The EasyFlash is EasyTune's OBD-II interface. It plugs into the vehicle's OBD-II port and connects to your computer over USB-C, or without a cable over Bluetooth or Wi-Fi.
Drag to turn it, and click Explode to take it apart. Click a part, on the model or in the list, to see what it does. The parts inside are an illustration, not the real circuit board.
- Download the EasyFlash app from the download page and install it. On Windows it also installs the driver the EasyTune App uses to talk to the EasyFlash.
- Plug the EasyFlash into your computer with a USB-C cable and open the EasyFlash app. Use it to keep the EasyFlash's firmware up to date.
- Plug the EasyFlash into the vehicle's OBD-II port, and connect from the EasyTune App. See Vehicle Connect.
- CAN: talks to the ECU over the vehicle's CAN bus.
- K-line: talks to older ECUs over the K-line.
- Storage: keeps files on the interface, so it can run a job, such as a flash, by itself.
- Bluetooth and Wi-Fi: connects without a cable. See Bluetooth and Wi-Fi.
- Power: runs off the vehicle's battery through the OBD-II port, or off USB.
The two lights on the back show what the EasyFlash is doing. See Lights.
The button next to them approves Bluetooth pairing, and holding it restarts the EasyFlash into its factory firmware. See Button.
The EasyFlash goes to sleep when all of these are true for long enough:
- There's no vehicle power, below 9 V, for 30 seconds.
- Nothing has talked to it for 10 seconds, and it isn't running a job.
- It isn't plugged into a computer.
The red light flashes quickly just before it sleeps. It wakes every 30 seconds to check the power, and starts up again once it's back on a vehicle's power.
