Yes. Purchased mine Sep 2024--I guess considered Version 1 which has old soft/firmware. From the MAD installation manual for V1:
Top Button (Red): Fully opens the exhaust valves for a 100% unrestricted flow and maximum sound.
Middle Button: Opens the exhaust valves to 50%, offering a controlled and refined exhaust sound, reducing drone or rasp.
Bottom Button: Activates the OEM mode, restoring the factory exhaust settings for balanced performance and noise regulation.
Memory Mode: Always active, ensuring the system retains your last selected mode, even after the vehicle has been turned off and restarted.
If you've browsed MAD's site, than you know "new" version has a few more modes: "
New User-Selectable Modes: Choose between 0% (fully closed), 25%, 50%, or 75% valve positions by holding the middle button for 3–5 seconds. Save your preference by pressing any other button."
If you somehow end up with V1, not sure you can upgrade to V2 soft/firmware.
