There seems to be a lot of confusion here. The v3 you are talking about is only the board revision and therefore has the same potential as the earlier v2.2 board. You also don't have to worry about the old 8x8 map versions because it's a question of only an old software version. You can update it in a minute from the web without a programming device. The real choice is whether you want the MS-I or the MS-II processor. The MS-I has more feathers developped to it and therefore has all the whistles and bells, but it is limited by the older assembler programmed 8-bit processor. MS-II has a much better processor but is only starting it's evolution and therefore doesn't do much more than controlling the injection and ignition, yet.
