    Default Unable to Open any E78 ctz file

    chase 2014e78 stock ecm.ctz



    I've done the latest V7.5, V8, and firmware updates. I can read/write the e78 ECM all day long. I'm just unable to do anything with any e78 ctz files in V7.5 (180), as I get a warning message related to GM Cal reflashed, COS loading without initial ctz file, or attempting to load a COS.

    If I open in 7.5 there are no parameters to inspect and only the VIN decoder/history/display box is able to scroll through tabs.

    Any suggestions? LS1A/B, E38, E40 ecm's all work without issue.
