If the ECU ignition circuit is damaged then you will not be able to upload a calibration. I do not believe it is the USB driver because KManager can retrieve the serial number etc from the KPro.

So today we finished my friends k swap in his em1. Used my ecu and it worked? However it didn't work in my friends preface ek the other day which is strange. Only difference between the 2 is obd2a or b.

As soon as we switched ignition on in my friends car the laptop picked up the ecu as normal, which proves my ecu isn't getting an ignition signal in my car
