The 1M does have a bespoke tune/ECU-map and high-flow cats in the downpipes. It's probably easier to think of the 1M as a short wheel-based E92 M3 with N54; including the steering rack (but it does not have a "sport" steering map). Sport mode in the 1M forces the wastegates shut, shifts vanos, and gives very sensitive throttle signal. FYI, the fuse panel is also closer to M3 than 135.
Have you tried MDM yet?
