So I got the box in and all wired up. Was going through the checks to make sure it all works and I got through the first two. When I go to do the two step it won't engage. I'm pretty sure I have found the issue why. When I bring up the interface it's not reading RPMs. Have changed everything like the install instructions said but can't figure it out. Any help would be great. Thanks

So I got ahold of the guys over at N2MB racing that make the box. They said it won't work unless it's tapped into the negative of the fuel injectors.
