New Hemi Security

Ok, So in another thread we were talkign about wiring and splicing and all that good stuff for a 5.7 swap. OMG

So I am looking at buying a computer from a junkyard or online. Maybe getting it flashed at hotwireauto or another spot.

These places can't flash a computer with security...the RFID key.

How do i know what to look for? being a junkyard car or whatever, there is no guarantee that I would be able to find one or even be told truth.

Any suggestions?

FYI, I am aware you can buy a new computer...its to much for me right now.
