Hi,
I have 2004 Duramax LB7 with a E54 ECM that was locked from a tuner. I used the EFI V8 with the key reset funktion and it worked. But I am not able to reflash the ECM with a VIN and Serial number?? When I load the file and take a Full flash, it says that everything is OK, but when I reset the ECM the VIN and Serial is reading 00000000000. Is it any way to fix this?
I appreciate any answers here.
Thank's
Fredrik B
