Background
In the Model S and X, depending on the age, Tesla uses one of three different MCUs (Main Computer Unit). This test checks which hardware is in your vehicle when run from the vehicle’s browser. (Feb-2024 update)

Notes
- Platform indicates the MCU processor, MCU-1 uses the Nvidia Tegra 3 (arm) processor, the MCU-2 uses the Intel Atom E8000 series CPU, and MCU-Z uses the AMD Navi 23 CPU.
- UserAgent relates to the hardware and browser software in use. Expected values were collected in 2014, 2018 and 2022
- This utility was optimized for the S/X and may produce wrong results for other vehicles such as the 3 and Y.

- Faster CPU
- WiFi Support for the 5 GHz band
- External Bluetooth Antenna
What’s New in MCUZ
- Even faster CPU and GPU
- Support of up to 3 displays
- Support of higher resolution displays
