More about PCMFlash
What is PCMFlash — and what is it used for
PCMFlash is one of the most widely used ECU and TCU reprogramming software by professional technicians worldwide. It operates with a USB dongle with a unique code — each dongle is linked to specific licenses, with no monthly fees or annual renewals. Once activated, the license is yours forever.
With PCMFlash, technicians read and write ECU and TCU data directly via OBD or with a direct connection to the board, perform automatic checksum correction, clone modules, and perform remapping. It is compatible with any J2534 or RP1210 interface — such as Scanmatik 2 PRO — and is regularly updated with new modules and vehicles.
Each dongle has a unique code. If the dongle is lost or damaged, the associated licenses cannot be recovered. Handle with care.
