C2T WUR with two bimetallics and control pressure

Gents, I'm trying to get my control pressure to behave. It starts up at 1.7b, which is fine, but it stays there no matter how hot the car gets. And the wideband (and fuel gauge) reflect this.
I've adjusted the upper bimetallic post up and down, and I have it topped out now that it's no longer affecting control pressure. I have 12v from the WUR heater plug, and I have ~40ohms on both heater elements, so I suspect they are both working.
I cannot find any info here about this mysterious second bimetallic. I dialoged a bit with Rarly, but he isn't familiar with the two-strip WUR either. My next step is to begin adjusting the bottom strip in the same fashion as the standard upper one; anybody disagree?
Thanks for your input!
