Ok so im going to trade my 2000 audi a6 2.7t auto for a 2001 audi allroad 2.7t auto.

My question is my car is chipped with the Giac chip and tranny chip. Can i swap these two ecus so i dont have to sell my chip?

Is it worth buying another ecu and swapping the two out and either sell my ecu or trade it?

should i just leave it in there and trade it in since its not worth much or the hassle?

is the tranny chip worth saving? whats the process for that? is that in the ecu or do i have to buy another seperate ecu? are they swappable with the allroad?

thx for the answers in advance!
