I have a second Steelmate TPMS unit on my old 78 GL1000 and so I swapped the rear sensors and it made no difference in time to update, although both units seem to work quicker on the Old Wing then on the F6B.

Now it could be the F6B has more electronics on it or it has to do with the position of the receiver. On my Old Wing the receiver is mounted up on the Handlebars but on the F6B the receiver is mounted down in the tunnel along side where the Right Handlebar mounts.
I understand what you have already done and are about through with this. But ---- swapping the front and rear without reprogramming would be an easy test. And there would be no other variables to deal with. What if both of the sensors you put on the rear are not exactly the same/as good as on the front? If you would humor me, I'd like to know the outcome.
