Foxflash ECU Chip Tuning Tool can be used to read ECU via hotspot when you are outside. It’s easy to make this true. Just use the cigarette lighter to power the foxflash tool in the car, and connect the computer with WiFi via hotspot on your mobile phone.
The operation guide (word & image):
Plug the cigarette lighter into the cigarette lighter plug on the car
And connect the other end of the cigarette lighter to the Bench Box to supply power
Connect foxflash ECU programmer and computer via the USB cable
Next turn on the computer to operate
The foxflash software cannot be opened when the computer is not connected to the internet.
So turn on the personal hotspot on your smartphone
Use the laptop to find the same name of the WiFi hotspot which is turned on by the phone

If it shows the WiFi hotspot is connected, you can open the foxflash software and log in with SN to read the ECU normally.
