Do you think it would be possible to buy 1 AP and use it on a 04 and a 06 just upload diffferent maps when using it? they are both auto so I thought that it would work.

Nope...

Cobb put in a program which you have to "marry" the ECU to the AP. This prevents you from buying the AP, setting all your friends up with maps, and they lose business.

The 06 has the immobilizer and the 04 doesn't; that alone makes for a significant enough change in ECU programming to prevent you from using the AP on both cars.

I had to wait a little longer than most 06 Sub owners for the 06 FXT Ap to be released. If it was the same, then they would have been selling it right away. IIRC, Subaru changed something in the computers for 06 for more processing power - whatever that really means.
