in the manual is the power setting of the product. If the supercharger is incompatible, the customer needs to adjust it to 8 or 12.
3. Please note that the controller model is sent randomly. Please confirm whether you are satisfied before placing an order.
How to use: After getting the product, please be sure to align the phase first: plug in the smart identification line and identify the motor. The identification line is two green lines. After plugging in, pay attention to suspend the car, and the motor will run automatically. At this time, if the direction of rotation of the motor is correct, run for 10 to 15 seconds, disconnect the identification line, if the direction is opposite, disconnect the identification line and plug it back, the motor direction will change to forward, run for another 10 to 15 seconds, disconnect the identification line, and the motor direction will change to forward. Run for another 10-15 seconds, disconnect the identification line, and the motor direction will change to forward. Run for another 10-15 seconds, disconnect the identification line, and it's done. After the identification is completed, the identification line remains disconnected, do not plug it back

Controller Introduction
This controller is FCO sine wave design for brushless motor with hall sensor.
Brushless Hall motors are 3+5 wire or 3+6 wire, these two types of motors are best suited for Forever FOC controllers.
This controller is suitable for electric scooters as well as electric bikes, it is very compatible and designed for modification users and repair shops.
This controller has self-learning design, when you install it for the first time, there may be motor jitter, this is normal because the controller doesn't detect your motor parameter, you can short the self-learning wire for 5 seconds, the controller will automatically check your motor parameter and auto-compatible.
The advantage of this design is that the controller is compatible with almost all brushless motors. Many single mode sine wave controllers on the market do not have self-learning wires, and this controller is designed with self-learning motors to perfectly solve this problem that bothers users.
Please don't need to worry if your motor drives in reverse direction after initial installation, this is normal, you can short connect the self-learning wire to change the initial direction of the motor.
If you want accurate LCD speed display, you can enter LCD setting mode and set your motor wheel diameter in P06 in inch.
Set the speed magnet in P07, normally you can set it to 23,.
After setting P06 and P07, you can test the real time speed with map navigation APP, if the LCD display speed is bigger than the navigation display speed, then you can reduce the parameter of P07 to lower the speed display ratio.
If the LCD display speed is less than the navigation display speed, you can increase the parameter in P07 to increase the speed display ratio. After finding the exact speed that suits you in this way, you will see the LCD displaying the exact speed.
