TIA_MES_byte_DPRAM_F690

VLS_DOWN_1_BAS_word_DPRAM_FA94 ;?
VLS_DOWN_2_BAS_word_DPRAM_FA96 ;?
VLS_UP_1_BAS_word_DPRAM_FA98
VLS_UP_2_BAS_word_DPRAM_FA9A
MAF_BAS_word_DPRAM_FA9E
TPS_BAS_word_DPRAM_FAA2
DTP_BAS_word_DPRAM_FAA4
TCO_BAS_word_DPRAM_FAA6

still unknown:
V_IGK_BAS

There are 16 items here. And I'm guessing all 16 analog inputs to the ECU are referenced here. A couple of them are already labeled.
Code:
