One nice thing I've been starting to like about the AP is that you can switch thru maps easily. Since E85 is FINALLY starting to show up around here you could have a e85 map and a pump map. But to run the E85 you'll need to upgrade your fuel system yada yada. You can do all this with opensource too, just need to keep a laptop on you. There's a few great threads on here and NASIOC that go over the differences.
