The software supports over 80 modules. Version 1.20 specifically refined support for: Simos 18, Bosch EDC17/MED17. Toyota/Lexus/Scion: Generation 1 and 2 ECUs (76F00xx).
The New Trasdata is a more comprehensive ECU programming tool with broader vehicle coverage, supporting reading/writing of entire ECU memory, including flash, EEPROM, and serial EEPROM. In contrast, PCMflash is a more focused, budget‑friendly option primarily used for flashing the main ECU memory for performance tuning. However, users have reported instances where PCMflash successfully wrote to ECUs (e.g., EDC17CV42) that New Trasdata could not identify or write to, due to checksum algorithm issues.
PCMFlash 1.20 typically requires a USB security dongle for software authorization. For vehicle communication, it adheres to the . This standard ensures compatibility with several professional-grade hardware interfaces, such as: Scanmatik 2 Pro Tactrix OpenPort 2.0 DrewTech CarDAQ series Microprocessor Support pcmflash 1.20

While later versions of PCMflash have introduced new features and modules, version 1.20 has become something of a legend in online forums—largely due to its pervasiveness in the clone market. In the original software ecosystem, the number of activated modules is tied directly to a Guardant USB dongle; a version 1.20 key could be purchased with 67 modules enabled, whereas version 1.21 keys typically came with 11 or 14 modules. The New Trasdata is a more comprehensive ECU
