If you took that nut off I don't know how to help. But I can tell you between talking to PADDO and getting a new sensor yesterday the factory/default setting of the sensor is the top of the heim joint is all the way at the bottom of the slot and there should be about 8 threads visible on either side of the middle nut on the threaded rod. It out my height right where it is supposed to be +0.1 and -0.2 in the software. 19.8" on the DS and 20" on the PS. I made the mistake of messing with the TBs first. So now my pressures are low and I'll have to correct that.
