Been using Doran TPMS for years; one of the most important pieces safety gear I own. Batteries have died (get 3 years) but that is the only issue I have had.

Re: My bizarre & seemingly unsolvable cruise control issues...hoping for new ideas.
I would look around at anything disturbed while installing Look for pi that did’t lock into housing
Try cruising @ 4k rpm the bike settles right in then every once in a while run it up around 5-6K at least on hard acceleration. You'll still get 42-45mph on average.
