Aha, I recognize that memory address, I've been looking into this previously.

S10C/FFF815E0, K00G/FFF810B4 - there are 35 pairs of (A, B) floats, stored in the order A1 B1 A2 B2 A3 B3 etc. The FLKC values you see in datalogs derive from the A-side.

Yes, the ECU RAM is kept alive by the battery, which is why pulling the battery or fuse resets the ECU. There's an EEPROM storing VVT learned values, which I want to look into more someday.

(Also: S10C/FFF816F8 is the start of a series of unsigned shorts that is storing what is likely FLKC counters of some sort. That's where my research left off, so I don't have any details for this yet.)
