Default Nitrous outlet promax

Can anybody give me some help with a promax controller I’ve got it wired but when I try to connect my laptop to it to set it up The lap top can’t connect to it and the display screen won’t communicate with the controller either. Any help would be much appreciated

I had problems too. Had to update firmware because it didn't match software on my laptop(1.09 on laptop 1.08 in controller) when I went to update controller said error & the red led on promax disappeared permenantly. Was on before I tried updating it now cant get led to light up & cant communicate with promax. I did it how the youtube video said to do it

I sent my promax back to N.O.and they said they updated the controller to 1.09 to match my laptop and the display screen. I got it back and the controller still won’t communicate with the laptop or the screen.
I was first told I needed to follow the YouTube video,then my laptop was bad even thou I tried multiple laptops,then it was it got to hot under the hood of my car that hasn’t ran since I started the install, then it was I don’t know how to hook it up.
I’ve pulled the promax out of my car and installed another brand controller in my car with no problems

This sounds like the installation of the firmware was stopped early. It has essentially corrupted the firmware in the box. We can fix it for you, if you want to send it in. Just give us a call.

We had to connect to it, to update it. Have you tried a different computer?

Yes I Tried to comminicate with the promax with three different laptops before I pulled it out. I was told when it was sent back that it had 1.09 installed in it to match my screen but they still won’t communicate with each other either.

When I hooked mine up the software didn't match & had to send in Promax. They said I knocked the software out trying to update. I got it back & it's working fine now! Even bought the touchscreen works really nice!
