Got the switch wired in and followed the "efi installing the dsp5 custom operating system" instructions for converting the tune from 1 to 5
Going to load the tune on the truck, the efi instructions say perform full reflash by clicking the program button on the right (of the 2)
Only 'program pcm with currently loaded calibration' option is available. The 'program pcm with operating sysytem + calibration' isn't highlighted for me to click.
I downloaded the latest version of efi with in the last week or so.
What rookie mistake am I making?
