Are you looking for a calibration code for Super Chip or whatever?? The tear code so I'm told it's called is located on the PCM itself and the "A" pillar passenger door. Mine had fallin off ,but found one on the PCM. IE "KCA3" 98 Duratec built 7/97.
With an OBD II youcan request the info well at least on 1999+. VIN CIN CVN. I'm using Alex Peper's software on an old laptop. I can not read mine, evidently something changed, since I'm assuming Ford's Star tester could???? Diodeboy proablely can enlighten us????
