Has anyone done a motor and ecu swap on a 2012 to a 2014 motor? I'm wondering if I'm going to have issues with the security key when I switch the ecu?

My understanding is most of the various control modules are tied together by VIN. So if you install one with a different VIN from the rest, you will be locked out.

PCM's can be flashed over to a different VIN, but it is usually a high level dealer only scan tool for the most part.

Yea, I've heard that from another buddy, I figure as soon as I receive the ecu I will take it to the dealership to get it flashed with my vin. Do you know what the cost for a flash like that runs?

If I was to speculate, at least whatever their hourly shop rate charge is. I would expect no more than an hour but not 100% certain on that.

There is also a possible chance they may either want or need the old PCM and/or the vehicle in question on the lot.
