The gin file extension is associated with GWv4, calibration software for Microsoft Windows developed by GEMS (General Engine Management Systems).
A gin file contains data for an engine control unit. GWv4 uses this data when working with the settings and calibration of a GEMS engine management system.
Open a gin file with GWv4 on Microsoft Windows. Use the file-opening or import function in GWv4 to load the file for the associated GEMS engine control unit.
A gin file is not normally converted to another format. It contains engine control unit data for use by GWv4, so conversion to a general-purpose format would not preserve its calibration function.
Keep the original file and use GWv4's own saving or export functions if a different file representation is required.
