I will be experimenting with a Chrysler hellcat brushless
Fan and e67 gmpp controller. I really hope it will actually work as I got the fan already mounted in my 68 lsa camaro. The hellcat brushless fan is looking for this signal: 12V PWM active LOW, 100hz. 10%DC is OFF, 90%DC is full on.
Don’t have acces yet to hp tuner or efi live to unable the pwm signal from discrete in my e67 controller. And from what I understand, the frequency can be altered with a efi live or hp. Is there anymore guys on here that got the brushless fans to work??
The hellcat fan is fairly inexpensive from dodge and it’s proven to work well without issues in hellcat family vehicles.

First post on the forum, and forgive me if I have missed this after reading through the entirety of the thread, but is it possible to still utilize the C6 PWM controller without an a/c pressure input? I do not have an a/c system installed on the vehicle.

This thread has been a wealth of information so thanks to everyone for contributing.
I have a Terminator X Max ECU, C6 fan, and Dorman 902-310 relay (mopar relay). I have tried a few different frequencies and have settled on 128, but there is a pretty noisy buzz from the fan. At 50% duty the fan and buzz noises are about equal, but below 50% the buzz is a bit annoying. Does the C6 relay have the same buzz? Anyone think it’s the mix of the Dorman relay and the C6 fan creating the buzz?
The C6 fan controller makes zero noise. I have never used the Dodge controller.
