    I also wanted to be able to use more of the MAT counts table for better resolution, considering my max IAT temps maybe get to 140*F or 60*C on a hot vegas day. so i was just looking at the $8D hac and at L87FD i can see all the bytes.

    -------------------------------------------------------------
    ; MAT COMP Vs MAT
    ; TABLE is MAT COMP COUNTS
    ;-------------------------------------------------------------
    ; VAL BIN MAT Deg c
    ;----------------------------------
    L87FD: .byte 0x00 ;= 0, 0 -40
    .byte 0x0C ;= 12, 12 -28
    .byte 0x18 ;= 24, 24 -16
    .byte 0x24 ;= 36, 36 - 4
    .byte 0x30 ;= 48, 48 8
    .byte 0x3C ;= 60, 60 20
    .byte 0x48 ;= 72, 72 32
    .byte 0x54 ;= 84, 84 44
    .byte 0x60 ;= 96, 96 56
    .byte 0x6C ;=108, 108 68
    .byte 0x78 ;=120, 120 80
    .byte 0x80 ;=128, 128 92
    .byte 0x80 ;=128, 128 104
    .byte 0x80 ;=128, 128 116
    .byte 0x80 ;=128, 128 128
    .byte 0x80 ;=128, 128 140
    .byte 0x80 ;=128, 128 152
    ;

    Now could i just open up hex editor and change each byte starting at, say, -12 or 0x0c and end at 72 or 0x48? Or would that mess up the checksum? i would change the XDF and ADX to match as well.

    That may confuse the ECM as well? I wouldn't mess with it, just fix the ADX...

    understood. I need to get my feet wet and ive been wanting to change that for awhile now. Ill continue to ask around or until I become too impatient and change it anyway to find out what happens LOL.
