Can the TMPS psi threshold be changed?

[Ozbronco]

I'm running 315 KO2s on my 4 door Badlands. I'd like to set the cold psi to 32 all around but on a colder morning they may be at 30 when I start out. Not a problem on all but the left rear, which kicks out a low pressure warning. It won't go away once the tire warms up and the psi goes up so I have to pump it up to 36 psi or so to get it to go off.

It seems to trigger at 30 psi so if I could drop it to 26-28 psi that would be good.

Yes with Forscan, see thread Speedo Recalibration

Ok. Thanks. I was hoping there was a setting to change. Seems like that should be built in on an offroad rig.

i completely agree. I don’t own a windows computer which makes Forscan a real pain in the ass.

I agree, throughout my off roading adventures a few days ago I would have to air down then up then down plenty of times and the low tire warning kept popping up on my app as well.

The sooner you get used to FORSCAN the happier you will be... It's not particularly hard to use, a quick tool for making tons of useful customizations, and will even give you access to things that others don't even know are possible. Most FORSCAN changes are set and forget (usually).

I used Super Chips to change stuff.
Tire pressures, speedo recalibration, bambi lights, auto stop start. That was about all I needed
No Windows here either.

Only thing I needed to have someone else do was add sport mode to a Badlands.
A well-known member here took care of that for me

I bought that but had to return it. It only partially worked (turned off the honk). Turns out it was not coded for 2023's yet. That was 2 months ago. I should check them again.

I may try that. I read it's a pain compared to Superchips but superchips doesn't support a '23 bronco yet.

I generally run my 285/75 Toyos at around 36. Outside of chalk test - how do you determine what’s the ideal cold PSI after you change tire specs?

Good question. I don't have a way outside of the chalk test and a guestimate. I'm going for a broad contact patch when they are cold. Even that will change as they warm. It's looking to be in the low 30's psi. I think the higher Ford psi recommendations are driven by mpg but they make the ride rough.
