Haven't used the thundermax but had the same thing with my PCV when I added autotune. I went back and reseated all the wires and it started working. I also read one post where someone used the wrong power plug. I used the one under the left side cover on my 08.

Mine used to do this too. Well, it SAID it didn't see the sensors but it was seeing them, because I could see the adjustments it had made. Had the guys from Zippers look at it out in Sturgis, their computer didn't give them the same error message. We determined that it was my Radio Shack UBS/Serial cable.
