I want to swap to e fans on my 2017 6 liter HD. I think they went to the E78 starting with the frame change in 2011...... I have found one thread where a guy attempted using HP to enable the fan outputs on his 2015 3/4 ton and was not able to get them to change state. Now whether he knew what he was doing or not I don't know but that's not cool if that is the case. The ECM in my truck is used on the 3/4 ton Suburbans of the same years and they have factory e fans..... so I assume it should work. Anyone tried with the E78 lol?????

I totally expect crickets.

I would want to do this as stock as possible....... GM even has the fuses for the E fans in place in the fuse block..... just no wiring and fans lol.
