No problem, open up the V7.5 Scan tool and click the green button on the upper left hand side. Select the controller your car uses and then press ok. Now go Bidirectional->Change VIN. Enter the VIN you want and press ok. Should be good to go, I believe you have to turn the ignition off for 15 seconds after a VIN write just like a normal flash.

What effect does the vin have on the software version? I.E if im running an 04 ECU from on a 99 Car? will i get an incompatability???
No not at all, EFILive doesn't use the VIN for any licensing details for starters.
The scantool will negotiate with the ECU what PID's are supported so again the year shown in the VIN doesn't matter.
I no longer monitor the forum, please either post your question or create a support ticket.
No.

All, I am new to this forum as of today. I have a 2009 Sierra 2500HD CCSB LMM. I have acquired a downer PCM from an 08 LMM, Bosche P#12628593, same as my stock 2009 in-use PCM. Can I use EFILIVE V7.5 to read the downer imbedded content (after installing in my truck but not starting), and change the VIN in the downer to match my truck without needing an EFILive license for the downer PCM? Also if I simply power on the truck but don't start the truck will the downer PCM populate any harm to my other modules, TCM, BCM, etc.?
A simple yes or know answer is adequate, unless there are gotcha's or caveats I need to know!
TIA for your assistance.
