Default Resistance vs temperature points for 1.6 AFM ?

I am sure this is well known, but I swear I've searched in every place I can think of and I can't find it.

Don't make me measure it. Anyone?

I need it for here:

I got this out of the enthusiast's manual:

-20C: 13,600-18,400
20C: 2,210-2,690
60C: 493-667

Is that for the MS2? I don't remember seeing that dialog.

Everyone says to use the RX7 defaults in Easytherm (which I know you don't have since you're MS2) so here they are:
-20C = 16,200
20C = 2,450
80C = 320


I can't vouch for these since I never ran the AFM (or its sensor) but nobody has complained so far.

These are the values we use.

-4 degrees F / 16000 ohms
68 degrees F / 2450 ohms
140 degrees F / 580 ohms

Thanks guys.
Yes, this is for MS2-Extra.
I guess I should do some sort of writeup when I'm done, since everybody else seems to be running MS1-Extra...
