If MECH5 was unable to automatically detect a ECU, then you may have the chance to manually select the ECU if there are multiple to choose from in our database.
Please follow the below steps while connected to the vehicle:
Step 1: Click the 'Connect ECU' tab button
Step 2: If there are multiple ECUs available the 'CHOOSE ECU' button will appear.
Step 3: Click the 'CHOOSE ECU' button and select the ECU manually. (If this doesn't find the ECU you are looking for, then it's not in our database currently. In this case, click the closest possible match)
e.g. If the car is a 1.0, the closest match would be the EcoBoost Gas Turbocharged direct injection 1.0L
Step 4: The choose ECU button will change to green, this is to show the ECU has been manually selected.
If there is not a 'CHOOSE ECU' button then multiple ECU's are not available, as all the ECUs are auto-detected. Please try performing a 'Deepscan' if you think any ECUs are missing.
