What is the" Engine Calibration" on the 2020 window sticker?

[Guppydriver]

I was comparing sticker prices tonight and noticed that the 2020's with the 5.7 have a listing at the end of their sticker that lists "Engine Calibration" as a no cost option. The 2019's don't have this on the stickers I saw. When I say sticker, I mean the web version of the monroney sticker that dealers link you to.

Interesting.... What 5.7? I have a 2020 Rebel 5.7, non etorque and that Engine Calibration option does not show on my sticker.

I just checked the window sticker on my 2020 Bighorn with the non eTorque Hemi and I don’t see engine calibration listed anywhere either. Mine was built August 2019. Do u have a screenshot?

Shows on my 2020 Laramie 5.7 e-torque, which I hope gets here soon.

I wonder what the calibration is for?

My guess would be that Ram has a new PCM firmware that was dropped out of cycle so it needed to be manually applied to trucks before releasing them from the factory. The window stickers are dynamically printed using codes and I'll bet whoever's in charge, if they care, didn't know this would print out.
Pure speculation so carry on.

As long as we're guessing now, I think it might be for trucks destined for high altitude. SLC is 4000 feet+. I looked at a couple windowstickers online for trucks in inventory at the local dealer and they don't show it.

i have noticed that as well and one is for a fairly recent build.

Ah yes, the engine calibration PCM flash. Thats the super sexy way of saying that it runs the firmware that actually spins the radiator fans as opposed to the one I got.

It was a real treat to find out that "radiator fan strategy" was shorthand for... use the GD radiator fan before it boils off the coolant at a stop.
