The stepper motor is not working

Post by 1204257363@qq.com »

I used rusefi plate throttle with stepper motor on the motorcycle, and set the stepper motor function Dan on the debugging software. The motor can only work one-way and does not return. What is the problem

I'm really sorry for the wrong expression. Now the stepper motor problem has been solved by updating the latest firmware. Now I find that the maximum speed limiter can only be 12750RPM, and the maximum speed of my motorcycle carburetor is 18000.

Does it support Bluetooth wireless connectivity? USB connection is easy to drop when the engine is working

Yes, but it would be worse.

Please start providing much more info. Pictures of hardware, pictures of wiring, etc etc.

The setting of ejection can only be default. Other options will be automatically restored to "Simultaneously" after the ECU is powered off. Other options cannot be saved
