Summary of change:
ECU - 14951 - M52 PNP Order id 13910 Repair - ASAP Delivered to VEMS - 11th Dec 2017 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? --------- '''ECU sn 19860''' I need help to diagnose this ECU so I can actually use it It hasn´t left my bench, I added second serial and 5v to second serial which works. What I am getting is the NFET board output are always on (EC10/pin1-4) * See the '''paper''' included with the ECU (save a photo or scan for future reference) * '''if inverted''', than activation will turn them off. Extra outputs can possibly be controlled from: * p259 channels (activate all, 1 by 1) * s259 ch 1-2 (internal signal), in VemsTune: "Extra output 5/6" * See GenBoard/Manual/DigitalOut/Table * VT: see VemsTuneVersion and validate ** if in doubt, publish .vemscfg There are 10 wires total for this small narrow board Measuring results with all P259 channels off (unused) Thick RED - 12v Thick Brown - 0V 4 Thin Wires - all 12V 4 Thick wires - all pull to ground enough to activate my test LED Gunni
