It's a safety item, and I don't believe it can be "turned off". Either add some air to the tires (hoping that they have TPMS in each one), or put a piece of electrical tape over the TPMS light on the instrument panes.
Mine shut off after driving around for 15 20 minutes. You cannot delete it. You just reset what psi you want to run your tires at. I set mine to 28 psi. My TPMS light does not come on unless my tires go below 28. When I air down off road I reset to 15 psi. I hope that helps. Also, did you do the down load and update?

Yeah its a separate download. When you have the flashcal plugged into your laptop and the superchips application open, it will offer you the download. You have to select it... I guess my only advice is mess around with it more.
