nope they only read paramiters and codes etc. You will need a chip or flash programmer from the tuning companies:Quick question. Will this device and software, program devices? Can I use it to adjust and reprogram PCM, or GEM? Like using the VCM2 device from Mazda, rotunda, ford.
typical flash programmers-not usually recommended for 7.3l:
edge, superchips, bullydog, diablo sport, banks, SCTFlash
php hydra, dp-tuner, ts 6 pos chip, bullydog, edge revolver, banks
chips allow on the fly changes to the pcm program while flash programmers download your ecm onto the programmer and upload new files to your ecm so it takes a while to change tunes. hence why most go to the chips. mainly hydra and dp-tuner now a days.
