Carl's controller is a standalone unit and so it doesn't need anything from the Holley EFI.

Correct. I was hoping that the Holley could do it, but if I have to buy a controller and possibly change fans it's easier to use Carls setup.

So after re-reading all 58 pages of this thread is there a consensus on if a late (2019-20) version GMPP connect & cruise E67 will work ? The last failed or maybe frustrating is a better term, efforts were back in 2017 if memory serves.

Has anyone had success lately? And if so, what was the fix? Other than of course sourcing a junkyard E67?

Thanks
Mike

Andrew, is this not the same as what you did with my Term X and my Spal brushless? Or something completely different and I should delete this.. lol

When using the brushless fan with the built in controller, you can go directly from the Holley to the fan signal wire.

Can someone confirm the part number for suitable fans to use with Holley EFI

What are the suitable fan options? C7 Corvette and any thing else.

This is for my 71 Blazer, but may also update on my 72 C10

thanks

There are many brushless fans that will work with the Holley EFI. It would be helpful to know the size of the core of the radiator you are using. On my 70 GTO I am using the dual Chevy Volt fans that fit the 26x18X core very nicely.

The core size is 16-1/8" H x 28-3/8" W. I have a preference to run a single fan

Will be using a Holley Terminator Stealth
