    made my own disassembly and complete XDF.... calibration section is 100% decoded, i did very little commenting of the algorithm though, since i already understood how it worked based off of $A1.

    XDF was made with TunerPro V5, so it will not work correctly with V4.

    EDIT: $88 was also used on the 7727s in the W-bodies.

    fixed another small error in the XDF, the IAC step scalar for P/N had it's address in the middle of a table for some reason.... corrected now.
