FVD Tuning for Porsche Cayenne Turbo Question

[51.50]

I have a chance to buy a used FVD ECU, but I know nothing about it.  Will anyone clue me in to what I am looking at here?

I am aware of what it does, but I am not aware of the compatibility to my vehicle.  These are my questions:

 

Keep in mind this unit is a older unit that plugs into the vehicle permanently, and is not software installed through the OBDII by a flash tool.

 

Are these units married to a single VIN?

Are they plug and play?

Would it have came with a flash tool (cable/scanner) to make adjustments parameters myself?

 

Any other info that can be provided would be greatly appreciated.  Thank you

I think the immobilizer program has to be programmed for the vehicle it goes in unless it was disable which can also be done by the tuning company so it can be swapped to different vehicles. Most companies don't want to defeat it though as they want everyone to purchase a new program through them and if a car gets wrecked then the program usually dies with the car or someone has to pay a dealer or someone with the know how to reprogram it or defeat it so they can use the ECU in their vehicle.
