The Z4M is a small market. We have a different and supposedly better ECU than the M3, although we still use the M3's slow communication bus so its potential isn't realized. For reference it took an hour to flash the AA tune, which was only a few megabytes if I remember correctly.

I thought I remembered Hammond commenting during his Top Gear review that the Z4M DOES have the same trans as the M3? I could be mistaken though.
