I have a V2 and all software/firmware is up to date. My e38 ECM has just been programmed and returned to me. Now I need to do some slight tweaks to it. I'm able to read the calibration file just fine. The file is not locked or protected.
The problem though is that the ecm serial number is blank. EFI Live tells me that I need to do a full reflash so it can assign a serial number. So I try - and it won't flash because the serial number is blank! I verified that it was programmed this way because the person who programmed it also sent me a copy of the calibration file and it shows the serial number to be blank. The only thing I know about the original programming is it was done using a V2 & a stream license.
So how do I flash a new serial number onto the ecm if EFI Live wants a serial # first? Here's a copy of the output I get when I try to flash if it helps:
It tells me the ecm is ready for reflashing? And then the ecm is in an unknown state? The ecm originally came from a 2008 Silverado donor vehicle with a 5.3 that I had. It was then programmed as a 2009 so that it would work with a T43 trans controller in my 6L80e out of a 2009 Escalade.
