4)ABS cal.
5) Speedo cal.
6) VIN cal.
7) Trans cal.

I'll have to remember that for future calibration.

Those particular calibration segments are unique to 1996 and 1997 Black Box Vortec PCMs. The 1998 (the one in this thread) to 2000 Black Box Vortec PCMs have different calibration segments.

Just an FYI ...

yes thanks for the FYI, I was referencing a 97 calibration.

98 is
1) The O/S cal.
2)Engine cal.
3) Fuel cal.
4) System
5) Speedo cal.
6) VIN cal.
7) Trans cal.

So the common segment is still the trans segment. Just wonder why all of his emissions flags were wrong when performing a trans segment swap, unless tehre was more thn justthe Trans segment being swapped.

Hmm.

The only segment that I actively and knowingly swapped was that of the transmission per below.

File, Load Alternate for Comparison.

Edit, Copy entire Segment, choose Transmission, Yes, OK. Save file with new name.

Flash into your truck.
