I was looking at calibrations for my 2015 GMC Yukon Denali's ESCM (Z95) and noticed there's a listing but the calibration ID's are not sequential and the latest one it recommends is a lower numerical value than the one that may fix an issue I have. Is this normal? Any explanation for the ordering?
I posted this in the K2XX forum but this one appears more appropriate so sorry for the spam.
I believe I have the original calibration and think 23452750 may fix my issue. Does the "current"/top one include all the fixes in the below or are they all different and you pick the one that addresses your issue?
I won't be applying this, likely taking to the dealer and just want to be informed.
