Piasini Engineering Serial Suite v4.3 is a professional ECU programming tool designed for chip tuning professionals. This is a "Master" version, which means it reads and writes open (unencrypted) files, giving the tuner complete control to modify the data without restrictions. The Piasini programmer is particularly renowned for its excellent and stable support for Japanese vehicle ECUs, especially those manufactured by Denso and Mitsubishi, which can be challenging for other tools.



Key Features:

• Master Version: Full access to unencrypted ECU files. You are not locked to any file provider, giving you the freedom to create your own tuning solutions.
• Strong Japanese ECU Support: Considered one of the best tools for brands like Toyota, Lexus, Honda, Subaru, Mazda, and Suzuki, with extensive support for Denso and Mitsubishi control units.
• Serial Programming Focus: Specializes in serial communication, allowing for reading and writing of the ECU via the diagnostic port (OBD) or direct connection on the bench, often without requiring complex boot mode procedures.
• Comprehensive Car List: The package includes a detailed CARLIST.xlsx spreadsheet, allowing you to quickly check the full list of supported vehicles and ECUs.
• Detailed Documentation: Comes with a wealth of support information, including "NEW" and "OLD DOCUMENTS" folders, pinout text files, and images of the necessary cables.
