No feedback as of yet. Customer getting frustrated with repair time.
Issue with the ECU from the first time the customer plugged it into his car. Main relay buzzing.
Please provide feedback to the status of the repair / alterations to the ECU so that the main relay stops buzzing.
Update and further issue with this ECU.
currently on my bench with customers actual engine loom there look to be no issues when its directly connected to the battery. However as described in email conversation the main relay and fuel pump relay don´t work. With his stock BMW ECU they do and the car drives normally. Any suggestions to potential reasons?
