Does anyone have a Definitive answer if Flashcal will let you lower the tire pressure, without any issues, such as lights or alarms. Half the reviews say yes no problem, and the others say it doesn't work. How they can be so many different reviews . I'd rather just lower the pressure than disable the whole thing. Going on a 2013 Jku. any advice would help.

 

Superchips changed the way they handle it.

Used to be you could lower the pressure - or - set to offroad mode and disable the system. For whatever reason, they no longer allow you to lower the pressure.

I spent a few weeks working with their clueless techs trying to figure out how to get mine shut off. Wish I had just gone with a procal.

 

I just got mine a month ago and all I had to do is download the off road tire pressure mode from SuperChips. You can't adjust the settings it's just on or off.

 

When you say turn it off, does this mean no lights on dash or alarms.

 

Correct. The TPMS system is effectively shut off. No lights, no chimes, nothing, regardless of how much, or how little, pressure is in the tires.

TPMS Offroad is a seperate function that needs to be downloaded. Once on your flashcal, the wording may be a bit confusing. You will Enable the tpms offroad function to disable the system. Then Disable tpms offroad to re-enable the lights/chimes.

 

I just bought still haven't opened it, disable is not ideal but doable. I was thinking of returning it for a Procal, but I think this will work. thanks
