E92 fan relay control?

[LS-SWAPPER]

Is it common knowledge that the e92 ecms cannot support series/parallel fan relays in the traditional sense? Perhaps I am the last to know. They look to be PWM only, or am I missing something? I didn't see a Patch either.

PWM only.

So the next question is what PWM fan controller should we use? I hear that some have used a corvette controller, but I haven't found any more specifics. I am fairly familiar with the C6 controller as I had to replace one that was damaged once. Is there any reason on of these wouldn't work with the e92? AC Delco 1580803

That’s up to you. Personally I’ve used many different ones, even a Chrysler one from grand cherokees.
