It can be used on MS1 as there is currently no features and support for many of the "extra" versionsfor MS2 yet. MS2 does not support the 420 crank decoder, no much of the other wheel decoder and other neat features that are in the MS1 extra code. MS1 board version does not matter. They are still doing more work on this hi resolution code, so just keep in mind its still a work in progress, but something to try out and play with.
