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_stage2_93oct_co.zip: bit more of an aggressive tune for 7A maf with the 4th wire disabled. 27c512
