yep, newbie here, sorry for that...
after browsing forum threads, came up empty so just started using efilive flash scan (scan only) v2. Updated efilive to most current version, updated boot block and firmware (as per instruction) to most current aswell. I bought this only to change the vin number (thus why scan only version) for my swaped LS1 5 series BWM and seems either Im missing something or I did not click the correct thing. From the beggining in F2 - I read the PCM successfully, F3 - shows all the details and in F4 - I click the ... next to the vin number (which when mouse over it states "change vin" i get this awesome error - see attached. Still searching now for a solution online. Thanks
