0xF2 could be Song Position Pointer, but clearly that data is looking a little odd. Is your DX7 E!-upgraded or similar? I wonder if it's sending some (corrupt) sequencer-related info.

No, it's absolutely vanilla, no expansion boards, all chips are original. So the Song Pointer doesn't make any sense. The superfluous F2 is only in a part of the sysex, in other places it's B0 and other dirt as well, nothing that makes sense here.
