Just read out the E84 program/data.

ZFADINFO*Z5YA6800_8HPXY_BMW_K680A*BMW*8HPXY*E26_1* ITCU2_3_X_2048*20110523_075319_FRDC12299*BMW_8HPXY _AT50014_Z5YA6800_K680A

Seems like this data is identified 8HPXY_AT50014_Z5YA6800_K680A. The fields don't line up with either the E70 data, nor the F25(?) damos. Nice to have an extra data point though.

As for the EEPROM read, I've just realised something. Why the heck is most of the file filled with "MMSBLANK"? Surely this isn't actually stored in the EEPROM? Maybe the bench tool is substituting it in for some reason.

I think the Yanhua tool reads out the "full" dump from the transmission, then sends it home to be decoded into map and EEPROM reads on their server.

The "full" dump ends at 0x23000F, which doesn't seem to line up with any of the address ranges in the SH7254R manual. I couldn't find a datasheet/manual for the SH72519 or SH72549 anywhere, unfortunately.
