Normally you will need slightly lower fan speeds at very low ambient temps and higher fans speeds in higher ambient temps to keep your ECT as stable as possible. There is more than one valid approach here, but I'm trying to use the ECT table as the primary table for regulating fan speeds/temperatures and I'm treating the others as modifiers/adders that will tweak my fan speeds based on other factors. You can leave 44002 as you have it and use the other tables to modify your fan speeds and get good results, but it would mean that referencing the values I posted earlier may not help you as it's more or less a package deal.
The fan and grill shutter tables that reference A/C head pressure and ambient temp set a minimum fan speed and shutter position based on those two factors. A/C head pressure should follow the chart posted below when the A/C system is running and working properly. Sorry for the low resolution image, that's all they have in the service manual. As you can see in the chart, with the A/C running in 70°F weather the head pressure should be between about 1200kpa and 920kpa. The column at 414 kpa can be all 0% as the A/C isn't running at pressures that low. You could also use this table or any of the others that reference ambient temp to set a minimum fan speed at 109.4°F regardless of ECT, TFT, or head pressure. It looks like your minimum fan speed is going to be fairly high even with very low ECT and TFT just because of high ambient temperatures and table 44000, this is how 44000 caused overcooling issues and large temperature swings for me.
No trouble at all. I work on cars for a living, but between the values being in kpa and my experience with newer r1234yf systems being fairly limited, the significance of the pressure values was completely lost on me until I did some research on Alldata.
What do y’all think is the best approach to dialing in the driver demand tables? Multiply the whole table by a %, adjust certain rows only, rescale any of the axis?
The driver demand table depends almost completely on driver preference. Just ensure the 100% pedal torque doesn't limit your torque demand, that's all. You can copy in different demand tables from whatever you want, like raptor, GT500, GT supercar, Mustang 2.3, even Raptor R. I wound up making my own because I like a strong mid-pedal torque curve so I'm at like 80% torque at 50% pedal.

I have a few different Raptor files to look at. Do you have a GT500 file to look at? I’m curious how Ford has it setup.
The gt500 was disappointing. It’s pretty much identical to the mustang gt except ramps up to full torque linearly past 50%. You can find the reads on hpt forums.

Thanks! If it’s not much different, I’ll try the same method as you described. I’ve currently got mine multiplied by a % and then set pretty high in upper ranges.
Can you explain why the base and launch tables should match? They don’t stock. I’ve read that the Baja table should match too, even though I don’t have Baja mode.
