Anyone had any luck with one of these tools for programming TPMS sensors? Apparently it is also known as DBL4, Bartec Wheelrite Tech 300 Plus, or Napa 92-1525. I got a hold of one and am trying to use it to program the Schrader 33500 EZ-sensors but it says I need a firmware update. Schrader doesn't seem to share any of these files, any suggestions?
