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.

Cheers,
Sergio
