Default 09 NPP M2W not working.

I have a 09 base with the npp exhaust set up. Everything works fine until I plug in the m2w and then it don’t work. I have checked vacuum power to vacuum switch and what not. I just can’t get it to work when installed. I have even tried 2 different m2w switches. And ran a ground straight to the battery. Does anyone have any idea why it may not be working as soon as I plug it in?

Not sure I understand the issue, when you press one button on the remote its the same as pulling the fuse, it defaults to open valves 100% of the time. Pressing the other button leaves it in computer controlled mode when you hit around 3500 RPM it opens the valves till the rpm drops. Then they are closed. When you said its not working what exactly do you mean?

the system works perfect on the car.(without m2w) Everything is tested and working. It’s like it won’t accept the m2w. As soon as you install the m2w the valves won’t close at all. (Like when the fuse is pulled). It’s the 3rd m2w I have tried so I kinda doubt it’s that. I have tried different grounds, I even ran one straight to the battery post for testing purposes. I just didn’t know if anyone had these issues.

Is your M2W controller the type with a fuse tap that you put your original fuse into? If so and if you didn't it wouldn't work. Mine grounds to a screw on the factory bose amp
