Efan questions for the 8.1L

That's a nice setup, I may have to go that route some day. Looks like your fans for ac are only controlled by ac pressures (which I like), but I don't understand why fan1 and fan2 have different turn on pressures, unless they run at different speeds or something?. I also like that there is a fan turn off speed (don't need my fan running when I'm cruising down the highway at 80mph lol). I don't understand what the "Fan #1 Turn on by AC Temp = 224" is all about though

I am not an A/C guy but i assume that as the temps rise across the condenser, the pressure in the system rises as well? As far as the "fan #1 turn on by A/C" is concerned, it must be a fail safe i guess because the other switches would be satisfied way before that comes into play.
Yes they are kPa values.

Sorry, have not checked this thread in a while so I know the questions are old.....sorry....
It got rid of the terrible rushing air sound that you get when the fans kick in. Since I have picked up the other 8.1L (daily driver truck) there is a pretty big difference between the two in the way it feels when you take off from a light with the mechanical fan engaged. I did not notice much (if any) of an hp/tq gain....but now that I have the other truck to compare it too, I would say there is definately some difference....just not sure how much.

I have thousands of pictures.....anything in particular?
