Now you can choose what map to flash on your car! (Map availability may differ)
After selecting the map, if you haven’t flashed your vehicle with your phone before, it will run a communication test with the car to ensure data is being transferred correctly.
After the communication test finishes, re select your map to install. DO NOT CLOSE THE APP WHILE IT FLASHES. While it should operate fine in the background while doing other tasks on your phone, the flash doesn’t take that long and closing the app may result in bricking or ruining the ECU.
Once complete, turn the car off for a few seconds then turn the key (or press the start button) so that the car is on but not running, and leave it there for about 5 seconds. Turn the car off and then you should be good to go!
