Ok...this is starting to make some sense now.
The SPAL fans are identical, and are not brushless.
Driver(primary) / passenger(secondary) side pulling air through the heat exchangers.
So I have three desired states triggered by temperature:
1- both OFF
2- Primary ON secondary OFF
3- Primary ON secondary ON
I'm guessing the "state" of 0 thru 7 is temperature increments.

"1" up in the header row is apparently 203F as that is currently when both fans turn on. Where can I find the corresponding temps for 2 - 7?
Am I correct that the transition desired vs current state table only applies to PWM fans? Or does it need the two ON states populated into it accordingly?

I'm obviously not thinking about this in the same way as the software is set up because the desired fan % vs ECT table has more than 8 (0 thru 7) increments.

So how do I set the secondary fan to turn on at 225F?
And how do I see when each fan turns off as ECT declines?
