Of course, the main reason I bought my Tazer JL was to fix the speedo for my larger tires. It works just great for that.
But I also wanted to adjust the TPMS threshold so that I wouldn't get a zillion warnings every time I aired down for the trails. I followed the instructions but the results confused me. I set the threshold to 12 psi and aired down a tire to see what it would do. I get nonsense like this:
That wouldn't be so bad except that it shows me this every time I start the engine. So I emailed customer support at Z Automotive hoping that I had just done something wrong. It's the weekend so I figured I might hear back next week sometime. But I got a response within the hour. Here's what he said:
"FCA set the minimum to 25psi. Likely the minimum allowed by law. I’m trying to force an override but for now the other option is to just turn TPMS off altogether."
I then asked if I would still get the TPMS readouts if I turned it off altogether and he again replied immediately:
"No they’d go away. The tpms pressure adjust is really meant for oversized tires that run lower pressures not for airing down when off roading. They don’t want you to forget to air back up on-road."
So I'm really happy with Z-Automotive's customer support. And pissed at FCA for being such a nanny. But at least I now understand why it's doing what it's doing.
