Once your files have been uploaded to the cloud by your tuner and you are ready to program your vehicle open ECU Connect, plug the interface in and go to “My Car -> Program ECU”. And select the ECU you wish to program. Then choose the Flash File you wish to program and the EVI-BT communication test will be available
Before you can program the vehicle the first time the Bluetooth communication between the phone and the EVI must be tested. Simply press “START” to commence the test and wait until completion.
Once the Communication test is complete you can press the “PROGRAM” button to commence flashing the vehicle, please make sure the conditions for programming are met before you press the program button. An explanation of the programming sequence is shown here Programming an ECU
