Digging up an old thread!!! For the last few months I have been using the new version of HPTuners---I had the old serial cable version for years. This same old problem started again---the readings on my scanner were way off---columns did not match between what was set in the Editor and what was scanned.
But I found a solution!! After uninstalling and re-installing the program several times---to no avail---I found a way to make it work. I saved all my configs for scanning and tuning on a Flash Drive----not on my laptop---and all my scanning problems are gone. Might be Windows 7---who knows.
