The standout feature of the version 1.20 dongle is its activation of within the software. A typical module list for a 1.20 dongle includes licenses for modules 1 through 38, 40, 42, 43, 45-48, 50, 52-74, but notably, modules 39, 41, 49, and 51 are usually not activated .
The software supports a wide range of operations across over and 20+ vehicle brands: PCMflash - ECUTools pcmflash 1.20
PCMFlash 1.20 is a Windows-based tool used for flashing ECU (engine control unit) and immobilizer firmware, reading/writing EEPROM and flash memory, and performing diagnostic functions on various vehicle makes. This paper summarizes its features, typical workflows, supported hardware interfaces, security and legal considerations, common use cases, and practical recommendations for safe operation.
In practice, the tool is reported to handle common tasks flawlessly. For example, users have successfully read and written to various ECUs, including the DQ250 DSG transmission and the EDC17C46 engine control unit. A user on a tuning forum also detailed a successful test where they used PCMflash Module #29 via the OBD2 port to read an entire EEC-V PCM, with the software confirming that all checksums were correct.
Version 1.20 maintains support for a wide variety of controllers found in global automotive markets, including:
"pcmflash 1.20" reads like a compact artifact of focused engineering: a point release that carries both fixes and the quiet ambition of small tools that punch above their weight. The version number suggests maturity—past the rough edges of initial launches, now delivering incremental improvements that matter to users who rely on predictable, low-friction workflows. : In the aftermarket, version 1
Previous versions struggled with locked bootloaders found in newer Bosch (MD1, MG1) and Continental ECUs. PCMflash 1.20 introduced enhanced bypass protocols that allow tuners to read these units via BDM, JTAG, or even OBD2 without physical disassembly in many cases.
