Hey guys,

I'm just sharing this with you if you're having problems resetting the tire pressure thresholds. The stock tire pressures as you know are F60 and R80. I personally hate the ride of the F250 and am trying to soften the road a bit. I tried modifying the values based on the Youtube video produced by CJC Off-Road. This involved changing the BCM AS_Built 726-40-01. They recommended using code 2828 for 45 PSI front and rear. 28 is hex code for 45 and I checked this using a number to hex converter. This failed to write every time right around the 51% mark.

I went to the regular BCM (not AS_BUILT), changed the psi to F50 and R60.

This not only saved but automatically updated the BCM AS_BUILT 726-10-01 & 02 respectively. 32 is hex for 50 and 3C is for 60.

I could not find on any spreadsheet or forum that you only need to change the regular BCM and the AS_BUILT automatically updates.

We’re you ever able to adjust the TPMS on the 2020? I’m wanting to do the same
 
I just did mine, set front and rear to 50psi, changed the startup screen to the bronco offroad display, made the led halos much brighter, and set it to keep fogs and high beams on at same time, as well as the flood lights in mirrors to turn on at any speed.

I didn’t know you could do mirror floods through forscan?

yup, there is much more you can do too, like accelerometer, 0-60 times, line lock, whole bunch of shit I didnt mess with that we may in the future...

Details/instructions on mirror flood light at any speed?

im an idiot, he didnt use forscan for that mod. You go to the green plug for the mirror module, and jumper wire bypass the module. if i can get a chance ill take a pic of mine and PM it to you.

i mispoke, your right you cant. He bypassed the module with a jumper wire in the mirror plug.
