I know $42 has a scaler for EGR on/off, iirc $88 uses a modifier table, and $24 as well. There isnt any modifier I could find for spark or fuel in the S_AUJP xdf, and im not capable of finding something like that in the disassembly yet. I will make a note of the items to be logged and will record while on my way home from work. Even $24 has more modifiers that could be used. When I get home ill also look thru other $8D masks to see if there is more available items, if so ill put them in the S_AUJP xdf as long as the locations match up.
