I dowloaded the latest version of the EFILive software, and after manually installing the Vortec calibration files into the L31 folder I created, I can finally open some previously "Unrecognised PCM" files. (I have been having a lot of trouble with the older Vortecs, 4.3s & 5.7s).
However when I tried to open a 2.2 liter and a 3.5 liter file, it's still "Unrecognised". Is there something or will there be something soon I can download to make these work? Those engines are supposed to be supported, according to the list. Thanks!
