via Quick Setup in step 1.
3. Connect your FlashScan V2 device to your vehicle.
4. Turn the vehicle ignition to the On position, (not the Accessory position.
Vehicle must not be cranked/running when flashing).
5. Navigate to the F2 Tune Tool -> F1 Tuning and select F3 Program Full menu
option.
6. Using the arrow keys, navigate to the correct tune file and select OK.
7. If the controller has not been licensed by the selected FlashScan V2
previously, you will be presented with the License this controller now?
message. Select Yes to license the controller or No to exit.
8. Select Yes to confirm licensing the controller and commence the flash, or No to
exit.
9. When the flash process is complete the Reset Controller notification will be
shown. When prompted perform the following actions:
a. Turn the vehicle ignition Off.
