I just got my 17" brushless fan and I am going to try to figure out how to have my factory ECM control it. Since these brushless fans are supposed to be factory on the 2014+ Corvette, I was able to compare the 2014 tune for brushless fan against the pre 2014 fans that have a separate PWM controller as seen in this thread.
In HPTuners the 2014 fan is listed as a PWM EV fan operating at 100Hz where the pre 2014 fans are PWM electric operating at 128Hz.
I'm thinking that I can just change the fan type and frequency in my tune and it should work.
Any thoughts?
