Can't log my AFR's
 

So I'm trying to log through rear o2 and my AEM gauge is reading between 250 and 180? The formula I'm using is 2*(5x/1024) + 10. I tried changing it up and it didn't help at all. I'm using Golden's XML and the address is already in there for the rear O2 (238086B9). I learned from Golden that the standalone address is 8086B9, although I don't know how to use it to my advantage. My ROM number is 59590004. Here's what my setup looks like:

You guys think you can help me out here, I'm hella confused.

I haven't been able to log at all! Same rom number as yours. Did you end up figuring it out?
