Loss of Park Sense since T2 install

[warriorbahamut]

Hello im hoping to get some help please!
I have a 2021 Ram Sport 1500 and purchase and installed a Diablosport Trinity T2 with the PCM swap. Things seem to be all going good EXCEPT, my front and rear park sensors on the bumpers say unavailable. Called customer support and was told to try disconnecting battery, turning lights on, and hold brake pedal down for 3 minutes. Did that but still no fix. Anyone else have this issue or someone know what I can do to fix this? been a month now with over 300Km

after talking to diablotech for anyone having same issue future reference, it ends up that on the 2021 ram sport at least changing tire size to what you have messes with your front and rear bumper sensors apparently still. Until a fix is updated keep your tire size stock if your bumper sensors become "unavailable"

tough spot, but we've explored all options and there does not seem to be a workaround.
