I am hoping that Matt has a quick fix so I can avoid rewiring. In the interim, I basically run Logworks in parallel so that I can see both WBO2s and verify that they are close, and then switch over to Nistune and log the left one. It is a little bit of a pain but it is workable - I have dealt with much larger PITA's with the Z actually (at least I can do this part sitting down - lol)
