PCM Flash is an integrated software package that works via the OBD-II diagnostic port or direct bench/boot connections to read and write flash memory on automotive computers. Unlike universal tools, PCM Flash relies on a modular system. Users activate individual software "modules" depending on the specific vehicle brands and engine types they intend to service.
