    Looking for 7A 2 plug and 4 plug bin files

    Looking for 7A 2 plug and 4 plug bin files. Looking to make workable Hitachi editor with known maps. Probably no one will use it but me lol.

    Here is my one file read from a 4-plug 1990 90q 7A. I'll take aaf v6 stuff too. I have been mapping it out as well.

    I have created a No-COPot Patch. Eliminates the 4th CO wire. Helpful for V6 maf swaps or broken pots. This also creates an open ADC input(more on that later). I know the V6 maf scaling still needs to occur, working on that next.

    Currently driving on "266D_stage2_93oct_co.bin" The stage 2 is built upon what was learned from the 266B 034 RipChip 7A Stage 1 which was very mild.

    CO Pot Disable Patch
    Disables idle lambda trim (pin 4) and suppresses fault 00521 when no CO pot is present. Works for both 266D (4plug) and 266B(2plug). The patch redirects the LDAA instruction that reads the CO pot ADC result to load the baseline channel instead, making the trim delta always zero.

    266D_copot_64k.zip: is a stock tune for 7A maf with the 4th wire disabled. 27c512
    266D_stage2_93oct_co.zip: bit more of an aggressive tune for 7A maf with the 4th wire disabled. 27c512
    266D_stage2_93oct.zip: bit more of an aggressive tune for 7A maf with 4th wire. 27c256
