No. However, if you have an M7 and never use Eco Mode you won't notice much difference between having the fuse out and having the fuse in with the exhaust set in track mode. As I said in my other post, with an M7 with the Drive Mode set in Tour, Sport or Track and with Engine Sound Management set to Track Mode the only time the valves will close will be when the transmission is in 5th gear with engine rpm below 1500 or less than about 37 mph. In any other gear below 1500 rpm the Exhaust valves are open. That way you can use the features of your car to put the Exhaust in Stealth Mode if you are driving on a highway and want to listen to the radio. My Z's exhaust drowns out the radio when I have the transmission in 7th gear with the cruise set at 80 mph unless I put the exhaust in Tour or Stealth Mode.

As previously said - no.

I use the Range and have the exhaust fuse pulled.

No problems.

The M2W is simply removing/inserting the fuse for you remotely. I push the right visor button and close the NPP valves. I push the left button and open the NPP valves. THe center button opens/closes the garage door.

At least with the M2W, I can be quite when I leave my house at 4 in the morning and not upset neighbors

there are times i feel bad for my neighbors, long tubes, borla atak, and decent cam....

You can do the same as the Mild to Wild with the Engine Management already in the car.

Got it, I misunderstood, I thought you meant that if I pulled the NPP fuse it would give me a code for the AFM. Thanks for the clarification!

The aggressive Cold Start mode that you love so much is the reason for the mean sound on startup that fades away. It is programmed into the ECU. What happens is the ECU pulls timing into the negatives so that the combustion process happens as late as possible and sends more heat out of the exhaust valve to light off the catalytic converters quicker. This is mandatory for all cars by the Government. You just don't hear it as much on regular cars because they are designed to be quiet.

So your valves are not closing after startup, they are staying in whatever mode the car is in. But the timing is being pushed back up into normal values a few seconds after the cold start. Same reason why you don't get a mean startup once the car is already warmed up. Like if you run into the store and come back out in 5 minutes and start the car, you don't get an aggressive startup. It's all based on estimated catalyst temperatures and coolant temps. In some older versions of HPTuners, you can change the cold start mode to either never enable, or to even enable when the car is already warm.

Thank you for that explanation.

Mild to Wild does do something, it gives you the option to turn exhaust quiet or loud at the push of a button

Something that pulling the fuse cant do

Mild to Wild is just a way of "pulling the fuse" and putting it back at the push of a button.

But not as easily or quickly as the M2W allows you to do it. I press one button on my HomeLink to make my system loud, one button to make it quiet. I don't have to go through a series of buttons on the infotainment screen to make the change.

At only $80 it is a no brainer

Dcasole

so I thought that's what I said .......

Dave

Dcasole

That is how I have mine set up , one simple push ...closes it or opens it

Mostly yes, I was only adding the specific part about how it basically just remotely pulls the fuse so that it might be helpful to someone that may not quite understand how it works beyond the pushing of the button.

Excellent writeup! Thank you for explaining it so well!

SpeedyClaxton

pulling the fuse is the easiest way

Leroyt10

This is true.
