What you want to do is technically impossible. By technically, I mean the system was designed to marry the DAS security system after 40 key strokes and can never be moved to another chassis number. The variant data that can be loaded into a new controller to work in your car is quite a different concept than the security issue you are facing.
If you wish to use that controller email me and I'll tell you what is necessary.
