How to identify your Delco E39A3 file

Read the hardware number (HW) and software number (SW) from your ECU with your reading tool, or from the ECU label for the hardware number. Open the vehicle model above, then match HW and SW with the file you need; when several files share the same SW, compare the full calibration string as well. A matching vehicle description alone does not guarantee compatibility: the identifiers decide.

Every file is delivered as an unmodified .bin, exactly as read from the control unit; file size and memory layout can vary with the reading method of the source.
