The Basics
ECU Connect is the free companion app to the EcuTek Bluetooth Vehicle Interface (EVI-BT). The device connects to the OBD vehicle diagnostic socket of all vehicles supported by EcuTek's ProECU tuning product (a list of supported models can be found here) to allow communication between the engine management ECU and your iPhone, iPad or Android device.

After selecting My Vehicle and choosing your vehicle interface, select Program ECU at the very bottom.
Next, select Redeem Product Code to use the COBB Supplied product code card.
Next, you can either scan the QR code with your phone, or if your phone isn’t equipped, you can enter the code manually.
After doing that it will show up with the car's VIN, input your car's make and model (this can help with future troubleshooting), then select Get Files and the system will download any available maps for your car. (It will automatically do this in the future once the code has been redeemed.
Programming Your ECU (Initial Install or Changing the Map)
Now go back to the main vehicle menu and select Program ECU again.
Select Engine
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!

CARB Sticker (Where Applicable)
Apply the supplied CARB sticker to a visible area, either the radiator core support or underside of the hood to designate the presence of a modification which is CARB exempt.

Failed Programming
If for some reason the programming process fails, it will first come up with an error message. Make sure to write down/screenshot the error message. If you know the reason it failed and the app and Interface are still powered, you may be able to simply press the program button again. If this option doesn’t work or isn’t available exit the app, unplug your EVI-BT, key off the car, then reconnect the EVI-BT again and restart the programming process.
