Electrical + PCM gurus.......
If I have a 13" fan attached to my condensor that I want to have running from engine start till the car reaches 45mph.
Can this be done through the PCM.....or is there another way to do it so its automatically being done.....?
Thanks...

But the fans also operate according to temps. So are you saying they really will just turn off at 65mph to let the ram air cooling take over? I never heard of the 35mph fans "ON" thing......
So how would I connect the additional 3rd fan thats attached to the condensor to operate by that 35mph/65mph speed schedule?
Is this something any good dyno tuner can do for me....?

You dont need fans on most if not any vehicle after 40 mph or so.. the oncoming air provides way more cooling than your fans... the fans on become a restriction at that point.. hence why theyre setup to shut off. The fans also consider the temperature.
So if the engine is at 200 degrees F, below say 40 mph (depends n tune) then fans will be on, if u pass 40 mph and engine is still at 200 *.. they will shut off.
To wire in a 3rd fan, use the fan signal pin wire to activate a relay to power your 3rd fan.. you can get it frm fan 1 or fan 2 and tune accordingly.

I think if the fan I put onto my A/C condensor would do great if it operated along with the dual radiator fans.....after 35-40mph they all 3 turn off, and rely on ram air cooling.
BUT......is it possible to make just the condensor fan always come on BELOW 35-40mph....regardless of coolant temp.....?

Thats what I thought the process was.....the fans would go off at around 35mph.....not 65mph. And of course...temp would be the master and turn them on any time a certain temp was reached.
Awesome....thanks for the info.
