    Can't read 1227747 chip in my AutoProm?

    I think the stock 1227747 chips are 2732a but I can not get my AutoProm to read one. Then tried all the other chip settings and they verify but when I open them in TunerPro it's all o data?

    What am I doing wrong?

    Offsets?

    Offsets change automatically when you choose to read a chip in AutoProm. But that is what I think I am doing wrong because another chip from a 427 OD did not read correctly either? I think I got to compliant with burning bins to 27s512 chips...

    Although the AutoProm does change offsets when you choose a chip to read, they were wrong. I then choose the 2732A chip and entered

    Chip start - end: 000000 -> 000FFF
    Buffer start - end: 000000 -> 000FFF

    And it worked.

    These were not the offsets that AutoProm changed to to read the chip?
