TMax Tuner Software is designed for Windows-based systems and requires a computer running Microsoft® Windows 2000™, XP™, Vista™, 7, 8, 10, or 11. An Intel-based processor is required, as the software is not compatible with ARM-based systems. For users operating on Windows 10 or 11 in S Mode, S Mode must be disabled prior to installation.
A minimum of 140 MB of available hard drive space is required to install and run the software. Please note that TMax Tuner Software is not compatible with macOS, Linux, or any non-Windows operating systems.
