Hi there, I've messed up my own ECU by loading a map from a different model and I didn't pay attention that after writing the fuel pump wasn't working and after turning ignition offand on the car doesn't start. Kess v2 says that ECU couldn't wake up. I've ordered BDM100 and it's on its way. I have done a backup with kess via obd port and the question is can I write that file via BDM ?
I've got the ECU out and connected on the pins but I have the same message ( ECU wake up ).

Thank you for your time in reading this.

No need to write BDM . Can repair by OBD.Look for a BDM read file for your car and write this file by OBD.Car will start 100%.
