Connect your Severn Tuning K+DCAN (OBD to USB) cable to your computer's USB port

Connect your Severn Tuning cable to your car's OBD port

Insert your key and turn the ignition switch to "Run". Do not start the engine!

Functions will remain disabled until your cable is properly detected and installed. If Severn FlashApp remains disabled after connecting your cable, there is a problem with detecting the cable; the cable is incorrect; or cable drivers are improperly installed. Consult the instruction pdf file in the FlashApp folder if further troubleshooting is required.

If the bottom left corner shows "OBD2: Not Connected" in red, click this button to refresh COM ports.

To reduce the risk of failure, your car’s battery must be in good condition, fully charged, with a 10+ amp charger connected

Make sure to temporarily disable any background services on your computer that could interrupt the flashing process. This includes virus/malware scanners, screen savers, or sleep settings. Some customers have noticed that these have interfered and caused their flash to end prematurely.

Click "Download" to begin the ECU backup/read process. Note the status bar at the bottom of the screen.

After the download finishes, FlashApp will ask if you want to save this file on your computer. After clicking Yes, another dialog box will appear as shown below which will allow you to specify several things about the tune. After selecting the appropriate choices, click OK to save the tune.
