ST10F275, MPC562, SH72549, and TC1766/TC1738, supporting read/write and checksums.
A post from PCMflash’s official Facebook page, titled “ PCMflash Update: New Modules and Additions! ”, confirms that alongside protocol updates, three new modules were added, including:
Some of the modules that are often activated in full packs include:
A: While not officially tested by the developer, many users report that it runs on Windows 11 with the same compatibility settings as Windows 10. For critical workshop use, a dedicated Windows 10 system remains the safest choice. Pcmflash 1.21
: Programming by removing the ECU but without opening its cover. : Requires disassembling the ECU for direct board access. High Performance Academy 4. Supported Manufacturers
Once your "tuned" file is ready, select in Pcmflash. The software will check the checksums and then proceed to upload the new data to the ECU. Why Choose Pcmflash Over Competitors?
A: Pcmtuner is essentially a rebranded clone of the Scanmatik 2 hardware, often sold with a cracked version of Pcmflash 1.20. True Pcmflash 1.21 offers enhanced stability and security updates that clones may not fully replicate. For critical workshop use, a dedicated Windows 10
: Switched virtual reading functions to a dedicated server for modules 48, 50, 57, 58, and 65. Module 53 Update : Added support for JLR SID208 and PSA EDC17C60/MED17.4.4. Chiptuningshop 3. Hardware and Interface Requirements
It should be noted that, despite the version number change, the core protocols and modules between v1.20 and v1.21 are generally understood to be the same. One online discussion states that "the protocol and modules are the same for both" and that having v1.21 doesn't necessarily provide an advantage in terms of basic functionality. Nevertheless, v1.21 is a stable and widely used reference point in the tuning community.

Reliable reading and writing with built-in checksum checks minimize the risk of bricking an ECU.
PCMFlash 1.21 is a software tool used for flashing and reprogramming Powertrain Control Modules (PCMs) in modern vehicles. Developed by a team of expert engineers, this software enables technicians to quickly and accurately diagnose and repair a wide range of vehicle systems, including engine control units, transmission control modules, and more.
Pcmflash is a Windows-based diagnostic and programming application designed for reading, writing, and recovering firmware (often called "calibration" or "binary" files) on various automotive ECUs. Version 1.21 is a specific release from the software's history, typically used with compatible hardware interfaces (like original or clone Kess v2, Ktag, or specific J2534 pass-thru devices).
