Thom is using a E92 ECU that came with a GM LT4 connect and cruise. That ECU and harness is set up for two discrete outputs and are already wired to relays in the Chevrolet Performance fuse box.

I also want the answer to this for this application.

Just so it is all on the same page.

Any one have any success controlling the PWM fan as intended?

Thank you in advance.

I have no direct experience with what you are doing, but I have some educated guesses. From what I understand, the ZL1 fans have the controller built into the fan. The connector (Yazaki) has two large pins for power and a small pin for the PWM signal wire. Again, from what I understand, you should be able to configure the ECM to send a PWM- signal to the fan and it should work. I would use the same settings of 128Hz and input the duty cycle table as with the C6 Corvette application.

I wish I had one of these fans to experiment with. I'd like to see if they would work with the Holley ECU.

I don't see why it wouldn't, it wants the same PWM signal.

The crew at V8 Speed said on a FB post that the GMPP E92 for the LT4 is programmable to run a pwm fan signal.

I am waiting for a couple of corroborating experiences, it is costly to undo.

Don,

That looks like one of the fans from a 5th gen Camaro. I believe that if we are talking about the e92 ECU, then that would be the 6th gen Camaro...

No need for apologies. I am just trying to keep all of this information as accurate as possible. We're all learning here...LOL

Adapting new OEM parts to our old clunkers is not easy, but I think there are many benefits to be had. As I understand it, the new fans are quite amazing!

You know we're in deep when we're using words like AMAZING to describe cooling fans... LOL

Geeks-R-Us...LOL

In all honesty, PWM fan control adds a great deal of refinement out our old cars. The information from this thread allowed me to implement it on my Cougar build and it truly is AMAZING! On my GTO, I am using dual Spal fans with binary fan control. The car has a relatively quiet exhaust and when the cooling fans turn on, it sounds like a jet engine.

On the Cougar, I never hear the fan, ever, and I have yet to see it go much above 50% duty cycle even on hot summer days. The C6 fan is rated at 400watts, while the new 6th gen Camaro fan, I believe is 800watts! So yes, amazing.
