hello, i have a c++ software calibration that is no longer supported by the company that developed it in 1998. i need to modify the calibration to run on different parameters as it controls an EV battery charging system and the original battery chemistries are no longer available. the company (GM) says that the source code and documentation was not maintained and therefore unobtainium. Q1: Is there a method whereby a c++ program can be "opened" and the source code and documentation reconstructed in order to properly modify the calibration?, and, if so, would there be specialists in this area that can be suggested/recommended? thx, s10e
