The Cobb site is also very clear on the fact that you can resell an uninstalled Accessport.
Yep, I just did this. I totaled my 135i and bought at Z435i. I unmarried my Cobb from my 135i and installed it on my Z4. My DME was not a recognized ROM with Cobb so they had to update my DME version but once that was done it worked great. I have not had any problems with the DCT and I have been running the Stage 2 tune.

I used ESS in the past on a M3 and I do believe that they know the BMW product very well. However, their product is very inferior to the Accessport and I would never buy something that I could not resale.

Also, you have to pay for every tune that ESS has and you can use any of Cobb's tune for free.
