Just had the MAD valve controller installed. And there is zero difference between 50% and 100% open. It literally sounds exactly the same. Is it possible I got a defective unit?

100% open sounds excellent, especially with the MAD non res midpipe installed.

Something else I noticed is, at 100% open mode, when coming to a stop and the rpms drop down to idle, it almost sounds like the unit closes the valves until you hit the gas, then opens them back up.

Anyone having this experience thus far?

I highly doubt it's defective since it's working on opening and closing the valves.

if you can see the valves, i recommend checking it for movement when you press the button. not that 50% is actually 25% of movement

if you cannot see the valves , put the car on the lift and check if the spring is moving when you are pressing the button

Hi,

Can you verify the valve is moving when the 50% button is clicked? Depending on our exhaust setup and amount of flow through the system (idle for example) a 50% closed valve may not be enough to force the air the through the muffler

When in 100% open mode the valve will not move from that position.

I will check this weekend. Im running a stock exhaust with your MAD non res midpipe.

But if there isnt enough flow then I would expect the 50% to sound similar to the stock setup. Not the 100% open. Ill check and see though with a flashlight. Went under load they sound the same from inside the cabin.

You should be able to hear the actuator moving when the engine is off .

Update: We’ve recently released our V2 controller software with an exciting new feature! The middle button, which was previously locked to 50% mode, is now user-selectable 0%,25%,50% and 75%.

The main goal was to try and add a fully closed exhaust position to one of the dedicated buttons since we’re limited to three buttons total.

One of the most common questions we received was why the exhaust couldn’t be closed while in M mode. Previously, the OEM button kept the valve open in M mode, which didn’t give users full control.

Why not just add a fourth button like others have done? The answer lies in Homelink compatibility. Homelink systems only support three buttons, and now you have complete valve control with Homelink, eliminating the need to rely on the remote. This simplifies operation while still offering the functionality users were asking for.

Here’s how it works:

-Hold the middle button for 3–5 seconds to enter the selection mode.

-Choose and lock in your desired valve position: 0% (fully closed), 25%, 50%, or 75%.

-Once you’ve selected your preferred setting, press any other button to save it.

This new functionality provides even more customization, allowing you to tailor the system to your driving preferences effortlessly. Let us know what you think!

Important Note: Unfortunately, this update is available only for V2 boxes shipped on or after 11/22/24. We currently have no way to update boxes sold prior to this date.

Good news! Mine shipped 11/27, is there any marking on the box to confirm I have v2?

Negative on my 2025. No valve movement without the engine running.

No markings but if it was shipped on that date you have a v2 .

Just installed my valve controller Friday from XPH and I think it’s V1 because it doesn’t open the valves when off. Easy install!

If it was shipped after 11/22 it's v2

Hold the middle button for 3-5 seconds when the car is on and try and clycle through the options. Click any other button to save

Oh will try. Yes it was shipped after 11/22. Also just received your resonated mid pipe! Will post videos Wednesday when I install! Quality looks so goood.

Having the same issue… nothing happens when middle button is clicked.

Are you looking in the back of the exhaust to see if the flap is moving?

50% wont make a huge difference at idle because there isn't enough flow create the back pressure to push it through the muffler instead of just out the straight pipe.

Ah I see what you mean now. Do you mind further explaining how that middle button works? I hold down the button and the valve opens and I keep holding and it closes…

Of course!

Here's how our updated V2 software enhances the controller functionality: Thanks to GolfCoyote for the idea. https://g80.bimmerpost.com/forums/sh...2113057&page=2

Previously, the V1 software locked the middle button to 50% mode. With the V2 update, we’ve made the middle button fully user-selectable, allowing you to set it to your preferred valve position: 0%, 25%, 50%, or 75%.

Rather than adding a fourth button like some other systems, we focused on maximizing the use of the existing 3-button setup to maintain seamless integration with HomeLink. Here's how you can customize it:

1.Hold the middle button for 3–5 seconds to enter selection mode.

2.Click the middle button to cycle through the options (0%, 25%, 50%, 75%).

3.Once you’ve found your desired setting, press the top or bottom button to lock it in.

After saving, the middle button will always activate your selected valve position until you change it again. Simple, intuitive, and giving you full control without needing to leave your HomeLink setup! Let us know if you have any other questions!

I recently performed this test, and directly checking the valve position is not easy since the difference between 25% and 50% isn't very noticeable. The best approach is to place the car on a lift and check the valve spring, you can easily see it move with each button press.

It's also important to note that 100% open, is actually at the 50% position, where airflow is maximized. 50% is essentially 25%, and 25% is 12.5%.

From the description it is not 100% clear if Memory Function can be disabled? Always start in OEM mode. Just don't want valves to be open on cold starts, and don't want to always remember to close them manually before I start.

you can set the MAD controller to default at valves closed

Memory mode is always active as of right now. You would need to set it to 0% or oem mode.

Ah it's a shame. Any plans on adding this feature? I think SST controller has two modes, but I like everything else about yours more. I am sure that there are many people who would like to have cold starts as quiet as possible, but don't want the additional headache of pressing a button before you start.

Yes, it's definitely something we plan to add in the future. For now, you can press it anytime before or after your next start, but I completely understand your rather a set it and forget version.
