You'll need an aftermarket PWM fan controller to do what you are asking.

You are correct apparently my ecu is not pwm compatible , my original set up came from 2005 Cts-v. I ordered a harness and ecu from psi assuming it would have pwm option. it works out because what I thought was a pwm control module from entropy is not. It turns both fans on at 50% w fan 1 on and than 100% when fan 2 kicks on .
What a mess but it works out .
Still fighting w code P0480 . Not sure what is triggering it .
