I called the place building the radiator and was told the same thing but they'd see what, if anything, they could find out because they have not installed in a 2010 Camaro.
Dave Steck (DSX Tuning) is a friend of mine and I contacted him about it. He said the Corvette and Camaro E38 OS are the same but have differing CANbus communication. He said he sees no reason I can't control the fans with PWM because the OS has PWM Electric as a choice. That is a screenshot of my actual tune showing it.
Unless I missed something in this thread (quite possible) I haven't seen anyone successfully running PWM in a 5th Gen Camaro and an E38 ECM.
It would be nice to be able to just drop the new fans in, connect the wires and go.
ETA: I don't know which fans I'm getting as the place (wizard cooling) is going to use the biggest ones that will fit. 14" diameter and 3. 25" thickness was mentioned. I am not aware of any other aftermarket 5th Gen radiator having 14" fans though.

Was you able to get this working?
I am installing the following setup in my 1976 Blazer.
L99 DOD delete with 6l80e from a 2015 Camaro
I have 2-12" Spal Brush-less fans part numbers 30107087 VA89- ABL320P/N-94A
I also have vintage air.
Looking at the wiring diagram for the brush-less fans it appears that they do not run throw a relay. It says to just install a 40 amp Maxi Fuse.
I am wanting to hook these up to run PWM so that they are variable speed like a new car. I would like the fans to be controlled by my e38 ecm. I am also installed a pressure transducer on the ac line.
With the 2 fans do i need 2 controllers?
