DSFM File Download (dealerconnection.com)
Basically lets you download calibration files from Ford as long as you know what filenames you're looking for. In this case I just incremented it from UM to UN on a whim. Nothing else past that up through UZ.
Curiously enough the timestamp on the UM calibration was dated for 8/27/2021, well before a lot of this stuff started rolling out to the public. UN is dated 3/9/22 so definitely very recent. Unfortunately no clue what changes there are.
EDIT: Looks like there's a matching strategy file out there as well. Same timestamp. I'll definitely be giving this a go sometime this weekend and will report back.
Calibration: HJ5T-14G139-UN (Dated 3/9/22)
Strategy: HJ5T-14G144-UP (Dated 3/9/22)
